Sybase There are some features of the Adaptive Server Enterprise DECLARE CURSOR statement that are not supported in Adaptive Server Anywhere.
Adaptive Server Enterprise supports cursors opened for update of a list of columns from the tables specified in the select-statement. This is not supported in Adaptive Server Anywhere.
In the Watcom-SQL dialect, a DECLARE CURSOR statement in a procedure, trigger, or batch must immediately follow the BEGIN keyword. In the Transact-SQL dialect, there is no such restriction.
In Adaptive Server Enterprise, when a cursor is declared in a procedure, trigger, or batch, it exists for the duration of the procedure, trigger, or batch. In Adaptive Server Anywhere, if a cursor is declared inside a compound statement, it exists only for the duration of that compound statement (whether it is declared in a Watcom-SQL or Transact-SQL compound statement).
CURSOR type (UNIQUE, NO SCROLL, and so on) and CURSOR FOR statement-name are not supported in Adaptive Server Anywhere.
