Opening a cursor variable v14
Once you declare a cursor variable, you must open it with an associated
SELECT command. The
OPEN FOR statement specifies the
SELECT command to use to create the result set:
name is the identifier of a previously declared cursor variable.
query is a
SELECT command that determines the result set when the statement is executed.
The value of the cursor variable after the
OPEN FOR statement is executed identifies the result set.
This example shows a result set that's a list of employee numbers and names from a selected department. You can use a variable or parameter in the
SELECT command anywhere an expression can normally appear. In this case, a parameter is used in the equality test for department number.
