Hi,

I have read that TSQ is used for the data transactions which can happen randomly or sequentially and TDQ is used for the data transactions which can happen only sequentially?

If the above is wrong, please suggest your comments?

And please let me know the main difference between TSQ AND TDQ.

Thanks for your help in advance.

All the information is in the manual. Once you have researched, come back with any questions about things that you are unclear about. Also, you could try putting your topic title into the search bar above. I've just educated myself by doing so.

TDQs are read destructive.. as soon as read occurs on a record, that record will get deleted from TDQ.

Whereas, in TSQ, program can read the records sequentailly (or) randomly. it wont delete records when read happened.
