MSSQL Migration Error

[meladon1337]

When applying the migrations to a azure mssql Database the following migration does not work.
https://github.com/eclipse/hawkbit/blob/master/hawkbit-repository/hawkbit-repository-jpa/src/main/resources/db/migration/SQL_SERVER/V1_12_16__add_action_initiated_by___SQL_SERVER.sql

Fixed the issue with the "GO;" because it does not work in one statement:
ALTER TABLE sp_action ADD initiated_by VARCHAR(64) NOT NULL CONSTRAINT DF_SpAction_InitiatedBy DEFAULT '';
GO;
ALTER TABLE sp_action DROP CONSTRAINT DF_SpAction_InitiatedBy;
ALTER TABLE sp_target_filter_query ADD auto_assign_initiated_by VARCHAR(64);
