SQL Server事务日志可能会被填满,这会阻止之后的数据库操作,包括UPDATE, DELETE, INSERT 和CHECKPOINT。 事务日志填满会导致1105错误: Can't allocate space for object syslogs in database dbname because the logsegment is full。 If you ran out of space in syslogs, dump the transaction log。 Otherwise use ALTER DATABASE or sp_extendsegment to increase the size of the segment。
