通用的SQL数据分页存储过程

CREATE PROCEDURE spGetPageOfRecords
  @pageSize int = 20,                                      -- 分页大小
  @currentPage int ,                                  -- 第几页
  @columns varchar(1000) = '*',                        -- 需要得到的字段
  @tableName varchar(100),                               -- 需要查询的表    
  @condition varchar(1000) = '',                      -- 查询条件, 不用加where关键字
  @ascColumn varchar(100) = '',                       -- 排序的字段名 (即 order by column asc/desc)
  @bitOrderType bit = 0,                                 -- 排序的类型 (0为升序,1为降序)
  @pkColumn varchar(50) = ''                             -- 主键名称

  DECLARE @strTemp varchar(300)
  DECLARE @strSql varchar(5000)                            -- 该存储过程最后执行的语句
  DECLARE @strOrderType varchar(1000)                    -- 排序类型语句 (order by column asc或者order by column desc)

  BEGIN

      BEGIN
        IF @condition != ''

          ' FROM '+@tableName+@strOrderType+') AS TabTemp)'+@strOrderType
      END

  END
  
  EXEC (@strSql)
END 

执行代码如下：

--  Test Employees Table on Northwind database
EXEC spGetPageOfRecords 5, 2, 'EmployeeID, LastName, FirstName, Title, City, Region, Country', 'Employees', '', 'EmployeeID', 0, 'EmployeeID'


--  Test Customers Table on Northwind database
EXEC spGetPageOfRecords 10, 6, 'CustomerID, CompanyName, ContactName, ContactTitle, Address, City, Region, Country', 'Customers', '', 'CustomerID', 0, 'CustomerID'
