```
    Get a description of table columns available in a catalog.
    Only column descriptions matching the catalog, schema, table and column name criteria are returned. They are ordered by 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 short => SQL type from java.sql.Types
    6. TYPE_NAME String => Data source dependent type name
    7. COLUMN_SIZE int => column size. For char or date types this is the maximum number of characters, for numeric or decimal types this is precision.
    8. BUFFER_LENGTH is not used.
    9. DECIMAL_DIGITS int => the number of fractional digits
    10. NUM_PREC_RADIX int => Radix (typically either 10 or 2)
    11. NULLABLE int => is NULL allowed?
      
      columnNoNulls - might not allow NULL values
      columnNullable - definitely allows NULL values
      columnNullableUnknown - nullability unknown
    12. REMARKS String => comment describing column (may be null)
    13. COLUMN_DEF String => default value (may be null)
    14. SQL_DATA_TYPE int => unused
    15. SQL_DATETIME_SUB int => unused
    16. CHAR_OCTET_LENGTH int => for char types the maximum number of bytes in the column
    17. ORDINAL_POSITION int => index of column in table (starting at 1)
    18. IS_NULLABLE String => "NO" means column definitely does not allow NULL values; "YES" means the column might allow NULL values. An empty string means nobody knows.
    Parameters:
    catalog - a catalog name; "" retrieves those without a catalog; null means drop catalog name from the selection criteria
    schema - a schema name pattern; "" retrieves those without a schema
    tableName - a table name pattern
    columnName - a column name pattern
    
    Returns:
    a Vector of Records.
    
    Throws:
