Hi,
I have an index with expression characterField + DateTimeField.
How should the expression in SQL statement?
Currently, I am using the expression below. But I am not sure if it is optimized.
characterField + Convert(char(10), DateTimeField, 112)
Any ideas?
I am not the most powerful man in this world.
I am not the worst man in this world either.
I just as same as all of you.
I still need to learn from my mistakes...
