expr_1语句该了三个，都不行，郁闷啊

[acen_chen]

ls_err都看一看呀

先锁住更新 SetRedraw(false)
检索完之后再解锁更新 SetRedraw(true)

經測試, 並未發現問題 可以順利運行 string expr_1 string ls_present,ls_syntax,ls_err expr_1="select * from ref_ge_code" ls_present='style(type=grid)' ls_syntax=SQLCA.SyntaxFromSQL(expr_1,ls_present,ls_err) dw_1.Create(ls_syntax, ls_err) dw_1.setTransobject(sqlca) dw_1.retrieve()
