lQuery.ConnectionString 的值不正确应该少了DATABASEURL

sxl841117

lQuery := TQuery.Create(nil);
  lstr := FuncBroker.Func.Parameters;
jsdialogs.ConfirmBox(lstr,'123',2); <-----我尝试了在这里加了句 lstr的值是可以取到的
  try
  ..........

sxl841117

DATABASEURL 应该是到数据库的URL吧？

shangxy

lQuery.ConnectionString :='DATABASEURL=Biz:\HGOPERATION\HGOPERATIONDB.DATABASE'

sxl841117

Biz:\HGOPERATION\HGOPERATIONDB.DATABASE\RJXGJLB.Table

Biz:\HGOPERATION\HGOPERATIONDB.DATABASE

哪个？
