Multiple sql delete

hello guys,

Looking to delete lots of test data out of my database. I have written a basic SQL query but it is not running? Syntax error?

DELETE * FROM ABST
DELETE * FROM NAVT
DELETE * FROM PositionT
DELETE * FROM PricingT
DELETE * FROM XoverT;

I dont want to delete the table or lose its struture, just wanted to emtpy the data. it works if i write a query with one line, but was hoping i could do this all in one go?
