I'm trying to run a laravel migration that renames a particular column in my database but I repeatedly get an error message.

```
class ModifyColumnName extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::table('posts', function (Blueprint $table) {
            $table->renameColumn("content-description", "content_description");
        });
    }

}

```

I keep on getting this error message.

```
Illuminate\Database\QueryException: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; 
check the manual that corresponds to your MariaDB server version for the right syntax to use near '-description content_description VARCHAR(255) DEFAULT NULL' at line 1 (SQL: ALTER TABLE posts CHANGE content-description content_description VARCHAR(255) DEFAULT NULL)
