Use Variables in the sql connectionstring

Hi there,

I'm using 2 environments and 2 databases:
1 to create the testcases and 1 to execute them

I want to check the results with DBTables Custom queries (SSMS) and I have i.e. next connectionstring:


How CAN I make this string Variable ?
When I login at the ALPHA-environment  I want in the string ALPHA and server01

When I login at the BETA-environment I want in the string BETA and server02

    It's not possible within that dialog. However you can use ADO Object and create your own connection string using variables e.g.

    function ADOExample()
        var AConnection = ADO.CreateConnection();
        var dbServer = "Server1";
        var dbName = "ALPHA";
        AConnection.ConnectionString = "Provider=MSOLEDBSQL19.1; Integrated Security=SSPI; Persist Security Info=False; Initial Catalog=" + dbName + "; Data Source=" + dbServer + "; Use Encryption for Data=False;";
        // Do something

      Hi rraghvani,

      I'm Using Python as script ion my projectsuite, not C#

      We have tried to make an solution with Python, this solution works outside of Testcomplete, but not within testcomplete:

      import pyodbc

      def SqlConnection():

      # Connectiondata SQL Server
      #if ProjectSuite.Variables.SSMS == "ALPHA":
      server = "server01.isodev.loc"
      database = "ALPHA"
      username = "User123"
      password = "*********"

      # Make connection with SQL Server
      connection_string = f"Driver={{SQL Server}};Server={server};Database={database};UID={username};PWD={password}"
      #connection_string = f"Driver={{SQL Server}};Server={server};Database={database};Integrated Security=True"
      #connection = None

      # Initialise variable 'connection' outsite try

      # Make connection with SQL Server
      connection = pyodbc.connect(connection_string)

      # Make query
      query = f"SELECT top 1 CASE ir.message_data_source_id \
      WHEN 100 THEN 'Artikelbericht' \
      WHEN 101 THEN 'Productbericht' \
      WHEN 102 THEN 'Conditiebericht' \
      ELSE 'Onbekend bericht' \
      END AS [Berichtsoort] \
      FROM import_resource ir \
      WHERE ir.message_type_id = '1'"

      # Run query
      cursor = connection.cursor()
      result = cursor.fetchone()

      if result:
      berichtsoort = result[0]
      print("Berichtsoort:", berichtsoort)
      # Change Project.Variables.Case
      #Project.Variables.Case = berichtsoort
      #Project.Variables.Case = "No result"
      print("No result")
      except Exception as e:
      print("Error making connection or running query", str(e))
      if connection:
      connection.close() # Close connection

      # Call function to make sql connnection

    I have been able to make an ADO connection with the SQL server; but I'm not able to use SQL statements when I use your solution; is this possible or isn't it possible to use SQL statements ?

    I have not provided any SQL statements, as I don't know your database structure.


    If you read the documentation on ADO Object, which I provided, it has example code. Which you can use to query your database.
