hii you can also use below query declare @t varchar(10)@var VARCHAR(max)='@test123'; declare @t1 int=1@t2 varchar(10); while(SUBSTRING (@var @t1 1)!=' ') begin set @t1=@t1+1 set @t=SUBSTRING (@var @t1 1); if(@t='') begin select @t1-1; return; end end

Hi venkatesh i just write on the go try if you find something helpful just pass any string at place of ABC12 DECLARE @A VARCHAR ( max )= 'ABC12'  @myChar VARCHAR (2)= '@'  @repVal VARCHAR ( max ) SET @repVal= REPLACE (@A '@'  '_' ) SET @repVal=@repVal+@myChar SELECT CHARINDEX( '@' @repVal)-1
