golang gorm Access the underlying mysql query

In the new version (GORM v2), use the Logger interface:

import "gorm.io/gorm/logger"


db, err := gorm.Open(mysql.Open(connectionDSN), &gorm.Config{
    Logger: logger.Default.LogMode(logger.Info),
})

For old version (GORM v1):

db, err:= Open(dbType, connectionDSN);
db.LogMode(true)

Note: this is not specific to MySQL and will work with any other DB driver (e.g. Postgres, SQLite, etc.).

This will do the trick:

db, err:= Open(dbType, connectionDSN);
db.LogMode(true)

You can pass your own logger to gorm using gorm.SetLogger method. It uses the Print method of the logger to print logs as well as SQL queries. The log level of Print method for any logger(logrus/go's inbuild logger) is generally set to INFO. While passing the logger to gorm, if you set the log level to anything below or equal to INFO(DEBUG/INFO) you can see the sql queries and other logs by gorm

Also you can parse the log level from a config file where you can set it based on environment
