SQL Server stored procedure paging code 1th/2 page

Copy CodeThe code is as follows:
DECLARE @TotalCount int
DECLARE @TotalPageCount int
exec p_viewpage_a ' type1 ', ' * ', ' id ', ', ' ID ASC ', 1,0,4,3, @TotalCount output, @TotalPageCount output

SELECT * FROM Type1


Create PROC p_viewpage_a

@TableName VARCHAR (200),--table name
@FieldList VARCHAR (2000),--Display column names, if all fields are *
@PrimaryKey VARCHAR (100),--single primary key or unique value key
@Where VARCHAR (2000),--the query condition does not contain a ' Where ' character, such as Id>10 and Len (userid) >9
@Order VARCHAR (1000),--sorting does not contain an ' order by ' character, such as ID Asc,userid desc, you must specify ASC or DESC
-Note that when the @sorttype=3 comes into effect, remember to add the primary key at the end, otherwise it will make you more depressed
@SortType INT,--collation 1: Positive order ASC 2: Reverse DESC 3: Multi-column Sorting method
@RecorderCount INT,--Total records 0: Returns the total record
@PageSize INT--number of records output per page
@PageIndex INT,--current page number
@TotalCount INT OUTPUT,--Returns the total record
@TotalPageCount INT OUTPUT--Total number of pages returned
