Not supported by VORTEXjdbc. 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 - unknown 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.

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.

Get a description of the foreign key columns in the foreign key table that reference the primary key columns of the primary key table (describe how one table imports another's key.) This should normally return a single foreign key/primary key pair (most tables only import a foreign key from a table once.) They are ordered by FKTABLE_CAT, FKTABLE_SCHEM, FKTABLE_NAME, and KEY_SEQ.

Each foreign key column description has the following columns:

1. PKTABLE_CAT String => primary key table catalog (may be null)
2. PKTABLE_SCHEM String => primary key table schema (may be null)
3. PKTABLE_NAME String => primary key table name
4. PKCOLUMN_NAME String => primary key column name
5. FKTABLE_CAT String => foreign key table catalog (may be null) being exported (may be null)
6. FKTABLE_SCHEM String => foreign key table schema (may be null) being exported (may be null)
7. FKTABLE_NAME String => foreign key table name being exported
8. FKCOLUMN_NAME String => foreign key column name being exported
9. KEY_SEQ short => sequence number within foreign key
10. UPDATE_RULE short => What happens to foreign key when primary is updated:
    • importedKeyCascade - change imported key to agree with primary key update
    • importedKeyRestrict - do not allow update of primary key if it has been imported
    • importedKeySetNull - change imported key to NULL if its primary key has been updated
11. DELETE_RULE short => What happens to the foreign key when primary is deleted.
    • importedKeyCascade - delete rows that import a deleted key
    • importedKeyRestrict - do not allow delete of primary key if it has been imported
    • importedKeySetNull - change imported key to NULL if its primary key has been deleted
12. FK_NAME String => foreign key identifier (may be null)
13. PK_NAME String => primary key identifier (may be null)

Specified by:

Parameters:

primaryCatalog - a catalog name; "" retrieves those without a catalog

primarySchema - a schema name pattern; "" retrieves those without a schema

primaryTable - a table name

foreignCatalog - a catalog name; "" retrieves those without a catalog

Get a description of all the standard SQL types supported by this database. They are ordered by DATA_TYPE and then by how closely the data type maps to the corresponding JDBC SQL type.

Each type description has the following columns:

1. TYPE_NAME String => Type name

   • typeNoNulls - does not allow NULL values
   • typeNullable - allows NULL values
   • typeNullableUnknown - nullability unknown
8. CASE_SENSITIVE boolean=> is it case sensitive?
9. SEARCHABLE short => can you use "WHERE" based on this type:
   • typePredNone - No support
   • typePredChar - Only supported with WHERE .. LIKE
   • typePredBasic - Supported except for WHERE .. LIKE
   • typeSearchable - Supported for all WHERE ..
10. UNSIGNED_ATTRIBUTE boolean => is it unsigned?
11. FIXED_PREC_SCALE boolean => can it be a money value?
12. AUTO_INCREMENT boolean => can it be used for an auto-increment value?
