Returns:

ResultSet each row is a column description

Throws:

SQLException

getFunctionColumns

public ResultSet getFunctionColumns(String catalog,
 String schemaPattern,
 String functionNamePattern,
 String columnNamePattern)
                             throws SQLException

Retrieves a description of the given catalog's system or user function parameters and return type.

Only descriptions matching the schema, function and parameter name criteria are returned. They are ordered by FUNCTION_CAT, FUNCTION_SCHEM, FUNCTION_NAME and SPECIFIC_ NAME. Within this, the return value, if any, is first. Next are the parameter descriptions in call order. The column descriptions follow in column number order.

Each row in the ResultSet is a parameter description, column description or return type description with the following fields:

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. COLUMN_NAME String => column/parameter name
5. COLUMN_TYPE Short => kind of column/parameter:
   • functionColumnUnknown - nobody knows
   • functionColumnIn - IN parameter
   • functionColumnInOut - INOUT parameter
   • functionColumnOut - OUT parameter
   • functionColumnReturn - function return value
   • functionColumnResult - Indicates that the parameter or column is a column in the ResultSet
6. DATA_TYPE int => SQL type from java.sql.Types
7. TYPE_NAME String => SQL type name, for a UDT type the type name is fully qualified
8. PRECISION int => precision
9. LENGTH int => length in bytes of data
10. SCALE short => scale - null is returned for data types where SCALE is not applicable.
11. RADIX short => radix
12. NULLABLE short => can it contain NULL.
    • functionNoNulls - does not allow NULL values
    • functionNullable - allows NULL values
    • functionNullableUnknown - nullability unknown
13. REMARKS String => comment describing column/parameter
14. CHAR_OCTET_LENGTH int => the maximum length of binary and character based parameters or columns. 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.

Parameters:

catalog - a catalog name; must match the catalog name as it is stored in the database; "" retrieves those without a catalog; null means that the catalog name should not be used to narrow the search

schemaPattern - a schema name pattern; must match the schema name as it is stored in the database; "" retrieves those without a schema; null means that the schema name should not be used to narrow the search

functionNamePattern - a procedure name pattern; must match the function name as it is stored in the database

columnNamePattern - a parameter name pattern; must match the parameter or column name as it is stored in the database

Returns:

ResultSet - each row describes a user function parameter, column or return type

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
