Table variable acts like general table to  store, update, delete and delete records. Table variable store in TempDB in sqlserver. I will explain TempDB in later. Table variable declaration similar to CREATE TABLE Statement Declaration : DECLARE @MyProducts TABLE (        Id                 INT       , ProductName  VARCHAR ( 200 )       , Price              numeric ( 18 , 0 ) ) DML Operation: DML operation as it is general table operation.

In this article you learn how to fetch data according PageIndex and PageSize. In web application, it is much more important to increase webform performance, loadbalance. In my development experience, some of table hold large amount of records (more than 2GB) and user need to shows records in GridView. But problem is when we select all records and loads in webforms, webform has crashed. In that case, I will simply solved with Table Variable and using Grid Page Number and Page Size. 1. Create Procedure CREATE PROCEDURE Load_Data_WithPaging @PageIndex AS INT , /*Selected Row Index of selected grid*/ @PageSize AS INT , /*Total page size of selected grid*/ @TotalRecords AS INT OUT /*used for display virtual page no*/ AS BEGIN SET NOCOUNT ON ; DECLARE @FromIndex AS INT = 0 , @ToIndex AS INT = 0 ; SET @FromIndex = (@PageIndex * @PageSize) + 1 ; /*First row no selection*/ SET @ToIndex = ((@PageIndex...

Password matching expression. Password must be at least 4 characters, no more than 8 characters, and must include at least one upper case letter, one lower case letter, and one numeric digit.

Minimum length 8" )] [ Display (Name = "Password" )] public string Password { get ; set ; } }

Usually used in Select Statement. ROW_NUMBER () OVER ( [ <partition_by_clause> ] <order_by_clause> )  Arguments: ROW_NUMBER has Two Arguments are  1. Partition_by_clause and 2.   order_by_clause  ROW_NUMBER() with PARTITION : Partition BY Clause to generate Sequence No to separate of query result and Order By works on over clause for order the results. SELECT  ROW_NUMBER() OVER(PARTITION BY IsApproved ORDER BY Id DESC ) AS SL_NO ,[Name]       ,[Address]       ,[Telephone]  ,[IsApproved]       FROM [RemitERP].[dbo].[Agm_Agent]  WHERE IsApproved IS NOT NULL ROW_NUMBER()   Only  ORDER BY : Order by clause works all result of the query and generate sequence No.  SELE...
