Selecting from multiple tables based on conditions
I have the following code where I am pulling all data from one table, a. Then counting a column from a different table as a new column. However, I am getting a syntax error message. Can someone point me in the right direction?
select a.*
,(Select count(DISTINCT b.Employee) as `Number of Distro`
from `transform_data_9` b
where Date_Format(a.date,'%Y-%m-%d') = b.`date` and a.date between b.`End Time` - b.`Start Time` and b.`department` = 'Distro')
from `transform_data_8` a

You need to give a name to the new calculated column, like so:
select a.*
,(Select count(DISTINCT b.Employee)
from `transform_data_9` b
where Date_Format(a.date,'%Y-%m-%d') = b.`date` and a.date between b.`End Time` - b.`Start Time` and b.`department` = 'Distro') AS `Number of Distro`
from `transform_data_8` aLet me know if you still have any issues,
