DTLDESCRIBE COLUMNS Qualifier

Enables you to list the available columns:

dtldescribe columns, [qualifier1], [qualifier2], [table_name],[comments], [ORDER], [escape_character], [respect_case1], [respect_case2], [respect_case3], [extended_information], [access_method]

After the basic syntax of

dtldescribe columns

, 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	Always NULL if the dtldescribe operation is done by using NRDB2. Otherwise, this parameter returns the PowerExchange data map name.
table_name	The primary table qualifier. Returns the table name. If this parameter is blank, returns columns for all available tables.
comments	If set to Y this will return any comments data found in the database.
ORDER	Optional argument, Y will force order by column number or blank will leave column order undefined.
escape_character	Specifies the character to be used as the escape character. Default is ~.
respect_case1 respect_case2 respect_case3	Set to Y this will respect the case of qualifier1, qualifier2 and tablename respectively - alternative is blank.
extended_information	Set this parameter to Y to return 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 no extended information is required.
access_method	For NRDB, NRDB2, CAPX, and CAPXRT only. Specifies the valid access method or methods for which information is returned. The results of the DTLDESCRIBE are filtered to return information only for the specified access methods. Use this method to return a list of data maps applicable for certain access methods. You can use any number or combination of access method identifiers. If you specify no value, the DTLDESCRIBE returns all access methods.
