I think it won't like spaces much either. 2003/11/03 00:16 EST (via web): Calling this function is a little more complicated than calling the SRFs above. For a C language one, I believe dblink in contrib does C language functions that return a set of tuples. This limitation may be removed in a future version. by Stephan Szabo The PL/pgSQL function is a little more complicated, but let's go through it. 2003/10/24 17:31 EST (via web): This tutorial must become part of Postgresql Function Documentation, with more examples in many other languages than SQL and PL/PGSQL such as Python, Perl, C, etc... 2003/04/24 16:44 EST (via web): Thank You. 2003/05/29 08:00 EST (via web): This function returns a set of integers (department ids) rather than a set of a composite type because we only need to return the id for the expensive departments. special case for a single column output. Please keep on adding to this section. Yes, I agree.. I tried building the string as SELECT baz_number FROM baz_table WHERE customer_id = ' || cust_id || ' - no dice. Click here. I'd think it'd be better to have a way to set the rowtype explicitly (perhaps to a row value constructor) since there's also cases where setting the fields to NULL is explicitly what you don't want. 2003/04/04 15:21 EST (via web): To Warmage: In 7.3, I believe you can make a function return void if you don't want to use its value. I have a table called "events" and anoteher called "event_parameter" and some other tables that are also conected with these two. The name of a table it acts > on is one of its input variables, and its output is a set of rows > from that table. Are you calling it like select GetNum(1); or select * from GetNum(1); ? Perhaps you could use triggers, https://wiki.postgresql.org/index.php?title=Return_more_than_one_row_of_data_from_PL/pgSQL_functions&oldid=17343. Using OUT and INOUT function arguments. The following simplified example shows what I'm talking about (I know this could be done with sub-selects, but in more complicated cases it must be done interatively): 2003/04/24 16:48 EST (via web): See: 2003/06/26 04:31 EST (via web): As for status return, if there's an error (excepting a foreign key violation that is not yet checked - like deferred constraints) right now the statement will be ended so it won't get to the next statement in the function. Is there any way to get the n-th item in a record? For this function we'll write a version in SQL and then a version in PL/pgSQL: The SQL is very similar to the GetEmployee() function above. A simplistic example: create function pfoo(int) returns setof int language 'plpgsql' as 'declare b alias for $1; x int; begin for x in 1..b loop return next x; end loop; return; end;'; create function foo(int) returns setof int language 'sql' as 'select * from pfoo($1)'; select 1, pfoo(5); /* will give you an error */ select 1, foo(5); /* works */ (sorry for formatting this text box is tooo wide and tooo short...). 2003/05/27 11:31 EST (via web): On Wed, 18 Dec 2002, Toby Tremayne wrote: > -----BEGIN PGP SIGNED MESSAGE-----> Hash: MD5>> Hi all,>> I've been beating my head against the desk for days on this, and> I've been completely unable to find docs on it. In this example, we created the get_film(varchar,int) that accepts two parameters:. cases it must be done interatively): sszabo, 2003/05/15 19:18 EST (via web): Thanks, 2005/08/02 10:54 GMT (via web): #include function with multiple return values [email protected] It would be really nice if someone (other than me) with a bit of spare time would hit the "Edit this page" link at the top of this page and fix up the comments and properly line up the examples. My original problem is that the function takes one parameter of type regclass as input and returns a setof records (the row type of the corresponding input regclass). I agree This document should be in PostGre documentation. We could also use RECORD. Specify the argument list in the function if the function is overloaded. PostgreSQL 7.3 now supports a much more flexible system for writing set returning functions (SRFs) that when combined with some of the new function permission options allow a greater flexibility in setting up schemas. 2003/06/30 08:25 EST (via web): > > I have a function returning setof record. There is another approach to doing this, and that is to use the ANSI Standard RETURNS TABLE construct. I've tested this with 4 levels of recursion so far and its worked, so I believe it is correct. Perfect! Let's make a function that returns all the rows of a table whose name you pass in as a parameter. PostgreSQL Database Forums on Bytes. Hello! Add your comments here... 2003/04/17 05:53 EST (via web): This tells PostgreSQL that you want to the function to return an composite type but that you're going to tell it what types to expect later. al.) In fact, it's a dammage to declare a type with explicit type when we already knows the type return by the function. E.g. as I am new to postgreSQL and functions, I try to execute the first example given above GetEmployees(). In this case I cannot create a wrapper function since the return type is known only at the execution time, can't I? (2 replies) I am porting some Oracle code to PLPGSQL and am having a problem with functions that return SETOF datatype. One of my tables has a recursive relationship. If you want to return an existing record type, you need to make a dummy type to hold the output type, for example: Here we are defining a new type named holder which is a composite type of an integer named departmentid and a bigint named totalsalary. The SETOF modifier indicates that the function will return a set of items, rather than a single item. If you make a mistake, you'll get an error at creation time for SQL functions and at execute time for PL/pgSQL functions. Does someone know what is wrong with the example? al.) Notice that if we were to carry out this logic without stored functions we would have to make several round trips to the server to achieve our goal. 2003/10/14 18:11 EST (via web): i'm calling it as select * from GetNum(1); 2003/06/04 08:12 EST (via web): A PL/pgSQL function can also do additional operations on the records or only queue up only some records. [Maybe: SELECT * FROM c_fcn() AS (a int, b text);]. When you use the function, you need to say something like: select * from func() as foo(col1 int, col2 varchar, ...); Since it's an arbitrary record type, it doesn't know what the types are, so you need to provide it at select time. Obtaining a ResultSet from a stored function. Note that for the return next we are not returning the record r, but instead are returning just the departmentid because this function returns a set of integers. quote_literal() was the solution. Writing a function that returned the most current row for any given entry point was a little tricky as nothing mentioned recursion that I saw. Check out the sections of the manual that talk about PLPGSQL.... 35.7.1. Fixed the ANNOYING formatting of this page. The ‘RETURN QUERY’ keyword is used to return the type ‘SETOF sales’, since we’re returning a set of records we execute a select statement to return the necessary records. The table would have 3 columns and an unknown number of rows. Add your comments here... ), but when I use the function code> below I get the error:>> ERROR: A column definition list is required for functions returning RECORD. Just a quick note for a problem I was having. Here it is again. I've tried the following using PostgreSQL 9.2: CREATE OR REPLACE FUNCTION test() RETURNS SETOF record Which gives me the following error: ERROR: a column definition list is required for functions returning "record" I've also tried: CREATE OR REPLACE FUNCTION test() RETURNS table () Returning From a Function There are two commands available that allow you to return data from a … Use drop function statement to remove a function. Dynamic, using AS (name type, …) at call site : SETOF RECORD. Copyright © 1996-2020 The PostgreSQL Global Development Group, [email protected], return setof record from function with dynamic query, Re: return setof record from function with dynamic query, Stephan Szabo , Toby Tremayne . Question about functions that return a set of records Group by clause creating "ERROR: wrong record type supplied in RETURN NEXT" (version 8.1.11 -- grr...) Function Returning SETOF RECORD: Trouble With Char Type Here is an example of my probem : I have created the tables and records as shown above but I cant get the function run. Sorry, forgot the pre /pre around my code. We need to give the system an idea of what types we expect this function to return as part of the query. > First it was defined to return SETOF someview. If I give a SELECT GetEmployees(); There seems to be some limitation with plpgsql that prevents you from using a set-valued function in the SELECT list of a query. The first version uses a pre-defined type as its return type and internal type. You have to do something like (given r as record type and returning setof record): select into r 1::int as num, 1::int as doublenum; before using r in the for loop. We're going to work with a very simple set of tables and data and functions written in SQL and PL/pgSQL. Related (you linked to that one yourself): Refactor a PL/pgSQL function to return the output of various SELECT queries; FOR-IN-EXECUTE to loop over a dynamic query. > > > I have a plpgsql function that returns dataset. Here we're figuring out the total salary plus the overhead and updating the record appropriately. INSIDE function. So far, the composite type returning functions only work if you're certain that you're returning a type that is made up of the same types as the one the function is declared to return. If present, it must agree with the result type implied by the output parameters: RECORD if there are multiple output parameters, or the same type as the single output parameter. 2003/02/27 11:27 EST (via web): It returns a rowset of rows defined by the type holder (int, int8). Finally, we're going to make PL/pgSQL functions that synthesize rows completely from scratch. SRFs can return either a rowtype as defined by an existing table or a generic record type. If we instead had wanted to return a holder to include the salary + overhead value, we could have defined the function to return setof holder and used return next r; here. quote_literal() was the solution. E.g. 2003/06/26 12:13 EST (via web): 2003/05/28 11:34 EST (via web): CREATE OR REPLACE FUNCTION wordFrequency(maxTokens INTEGER) RETURNS SETOF RECORD AS $$ BEGIN SELECT text, count(*), 100 / maxTokens * count(*) FROM ( SELECT text FROM token WHERE chartype = 'ALPHABETIC' LIMIT maxTokens ) as tokens GROUP BY text ORDER BY count DESC END $$ LANGUAGE plpgsql; If you call your set-returning function the wrong way (IOW the way you might normally call a function), you will get this error message: Set-valued function called in context that cannot accept a set. I need a Postgres function to return a virtual table (like in Oracle) with custom content. Functions returning setof record -- can I use a table type as my return type hint? A caviat: if you are dealing with a WHERE clause in the EXECUTE SELECT, you may want to quote_literal() your string variables (if they are being passed in). Does anyone have an example of a C function which returns a SETOF RECORD? Using Function returning setof record in JOIN; Why I need to use SETOF TEXT when I'm returning single column? You can't do it in 7.2. It's very important tutorial because many people don�t know how crete that type of functions(procedures), and the way to make it on PostgreSQL is so diferent with other RDBMS such as MSSQL, ORACLE, INFORMIX, INTERBASE/FIREBIRD etc.. The key point here is that you must write RETURNS SETOF record to indicate that the function returns multiple rows instead of just one. Use the drop function statement with the cascade option to drop a function and its dependent objects and objects that depends on those objects, and so on. Technically I think you still get a result set containing a NULL, but you don't have to use a final select. I run into this most often when creating complex pivot tables that do not use agrigates. 2003/10/24 05:22 EST (via web): DECLARE row variable of ROW or RECORD type. So, when we implemented support for table-valued functions, we only supported those that return a TABLE type, in jOOQ 3.5. jOOQ 3.6 will also support SETOF functions. > But, I get the following error:"ERROR: a column definition list is required > for functions returning "record" SQL state: 42601". old records-> new records. What I want is to creat a function that will manage these tables when an event occures. Imagine this: CREATE OR REPLACE FUNCTION 'public'. I would like to see 'return next' push the return row, then set all columns to null, ready for fresh data. This becomes an issue when denormalizing data which is too complex to handle with a select, and so must be done with nested 'for select in' loops. Its a great HELP!!! The body of the loop is the new return form, 'return next' which means that an output row is queued into the return set of the function. ...it would still be nice just to see how the last example could be done with a RECORD type. The SETOF modifier indicates that the function will return a set of items, rather than a single item. For example, if you wanted to get an idea of operating expenses for departments where the overhead is 75% for departments whose total salaries were greater than 70,000 and 50% otherwise and only wanted to return department ids for departments whose salaries plus overhead was greater than 100,000 you might write something like: Let's look at the differences between this and PLpgSQLDepartmentSales(). Assignment of a yet-unknown column with the hstore operator #=. Thank you. I get a list of obvious numbers. The following simplified example shows what I'm talking about In fact setof implies that I know the kind of record, but this information is know only at runtime. This page was last edited on 19 May 2012, at 09:40. Last updated 4th April 2003. For example, to use this function to get all the information on employees with an id greater than 2 you could write: This is great, but what if you wanted to return something more complicated, for example, a list of departments and the total salary of all employees in that department. Here we've passed in Department as the argument which means that we expect to get rows in the general form of Department records which is an integer followed by a text string, so we tell PostgreSQL that the alias for the result should be called dept and that it is made up of an integer named deptid and a text named deptname. PostgreSQL treats these functions somewhat similarly to table subselects and uses a similar syntax for providing this information as one would use to give aliases to subselect columns. From: To: pgsql-sql(at)postgresql(dot)org: Subject: plpgsql function returning SETOF RECORD Question: Date: 2004-02-23 13:21:32 Turns out selecting into r and calling next fixed that. An SRF can be used in place of a table or subselect in the FROM clause of a query. you can do "select foo, set_of_things(bar) from mytable" if set_of_things() is an SQL function, or a C function apparently - this started from trying to figure out how the int_array_enum() function in contrib/intagg got away with it - but not if it's a PL/pgSQL function. RECORD structure. We can do the same thing using a record type so that we do not need an outside type, however it is much more complicated and involves a bogus select. The rows that it returns are defined by the group by query in its body. PostgreSQL's™ stored functions can return results in two different ways. 2003/10/15 03:23 EST (via web): The name of a table it acts on is one of its input variables, and its output is a set of rows from that table. 2003/04/01 18:21 EST (via web): What is the difference between the return of … I have a function returning setof record. The function starts off by declaring a variable r to be of the rowtype holder. Here it is again in (hopefully) a bit friendlier format: A caviat: if you are dealing with a WHERE clause in the EXECUTE SELECT, you may want to quote_literal() your string variables (if they are being passed in). SETOF anyelement - get_call_result_type; set returning function with variable argument - possible? In that case, you can return a setof record. Is there a way to have a function return an agregate of custom types? It give me this error: WARNING: Error occurred while executing PL/pgSQL function getnum WARNING: line 8 at return next ERROR: Set-valued function called in context that cannot accept a set Is there any one can tell me what wrong with it??? The following is what I did. But If I give a SELECT * from GetEmployees(); Technical Assistance is available through the PostgreSQL Mailing Lists, available here: http://www.postgresql.org/community/lists. Someone had wrapped their entire comment in pre /pre and made the page layout confoundingly wide. Add your comments here... 2005/07/11 16:59 GMT (via web): The function makes a variable of the rowtype numtype and for each number from 1 to the passed argument assigns num and doublenum and then does return next r; in order to enqueue a row of output. Newbie: This article requires PostgreSQL version 7.3 or greater. I think it won't like spaces much either. Let's break down this function. For example: Without quote_literal(), the query tends to choke on special characters (like colons, dashes, et. [/QUOTE] That single predicate, "multiple output parameters", is creating the (useless?) These functions are used in the same fashion as the first function. ; The p_year is the release year of the films. That might be ok. [tablefunc.c does this, but for a ROWTYPE, not a RECORD] What would be the syntax for calling this? SETOF From type definition. The function may return either a refcursor value or a SETOF some datatype. For the longest time I was stuck on getting 0 records back. It's pretty simple. The p_pattern is used to search for films. If someone know that please contact me at: [email protected] In a prior article Use of Out and InOut Parameters we demonstrated how to use OUT parameters and INOUT parameters to return a set of records from a PostgreSQL function. I tried building the string as SELECT baz_number FROM baz_table WHERE customer_id = ' || cust_id || ' - no dice. GREAT!!! The type of a column is referenced by writing table_name.column_name%TYPE. However, that does give you a workaround: you can call the PL/pgSQL function *from* an SQL function. In Oracle, the functions I'm porting return a TABLE of TYPE datatype, this TABLE being itself a named type. Note that if you don't fill in all the values for the return type for each return next, old values will be used, so you have to manually null them. create or replace function get_current_rec(numeric) returns setof rec as ' declare r rec%rowtype; begin for r in select a, b, c, d as total from table where key = $1 loop if r.replaced_by IS NULL THEN return next r; ELSE raise notice ''trying to fetch record for %'',r.replaced_by; select into r * from get_current_rec(r.replaced_by); return next r; end if; end loop; return; end ' language 'plpgsql'; We can then define functions that return sets of this type. I'm new in working with PostgreSQL!! So you are not bound to use SETOF with polymorphic types like you speculated. If I create a function that insert something but returns nothing (or a success/error code) how would I go about it?

If you came here wondering how you can return multiple values from a function (like in Oracle PL/SQL): CREATE FUNCTION temp() RETURNS record DECLARE v_record RECORD; BEGIN select 1, 6, 8 into v_record; return v_record; END; Then you do: select * from temp() as (int4, int4, int4). 2003/10/17 19:26 EST (via web): But what happens if you only know what the details of the composite type the function needs to return at execution time? If you come from a SQL Server or IBM DB2 background, the RETURNS TABLE construct is probably most familiar, but still … Calling function GetRows(text) error: testdb=# select * from GetRows('department') as dept(deptid integer, deptname text); ERROR: parser: parse error at or near "(" testdb=# why? The return type of the function is setof employee, meaning it is going to return a rowset of employee rows. 2003/04/24 14:52 EST (via web): I assume in this that you already have some experience with writing functions in SQL and PL/pgSQL for PostgreSQL. 2003/04/17 03:39 EST (via web): The following illustrates how to call the get_film() function: 2003/10/24 16:45 EST (via web): > ERROR: A column definition list is required for functions returning RECORD.
