Dear Loungers,
If I am developing an asp db. I will use a Lookup based on a reference table, my question is how is this implemented? If I have a regular relational db then the lookup is based on a foreign key to the reference data table, I would use a numeric ID field and them retrieve the text value from the reference table for display purposes. However Access 2013 the db offered lookup as a data type and on selecting the table I can select the field to display. If I choose the ‘name’ field in the table what is stored in the table with the Lookup field? The reason I need to know is to understand what happens if, for example, the ‘name’ of an existing record in the reference table changes – will it also change on related records?
Thank you………………….. liz
