Retrieve the ID of a date-sensitive child record#
Functionality:#
This function retrieves the ID for a date sensitive record given a parent alias and ID (and optional as of date)Parameters:#
| TABLE_ALIAS | The table alias (e.g. EID) of the parent table (not the child table) |
| PARENT ID | The ID of the parent record |
| AS OF | Optional. Provides a date frame to retrieve the data. If it is not provided, the current system date will be used. |
Returns: #
Varchar2 (even though the return value is a numeric ID)Errors: #
| ** BAD Table Alias | When there is no table found in IMTD with the alias provided |
| ** No UK constraint found with ... | When the table alias provided does not have a date sensitive child table |
| ** Select failed on child table ... | When a date sensitive child record could not be located as of the date specified |
Example: #
p2k_pu.get_child_id('DWR',dwr_id)
- will return the ID of the effective record from P2K_CM_WORK_RULE_DETAILS (the child of DWR - P2K_CM_WORK_RULES) as of today
Where this could be used is if you know the information of a header record, but now want to get something from the date-sensitive detail. You can use the combination of the P2K_PU.GC function and this function to get the column information from the child record.
For example, If I know the Work Rule (DWR) and I want to get the Standard Hours per day from the date sensitive detail (DWRD), the reference would be:
p2k_pu.gc('DWRD','STD_HOURS_PER_DAY', p2k_pu.get_child_id('DWR',dwr_id) )
