Below is an example that demonstrates, FOUND, storing sql values in temp variables, and more recursion. SUMMARY:This article covers how stored procedures can make use of variables to be more functional and useful. We should break down our code into smaller parts and add RAISE statement with clock_timestamp(). <> By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy.

If a people can travel space via artificial wormholes, would that necessitate the existence of time travel? stream With that said we can make our function a bit nicer by doing this. In a function that returns a scalar type, the expression's result will automatically be cast into the function's return type as described for assignments. If no message text is specified, the default is to use the condition name or SQLSTATE as message text. Before PostgreSQL 9.1, RAISE without parameters was interpreted as re-throwing the error from the block containing the active exception handler.

Stored Procedure: A block for SQL statements combined together under a name and saved in database which can be called on multiple times when needed. There is a second RAISE syntax in which the main argument is the condition name or SQLSTATE to be reported, for example: RAISE division_by_zero; RAISE SQLSTATE '22012'; In this syntax, USING can be used to supply a custom error message, detail, or hint. The LOG and DEBUG levels are generally not reported back to the client under the default client_min_messages and log_min_messages settings.
