Halfwidth and fullwidth Interchange

Due to the restrictions on Field Types in some databases corresponding to txtbox, sometimes when full-angle characters are written in, a problem may occur during statistics query.

It is better to switch. You can choose to convert the full angle into a half angle before saving it, And then store it in, so there will be no problem during statistics. 1 Halfwidth Interchange # Region Halfwidth Interchange
