Presently, the GUI mode only let's you use bulk update if your table has a single-column primary key in MySQL. However, for some data sets a composite primary key is the choice we have available. Using only a single column for the update would not correctly identify the record to update. Take the following simple example:
CREATE TABLE foo (
user_id int(10) unsigned not null,
location_id int(10) unsigned not null,
rating int(3) unsigned not null,
PRIMARY KEY(user_id, location_id)
)
In this case, I'd like to update based on the tuple of user_id and location_id, either one is insufficient to identify the record on its own.
Thanks Justin, I, of course, do use the loop around a sql query via js query pattern, since I don't want to turn off placeholder parsing for the whole database connection (which would let me generate all the updates using INSERT ... ON DUPLICATE KEY UPDATE by quickly crafting a string with parenthetical lists).
However, it's a lot of work relative to the GUI mode, and enabling composite keys in bulk upserts via the GUI is much easier on me =)
I'm new to retool and straight away encountered this problem -- in SQL there's this great word you can use with UPDATE statements, it's called "AND" -- don't know why retool haven't heard of it...
Hey @tgomax, this has not been implemented yet. I'll update this topic when there is anything new to share. We've got a good example of looping through data and calling a query with additional scope in our docs here.
