Identity Columns in TDM

Identity Columns in TDM

Read the following information before you perform TDM operations on identity columns:
  • You cannot move data from a source DBO schema to a target non-DBO schema on a Sybase database if the data contains an identity column and indexes.
  • If you enable the auto identity option in the database and there are no primary keys or unique keys in a table, Sybase adds the SYB_IDENTITY_COL column. You must mark the column as restricted. A workflow fails if you do not mark the SYB_IDENTITY_COL column as restricted.
  • To disable an identity column on a Microsoft SQL Server database, the database user must have execute permission on sp_help.
