Declare @SBUCode2 varchar(50)
Declare @Percentage2 varchar(50)
Declare @CONTROLID2 int
Declare @countSBU int,@countPER int
Declare @SBU int,@PER numeric
Declare sBUCur cursor local scroll for Select CONTROLID,SBUCode,Percentage from #tblAcVoucherFinal where CONTROLID= @CONTROLID
open sBUCur
fetch next from sBUCur into @CONTROLID2,@SBUCode2,@Percentage2
while not @@fetch_status <> 0
Begin

--here its getting count of SBU after splitting commas
Select @countSBU= count(*) from dbo.split(@SBUCode2,',')

declare @I int=0
WHILE @I <= @countSBU-1
BEGIN
--here its getting value of SBU n Percentage as per ID from Split Function and Saving in table
Select @SBU=Value from dbo.split(@SBUCode2,',') where id=@I
Select @PER=Value from dbo.split(@Percentage2,',') where id=@I

Insert into tblAcvoucherDetails_SBU (VNo,SBUCode,Percentage,TransDate,UserID)
Values(@VNo,@SBU,@PER ,@Trans_Date,@UserID)

SET @I = @I + 1
END

fetch next from sBUCur into @CONTROLID2,@SBUCode2,@Percentage2

Differents between Cast and Convert function using Sql Server

1.select distinct cast(FromDate as Varchar) FromDate from tblpolicymaster where policyno=234000211

2.select distinct Convert(Varchar,FromDate,103) FromDate from tblpolicymaster where policyno=234000211

3.using both cast & convert
select distinct cast(Convert(Varchar,FromDate,103)as varchar) FromDate from tblpolicymaster where policyno=234000211

Example of Left, Right, Charindex, Patindex using Sql Server

like left
select substring(jobdesc, 0, charindex('Teachers are not eligible for overtime because', jobdesc)) from Order_Gen where Client=48670

--1.Right
select RIGHT(CEM.ReimbHospital,CHARINDEX('-',REVERSE(CEM.ReimbHospital)) - 1) from tblClaimsEntryMaster cem WHERE cem.ClaimNo=234006607

--1.Left
select Left(CEM.ReimbHospital,CHARINDEX('-',(CEM.ReimbHospital)) - 1) from tblClaimsEntryMaster cem WHERE cem.ClaimNo=234006607

--2.Right
select right(policyname, len(policyname)-charindex('-',policyname)) from tblpolicy
select RIGHT('policy-12',9-7)
--ans->12

--2.Left
select left(policyname, charindex('-',policyname)-1 ) from tblpolicy
select LEFT('policy-12',7-1)
--ans->policy

--it returns one value
select left(ClientName,CHARINDEX(' ',ClientName)-1) from tblClientMaster where ClientNo=89 or ClientNo=71

select left('Client Name',CHARINDEX(' ','Client Name')-1)
--it returns the word frm left when see the space

select right('Client dName',CHARINDEX(' ','Client dName')-1)
--it returns the word frm right when see the space

--it returns multiple value
select left(ClientName,CHARINDEX(' ',ClientName,1)) from tblClientMaster
--it returns 1st word frm left

select right(ClientName,CHARINDEX(' ',ClientName,1)) from tblClientMaster
--it returns 1st word frm right--wrong

select CHARINDEX(' ','Client Name') --it return position of space-7

--It returns 3 letters from left and right
select left(ClientName,3) from tblClientMaster
select right(ClientName,3) from tblClientMaster

-- I need to get the last RIGHT 3 characters and I need to get whatever is to the LEFT
select right(ClientName,3),LEFT(ClientName,LEN(ClientName)-3) from tblClientMaster

-- finds the position at which the pattern ensure starts in a specific row of the Clientname column in the Document table in the AdventureWorks2012 database.
select PATINDEX('%MANSARD%',Clientname) from tblClientMaster

SELECT PATINDEX ( '%ein%', 'Das ist ein Test')
SELECT PATINDEX('%en_ure%', 'please ensure the door is locked')

Differents between STUFF and REPLACE in Sql Server

1.Select STUFF ('this is a test', 6,2, 'was')

o/p:-this was a test

2.Select REPLACE ('That is a test and it is successful!','is','was')

o/p:- That was a test and it was successful!

Adding comma using STUFF in Sql Server

1.select distinct id,name,

from test t2

2.SELECT DISTINCT StateId, StateName
, STUFF((SELECT ','+City
FROM [StateProvince] S2
WHERE S1.StateId = S2.StateId
FOR XML PATH('')), 1, 1, '') AS City
FROM [StateProvince] S1

How to get unique record in Sql Server

create table test(id int,name varchar(30),descrptn varchar(30))

1.(it contain duplicate records)
select * from test
--here this table(test1) only keep unique records
select distinct * into test1 from test
--here drop the table test
drop table test
--here rename the table test1 to test
sp_rename test1,test

OR

2.(it contain duplicate records)
select * from test
--here this table(test1) only keep unique records
select distinct * into test1 from test
select * from test1
--here delete all the records of table(test) test
truncate table test
select * from test
--here insert one whole table(test1) records into another table(test)
insert into test select * from test1
select * from test
-- then we can drop the table(test1)
drop table test1

OR

insert into test select * from test
3.(it contain duplicate records)
select * from test
--select whole query given below and exucute,we will get unique records
with cte as(
select id,name,descrptn,RN = ROW_NUMBER()OVER(PARTITION BY id ORDER BY id)
FROM test
)
DELETE FROM CTE WHERE RN > 1

Example of Pivot in Sql Server

SELECT ClientNo,isnull([1],0) [0-30],isnull([2],0) [31-60],isnull([3],0) [61-90],isnull([4],0) [>90],BrokerName,AsOfDate,UserName
From (Select Amount,ClientNo,DaysInGroup,BrokerName,AsOfDate,UserName FROM #tblPivot) a
PIVOT( sum(Amount)
FOR DaysInGroup IN ([1],[2],[3],[4])) AS PVTTable1

How to call client side function from Server side or vice versa in VB.Net

1st option

ClientScript.RegisterClientScriptBlock(Page, typeof"Validate(ID), true);

OR

<asp:Button OnClientClick = "Validate(ID)"/>

Use this on page load:

RegisterStartupScript("Unique key", "Validate(ID);");

2nd option

protected void MyButton_Click(object sender, EventArgs e)
{
Page.ClientScript.RegisterStartupScript(this.GetType(), "myScript", "AnotherFunction();", true);
