TestComplete samples (both built-in and additional) are located in the <Users>\Public\Public Documents\TestComplete 14 Samples folder.

Some file managers display the Public Documents folder as Documents.

You can connect to databases using the ADO DB functionality included in Microsoft Windows. You can instantiate connections, record sets and commands as COM objects and then use their methods and properties in scripts. To specify values of properties or method parameters that accept constants, you may need to use the integer equivalents of the constants, since the constants may be undefined in TestComplete.

The following example demonstrates how you can instantiate Microsoft ADO DB objects in your scripts and use them to iterate through table records.

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.

TestComplete 32-bit executable is located in the <TestComplete>\Bin folder.
