I want to UPDATE my database from a previous selection. I mean I need to select the minium value of the register when the boolean=false and then change the value of the boolean of that record to true. They are all from the same table.
numberColumn booleanColumn
1 1
2 1
3 0
4 0
Result need to be this:
numberColumn booleanColumn
1 1
2 1
3 1
4 0
The statement im using is like this and there is probably an error on the syntax.
"UPDATE db(booleanColumn) SELECT MIN(numberColumn) FROM db WHERE boolean='0' SET boolean='1'"
Im feeling like I need to nest something like:
"UPDATE db(booleanColumn)
SET boolean='1'
WHERE (SELECT MIN(numberColumn) WHERE boolean=0)"
but if not working also. I dont know if you are getting the question or I need to express myself better. Thank you from now,
In MySQL, you can do:
update db.table
set boolean = 1
where boolean = 0
order by numberColumn
limit 1;
