"ProductID" is equal to "PRO_XYZ10", the StrComp function will return 0. If "ProductID" is less than "PRO_XYZ10", the StrComp function will return -1. If "ProductID" is greater than "PRO_XYZ10", the StrComp function will return 1. If either "ProductID" or "PRO_XYZ10" is NULL, the StrComp function will return NULL. |
VBA example
Note
Examples that follow demonstrate the use of this function in a Visual Basic for Applications (VBA) module.
This example uses the StrComp function to return the results of a string comparison. If the third argument is 1, a textual comparison is performed; if the third argument is 0 or omitted, a binary comparison is performed.
Dim MyStr1, MyStr2, MyComp
MyStr1 = "ABCD": MyStr2 = "abcd" ' Define variables.
MyComp = StrComp(MyStr1, MyStr2, 1) ' Returns 0.
MyComp = StrComp(MyStr1, MyStr2, 0) ' Returns -1.
MyComp = StrComp(MyStr2, MyStr1) ' Returns 1.
