Check Before Insert

Hi ALL ,

I have 2 tables . I need to write an insert script that should contain the logic of checking if the records are present in the destination table and then perform the insert accordingly .

so 2 tables

Source

Destination

Like in this case Source contains 4 records and Destination 2 so before inserting i wish that it should check for both type and Name if those records are not present then insert so ideally in this case insert for

Should be performed . Please provide the insert script so as per        that i can modify my actual case.

Thanks
