You could take a look on EXECUTE command in plpgsql...

Depends on concrete problem but should be very careful with dynamic SQL
because of SQL injection potential risk...
Kind Regards,

Subject: [SQL] Call function with dynamic schema name
Hi to everyone,
I would like to use in my function (plpgsql or sql) dynamic schema name to
execute query or to call other functions.

For exemple in oracle is possible to excute query in this manner:


SELECT * FROM &&SCHEMA_NAME..TABLE_NAME;

Where I think &&SCHEMA_NAME. is a sessione variable.

I found tath I can use dynamic SQL like this:

execute 'select * from ' || schema_name || '.table_name';


However, I would like to know if exist any other system to use dynamic
schema name more similiar to Oracle. Another pl language is also ok.


Thank you very much.


Alessio
