database checkpoints in keyword tests

Hi Folks,

I am using keyword tests in test complete V 12.3, I record and playback the scripts and also perform database validations by using database checkpoints and also run script routine. For using these two for each and every script I have to give connection to my database manually by entering manually, is there a way out I can connect once to my database for each project I maintain irrespective of the number of keyword tests is contain or is there any other work around we can do for this. I appreciate your thoughts on this.

Thanks for your help in advance.
