getPseudoColumns

public ResultSet getPseudoColumns(String catalog,
                                  String schemaPattern,
                                  String tableNamePattern,
                                  String columnNamePattern)
                           throws SQLException

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.

15. SQL_DATA_TYPE int => reserved for future use
16. SQL_DATETIME_SUB int => reserved for future use
17. CHAR_OCTET_LENGTH int => the maximum length of binary and character based columns. For any other datatype the returned value is a NULL
18. ORDINAL_POSITION int => the ordinal position, starting from 1, for the input and output parameters for a procedure. A value of 0 is returned if this row describes the procedure's return value. For result set columns, it is the ordinal position of the column in the result set starting from 1. If there are multiple result sets, the column ordinal positions are implementation defined.
19. 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
20. SPECIFIC_NAME String => the name which uniquely identifies this procedure within its schema.

Note: Some databases may not return the column descriptions for a procedure.

The PRECISION column represents the specified 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.

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.

getFunctions

public ResultSet getFunctions(String catalog,
                              String schemaPattern,
                              String functionNamePattern)
                       throws SQLException

Retrieves a description of the system and user functions available in the given catalog. Only system and user function descriptions matching the schema and function name criteria are returned. They are ordered by FUNCTION_CAT, FUNCTION_SCHEM, FUNCTION_NAME and SPECIFIC_ NAME.

Each function description has the the following columns:

1. FUNCTION_CAT String => function catalog (may be null)
2. FUNCTION_SCHEM String => function schema (may be null)
3. FUNCTION_NAME String => function name. This is the name used to invoke the function
4. REMARKS String => explanatory comment on the function
5. FUNCTION_TYPE short => kind of function:
   • functionResultUnknown - Cannot determine if a return value or table will be returned
   • functionNoTable- Does not return a table
   • functionReturnsTable - Returns a table
6. 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

A user may not have permission to execute any of the functions that are returned by getFunctions

Specified by:
