Hi All,

Can any one suggest some tips for my problems.
my question is I want change string to with modified one . below one is example.
while creating excel template for these changes am adding like one time 10 strings and another time more than 20. in this process am
not getting all modification because while creating template I was given only 10 strings.

am using for sql queries .

string : 12362533
modified one : '12362533',

Thanks ,
