Why do you expect the concatenation of two characters to return a length of
one?

Hi,
In the Length () function, it will be 2 characters where you want it to be
1 character.
Is it possible to respond by changing the settings such as changing
the collation setting like SQL Server?
Also, if you understand how to deal with it (eg, create your own
function), it would be helpful if you could provide as much
information as you can.
Try char_length(text) instead.
