I sometimes see in a select query a where-clause like this :
where col_name = N’text’
What does this N mean?
I know that in T-SQL, it is a Unicode parsing character, but what does it mean for Oracle?
Is it the same?
How does it affect the performance of a query?
Like, if I use it on a CHAR-column, what’s the loss or profit (I doubt it) of the N-character?
I’ve searched a lot on google, but only found it for T-SQL, not for oracle.
Thanks for helping me out.
It’s a Unicode literal. See the documentation here.
I suppose one could write a test script to see how this function affects a query in their own environment.
