I want to check data with in a json string exists or not exists in a table .
I am passing a json string which contains reference no: I am using Sql server 2008.

json string is as below:
{"Login_Id":"alex.maker","User_Name":"Samuel Jacob","Email_Id":"Samuel.Jacob@nestgroup.net","Mode":"M","Corporate_ID":"NeST","Establishment_ID":"12345678911830098344779998855552331","Reference_No":"IB120219100105"}'

What I have tried:

Tried as below:

declare @ReferenceNo varchar(max) ='IB120219100105'
set @ReferenceNo='{"Login_Id":"alex.maker","User_Name":"Samuel Jacob","Email_Id":"Samuel.Jacob@nestgroup.net","Mode":"M","Corporate_ID":"NeST","Establishment_ID":"12345678911830098344779998855552331","Reference_No":"IB120219100105"}'

SELECT * FROM User_Sync_Log WHERE  
SyncLogRequest LIKE   '%Reference_No": "%'+@ReferenceNo+'"%'

But no data coming

It is not validation (that would be a syntax check), but actually using the data from within SQL...
What version of SQL do you have?

Are you sure you have a record in your table where the SyncLogRequest column matches the pattern:

'%Reference_No": "%{"Login_Id":"alex.maker","User_Name":"Samuel Jacob","Email_Id":"Samuel.Jacob@nestgroup.net","Mode":"M","Corporate_ID":"NeST","Establishment_ID":"12345678911830098344779998855552331","Reference_No":"IB120219100105"}"%

NB: You've overwritten the @ReferenceNo variable immediately after declaring it. I don't think you meant to do that.

Before 2016 there is nothing built in you can use... You have to write your own JSON parsing functions in SQL...
There is a good sample here to start with:
