Description
Use the ADODriver method to create a driver object for a recordset that can be accessed via Microsoft’s ADO DB (the recordset can be a table or result of an SQL query). You can then use this driver to iterate through the recordset, obtain values stored in its fields and use them in your data-driven tests. The names and order of the driver columns coincide with the order and names of the recordset columns.
Declaration
DDT.ADODriver(ConnectionString, TableName)
| ConnectionString | [in] | Required | String | |
| TableName | [in] | Required | String | |
| Result | An ADODriver object |
|||
Applies To
The method is applied to the following object:
Parameters
The method has the following parameters:
ConnectionString
Specifies the connection string used to connect to the database holding the desired recordset.
TableName
Specifies the name of the desired table or a SELECT SQL statement that will be executed to obtain the recordset.
Result Value
An ADODriver object that provides access to data stored in a recordset.
Remarks
The DDT object is available only if the Data-Driven Testing plugin is installed.
For information on working with DDT drivers, see Using DDT Drivers.
For information on specifics and limitations of the ADO DDT driver, see Using Database Tables as Data Storages.
Example
The code below connects to the specified database, retrieves information about the name of the command used by the database's myTable table, posts this name to the test log and then closes the connection to the database.

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. |
