i want to create table if that doesn’t, i tried below code:
create or replace function create_table() returns void as $ $ begin if not exists(select * from pg_tables where schemaname = 'Public' and tablename = 'test') then create table test ( the_id int not null, name text ); end if; end; $ $ language 'plpgsql';
While executing this procedure first time:
table gets created but when I execute it again I get the below error:
ERROR: relation "test" already exists CONTEXT: SQL statement "create table test ( the_id int not null, name text )" PL/pgSQL function create_table() line 8 at SQL statement ********** Error ********** ERROR: relation "test" already exists SQL state: 42P07 Context: SQL statement "create table test ( the_id int not null, name text )" PL/pgSQL function create_table() line 8 at SQL statement
How to achieve this, and also I want to call this procedure from Informatica pre-sql target session property so i want to call procedure with table name as parameter.
