内部连接基于一个表中的两列和另一列中的一列的2个表

Question

I have two tables I am wanting to inner join. The column of one is Ordind000.PROCPLANID . This has the job, the J000012345 , and suffix, the .00001 both in this one column. But in the Job table that I need to join it to, both the job and the suffix are separate columns.

My guess is I need to use the replace command and write it to a temp table, but I am hoping for a much easier solution. I will also need to strip the decimal at the beginning of the job and suffix numbers in the PROCPLANID columns I think.

Answer 1

There are a lot of ways you could manipulate this, here is one:

SELECT columns
FROM table1 t1
INNER JOIN table2 t2 on 
SUBSTRING(t1.procplanid,2,10) + RIGHT(t1.procplanid,1) = t2.job + t2.suffix

This will compare the job portion of procplanid (without the decimal) + the last digit of procplanid as the suffix , to job + suffix

Highlighted examples in the image will become:

• J0000784749: Job = J000078474, Suffix = 9
• J0000760622: Job = J000076062, Suffix = 2
