Need MSSQL expert

We need a script or procedure that can convert how data is stored Data is now stored in a table with 2 cols: Header and Data Format of data in these cols are: Header // Data email;name;phone // [login to view URL];john;12345 The output format must be a string: email=[login to view URL];name=john;phone=12345 The number of headers/datapairs will vary so the script has to take this into account and be flexible
