Query executes faster in grid mode than

Hello,everyone!!

There is a query which when executed in the grid mode(ctrl+d) takes approx 0.02 seconds(about 21,000
rows) But when I execute in the text mode, it takes about 0.40 seconds!!
Why is this difference?
Also, when the recordsfrom this table are read from a VB application, they are equally slow (as in the text mode!)
Why is it so slow on the text mode & relatively faster in the grid mode?
Has anyone got any idea on ‘Firehose’ style cursor ?(which may speedup access of data in the VB application)

Rgds,
Adie
