Case-sensitive SQL Queries with Access Jet Engine

How do I get the VB4 Access Jet Engine to do case-sensitive queries? Eg.

SELECT * FROM someTable WHERE someField = 'i'

Here "someField" is assumed to be a text field, and I would like only 'i' records (and not 'I' records) to be returned. The default behaviour seems to be case-insensitive.

Your problem will be solve now ...

Use the "Like" operator instead "=".
This example returns a list of employees whose names begin with the letters A through D.
 
SELECT * FROM Employees WHERE LastName Like "[A-D]*"

 
The following table shows how you can use Like to test expressions for different patterns.
 
Kind of match              Pattern       Match (returns True)      

Multiple characters      "a*a"              "aa", "aBa", "aBBBa"      
                      "*ab*"              "abc", "AABB", "Xab"      

Special character      "a[*]a"              "a*a"      
Multiple characters      "ab*"              "abcdefg", "abc"      
Single character      "a?a"              "aaa", "a3a", "aBa"      
Single digit              "a#a"              "a0a", "a1a", "a2a"      
Range of characters      "[a-z]"              "f", "p", "j"      
Outside a range              "[!a-z]"      "9", "&", "%"      
Not a digit              "[!0-9]"      "A", "a", "&", "~"      
Combined              "a[!b-m]#"      "An9", "az0", "a99"      


Good Luck...

Sorry seumas but the table is not well, but you can get this table, on VB help.

Hi,

I tried out this solution and it didn't work. The "Like" operator works fine in plain VB code, but in an SQL statement it is still case-insensitive. I got a solution from the newsgroup however:

SELECT * FROM someTable
WHERE someField = 'i'
AND StrComp([someField],'i',0) = 0 ;
