Why Does My Oracle Query Throw a 'java.sql.SQLException: Exhausted ResultSet' Error?

Troubleshooting "java.sql.SQLException: Exhausted Resultset" During Oracle Query Execution

When attempting to execute a query against an Oracle database from within a Websphere connection pool, an error message stating "java.sql.SQLException: Exhausted ResultSet" may appear. This error typically arises when trying to access a column value after the resultset has been processed.

The provided Java code snippet illustrates the issue:

if (rs != null) {
  while (rs.next()) {
    count = rs.getInt(1);
  }
  count = rs.getInt(1); //this will throw Exhausted resultset
}

When accessing a column value after the resultset has been completed, this code snippet retrieves the value successfully in the first iteration (when count = rs.getInt(1)) but fails in subsequent iterations, resulting in the "Exhausted ResultSet" error.

To resolve this issue, ensure that all column values are accessed within the loop that processes the resultset:

if (rs != null) {
  while (rs.next()) {
    count = rs.getInt(1);
    // Add additional code here to access other column values
  }
}
