Why can't I use the Like Predicate

I'm using ADO to connect to an Access 95 database through a DSN.  The problem is I have SQL statement similar to the following

SELECT * FROM [Table] WHERE [FieldName] Like('*" & FieldValue & "*') ORDER BY [FieldName2]

Now there is nothing wrong with the SQL string because if I go into Access and put this as a query it returns the correct records.  The problem is when I run the following line:

  rs.Open sSQL, "DSN=Town;uid=;pwd=", adOpenForwardOnly, adLockReadOnly

I get this error:

Expression cannot be used with the Like predicate. in query expression '[Owner]  alike('*Name*')'.

Try this, i think it's gonna work !

dim query as string
query = "Mr. Jones"   ' Exemple !
query = "*" & query & "*"
"SELECT * From [Table] " & "WHERE [Field] LIKE " & "'" & query & "' "

Use the same answer as BeerMan gave, but include the asterisks inside the quotes. There's no asterisks in there.

"SELECT * From [Table] " & "WHERE [Field] LIKE " & " ' " & query & " '

The quotes have to be Outside.

They are inside the quotes if you look it say 'query' where query = *Mr.Jones*.

This is what my final SQL Statement evalutes to

SELECT [ID],[Location],[Owner],[Map],[Lot],[Unit] FROM [Town] WHERE  [Owner]  Like '*diesso*' ORDER BY [Owner]

the odd thing is if I run this exact same query in Access it returns one record (which is what it is supposed to do), but doing

rs.open ABOVESQLSTATEMENT, cn, adOpenForwardOnly, adLockReadOnly

where rs is an ADODB.Recordset object and cn is a ADODB.Connection object I get rs.eof evaluting to TRUE.  Now I know the connection to the database is valid because I can run a different SQL Query w/out the like predicate and it returns the way it is suppose to.

I know that when you run a LIKE predicate in Transact-SQL on SQL Server, you have to use the "%" instead of "*" as a wildcard character. Maybe you should try changing your asterisks to percent signs and see if it returns something.
