The SYSFUNCS view contains one row for each function created by the CREATE FUNCTION statement. The following table describes the columns in the SYSFUNCS view:
Column Name | System Column Name | Data Type | Description |
---|---|---|---|
SPECIFIC_SCHEMA | SPECSCHEMA | VARCHAR(128) | Schema name of the routine (function) instance. |
SPECIFIC_NAME | SPECNAME | VARCHAR(128) | Specific name of the routine instance. |
ROUTINE_SCHEMA | FUNCSCHEMA | VARCHAR(128) | Name of the SQL schema (schema) that contains the routine. |
ROUTINE_NAME | FUNCNAME | VARCHAR(128) | Name of the routine. |
ROUTINE_CREATED | RTNCREATE | TIMESTAMP | Identifies the timestamp when the routine was created. |
ROUTINE_DEFINER | DEFINER | VARCHAR(128) | Name of the user that defined the routine. |
ROUTINE_BODY | BODY | VARCHAR(8) | The type of the routine body:
|
EXTERNAL_NAME | EXTNAME | VARCHAR(279)
Nullable |
This column identifies the external program
name.
Contains the null value if this is a system-generated function. |
EXTERNAL_LANGUAGE | LANGUAGE | VARCHAR(8)
Nullable |
If this is an external routine, this column
identifies the external program name.
Contains the null value if this is not an external routine. |
PARAMETER_STYLE | PARM_STYLE | VARCHAR(7)
Nullable |
If this is an external routine, this column
identifies the parameter style (calling convention).
Contains the null value if this is not an external routine. |
IS_DETERMINISTIC | DETERMINE | VARCHAR(3) | This column identifies whether the routine
is deterministic. That is, whether a call to the routine with the same arguments
will always return the same result.
|
SQL_DATA_ACCESS | DATAACCESS | VARCHAR(8)
Nullable |
This column identifies whether a routine
contains SQL and whether it reads or modifies data.
|
SQL_PATH | SQL_PATH | VARCHAR(3483)
Nullable |
If this is an SQL routine, this column identifies
the path.
Contains the null value if this is an external routine. |
PARM_SIGNATURE | SIGNATURE | VARCHAR(2048) | This column identifies the routine signature. |
NUMBER_OF_RESULTS | NUMRESULTS | SMALLINT
Nullable |
Identifies the number of results. |
IN_PARMS | IN_PARMS | SMALLINT | Identifies the number of input parameters. 0 indicates that there are no input parameters. |
LONG_COMMENT | REMARKS | VARCHAR(2000)
Nullable |
A character string supplied with the COMMENT
statement.
Contains the null value if there is no long comment. |
ROUTINE_DEFINITION | ROUTINEDEF | VARCHAR(23888)
Nullable |
If this is an SQL routine, this column contains
the SQL routine body.
Contains the null value if this is not an SQL routine or if the routine body cannot be contained in this column without truncation. |
FUNCTION_ORIGIN | ORIGIN | CHAR(1) | Identifies the type of function. If this
is a procedure, this column contains a blank.
|
FUNCTION_TYPE | TYPE | CHAR(1) | Identifies the form of the function. If this
is a procedure, this column contains a blank.
|
EXTERNAL_ACTION | EXT_ACTION | CHAR(1)
Nullable |
Identifies the whether the invocation of
the function has external effects.
|
IS_NULL_CALL | NULL_CALL | VARCHAR(3)
Nullable |
Identifies whether the function needs to
be called if an input parameter is the null value.
|
SCRATCH_PAD | SCRATCHPAD | INTEGER
Nullable |
Identifies whether the address of a static
memory area (scratch pad) is passed to the function.
|
FINAL_CALL | FINAL_CALL | VARCHAR(3)
Nullable |
Indicates whether a final call to the function
should be made to allow the function to clean up its work areas (scratch pads).
|
PARALLELIZABLE | PARALLEL | VARCHAR(3)
Nullable |
Identifies whether the function can be run
in parallel.
|
DBINFO | DBINFO | VARCHAR(3)
Nullable |
Identifies whether information about the
database is passed to the function.
|
SOURCE_ SPECIFIC_SCHEMA | SRCSCHEMA | VARCHAR(128)
Nullable |
If this is sourced function and the source
is user-defined, this column contains the name of the source schema. If this
is a sourced function and the source is built-in, this column contains 'QSYS2'.
Contains the null value if this is not a sourced function. |
SOURCE_SPECIFIC_NAME | SRCNAME | VARCHAR(128)
Nullable |
If this is sourced function and the source
is user-defined, this column contains the specific name of the source function
name.
Contains the null value if this is not a sourced function. |
IS_USER_DEFINED_CAST | CAST_FUNC | VARCHAR(3)
Nullable |
Identifies whether this function is a cast
function created when a distinct type was created.
|
CARDINALITY | CARD | BIGINT
Nullable |
Specifies the cardinality for a table function.
Contains the null value if the function is not a table function or if cardinality was not specified. |
FENCED | FENCED | VARCHAR(3)
Nullable |
Identifies whether the function is fenced.
|
IASP_NUMBER | IASPNUMBER | SMALLINT | Specifies the independent auxiliary storage pool (IASP) number. |
