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.

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.
