It has been an interesting two days trying to attempt quizzes. Thank you Tom for your tireless responses, really appreciate.

The question is what are called data buffers and how many types of data buffers (what are they) are used in progress. What you explained looks as though they all point to record buffer which we are referencing using explicit buffer names if necessary. Hence, as an answer to the question, I...

Qn 26: What is the difference between searching and filtering when using a database table? Ans: Search – searches for the records in the table – usually returns logical answer.

I will ignore Qn 22 as it is another include file. Qn 23 is simple. Qns 24: We have the code below. What happens when the <condition> becomes true? What block is left and how can we force to leave the other block? For EACH table1: For EACH table2: /*Do something…*/ IF condition THEN LEAVE...

Qn 21: What are the ways to pass a temp-table as a parameter? Ans: Use TABLE FOR?
