philfeldman Posted September 16, 2006 Share Posted September 16, 2006 The main table is AWARDS. The related tables are PERSONNEL and DOCUMENTS. The primary key is the field LOG NO. When an AWARD record is created, a temporary primary key is assigned, TEMP100. Related PERSONNEL and DOCUMENTS records are created. A few weeks later, a permanent LOG NO.(primary key) is assigned to the AWARDS file. Q: How do I change the primary key (LOG NO.) in all the related records when I change the primary key in the main (AWARDS) file? Right now I am struggling with a lengthy script that uses a global field (gOldKey) and finding each record in the related tables and then executing a REPLACE command. Thanks for your help!

comment Posted September 16, 2006 Share Posted September 16, 2006 The work-flow is not entirely clear: it sounds like once you've created a new Award record, you cannot create any more new records for a few weeks - until someone(?) assigns a permanent number to the Award. Why not use auto-entered serial numbers for the primary key - permanently. Then, when you do get the permanent number, just enter it into a field as another attribute of the parent Award.

philfeldman Posted September 16, 2006 Author Share Posted September 16, 2006 Wouldn't that mean that the value of the key in the related tables (e.g., PERONNEL) would have to be the same value as the key (auto-entered serial number) in the main (AWARDS) table? How would the serial number from AWARDS pass to the key field in the table, PERSONNEL? Are we saying that we pass the auto-entered serial number in AWARDS to a field (not the serial number) in the PERSONNEL file? Thanks... Link to comment Share on other sites More sharing options...
comment Posted September 16, 2006 Share Posted September 16, 2006 I am not sure I understand your question: the value of the foreign key in the child table/s would naturally have to be same as the value of the parent primary key. In that aspect nothing would be changed. The value would be passed to the child in the same way it is now. The only thing changed is that the yet unknown number is not used at all in the relationship. It's just another field in the parent (Awards) table.
