MODIFY command
- Index space copies are registered in the SYSCOPY table (COPY YES indexes) or in the BMCXCOPY table (all other indexes). Only full copies are allowed for indexes so many semantic rules do not apply to indexes.
- You cannot use MODIFY to delete a primary copy without deleting its backup.
In a column condition list, you can specify a column only once. If you specify a column more than once, an error message and return code of 8 is issued. If you need multiple conditions on the same column, such as in a WHERE clause, code a second WHERE clause. The WHERE clauses are interpreted as if the word or were between them to form a complex condition.
The preceding example is logically the same as START_RBA < X'1000' OR START_RBA > X'3000'. A row from SYSCOPY or BMCXCOPY is selected if it satisfies any of the WHERE clauses for the subcommand.
