ISNOTNULL function
Determine if a string is not null (contains 1 or more characters). |
|
Syntax |
ResultVar& = ISNOTNULL(StrgExpr) |
Remarks |
The StrgExpr is examined to determine if it is null, or if it contains one or more characters. The value true (-1) is returned if the StrgExpr contains characters, or false (0) if it is null (zero-length). The complementary function is ISNULL. |
