How to get all the procedure name and definition in a given schema in Redshift?

问题

When using Redshift, I would like to get the names of all the procedure that were created in a schema, along with their definition.

I know you can use the SHOW PROCEDURE command to get the definition but that requires to have the procedure name.

In SVV_TABLE there is only information regarding tables and view but not procedure.

So if anyone knows how to get that ?

回答1:

Redshift doesn't have a system view for that yet but you can use tbe PG_PROC table and join it with pg_namespace to filter on schema name.

    select proname, proargnames, prosrc
    from PG_PROC
    join pg_namespace on pg_namespace.oid = pg_proc.pronamespace
    where nspname = 'your_schema_name' and procsecdef = true;

The procsecdef = true is to get only stored procedure definition otherwise you also get python UDF.
