Laravel Eloquent drop/rename column, rerun migration, MSSQL default value issue

MSSQL default value of a column issue:

If a column in MSSQL server has a default value, it has a default constraint.
The constraint must be dropped , before the column can be dropped

for example :

alter table CompanyTransactions drop constraint [df__CompanyTr__Creat__0cdae408];

alter table CompanyTransactions drop column [Created];

How to use Laravel to drop a column in MSSQL with default value ?
1. php artisan make:migration drop_column_to_my_table
2.    public function up()
    {
        Schema::table('my_table', function (Blueprint $table) {
            //
            $table->dropColumn('my_cloumn');
        });
    }
run the migration
php artisan migrate --path=/database/migrations/<file_name>
Exception will thrown indicating the column has a constraint(default value constraint in MSSQL)
goto MSSQL manager , drop constraint <contraint_name>
run migration again

La-ravel Eloquent re run already executed migration:
php artisan migrate --path=/database/migrations/migration_file_name.php
if the application indicates migration already ran.
Go to your DB(ex SQL server), find migrations table, delete the already executed migration record
Then re run php artisan migrate --path=/database/migrations/migration_file_name.php
If encountered unable to drop column with default value issue, run the SQL command drop the default value constraint and then re run the drop column migration
