The following code throws an Exception with the postgresql jdbc driver. This code does work with the MySQL and HSQL JDBC drivers and it looks correct to me. The call to getString(..) is what is causing the exception. It appears the result set is considered closed even though ResultSet.next() returns true in this case. Any help would be appreciated. Thanks.
Info:
Server Version = 8.0.3
JDBC Driver Version = 8.0 Build 312
Code that causes exception:
ResultSet rstVersionColumns=meta.getVersionColumns(null, null, tableName);
while (rstVersionColumns.next())
{
String fieldName=rstColumn.getString("COLUMN_NAME"); // Exception thrown here
if (_logger.isDebugEnabled())
_logger.debug("Version field "+fieldName);
// [snip]
}
