Re-compiling PL/SQL script

Sometimes when we alter tables all procedure which calling those table will be invalid. If relation is just a few number, its easy to recompile those procedure/package by hit compile button in GUI such as TOAD or SQL Detective.

But if it has many relation into procedure, package or function. Its more simpler to recompile all invalid procedure by running this command :


To find all invalid object we may use :
select ‘ALTER ‘ || OBJECT_TYPE || ‘ ‘ ||OWNER || ‘.’ || OBJECT_NAME || ‘ COMPILE;’
from dba_objects
where status = ‘INVALID’
and object_type in (‘PACKAGE’,’FUNCTION’,’PROCEDURE’)
and owner = [schema_name]

and then execute command by EXECUTE_IMMEDIATE
