Simple getColumnName(0) call throws Invalid column index: getValidColumnIndex

Question

I\'m trying to write a JTable that takes the data from a ResultSet and uses that to create a dynamic sized table with appropriate column names and row data values from the R

Answer 1

Column index starts by 1. So increase your variable pointing column variable by 1.

Answer 2

JDBC column indexes start from 1 and not 0. As far as possible, it is better to retrieve data using column names to avoid hard dependency on the order of columns in the results.
