Use raise notice to Print Variable Value in PostgreSQL Thus an EXCEPTION clause nested within that handler could not catch it, even if the RAISE was within the nested EXCEPTION clause's block.

You cannot call RAISE dynamically (with EXECUTE) in PL/pgSQL - that only works for SQL statements, and RAISE is a PL/pgSQL command. in postgres, I wrote a simple procedure as below. You will find list of RAISE INFO messages that we mentioned in above function. If the message needs some variable values to be printed with it, the % sign is used. A variable holds avalue that can be changed through the block. By default, NOTICE is always returning to the client only. Instead, define all parameters, maybe add defaults: Thanks for contributing an answer to Stack Overflow! PostgreSQL provides a "type" called the record that is similar to the row-type. This form is used for PL/pgSQL functions that do not return a set. The data type can be any valid data type such as, Third, optionally assign a default value to a variable. Step 2 : Create a function using PLTCL to declare the Global Associative Array and set a value. PostgreSQL provides level option to specify with RAISE that specifies the severity of the statement. We no longer have to pass in a goofy 0 for depth. Withdrawing a paper after acceptance modulo revisions? If no message text is specified, the default is to use the condition name or SQLSTATE as message text. Variable: A variable holds a value that can be changed through the block. Use this simple function instead: CREATE OR REPLACE FUNCTION f_raise (text) RETURNS void LANGUAGE plpgsql AS $func$ BEGIN RAISE EXCEPTION '%', $1; END $func$; Call: SELECT f_raise ('My message is empty!'); Related: To learn more, see our tips on writing great answers.

Here is an example: In this example the data type of the variable eid_var is declared by reference to the eid columns data type in the emp table As output the user wants to return a complete row (all columns) of the emp table, so the variable result is declared as a reference to a whole row type of the emp table. This example will abort the transaction with the given error message and hint: These two examples show equivalent ways of setting the SQLSTATE: There is a second RAISE syntax in which the main argument is the condition name or SQLSTATE to be reported, for example: In this syntax, USING can be used to supply a custom error message, detail, or hint.
