Validate database values

In this use case, a test executes an action that modifies a database. The goal of this use case is to validate that the resulting values in the database are correct.

The following table shows a typical flow for a Web Services of the script. You can use a similar validation for other protocols.

Step	API function
Connect to database	lr_db_connect (in vuser_init section)
Web Service call	web_service_call
Execute an SQL query	lr_db_executeSQLStatement
Retrieve and save the data	lr_db_getvalue to <param_name>
Check the data	lr_checkpoint
Disconnect from database	lr_db_disconnect (in vuser_end section)

For more information, see the Function Reference.

The following example illustrates this process of checking the data:

Action()
{
/* A Web Service call that modifies a database on the back end. */
    web_service_call( "StepName=addAddr_102",
        "SOAPMethod=Axis2AddrBookService|Axis2AddrBookPort|addAddr",
        "ResponseParam=response",
        "Service=Axis2AddrBookService",
        "ExpectedResponse=SoapResult",
        "Snapshot=t1227169681.inf",
        BEGIN_ARGUMENTS,
        "xml:arg0="
            "<arg0>"
                "<name>{Customers}</name>"
                "<city>{City}</city>"
            "</arg0>",
        END_ARGUMENTS,
        LAST);
/* Query the database by the customer name that was modified by the Web Service*/
    lr_db_executeSQLStatement("StepName=MyStep", 
        "ConnectionName=MyConnection", 
        "SQLQuery=SELECT * FROM Addresses WHERE name = '{Customers}' ", 
        "DatasetName=ds1", 
        LAST);
/* Get the values retrieved by the database query. */
    lr_db_getvalue("StepName=MyStep", 
        "DatasetName=ds1", 
        "Column=Name", 
        "Row=current", 
        "OutParam=CustomerName", 
        LAST);
/* Compare the actual value with the expected value stored in the database. */
    lr_checkpoint("StepName=validateCustomer", 
        "ActualValue={Customers}", 
        "ExpectedValue={CustomerName}", 
        "Compare=Equals", 
        "StopOnValidationError=false", 
        LAST);
return 0;
