Creating a New MySQL Database with go-sql-driver

In Go, the go-sql-driver package offers a robust way to connect to MySQL databases. However, one common challenge is creating a new database when the connection scheme requires an existing database name.

Can go-sql-driver Create New Databases?

Yes, go-sql-driver can be used to create new MySQL databases. You will need to connect as a MySQL user with the necessary privileges to create new databases.

How to Create a New Database with go-sql-driver:

1. Establish a connection to the MySQL server using a user with CREATE DATABASE privileges.

db, err := sql.Open("mysql", "admin:admin@tcp(127.0.0.1:3306)/")
if err != nil {
    panic(err)
}
defer db.Close()

2. Create the new database using the CREATE DATABASE command.

_,err = db.Exec("CREATE DATABASE "+databaseName)
if err != nil {
    panic(err)
}

3. Switch to the newly created database using the USE command.

_,err = db.Exec("USE "+databaseName)
if err != nil {
    panic(err)
}

4. Create any necessary tables or perform other database operations as desired.

// For example, create a table named 'example' in the new database
_,err = db.Exec("CREATE TABLE example ( id integer, data varchar(32) )")
if err != nil {
    panic(err)
}

Important Notes:

• The database name is not specified in the connection string initially.
• The connection is switched to the newly created database after its creation.
• Refer to the VividCortex documentation for detailed information on using the database/sql package: http://go-database-sql.org/index.html
