如何选择SQL列中条目的最后6位数字的最大值

Question

I am trying to select the maximum value of the last 6 digits in a list of strings

This is for creating an Inbox Query in Infor EAM

OBJ_CODE is the column and R5OBJECTS is the table. I have tried the following code but the number returned is 0.

SELECT MAX(RIGHT(OBJ_CODE,6)) FROM R5OBJECTS

My list looks like this

AAAA100000
AAAA100001
AAAA100002
AAAA100003
AAAA100004
AAAA100005
...
AAAA100999
...
BBBB100006
BBBB100007
BBBB100008
BBBB100009
BBBB100010

So the expected output would be 100999

Answer 1

It seems this table R5OBJECTS is too big, and your sql query performance didn't pass the base configuration parameter.

If using Inbox -> Set your INBXSCOR to 50 and try your query again.

If using KPI -> Set your KPISCOR to 50

SQL Statement

Enter the SQL statement to calculate the number of applicable records for the inbox entry. The system automatically populates SQL Statement Text. Note: SQL Statement cannot exceed the performance score limit defined in the INBXSCOR installation parameter.

Answer 2

尽管此代码可以在SQL Server 2016中很好地实现，但我可以添加其他功能以将string转换为int以确保：
SELECT MAX(CONVERT(INT,RIGHT(OBJ_CODE,6))) FROM R5OBJECTS
