Get the minimum value from 2 columns
Suppose we have a table:
CREATE TABLE Table (
Code varchar(10),
Value int);
And we need to select the min of Value in relation to Code.
For example, if the table is:
Code Value
A 20
A 15
A 10
B 20
B 10
B 20
C 10
C 30
We need to get A and B (because their value is minimum).
My question is: what is the best solution for SQL?
I was thinking something like this:
SELECT Code, Value
FROM Table
WHERE Value=(
SELECT MIN(Value)
FROM Table
WHERE Code=Value)
But it seems that I am not using the right approach, so I am thinking to add an index to the column Code, so I can do this:
SELECT Code, Value
FROM Table
WHERE Value=(
SELECT MIN(Value)
FROM Table
WHERE Code=Value)
What is the best way to solve this problem?
A:
The right approach is to not write your own query. The optimizer is probably not going to do a good job, and this is probably going to be a bottleneck, which means that there are probably going to be a lot of scans of the index, leading to quite high response time. ac619d1d87
