Problem with select statement

In the following code, I am trying to find a record in my Operators
table based on the field ID. I have a record with ID = John (cap J).
The code below returns this record even thoug I did the select on john
with small j. What am I doing wrong?

(Note: this function returns the variable dTable and boolean result if
a record was found, hence the myDT.copy etc.)

TIA,
John (wiht Cap J LOL)

strSQL = "SELECT * FROM Operators WHERE ID = 'john'"
Dim da As New DbDataAdapter = OledDbDataAdapter(strSQL,
"Microsoft.Jet.OLEDB.4.0;user ID=Admin;Data
Source=C:\TestData\Marymonte.mdb")

Dim myDS as New DataSet
Dim myDT as New DataTable

da.Fill(myDS)
myDT = myDS.Tables(0)
if myDT.Rows.Count > 0 then
dTable = myDT.copy
return True
end if
 
Hi John

Nothing is wrong about your code. Access DB is not case
sensitive.

Hi Elton,
Wow, thanks. I thought I was going crazy. And all these years using
Access I did not realize that. Is it documented somewhere?

Thanks again,
John
 
Thanks Paul. I used the StrComp to solve the problem. Is this also
compatible with SQL Server should my underlying database change?

Transact SQL doesn't support this function so you would have to remove it from your SQL statements
or Access QueryDefs when migrating to another database type.

Thanks Paul.
I have changed my code to use a normal Select and then compare the
results for case sensitivyt...

SELECT * FROM myTable WHERE ID = 'John'

then compare the result john to John and determine it was wrong.

I do not understand why, if the data stored is case sensitive, the
query would not be. From what I have read, this seems to be a
convention that has been around a while. But it makes no sense to
me...I query for what I want...if I wanted lower case, I would have
quereid for it...oh well,

With SQL Server or Access? I think we've already established that Access does not support case
sensitive based criteria.
