设置多个日期范围的多个总和

Question

Here is the query I am trying to complete.

SELECT salesrep, 
    SUM(lines_total) AS OTSUM,
    SUM(order_type = 'NEW') OTNEW,
    SUM(order_type = 'REPEAT') OTREPEAT,
    SUM(lines_total 
      WHERE order_closed BETWEEN '2020-11-01' AND '2020-11-30') AS OTLMSUM
    SUM(lines_total 
      WHERE order_closed BETWEEN '2020-12-01' AND '2020-12-31') AS OTTMSUM
FROM `ranger_orders`
WHERE order_closed BETWEEN '2020-01-01' AND '2020-12-31'

Of course this fails, but how do I setup the SUMS for multiple date ranges, the WHERE date range at the end needs to stay as is.

For these lines:

SUM(lines_total WHERE order_closed BETWEEN '2020-11-01' AND '2020-11-30') AS OTLMSUM
SUM(lines_total WHERE order_closed BETWEEN '2020-12-01' AND '2020-12-31') AS OTTMSUM

Answer 1

You need CASE expressions for conditional aggregation, like:

SUM(CASE WHEN order_closed BETWEEN '2020-12-01' AND '2020-12-31' THEN lines_total ELSE 0 END) AS OTTMSUM

For each of the sums, change BETWEEN '2020-12-01' AND '2020-12-31' accordingly.

Answer 2

To keep the data aligned on rows by salesrep, then you still need to add all the numbers - but you can substitute with zeroes where they are out of range....

SUM(IF (order_closed BETWEEN '2020-11-01' AND '2020-11-30', lines_total, 0)) AS OTLMSUM

You pointed out that you get a syntax error, but this looks like a semantic error:

SUM(order_type = 'NEW') OTNEW

Are you really trying to add these up? Count them? Classify them?

Query might be something like...

SELECT salesrep, 
    SUM(lines_total) AS OTSUM,
    SUM(IF(order_type = 'NEW', 1, 0)) OTNEW,
    SUM(IF(order_type = 'REPEAT', 1, 0)) OTREPEAT,
    SUM(IF (order_closed BETWEEN '2020-11-01' AND '2020-11-30', lines_total, 0)) AS OTLMSUM
    SUM(if(order_closed BETWEEN '2020-12-01' AND '2020-12-31', lines_total, 0)) AS OTTMSUM
FROM `ranger_orders`
WHERE order_closed BETWEEN '2020-01-01' AND '2020-12-31'

Also, with aggregate queries (SUM, AVERAGE, COUNT...) you should have a GROUP BY clause....

GROUP BY salesrep 

However wouldn't it have been simpler to do this....

SELECT salesrep, 
    SUM(lines_total) AS OTSUM,
    SUM(IF(order_type = 'NEW', 1, 0)) AS OTNEW,
    SUM(IF(order_type = 'REPEAT', 1, 0)) AS OTREPEAT,
    DATE_FORMAT(order_closed, '%Y-%m') AS month,
    SUM(lines_total) AS otsum
FROM `ranger_orders`
WHERE order_closed BETWEEN '2020-01-01' AND '2020-12-31'
GROUP BY salesrep, DATE_FORMAT(order_closed, '%Y-%m')
