Creating new row in other table
Dear All,
Please teach me, how to make a new row/list in other table by entering number in other table. Sample, In the table A and in the field "Details", I put the number 2 and it automatically creates two rows in table B. Can this be done in MS Access? Thank you for your help. Regards, Maulwy |

Creating new row in other table
Why? What business need are you attempting to solve with this approach?
It's generally considered not very good database design to be creating 'empty' rows in a second table. Why do you want empty rows? And if the number you enter in TableA is a 'limit', why not just create new rows in TableB (related, of course), until that limit is reached? -- Regards Jeff Boyce Microsoft Access MVP Disclaimer: This author may have received products and services mentioned in this post.

Creating new row in other table
Dear Jeff & John, For example, if we do a sales order, where there is a column for the model, quantity and serial number. To model and quantity, comes from one table, while for the serial number, which I want, be inputted in the other table. But not all existing models, has a serial number, this is the basic one, the serial number I did not join in a single table. To avoid input mistakes serial number, if the quantity, I suppose input 2, then automatically, the database will add the 2 lines at the next table (the serial number tables). Database like this is what I mean. Example data: Model TransID Qty 1 AAA 2 2 BBB 3 TransID SerialNumber 1 AAAXXX01 1 AAAXXX02 2 BBBXXX01 2 BBBXXX50 2 BBBXXX65 Rgds, Maulwy "John W.

Dear All,
Sorry, the example should be: TransID Model Qty 1 AAA 2 2 BBB 3 TransID SerialNumber 1 AAAXXX01 1 AAAXXX02 2 BBBXXX01 2 BBBXXX50 2 BBBXXX65 (null?)

Creating new row in other table
Why not use a form instead of table A? Where will the query get the serial
numbers to use in table B? -- Build a little, test a little.
