问题 I found this article: http://wiki.postgresql.org/wiki/Return_more_than_one_row_of_data_from_PL/pgSQL_functions and I'm trying to use it as an example for my function. I am selecting different columns from different tables, and trying to return a set of records. Here's my code: CREATE OR REPLACE FUNCTION get_details_for_widget(widgetid integer) RETURNS SETOF widgetdetails AS $BODY$ DECLARE rec widgetdetails %rowtype; BEGIN FOR rec IN ( SELECT widget_details.id, widget_details.contact_id,

问题 I have spent good amount of time trying to figure it out and I haven't been able to resolve it. So, I need your help please. I am trying to write a PL/pgSQL function that returns multiple rows.

Fist way : CREATE OR REPLACE FUNCTION translateToReadableDate(mRecord dim_date%ROWTYPE) RETURNS void AS $$ That is the ouput : psql:requestExample.sql:21: ERROR: syntax error at or near "%" LINE 1: ... FUNCTION translateToReadableDate(mRecord dim_date%ROWTYPE) ... ^ Second way : CREATE OR REPLACE FUNCTION translateToReadableDate(mRecord RECORD) RETURNS

问题 I have a table called evidence with a trigger which calls a stored procedure which basically does table partitioning by month. However I get an obscure error when I start inserting lots of rows under load: Npgsql.NpgsqlException: query string argument of EXECUTE is null Severity: ERROR Code: 22004 at Npgsql.NpgsqlState.<ProcessBackendResponses_Ver_3>d__a.MoveNext() in c:\C#Apps\github.npgsql.Npgsql.stock\src\Npgsql\NpgsqlState.cs:line890 at Npgsql.ForwardsOnlyDataReader.GetNextResponseObject(

问题 I got some SQL function CREATE OR REPLACE FUNCTION tools.update_company(IN company_id integer, OUT value integer) RETURNS integer AS $BODY$ BEGIN select * into value from function_making_int(company_id) END;$BODY$ and from Psycopg2 (its inside Django if that matters) I do c = connection.cursor() c.callproc('tools.update_company', [1, ]) but function returns exactly the same input sequence as I gave, ignoring results and OUT parameter. Change to IN OUT and passing some foo value changes

问题 I have a query string generated in a postgres UDF, i'd like to put it's result in a temp table to perform joins against (I'm using LIMIT and OFFSET , and I don't want to join against other ttables only to end up choping the data off at the end --i.e., the LIMIT operator in the query plan). I attempt to create the temp table with the following statement. CREATE LOCAL TEMP TABLE query_result ON COMMIT DROP AS EXECUTE query_string_; But I get the following error notice : ********** Error *******

问题 I am new to PostgreSQL and am using the query tool in PGAdmin. I'm trying to run pgsql queries that use variables, but I can't seem to get the syntax right. Here's a sample query that gives a syntax error: DECLARE num INTEGER; BEGIN num := 3; PRINT num; END; Update: Ok, let me try and explain. I come from a SQL server background.
