>good day! i'm having trouble with parent-child relationship. one typical exampleis the ITEM_CATEGORY & ITEM:

>ITEM_CATEGORY
>- item_cat_code (primary key)
>- item_cat_desc
>
>ITEM
>- item_cat_code (foreign key)
>- item_code (primary key)
>- item_desc
>
>i'm using ADO recordsets (rsItem_Category & rsItem), how do i make my rsItem automatically contain the related records everytime my rsItem_Category moves to another row.
>to illustrate here's a sample data:
>rsItem_Category
>item_cat_code item_cat_desc
>FRTS FRUITS
>VEGE VEGETABLES
>
>rsItem
>item_cat_code item_code item_desc
>FRTS APPL APPLE
>VEGE TOM TOMATO
>VEGE LET LETTUCE

>as i was saying, when rsItem_Category is in the second record (item_cat_code = 'VEGE'), rsItem should have these records (item_code = 'TOM', item_code = 'LET').

The Item recordset is a child of the Category recordset. To be able to play with the child (display, add, delete, update), you need to copy the child to another temp recordset. Open your Category recordset (which will contain the hierarchy), loop through the category recordset and when you need to play with the child recordset, do this:

Set rstTempChild = rstCategory.Fields("Item").Value
