The columns not appear

Question

Here i want to get the columns names in the table "employee" in my database so i used databaseMetaData.getColumns(); but give me this error:
java.sql.SQLException: Column not found
at sun.jdbc.odbc.JdbcOdbcResultSet.findColumn(JdbcOdbcResultSet.java:1850)
why this ?
code:
import java.sql.Connection; import java.sql.DatabaseMetaData; import java.sql.DriverManager; import java.sql.ResultSet; public class ColumnNamesTest {     private static final String DRIVER = "sun.jdbc.odbc.JdbcOdbcDriver";     private static final String DRIVER_URL = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};" +             "Dbq=D:\\my _works\\my_works_2010\\JDBC-work\\employeedb\\Database2.mdb";     public ColumnNamesTest() {         Connection connection = null;         //  Statement statement = null;         ResultSet resultSet = null;         try {             Class.forName(DRIVER);             connection = DriverManager.getConnection(DRIVER_URL);             DatabaseMetaData databaseMetaData = connection.getMetaData();             resultSet = databaseMetaData.getColumns(null, null, "Employee", null);             while (resultSet.next()) {                 String colName = resultSet.getString("Column Names");                 System.out.println(colName);             }         } catch (Exception e) {             e.printStackTrace();         }     }     public static void main(String[] args) {         new ColumnNamesTest();     } }
Thanks

Answer 1

A combination of this
getColumnsResultSet getColumns(String catalog,
String schemaPattern,
String tableNamePattern,
String columnNamePattern)
throws SQLException
Retrieves a description of table columns available in the specified catalog.
Only column descriptions matching the catalog, schema, table and column name criteria are returned. They are ordered by TABLE_CAT,TABLE_SCHEM, TABLE_NAME, and ORDINAL_POSITION.
Each column description has the following columns:
1. TABLE_CAT String => table catalog (may be null)
2. TABLE_SCHEM String => table schema (may be null)
3. TABLE_NAME String => table name
4. COLUMN_NAME String => column name
5. DATA_TYPE int => SQL type from java.sql.Types
6. TYPE_NAME String => Data source dependent type name, for a UDT the type name is fully qualified
...>
And this
getStringString getString(int columnIndex)
throws SQLException
Retrieves the value of the designated column in the current row of this ResultSet object as a String in the Java programming language.
