是否可以模拟以下MySQL查询:

SELECT * FROM `tbl` ORDER BY `date` DESC LIMIT X, 10

(X是参数)

在MS Access？

我有以下查询,适用于MySQL:

DELETE `test1`, `test2`, `test3`, `test4` FROM
`test1` LEFT JOIN `test2` ON test2.qid = test1.id
LEFT JOIN test3 ON test3.tid = test2.id
LEFT JOIN test4.qid = test1.id
WHERE test1.id = {0}

但它不适用于MS Access.我试图在LEFT JOIN它周围添加括号,但它在FROM子句中给出了语法错误.那么这个查询应该怎样才能在MS Access中工作？

看一下下面的例子:

public void inc(int num) {
   num++;
}

int a = 5;
inc(a);

在这种情况下,inc不会增加a变量本身.它没有指向内存中的相同位置.为了改变a,我将不得不使用ref.

但是,在这个例子中

public static void ExportSelectedRow(GridView gridView, object toObject, int skipCols)
{
    GridViewRow gridViewRow = gridView.SelectedRow;

    if (toObject is DataTable)
    {
        DataTable returnDt = (DataTable)toObject;
        GridViewColsToDatatable(gridView, returnDt, skipCols);
        DataRow dr = returnDt.NewRow();
        for (int i = skipCols; i < gridViewRow.Cells.Count; i++)
            dr[i - skipCols] = gridViewRow.Cells[i].Text;
        returnDt.Rows.Add(dr);
    }

}

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) {
    DataTable dt = …
