Sintaxis

Parts

• object

Prototype (C/C++)

HRESULT EnumLocks(
LPSQLDMOQUERYRESULTS* ppResults,
long Who = -1);

Returns

A QueryResults object that contains one result set defined by these columns.

Column	Data type	Description
dbname	nvarchar(129)	Name of the database in which the locked resource is defined.
indexname	nvarchar(129)	If applicable, the name of the index against which the lock is applied.
locktype	nvarchar(36)	A text description of a locking mode. For more information about interpreting values, see the description of the system table syslockinfo column req_mode.
