SQL Statements in Invoke

Question

i have an invoke process to an external MYSQL DB which retreives prefills values for me in the form.
but this invoke works with constants or directly entering the value into the sql statement as shown.
SELECT street FROM users WHERE city ='ABC';
everything works fine here... did trace and even my form fields get populated.
but i need to pass the value instead of ABC
i need to pass the value of 'city' from an other field in the form.
Thanks

Yes, if you intend to connect to MySQL, you'll need that jar in place.
A sample code that I run is below:
  <RuleArgument name='sql'/>
  <invoke name='queryList' class='com.waveset.util.JdbcUtil'>
    <map>
      <s>type</s>
      <s>oracle</s>
      <s>driverClass</s>
      <s>com.mysql.jdbc.Driver</s>
      <s>driverPrefix</s>
      <s>java:oracle:thin</s>
      <s>url</s>
      <s>jdbc:mysql://localhost:3306/database_table_name</s>
      <s>host</s>
      <s>localhost</s>
      <s>port</s>
      <s>3306</s>
      <s>database</s>
      <s>database_table_name</s>
      <s>user</s>
      <s>waveset</s>
      <s>password</s>
      <s>waveset</s>
      <s>sql</s>
      <ref>sql</ref>
    </map>
  </invoke>I could never understand why I set references to ORACLE for a MYSQL connection (like type, etc), but I remember having some trouble when I used any other values. This was a while ago. .The above code works great, assuming the connection parameters are correct, and the user has been authorized to connect to the DB.
BTW, if a URL has been provided, some of the information below it is redundant.
