错误代码：1054。“订单子句”中的未知列“ S.No”

Question

I am getting the below error while using the following query using "ORDER BY" Clause, S.No (int type) does exist in the table, not sure why am hitting this error? Any ideas how to fix it?

SELECT gerrit_id
FROM gerrits.gerrit_table
WHERE (((SU_version>='00.00.0001')&&(SU_version<='00.00.0006'))
    AND PL='LA.HB.1.1.1'
    AND component='SU_CNSS_BT_FM_LA.HB.1.1.1') 
ORDER BY S.No

Error:-

Error Code: 1054. Unknown column 'S.No' in 'order clause'

I'm surprised that the DBMS has accepted the column name S.No although try this:

SELECT gerrit_id
FROM gerrits.gerrit_table
WHERE (((SU_version>='00.00.0001')&&(SU_version<='00.00.0006'))
    AND PL='LA.HB.1.1.1'
    AND component='SU_CNSS_BT_FM_LA.HB.1.1.1') 
ORDER BY `S.No`
