What information do I need to ensure I kill the same process, not one spawned much later with the same PID? . return true; A trigger function is created with the CREATE FUNCTION command, declaring it as a function with no arguments and a return type of trigger (for data change triggers) or event_trigger (for database event triggers). PL/pgSQL is one of the most popular procedural languages in PostgreSQL. Possible levels with RAISE are DEBUG, LOG, NOTICE, WARNING, INFO and EXCEPTION. RAISE EXCEPTION is slightly different. *** Please share your thoughts via Comment ***. Mike Sipser and Wikipedia seem to disagree on Chomsky's normal form. The % sign acts as a placeholder and is replaced by the variable value given with the RAISE command. You can see from above that PostgreSQL took care of transforming the number to a string to attach it to the rest. Previously Allowed levels are DEBUG, LOG, INFO, NOTICE, WARNING, and EXCEPTION, with EXCEPTION being the default. is a simple example of that. I have more than six years of experience with various RDBMS products like MSSQL Server, PostgreSQL, MySQL, Greenplum and currently learning and doing research on BIGData and NoSQL technology. The way to to this in plain SQL is to use a CTE (which is also a cross platform solution and not tied to any SQL dialect): with vars (foo) as ( values ('bar') ) select foo from vars; RAISE without level, exception handler present, program executes successfully. The first_name and last_name are varchar(50) and initialized to 'John' and 'Doe' string constants. Example: I doubt you need a VARIADIC parameter for this at all. This can be used multiple times. You cannot call RAISE dynamically (with EXECUTE) in PL/pgSQL - that only works for SQL statements, and RAISE is a PL/pgSQL command. Providing the best articles and solutions for different problems in the best manner through my blogs is my passion.
