You must recompile procedures using CRC-based deployment for the same schema changes that change a time stamp, except for index changes. (You can add, modify, and change indexes without affecting the CRC of the table so you do not need to recompile.) In addition to the schema changes listed in Database changes that affect time stamps , you must recompile procedures that reference a database table in which you have made the following changes to a field:

The case sensitivity

The following table lists all the metaschema fields involved in database CRC calculation.
