```
    Not supported by VORTEXjdbc. Retrieves a description of the pseudo or hidden columns available in a given table within the specified catalog and schema. Pseudo or hidden columns may not always be stored within a table and are not visible in a ResultSet unless they are specified in the query's outermost SELECT list. Pseudo or hidden columns may not necessarily be able to be modified. If there are no pseudo or hidden columns, an empty ResultSet is returned. 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 COLUMN_NAME. 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.COLUMN_SIZE int => column size. 7.DECIMAL_DIGITS int => the number of fractional digits. Null is returned for data types where DECIMAL_DIGITS is not applicable. 8.NUM_PREC_RADIX int => Radix (typically either 10 or 2) 9.COLUMN_USAGE String => The allowed usage for the column. The value returned will correspond to the enum name returned by PseudoColumnUsage.name() 10.REMARKS String => comment describing column (may be null) 11.CHAR_OCTET_LENGTH int => for char types the maximum number of bytes in the column 12.IS_NULLABLE String => ISO rules are used to determine the nullability for a column. YES --- if the column can include NULLs NO --- if the column cannot include NULLs empty string --- if the nullability for the column is unknown The COLUMN_SIZE column specifies the column size for the given column. For numeric data, this is the maximum precision. For character data, this is the length in characters. For datetime datatypes, this is the length in characters of the String representation (assuming the maximum allowed precision of the fractional seconds component). For binary data, this is the length in bytes. For the ROWID datatype, this is the length in bytes. Null is returned for data types where the column size is not applicable.

For any other datatype the returned value is a NULL 15.ORDINAL_POSITION int => the ordinal position, starting from 1, for the input and output parameters. A value of 0 is returned if this row describes the function's return value. For result set columns, it is the ordinal position of the column in the result set starting from 1. 16.IS_NULLABLE String => ISO rules are used to determine the nullability for a parameter or column. YES --- if the parameter or column can include NULLs NO --- if the parameter or column cannot include NULLs empty string --- if the nullability for the parameter or column is unknown 17.SPECIFIC_NAME String => the name which uniquely identifies this function within its schema. This is a user specified, or DBMS generated, name that may be different then the FUNCTION_NAME for example with overload functions The PRECISION column represents the specified column size for the given parameter or column. For numeric data, this is the maximum precision. For character data, this is the length in characters. For datetime datatypes, this is the length in characters of the String representation (assuming the maximum allowed precision of the fractional seconds component). For binary data, this is the length in bytes. For the ROWID datatype, this is the length in bytes. Null is returned for data types where the column size is not applicable.

```
    Retrieves a description of the table hierarchies defined in a particular schema in this database. Only supertable information for tables matching the catalog, schema and table name are returned. The table name parameter may be a fully- qualified name, in which case, the catalog and schemaPattern parameters are ignored. If a table does not have a super table, it is not listed here. Supertables have to be defined in the same catalog and schema as the sub tables. Therefore, the type description does not need to include this information for the supertable. Each type description has the following columns: 1. TABLE_CAT String => the type's catalog (may be null) 2. TABLE_SCHEM String => type's schema (may be null) 3. TABLE_NAME String => type name 4. SUPERTABLE_NAME String => the direct super type's name Note: If the driver does not support type hierarchies, an empty result set is returned.
