It is possible that a procedure remain valid even when the data type of columns of a table on which it is operating change.


This can be achieved by using Anchor declaration i.e. %TYPE and %ROWTYPE while defining reference to such table columns and rows respectively in the procedure.

Yes the package will become invalid and it will be automatically recompiled when it is called (in case it is local object), if it is not local then we have manually recompile it.

Whenever any changes are occur in referenced objects then automatically subprograms are come into invalid. So you need to compile the subprogram for valid status.

Example: By using the below query you can find the status of the subprogram.

select status from user_objects where object_name=&SUBPROGRAM_NAME;

Whenever the column of the data type of a table which is referred by particular procedure is changed then in that case to retain the valid status of procedure we have to recompile the procedure.

If PL/SQL stored SP %type and does not explicity declare a datatype, then it is quite possible that Stored procedure remains valid, even after changing the datatype in the table.

Ex, you have a declaration num TAB.Num%type

If this was NUMBER(11)  earlier, and now it is changed to NUBER(13,2), it does not make the SP invalid.

But yes, during runtime you might face some isues
