用下面语句更新时间时，当用select查询到jhx表中的记录只有一条时，执行成功，有多条记录时则失败。为什么？
zhjdh=ALLTRIM(thisform.text10.value)
lsj=DATETIME()
=SQLSETPROP(nHandle,"Transactions",2) &&开始人工事务处理
spkjhx="UPDATE spk set spk.时间=?lsj where spk.编号= "+;
"(select jhx.编号 from jhx where jhx.单号=?zhjdh group by jhx.编号)"
sqlspkjhx=Sqlexec(nHandle,spkjhx) &&&修改最后补货
IF sqlspkjhx=1
=SQLCOMMIT(nHandle) &&成功则事务交付
messagebox('成功！',0+48,'提示:')
ELSE
=SQLROLLBACK(nHandle) &&失败则事务回滚
=MESSAGEBOX("失败，请重新执行！",0+16,"提示")
ENDIF
=SQLSETPROP(nHandle,"Transactions",1) &&结束人工事务处理

spkjhx="UPDATE spk set spk.时间=?lsj where spk.编号= "+;
"(select jhx.编号 from jhx where jhx.单号=?zhjdh group by jhx.编号)"
--------------------------------------------------------------------
多条记录用 in 试试
spkjhx="UPDATE spk set spk.时间=?lsj where spk.编号 in "+;
"(select jhx.编号 from jhx where jhx.单号=?zhjdh group by jhx.编号)"
