Number and name of rows

Question

Is there any way to know the total number and the names of the rows in a table?

Answer 1

Sample:
private void loadMetaData() {
int i = 0;
try {
metaData = rs.getMetaData();
int singleHtColumnType;
columnCount = metaData.getColumnCount();
for (i = 1; i <= columnCount; i++) {
columnNames[i-1] = new String(metaData.getColumnName(i));
// System.out.println("meta-look " + columnNames[i-1]);
// System.out.println(metaData.getColumnLabel(i)); // on AS/400 == columnName :-((
// System.out.println("ColumnDisplaySize: " + metaData.getColumnDisplaySize(i));
singleHtColumnType = metaData.getColumnType(i);
if (readBigDecimalAsInt & singleHtColumnType == 8) singleHtColumnType = 4;
columnType[i-1] = singleHtColumnType;
if (singleHtColumnType == 8
|| (databaseType == ConnectionHolder.DB2_400 && singleHtColumnType == 3)) {
columnScale[i-1] = metaData.getScale(i);
htColumnType.put(columnNames[i-1], new Integer(singleHtColumnType));
if (singleHtColumnType == 1 | singleHtColumnType == 12) maxFieldSize.put(columnNames[i-1], new Integer(getColumnDisplaySize(i)));
catch (SQLException e2) {
System.out.println("loadMetaData caught " + e2);
System.out.println("Index was " + i);
catch (Exception e) {
System.out.println("loadMetaData caught " + e);
System.out.println("Index was " + i);
