I have a table with a date value that I need to update with a value from
another table.
The table I want to update is profile. The profile table is linked to
the study table with the foreign key StudyID.
the profile table has the date I want to update to the value in the date
value in the study table.
So I can do a simple select like this....
SELECT ProfileID, p.`Date` as `BadDate`, s.`Date` as `GoodDate`
FROM profile JOIN study USING (`StudyID`)
Of course study to profile is a one to many relationship. How do I run
an update to set p.`Date` equal to s.`Date`?
