Plpgsql Syntax Error

PL/pgSQL variables will be substituted into the rest of the query, and the plan is cached, just as described above for commands that do not return rows. Because quote_literal is labelled STRICT, it will always return null when called with a null argument. Executing a Command With No Result For any SQL command that does not return rows, for example INSERT without a RETURNING clause, you can execute the command within a PL/pgSQL function Thus, a function with conditional code that contains many statements for which execution plans might be required will only prepare and save those plans that are really used during the lifetime my review here

Missing quotes around function body. Likewise, functions having polymorphic argument types have a separate plan cache for each combination of actual argument types they have been invoked for, so that data type differences do not cause

For WITH queries, use PERFORM and then place the query in parentheses. (In this case, the query can only return one row.) PL/pgSQL variables will be substituted into the query just because PL/pgSQL will not substitute a variable for a trailing component of a qualified name.

You can avoid this problem by using CREATE OR REPLACE FUNCTION when updating the definition of my_function, since when a function is "replaced", its OID is not changed. Note in particular that EXECUTE changes the output of GET DIAGNOSTICS, but does not change FOUND. Movie about a board-game that asks the players touchy questions How to explain the existence of just one religion? useful reference SELECT INTO is not currently supported within EXECUTE; instead, execute a plain SELECT command and specify INTO as part of the EXECUTE itself.

Customarily it is written either just before or just after the list of select_expressions in a SELECT command, or at the end of the command for other command types.
