ASP device name. The name of one auxiliary storage pool (ASP) device in the ASP group in which the library and file are located. The ASP device must have a status of 'Available'. The documented authority is required for the given ASP and the primary of the corresponding ASP group. The name can be a specific ASP device name (for an ASP with a number greater than 32), or one of the following special values:
| * | Locate the library and file in the name space for the current thread. |
| *SYSBAS | Locate the library and file in the system ASP (ASP number 1) and all basic ASPs (ASP numbers 2 through 32). |
ASP device name used. The actual auxiliary storage pool device name used, after possible resolution of special values.
Column name. The name of a single column within the statistics collection definition.
Data.; The data returned for the key identifier.
File library name. Where the file for which statistics collections are to be deleted is located. You can use these special values for the library name, if the ASP Device Name is *:
| *CURLIB | The job's current library or QGPL if the current library is not set. |
| *LIBL | The library list. |
| *USRLIBL | Libraries listed in the user portion of the library list. |
File library name used. The actual file library name used, after possible resolution of special values.
File member name. The name of the file member to be used for the delete statistics collections request. This value can be a specific file member name or one of the following special values:
| *FIRST | The first member (in the order created) in the specified file. |
| *LAST | The last member (in the order created) in the specified file. |
File member name used. The actual file member name used, after possible resolution of special values.
File name. The name of the file for which statistics collections are to be deleted. The file has to be an existing local, single format, physical file.
Internal statistics ID. Together with the qualified file name and member name, this represents a unique ID for the statistics collection to be deleted. See List Statistics Collections (QDBSTLS, QdbstListStatistics) API for additional information.
Note: If set to all X'00', all statistics collections for the file member are deleted.
Key identifier. The field returned. For a list of valid keys see Valid Keys - Feedback.
Length of column definition. The length of this column definition.
Length of data. The length of the data returned for the field.
Length of field information returned. The total number of bytes returned for this field in the feedback area.
Number of bytes available. The number of bytes that could be returned in the feedback area.
Number of bytes returned. The number of bytes returned in the feedback area.
Number of columns. The number of columns within the single statistics collection definition. The maximum value for this number is 1. If set to zero, all statistics collections for the file member are deleted.
Number of key fields available.The number of fields that can be returned in the feedback area.
Number of key fields returned. The number of fields returned in the feedback area.
Number of statistics collections deleted. The number of actually deleted statistics collections.
Offset to columns. The offset to the start of the list of column definitions.
Reserved. Reserved for future use. If this field is input, the field must be set to hexadecimal zeros.
Reserved (in feedback area format). Structure padding to guarantee alignment to the next four-byte boundary.
Translation table name. The name of the translation table that was specified, when the statistics collection was requested. The translation table does not necessarily have to exist anymore. The name is used for identification purposes only. The Translation table name can also have the following special values: *JOB indicates the value is retrieved from the job; *LANGIDUNQ indicates the unique weight table that corresponds to the LANGID specified in the Translation table library name field is used; *LANGIDSHR indicates the shared weight table that corresponds to the LANGID specified in the Translation table library name field is used; *NONE indicates a translate table is not used.
Translation table library name. The actual name of the translation table library that was used, when the statistics collection was requested. The translation table library does not necessarily have to exist anymore. The name is used for identification purposes only. If the Translation table name field contains the special value of *LANGIDUNQ or *LANGIDSHR, then the Translation table library name field must contain a corresponding language identifier (LANGID).
