The following example demonstrates how you can use the ADO Command object in your scripts. The TestProc routine executes a query with parameters and posts query results into the test log.

Notes:

  • This example uses the OrdersDB.mdb file that is part of the additional sample package. To use it, download this package from support.smartbear.com/downloads/testcomplete/samples/ and install it. After the installation is over, you can find the database in the <TestComplete 14 Samples>\Desktop\Checkpoints\XML\DataGridViewSample folder.

  • The syntax of the command’s query depends on the SQL provider you use. For instance, if you work through the Microsoft.Jet.OLEDB.4.0 provider, you can specify parameters by their names. Some other providers may use question marks (?) as parameter placeholders (the first question mark corresponds to the first parameter, the second - to the second and so on). Some providers may support both techniques, or use their own syntax. For more information on the command syntax, see the database provider's documentation.

  • Using the Microsoft.Jet.OLEDB.4.0 provider requires that you run your script in the 32-bit version of TestComplete.
