Hi.
I need to obtain a table description in java with MySql database.
The javaapi says:
Java Code:
method:
public ResultSet getTables(String catalog,
                           String schemaPattern,
                           String tableNamePattern,
                           String[] types)
                    throws SQLException

    Retrieves a description of the tables available in the given catalog. Only table descriptions matching the catalog, schema, table name and type criteria are returned. They are ordered by TABLE_TYPE, TABLE_SCHEM and TABLE_NAME.

    Each table 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. TABLE_TYPE String => table type. Typical types are "TABLE", "VIEW", "SYSTEM TABLE", "GLOBAL TEMPORARY", "LOCAL TEMPORARY", "ALIAS", "SYNONYM".
       5. REMARKS String => explanatory comment on the table
       6. TYPE_CAT String => the types catalog (may be null)
       7. TYPE_SCHEM String => the types schema (may be null)
       8. TYPE_NAME String => type name (may be null)
       9. SELF_REFERENCING_COL_NAME String => name of the designated "identifier" column of a typed table (may be null)
      10. REF_GENERATION String => specifies how values in SELF_REFERENCING_COL_NAME are created. Values are "SYSTEM", "USER", "DERIVED". (may be null) 

    Note: Some databases may not return information for all tables.
The REMARKS is my target, but if i try:
Java Code:
Connection con = DriverManager.getConnection("jdbc:mysql://"+args[0],args[1],args[2]);
ResultSet rs = con.getMetaData().getTables(null, null, "AZIONE", null);
while(rs.next()){
		System.out.println(rs.getString(""));
I obtain a blank line.
Why?

Thanks
