附件为sqlldr日志中的报错,
在数据库后台跟踪出现如下的lock等待
holder(NPBSPROD_AFFINIUM-146:10842) SQL=SELECT 'X' FROM SYS.LOADER_PART_INFO WHE
RE TNAME = :1 AND OWNER = :2 AND PARTTYPE = 3
waiter(NPBSPROD_AFFINIUM-21:58744) SQL=DELETE FROM NPBSPROD_AFFINIUM.UA_SEGMEMBE
RSHIP WHERE (SegmentID = 191)
在这里SQL=SELECT 'X' FROM SYS.LOADER_PART_INFO WHERE TNAME = :1 AND OWNER = :2 AND PARTTYPE = 3 阻塞了下面的delete语句,想问下各位,这句select的意义是什么?查了文档说的也不清楚, 求各位指教。
