default. EXCEPTION raises an error (which normally aborts the current transaction); the other levels only generate messages of different priority levels. Whether messages of a particular priority are reported to the client, written to the server log, or both is controlled by the log_min_messages and client_min_messages configuration variables. See Chapter 18 for more information. After level if any, you can write a format (which must be a simple string literal, not an expression). The format string specifies the error postgresql raise notice multiple variables message text to be reported. The format string can be followed by optional argument expressions to be inserted into the message. Inside the format string, % is replaced by the string representation of the next optional argument's value. Write %% to emit a literal %. In this example, the value of v_job_id will replace the % in the string: RAISE NOTICE 'Calling cs_create_job(%)', v_job_id; You can attach additional information to the error report by writing USING followed by option = expression items. Each expression can be any string-valued expression. The allowed option key words are: MESSAGE Sets the error message text. This option can't be used in the form of RAISE that includes a format string before USING. DETAIL Supplies an error detail message. HINT Supplies a hint message. ERRCODE Specifies the error code (SQLSTATE) to report, either by condition name, as shown in Appendix A, or directly as a five-character SQLSTATE code. COLUMN CONSTRAINT DATATYPE TABLE SCHEMA Supplies the name of a related object. This example will abort the transaction with the given error message and hint: RAISE EXCEPTION 'Nonexistent ID --> %', user_id USING HINT = 'Please check your user ID'; These two examples show equivalent ways of setting the SQLSTATE: RAISE 'Duplicate user ID: %', user_id USING ERRCODE = 'unique_violation'; RAISE 'Duplicate user ID: %', user_id USING ERRCODE = '23505'; There is a second RAISE syntax in which the main argument is the condition

Inside the format string, % is replaced by the string representation of the next optional argument's value. Write %% to emit a literal %. The number of arguments must match the number of % placeholders in the format string, or an error is raised during the compilation of the function. In this example, the value of v_job_id will replace the % in the string: RAISE NOTICE 'Calling cs_create_job(%)', v_job_id; You can attach additional information to the error report by writing USING followed by option = expression items.

- NOTICES, http://www.postgresonline.com/journal/archives/83-Quick-Guide-to-writing-PLPGSQL-Functions-Part-3-NOTICES,-RECURSION,-and-more.html RECURSION, and more Printer Friendly In this third part of our PLPGSQL Quick Guide series, we shall delve into writing recursive functions. Before we do that, we shall demonstrate a very important but trivial feature in PostgreSQL and that raise notice is the RAISE NOTICE feature. There are more elegant ways of debugging, but this is the simple brain dead way of doing so. RAISE RAISE Notices in plpgsql are generally used for two reasons: As a simple debugging tool postgresql exception handling to output state variables in a function call. As a WARNING to a user to inform them of important things such as this function is deprecated and should not be used or they are using something in an incorrect way. A simple example of notices and recursion is shown below. Admittedly I couldn't come up with a more pointless example to demonstrate recursion: CREATE OR REPLACE FUNCTION fnsomefunnote(param_numcount integer) RETURNS integer AS $$ DECLARE BEGIN IF param_numcount > 0 THEN RAISE NOTICE 'Yo there I''m
