drop index syntax

Hello,

I was trying to figure out the drop index syntax for your driver

create table tst (val varchar(50) default null)
create index tstidx on tst (val)

This fails with a parse error:
drop index tstidx

This fails with another error
drop index tstidx on tst


What is the correct syntax?

Thanks,
Rob

DROP INDEX ALL of "tst.idx" ON tst

The index is called tstidx, not idx.
Both of the following fail with a nullpointer:


DROP INDEX ALL of "tst.tstidx" ON tst

DROP INDEX ALL of "tstidx" ON tst

Error: java.sql.SQLException: java.lang.NullPointerException

Try
DROP INDEX ALL of "tstidx" ON tst
or
DROP INDEX ALL of "tstidx.idx" ON tst

The latest package will mask that NullPointerException.
