Syntax
GET-NEXT ( NO-LOCK | SHARE-LOCK [ , NO-WAIT ]
| EXCLUSIVE-LOCK [ , NO-WAIT ] )
|
- NO-LOCK
- Specifies that no lock is applied to the record. This applies
to all buffers in a join. Unless explicitly specified otherwise,
this is the default lock type for this method.
- SHARE-LOCK
- Specifies that the record is share locked. This applies to all
buffers in a join.
- EXCLUSIVE-LOCK
- Specifies that the record is exclusively locked. This applies
to all buffers in a join.
- NO-WAIT
- Specifies that the method returns immediately if the record
cannot be accessed because it is locked by another user. If you
do not use the NO-WAIT option, the method waits until the record
can be accessed. This applies to all buffers in a join. If you specify
NO-WAIT and the record is locked by another user, the record is
returned to you with NO-LOCK and the LOCKED function returns TRUE
for the record.
GET-NEXT() returns TRUE
if the next record in the query is found. If the query is not open
or the next record cannot be found (query is empty or the query
result list pointer is on the last row), the method returns FALSE.
If the query object handle is invalid, the method returns the Unknown value (?).
