Ye' old general discussion board. Basically, for everything that isn't covered elsewhere. Come here to shoot the breeze, shoot your mouth off, or whatever suits your fancy. This forum is not for asking programming related questions.
With a table selected and you click on "Browse" the table, the rows are listed with each row having a little pencil displayed and a red "X" for editing or deleting the row. Sometimes, however, one or both are missing and just a small question mark is in its place. When I mouse over that column the cursor changes to the "What's this" symbol and the tool tip (sometimes) reads "you should define a primary key for this table."
Can anyone tell me what is causing that?
(Cannot define a primary key, by the way. The table contains no unique fields.)
Yeah, I'm using the cbeck boxes and bottom links, so it's not a problem really.
But it's jsut wierd. I thought at first there was something wrong with the records...
what it probably is is the iconic ones use primary key only, but the check boxes are using a more flexible selection system because it allows multiple records to be edited at a time...
Remember - if you don't define a Primary/Unique key, then any manager must assume no one entry is entirely unique. So entry by entry changes become impossible unless you manually select (hence the checkbox/bottom buttons).
I think I get it. The bottom ones present multiple selections for you to pick from. Even though the multiple might be only one because that's all that was checked, the prinpiple still applies.
The indiv icons always present an individual record, but they can't always do that without a primary key. Makes sense.
