Create Queries On the Fly

Create Queries On the Fly

Use VB’s string-concatentation operator (&) to incorporate user input into SQL queries at run time. Assume, for example, that cboField is a combo box containing a list of fields in a table, and txtValue is a text box into which the user types a value to search for. Here’s how to create a dynamic query that includes the user’s input:

 sField = cboFieldsValue = txtValueSQL = "SELECT * FROM Table WHERE " & _	sField & " LIKE '" & sValue & "';"

Note that you must surround the search value with quotes if you are searching a text field; no quotes are necessary if the target field contains numeric data./p>
