Thanks for your inquiry. I have tried to understand your query and as per my understanding, you want to filter records from DataTable and convert integer value to string of specific column.
If this is the case, I suggest you please use CAST and CONVERT method in your sql when you get ResultSet object to convert integer value to string. So, in DataTable the specific column will have string values. Regarding filtering records from DataTable, there is no direct way to find a specific record. You need to iterate through DataTable’s rows and find specific record. You can get the rows of DataTable using DataTable.getRows. Please read the members of DataTable class from here:
