Recompiles

  • I have a inherited a new database that uses a stored procedure to recompile all of the tables in the database and can find no documentation about recompiling tables only stored procedures. I do want this to mark procs for recompile and was told that when you mark a table for recompile that every dependent object is recompiled as well. Is this true and if so where are the docs that talk about this?

  • Right in BOL, look for the sp_recompile TSQL page. Not sure why you would want to do this on any regular basis.

    From Sybase docs:

    An sp_recompile should be issued any time a new index is added or an update statistics. Dropping an index will cause an automatic recompile of all objects that are dependent on the table.

    I'm not completely sure that the same goes for SQL server ( 6.5 - for sure), but probably there is something to look at.

    Also sp_recompile looks for objname only in the current database and recompiles triggers and stored procedures only in the current database. sp_recompile does not affect objects in other databases that depend on the table.

    You cannot use sp_recompile on system tables.

  • I agree with Andy in that I see no reason why you would want to do this as you lose the advantage of stored execution plans unless you are making column name changes or datatype changes. Epol is right if indexes change an sp_recompile should automatically issue. Also if you really are wanting to force a recompile on stored procedures you can always add the WITH RECOMPILE statment to the Procs themselves but this of course will further hurt performance in most cases.
