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

  • READTEXT, WRITETEXT, and TEXTPTR functions

  • 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

  • calls to functions that contain an expression that references a proxy table

  • 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.
