Question

I am taking my first stumbling steps into DB aware controls (any good tutorials?).

I have a MySql table with 6 columns and have managed to load it into a TDbGrid.

One of the columns however is an index into another table. It is a bar code and, rather than display that, I would like to display the product name associated with it.

How do I do that?

(and can I hide the “gutter” (?) down the left whcih shows the current row?)

Thanks

You should always perform a join from the SQL side, it’s much easier then doing it programaticaly

Such as:

SELECT mytable.id, mytable.column1, another_table.barcode
FROM mytable
JOIN another_table ON another_table.id = mytable.barcode_id

To remove gutter you need to uncheck the DBGrid property dgIndicator in Options.

As for “DB-Aware controls” you should try delphi help.
