Mysql Command line Parameter passing to sql file

In windows mysql(5.7 version), I want to run mysql commmand using command line for .sql file as input . Also i was to pass some variable whose value should get used in .sql file. somehow I am not able to achieve it. mysql -u root -p xyz -e "set @tmp='abc'; source d:/v_test1.sql" Here I want to file v_test1.sql having mysql code and also variable @tmp being used in v_test1.sql. But getting error: > MySQL Error: Unknown column '@tmp' in 'field list' I think issue might be because of version. Please suggest some solution.
