資料視窗小結
資料視窗進行刪除資料時：

int zgxx_id=integer(sle_3.text)
PREPARE SQLSA
        FROM "DELETE FROM ZGXX WHERE id=?";
        EXECUTE SQLSA USING :zg_id2;
        messagebox("提示","刪除完畢!")

應用場景：主要注意分號的使用不加上會報錯誤

int s,zgxx_id,zg_id2
zgxx_id=integer(sle_3.text)
s=dw_1.getrow()
zg_id2=dw_1.getitemNumber(s,"id"
 
)
st_4.text="當前資料：(現有"+string(dw_1.rowcount())+"條)"
if zgxx_id<>0 then
    if messagebox("刪除","是否真要刪除工號為"+string(zgxx_id)+"的資料",Question!,YesNo!,2)=1 then
        PREPARE SQLSA
        FROM "DELETE FROM ZGXX WHERE id=?";
        EXECUTE SQLSA USING :zgxx_id;
        messagebox("提示","刪除完畢!")
    end
 
 if
ELSE
 if s>0 then
    //如果有資料
    //讓使用者確定是否真要刪除資料
    if  messagebox("刪除","是否真要刪除姓名為"+dw_1.getitemstring(s,"xm")+"資料",Question!,YesNo!,2)=1 then
        //dw_1.deleterow(s)
        PREPARE SQLSA
        FROM "DELETE FROM ZGXX WHERE id=?";
        EXECUTE SQLSA USING :zg_id2;
        messagebox("提示"
 
,"刪除完畢!")
    end if
else 
    Beep(1)
    MessageBox("提示","請選擇要刪除的資料")
end if
END IF
