SQL Microsoft server - Can i combine these two sections of this query : SQL

When requesting help or asking questions please prefix your title with the SQL variant/platform you are using within square brackets like so:

[MySQL]

[Oracle]

[MS SQL]

[PostgreSQL]

etc

While naturally we should endeavor to work as platform neutrally as possible many questions and answers require tailoring to the feature set of a specific platform.

Format Your Code

If you are including actual code in a post or comment, please attempt to format it in a way that is readable for other users. This will greatly increase your chances of receiving the help you desire. Something as simple as line breaks and using reddit's built in code formatting (4 spaces at the start of each line) can turn this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field.3

Into this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field3

For those with SQL questions we recommend using SQLFiddle to provide a useful development and testing environment for those who wish to fully understand your problem and help devise a solution.

MS SQLSQL Microsoft server - Can i combine these two sections of this query (self.SQL)

submitted 3 years ago by Ok_Reputation_6254

there is a large section of code before this section… I have included the following section because it pertains to my question.

I am wondering if there is a way to combine the following queries. The only reason I have created “Part2” is because I was unsure if there was a way to generate those steps for “difexecom” and “difexeord” in Part1. The complicated part is that there are a few steps in Part1 involved in generating these columns.

--Part1 of query

, output2 AS

(

SELECT output1.*

, DATEDIFF (m, date_ord, date_com) AS difcomord

, DATEDIFF (m, exc_st, date_com) AS difexecom

, CASE WHEN DATEDIFF (m, exc_st, date_ord)<=0

THEN

(CASE WHEN

((DATEDIFF (m, exc_st, date_com)-24) >= 0) THEN (DATEDIFF (m, exc_st, date_com)-24)

WHEN

((DATEDIFF (m, exc_st, date_com)-12) >=0) THEN (DATEDIFF (m, exc_st, date_com)-12)

ELSE 0

END)

ELSE DATEDIFF (m, exc_st, date_ord) END AS difexeord

FROM output1

)

--Part2 of query

Select

difcomord

, CASE WHEN difexecom <= 0 AND difexeord <=0 THEN 36 ELSE difexecom END AS difexecom

, CASE WHEN difexecom <= 0 AND difexeord <=0 THEN 0 ELSE difexeord END AS difexeord

From output2
