DTLDESCRIBE RECORDS Qualifier

DTLDESCRIBE RECORDS Qualifier

Enables you to list the available columns. Applicable to NRDB and NRDB2.
dtldescribe records,[
qualifier1
], [
qualifier2
], [
table_name
], [
comments
], [ORDER], [
escape_character
], [
respect_case1
], [
respect_case2
], [
respect_case3
], [
extended_information
], [
access_method
]
After the basic syntax of
dtldescribe records
, all of the parameters in brackets [ ] are optional. If any of the parameters are coded, you must include the intervening commas so that the parser can determine which field is included.
The following table describes the parameters:
Parameter
Description
qualifier1
,
qualifier2
Creator or schema name.
table_name
The primary table qualifier. If this parameter is blank, returns records for all available tables.
comments
Set this parameter to Y to return any comments found in data in the database.
ORDER
This field must be left blank except for a comma, which is needed to maintain the position of subsequent fields.
escape_character
Specifies the character to be used as the escape character. Default is the ~ character.
respect_case1
,
respect_case2
,
respect_case3
Set these parameters to Y to respect the case of the
qualifier1
,
qualifier2
and
table_name
values, respectively. Or leave these parameters blank.
extended_information
Set this parameter to Y to returns additional information that depends on the data access method.
Applicable to NRDB, NRDB2, DB2 for z/OS, and DB2 for i5/OS only.
Defaults to N, which indicates that no extended information is required.
access_method
For NRDB,NRDB2, CAPX, and CAPXRT only:
Specifies the valid access methods for which information is returned. The results of the DTLDESCRIBE are filtered to return information for only the specified access methods. This is useful to return a list of data maps that are applicable for certain access methods. Any number or combination of access method identifiers can be used, such as OS or AKTM. If no value is used, the DTLDESCRIBE defaults to return all access method.
