Query Task "Where" syntax

I would like to use an "AND" type of function in the Query Task  "Where" field to combine first and last name fields.  Assuming I have field names of "LAST_NAME" and "FIRST_NAME", if I were doing this with a SQL Server command it would be something like:

WHERE (LAST_NAME = 'Smith') AND (FIRST_NAME = 'John')

In the case of the workflow, I have variables for the first and last names, and I can get them to work individually by using a syntax in the form of:

"LAST_NAME = '" + lastName.ToString() + "'"  

"FIRST_NAME = '" + firstName.ToString() + "'"

Using the work "AND" isn't allowed.  I can enter a command using "+" or "&", but when the workflow gets to the Query Task it fails.  For example:  "LAST_NAME = '" + lastName.ToString() + "'" & "FIRST_NAME = '" + firstName.ToString() + "'"

Is it possible to use a Where clause in work flow that would duplicate what I can do in SQL?

  I think what you want is:

  "LAST_NAME = ('" + lastName.ToString() + "') AND FIRST_NAME = ("' + firstName.ToString() + "')"

  In the end, this is all a sting representing the where clause.

  Cheers,

  Chris.

  Thanks Chris.  Small typo in your suggestion (quote and single quote nesting) but this string worked:

  "LAST_NAME = ('" + lastName.ToString() + "') AND FIRST_NAME = ('" + firstName.ToString() + "')"

  Hi Steven,

  Good to see you got it work!

  I have a question regarding to query non-spatial database tables.

  What is the Query Task Url value if I were to query a MS SQL database table? Were you querying a non-spatial database?

  Thanks!!

  Alex

  The query task acess a ArcGIS Server Map Server service endpoint and communicates using REST. That is why the Activity is located in the ArcGIS server section - it is the ArcGIS Server service that translates this query into a SQL statement which it fires against the geodatabase. 

  You can't use the activity to query directly on a SQL database neither a non-ArcGIS Server services.
