How to Resolve 'java.sql.SQLException: Exhausted ResultSet' in Java?

Resolving "java.sql.SQLException: Exhausted ResultSet" Error

When executing queries against an Oracle database through a connection pool in Websphere, one may encounter the "java.sql.SQLException: Exhausted ResultSet" error. To address this error, let's delve into the provided code snippet:

if (rs != null) {
  while (rs.next()) {
    count = rs.getInt(1);
  }
}

In this code, you iterate through the result set using the rs.next() method. However, the error arises when attempting to access the count variable outside of the loop. This is because the result set is now exhausted, meaning it has no more rows to process.

Therefore, to correct this issue, ensure that any column value access occurs within the loop:

if (rs != null) {
  while (rs.next()) {
    int count = rs.getInt(1);
    // Use the 'count' variable here
  }
}

By following this approach, you can effectively handle the "java.sql.SQLException: Exhausted ResultSet" error and access column values correctly.
