MSSQL change column name

Hello,

to create a schema for mssql works ok, but to alter the name of a column, use the SQL command "CHANGE" and Mssql not recognize this command.
to alter the name of a column in MSSQL you should use the store procedure "sp_rename"

Do not know if I'm doing something the wrong way, but the command "php app \ console doctrine: schema: update" does not work by altering the name of the column

sorry my english it's very poor
