我想根据以下链接进行自定义分页：

但我的存储过程在informix中：

所以我搜索等价物row_number()我找到了这个解决方案

但是当我在我的程序中使用它时，我收到以下错误：

SQL 错误 -944 在这种情况下不能使用“first”、“limit”、“skip”！

如何用informix规则重写上一个链接中的存储过程？

我的程序有多个联合是这样的：

create procedure get_inbox_page(p_emp_num smallint, p_task_code smallint, p_main_code smallint default 0, p_year smallint default 0,p_page int)
returning varchar(60) as v_page_view, varchar(60) as v_task_name, smallint as v_task_code, varchar(60) as v_sp_name, varchar(60) as v_db_name, varchar(60) as v_column_key,  smallint as v_trans_serial, 
    DATETIME YEAR TO FRACTION(3) as v_trans_date, varchar(60) as v_trans_desc , varchar(60) as v_emp_name, varchar(60) as v_values_key, smallint as v_old_state_serial, 
    smallint as v_new_state_serial, smallint as v_main_code, smallint as v_year, varchar(60) as v_page_new, smallint as v_task_type, smallint as v_task_status,smallint as v_mail_maincode,smallint as v_mail_year,smallint as v_mail_number,smallint as v_trans_year , smallint as candidate_flag ;

您不能使用FIRST等SKIP，因为集合中的每个SELECT语句UNION都是自包含的。

也许您可以尝试创建一个VIEW封装SELECT ... UNION ... SELECT逻辑，然后将FIRST/SKIP逻辑应用于该逻辑。

尝试这个

;
WITH    tempPagedRecord
          AS ( SELECT   Column1 ,
                        Column2 ,
                        Column3
               FROM     TableName AS e--Your query with union 
               UNION ALL
               SELECT   Column1 ,
                        Column2 ,
                        Column3
               FROM     TableName AS e--Your query with union
             )
    SELECT  * ,
            ROW_NUMBER() OVER ( ORDER BY Column1 ASC ) AS RowNumber--RowNumber over some column
    FROM    tempPagedRecord 
 WHERE RowNumber BETWEEN(@PageIndex -1) * @PageSize + 1 AND(((@PageIndex -1) * @PageSize + 1) + @PageSize) - 1
