Features not supported for remote data

The following SQL Anywhere features are not supported on remote data:

  • ALTER TABLE statement against remote tables.
  • Triggers defined on proxy tables.
  • SQL Remote.
  • Foreign keys that refer to remote tables.
  • Positioned UPDATE and DELETE statements.
  • UPDATE and DELETE statements requiring an intermediate temporary table.
  • Backward scrolling on cursors opened against remote data. Fetch statements must be NEXT or RELATIVE 1.
  • If a column on a remote table has a name that is a keyword on the remote server, you cannot access data in that column. You can execute a CREATE EXISTING TABLE statement, and import the definition but you cannot select that column.
  • Calls to functions that contain an expression that references a proxy table.
