请大家帮忙,错误提示:Invalid BLOB handle in record buffer.(在线)

johnsonrao 2002-06-12 02:05:57
SQL Server 7.0, 操作表主键为自动增长 ID。
使用 Query + UpdateSQL + DataSource 结构
在 DBGrid 中直接进行数据操作时出现错误提示:
Invalid BLOB handle in record buffer.
经测试在按顺序修改时无错误,在顺序混乱时修改数据时就可能出错。
请问各位高手,为什么?应该怎样解决?

本人剛才也出現類似問題,只要更改BDE配置,
將BLOB SIZE和BLOBs to cache增大,
BLOB SIZE:
Default Value: 32
Range : >32 and <1000

BLOBs to cache:
Default Value: 64
Range : >64 and < 65536

要是BDE中BLOB SIZE的设置为32的话,长度超过255的记录不能太多,好象是64条,不然就会有这个错误

要還是不行,就減少Query中返回的紀錄的數量.

你的BDE的BLOB SIZE設置的太小,改大一點吧.

由于各种外部原因,必须在DBGrid中完成。

不行啊,表结构定义是用户自定义方式,并且字段很多,使用TDBEdit界面生成操作太复杂,接受不了。
