Support MySQL or MariaDB for github.com/gopsql/psql.
You can make MySQL SELECT, INSERT, UPDATE, DELETE statements with this package.
NOTE: Please don't use those features that are only available in PostgreSQL but not MySQL at the moment.
Example
package main

"fmt"
"strconv"
"time"
"github.com/gopsql/logger"
"github.com/gopsql/mysql"

)
type (
User struct {
// using a different table name other than "users"
__TABLE_NAME__ string "user"
Id int
Name string
Avatar string
Phone *string // can be null
CreatedAt timestamp // use integer to store time
UpdatedAt timestamp
}
)
var (
