用adodb驱动查询mssql数据。如果参数带有大括号。就会显示错误： ServeSrs sql db.Prepare error发生意外。 (语法错误或违反访问规则) 代码如下：

    db, err0 := sql.Open("adodb", cfg.Cfg["mssql"])
    if err0 != nil {
        log.Println("ServeSrs sql open error")
    } else {
        defer db.Close()
        stmt1, err0 := db.Prepare(`
            select top ? *
            from (select a.[Id], a.[CreateDate],a.[PublisherId],a.[NickName],a.[FileSize],a.[Followed],
            a.[Readed],a.[FilePath], b.[STitle],row_number() over(order by a.CreateDate desc) as rownumber
            from [hds12204021_db].[dbo].[Web2019_historylist] a, [hds12204021_db].[dbo].[Web2019_roomlist] b
            where a.roomid = ? and a.Deleted = 0 and a.roomid=b.id ) temp_row
            where rownumber>((?-1)*?)
        `)
        if err0 != nil {
            log.Println("ServeSrs sql db.Prepare error" + err0.Error())
        } else {
            defer stmt1.Close()
            rows, err := stmt1.Query(pagesize, roomid, pageid, pagesize)

然后我们把Prepare格式化的字符串，换个方式搞下：

    db, err0 := sql.Open("adodb", cfg.Cfg["mssql"])
    if err0 != nil {
        log.Println("ServeSrs sql open error")
    } else {
        defer db.Close()
        sqlstr := `
            select top ` + pagesize + ` *
            from (select a.[Id], a.[CreateDate],a.[PublisherId],a.[NickName],a.[FileSize],a.[Followed],
            a.[Readed],a.[FilePath], b.[STitle],row_number() over(order by a.CreateDate desc) as rownumber
            from [hds12204021_db].[dbo].[Web2019_historylist] a, [hds12204021_db].[dbo].[Web2019_roomlist] b
            where a.roomid = '` + roomid + `' and a.Deleted = 0 and a.roomid=b.id ) temp_row
            where rownumber>((?-1)*?)
        `
        //log.Println(sqlstr)
        stmt1, err0 := db.Prepare(sqlstr)
        if err0 != nil {
            log.Println("ServeSrs sql db.Prepare error" + err0.Error())
        } else {
            defer stmt1.Close()
            rows, err := stmt1.Query(pageid, pagesize)

OK,先自己拼接字符串，再喂给mssql 的adodb驱动就行了。。这坑太奇葩。。
