When no existing Users table, Gorm works without any error. But I would like to keep existing data in my table tho.

I am not sure what causing Gorm to generate the invalid syntax like that. The existing Users table only have a few data in it.

Please help!

NVM, I just figured it out. I have a confict column name. Gorm is generating "user_first_name " column, but my existing table has "user_firstname ".

Added gorm:"column:user_firstname" tag!
