----- 表名或能查询到结果的SQL语句{SQL语句左右必须有括号例:(select * from tbl1)}
@TableNamevarchar(max),
----- 要查询的列名语句; 可空默认*
@ColumnNamevarchar(5000),
----- 用来排序的列; 不可为空
@OrderByColumnNamevarchar(50),
----- 排序desc(倒序5.4.3.2.1)或asc(正序1.2.3.4.5); 可空默认asc
@ShrtByvarchar(4),
----- Where条件; 可空默认1=1
@Wherevarchar(5000),
----- 每页显示数; 可空默认20
@PageShowsint,
----- 当前页数; 可空默认1
@CurrentPageint,
----- 0为分页查询;其他为查询全部; 可空默认0
@IsPagingint

----- 定义
-- 拼接的SQL语句
declare@SqlStr nvarchar(max);

-- 开始条数
