I know that Visual Basic is not case-sensitive, but it preserves the capitalization where the name is declared. I have a need to capture only lower case characters in a single field. I would think this coule be accomplished with a siple query, however, I cannot find the correct syntax. Can anyone help? [sig][/sig]

LCase Function
Syntax
LCase(string)
The required string argument is any valid string expression. If string contains Null, Null is returned.
Remarks
Only uppercase letters are converted to lowercase; all lowercase letters and nonletter characters remain unchanged. [sig]<p>Bill Paton<br><a href=mailto:william.paton@ubsw.com>william.paton@ubsw.com</a><br><a href= Check out my website ![/sig]

Thank you for the reply, however, I am not looking to convert text. I am trying to select off records from a table based on one field that contains a single upper and lower case character (i.e. A,a,B,b). The results of the sucessful query will only contain the lower case character. I can't find a function that will only select the lower case characters. Any assistance would be appreciated. Thank you.

There is no easy solution to this but you could use the ASC function :
SELECT Asc(YourTableName.TheField) AS ASCvalue, YourTableName.TheField
FROM YourTableName
WHERE (Asc(YourTableName.TheField)=97);
This will return all the "a"
What you could do is create a table of ASCII numbers for the lower case letters and join them.
Create a table ( Table1 ) with one field - Character - and populate it with you lower case chacters.
Use this SQL to create th ASCII table
SELECT Asc([Table1.Character]) AS ASCvalue, Table1.Character
INTO tblASCII FROM Table1;
Jon SQL will be:
SELECT YourTableName.TheField
FROM YourTableName INNER JOIN tblASCII ON Asc(YourTableName.TheField) = tblASCII.ASCvalue;
Hope this helps, Good Luck [sig]<p>Bill Paton<br><a href=mailto:william.paton@ubsw.com>william.paton@ubsw.com</a><br><a href= Check out my website ![/sig]
