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.
