Can you please provide some solution if you have or else it would be helpful if you could give other way to install pymssql in centos7

Answer 1

File sqlfront.h is provided by freetds-devel. Ensure this is installed

yum install freetds-devel

Now... verify that the file exists. For CentOS Linux release 7.1.1503, this was here:

ls -l /usr/include/sqlfront.h

Once found, set C_INCLUDE_PATH so pip / gcc can locate it:

export C_INCLUDE_PATH=/usr/include

now re-run pip...

Answer 2

You need to install freetds-devel (yum install freetds-devel), most likely available in EPEL.
