SQL - LIKE AND

I hope this is an easy question for someone.  I am using ADO to access some data.  I need to write a SQL statement to narrow that data down.  I can use the LIKE statement successfully for one option, but not multiple.  Here is some code.

'This string will work
strSQL = "Field1 LIKE '%" & txtOption1 & "%'"

'I need something like this to work
strSQL = "Field1 LIKE '%" & txtOption1 & "&' AND Field2 LIKE '%" & txtOption2 & "%' AND Field3 LIKE '%" & txtOption3 & "%'"

Set rsRecordSet = New ADODB.Recordset
With rsRecordSet
    .CursorType = adOpenStatic
    .CursorLocation = adUseClient
    .LockType = adLockPessimistic
    .Source = "SELECT * FROM Table1 WHERE " & strSQL
    .ActiveConnection = connConnection
    .Open
End With

I get the follwoing error when I run it with the SQL statement that has multiple LIKE statements in it.  ( I put "test" in txtOption2)

**  Syntex error (missing operator) in query expression 'AND Field2 LIKE '%test%"  **

Thanks for the help!

try:

strSQL = "Field1 LIKE '%" & replace(txtOption1,"'","''") & "' AND Field2 LIKE '%" & replace(txtOption2,"'","''") & "%' AND Field3 LIKE '%" & replace(txtOption3,"'","''") & "%'"

or

strSQL = "Field1 LIKE '%" & replace(txtOption1,"'","''") & "%' AND Field2 LIKE '%" & replace(txtOption2,"'","''") & "%' AND Field3 LIKE '%" & replace(txtOption3,"'","''") & "%'"

Try this
'-----------------------------------------------
strSQL = "Field1 LIKE '%" & Replace(txtOption1,"'","''") & "%' AND Field2 LIKE '%" & Replace(txtOption2,"'","''") & "%' AND Field3 LIKE '%" & Replace(txtOption3,"'","''")  & "%'"
'------------------------------------------------

u put an extra   &   instead of   %

I understand what you are getting at, but I haven't used any apostraphes in the textboxes so the Replace statement shouldn't change anything.... right?

I tried that and it didn't work.

Any more ideas??

What is in the value of strSQL when you execute the command?  Can you paste it in here so we can have a look?
Just add the line :
Debug.Print "SELECT * FROM Table1 WHERE " & strSQL
when you set the '.Source' to make it appear in the immediate window.

Which database are you using?

There is a very simple way to do this using the "Microsoft Script Control 1.0". All you need to do is create a string which is the expression you want to evaluate and just let the "Microsoft Script Control 1.0" evaluate it.

You can set the 'strExpression' string to any vb expression e.g.: "3 / 4" or "5 * (6 - 1)" etc.


Private Sub Command1_Click()
    Dim dblResult As Double
    Dim strExpression As String
    Dim MyScripControl As Object
    Set MyScripControl = CreateObject("ScriptControl")

    strExpression = "3 / 4"  '<---  You can put any expression you like here

    MyScripControl.Language = "VBScript"
    dblResult = MyScripControl.Eval(strExpression )
    MsgBox dblResult

End Sub

Ok, I made a stupid mistake.  I was using a few IF  statements to create the SQL statement depending on whether data was entered into the textbox or not.  I used the following

strSQL = " AND Field1 LIKE '%" & txtOption1 & "%'"

I quickly figured out after using the debug.print than I needed the following

strSQL = strSQL & " AND Field1 LIKE '%" & txtOption1 & "%'"

I was so unsure of my SQL syntax that I completely forgot a little simple debuging.

Thanks for all the help!!
