Ques:- How do you that one record was entered in to a particulartable using winrunner?

Asked In :- bitdefender, perfecto mobile,

Right Answer:
You can use the `db_check` function in WinRunner to verify that a record was entered into a particular table. This function allows you to execute a SQL query to check for the existence of the record in the database. For example:
