Applies To
The StrComp function can be used in the following versions of Microsoft Access:
- Access 2019, Access 2016, Access 2013, Access 2010, Access 2007, Access 2003, Access XP, Access 2000
Example
Let's look at how to use the StrComp function in MS Access:
StrComp ("TechOnTheNet.com", "TechOnTheNet.com") Result: 0 StrComp ("TechOnTheNet.com", "Abc") Result: 1 StrComp ("TechOnTheNet.com", "Xyz") Result: -1 StrComp ("TechOnTheNet.com", NULL) Result: NULL
Example in VBA Code
The StrComp function can be used in VBA code in Microsoft Access.
For example:
Dim LResult As Integer LResult = StrComp ("TechOnTheNet.com", "TechOnTheNet.com")
In this example, the variable called LResult would now contain the value 0 since both string values are equal.
Example in SQL/Queries
You can also use the StrComp function in a query in Microsoft Access.
For example:
In this query, we have used the StrComp function as follows:
Expr1: StrComp([website_name],"TechOnTheNet.com")
This query will compare the website_name field to the string "TechOnTheNet.com" and display the results in a column called Expr1. You can replace Expr1 with a column name that is more meaningful.
For example:
Comparison: StrComp([website_name],"TechOnTheNet.com")
The results would now be displayed in a column called Comparison.
