Hye everybody,

I have a data REGCOUNT_T
--------------------------
1
10
2
3
4
5
6
7
8
9

This is my SQL command:
SELECT MAX(REGCOUNT_T) AS RUNCOUNT FROM FEEDBACK_DATA

After next execution, I still get 9 as the max value. How to get the 10 value so that the next running count will be 11 after I add by 1?

Solution 1

The reason is that the data of REGCOUNT_T column may be in text type, in which case 10 comes before 9, so 9 is returned as maximum value.
To get the correct result either convert the value of REGCOUNT_T to numeric type as below

SQL

SELECT MAX(CONVERT(INT,REGCOUNT_T)) AS RUNCOUNT FROM FEEDBACK_DATA

or set the data type REGCOUNT_T to a numeric type like INT.
