Case Sensitive search with SQL - CodeProject

You have a table of words, some of which appear multiple times. Each instance of these words is spelled using a different combination of upper- and lowercase. Is there any way to create a query that can select records based on case-sensitive criteria?

Access normally performs case-insensitive string comparisons. You can use the Option Compare Binary statement in the declarations section of a module to force VBA to make string comparisons that are case-sensitive within the bounds of that module, but this affects only string comparisons made in a VBA module, not comparisons made by the Jet engine. Thus, even when you run the query from a VBA Option Compare Binary procedure, any comparisons made in the query are case-insensitive.

Fortunately, you can create your own case-sensitive string-comparison function in an Option Compare Binary module and call this function from the query. This solution shows you how to create the VBA function and how to use it to perform case-sensitive searches. Create a query for which you wish to perform a case-sensitive search.

Add all the desired fields in the query grid. Create a computed field in the query grid that references the acbExactMatch function found in basExactMatch. For example, if you wish to compare the Word field with a user-entered parameter, create a field like that shown in Table You can also use a hard-coded string instead of a parameter. We used a parameter in the qryWordCS query, shown in design view in Figure When you execute the query, it will return only exact, case-sensitive matches.

If you run qryWordCS in the Now, open the tblWords table in MDB see Figure When the query executes, it returns all four swordfish records, not the specific version you typed at the prompt.

Now run the qryWordsCS query, entering the same string at the prompt. This solution uses a simple VBA function to perform a string comparison. Because this function resides in a module that contains the Option Compare Binary statement, any string comparisons made using procedures in this module are case-sensitive.

The acbExactMatch function is simple:. This function returns True only when the strings are spelled exactly the same way. This function can compare two strings on a binary basis that is, it compares each character in the strings, taking case into account and returns 0 if the two strings are exact matches.

You can also use this function when creating a recordset in VBA or when using one of the Find methods on an existing recordset. For example, the sample FindString procedure, which can be found in basExactFindSample, finds records using case-sensitive criteria:. With Safari, you learn the way you learn best.
