I was able to use this query
Code:
SELECT tblYourTableName.ProductCode
FROM tblYourTableName
WHERE (((InStr([ProductCode],"#"))>0));
but thought there must be a better way.
Since the hash mark is a delimiter in Access, I found adding brackets tells Access to search for the hash as a text character. (This will work for any special character)
Code:
SELECT tblYourTableName.ProductCode
FROM tblYourTableName
WHERE tblYourTableName.ProductCode Like "*[#]";
Change "tblYourTableName" to the name of your table.......
