Thanks Dave,
I agree with you. The function can catch error and return some value but PL/SQL only can return integer an PGSQL could return empty string or integer.
When I call to db_exec_plsql on oracle and get error should be catch inside and return some code (0,-1,...). One problem is PostgreSQL could return "".
If i call to the tcl function I can receive one integer or empty string for PostgreSQL, and integer (or error) for Oracle and no is the same behavior Ej
If { [fs::get_root_folder -package_id 123] eq "" } {
#package_id isn't exist but it work for PG and not for Oracle.
}
Maybe, It's posible to normalize calls to Oracle PL/SQL and return empty string if it get errors.
I hope, you can understand my special english 😟.
