MySQL to SQL Server - Unixtime being major problem
You mentioned Unixtime being major problem

Please note how FROM_UNIXTIME() is being used

FROM_UNIXTIME((spre.CREATEDTIME/1000)) "criacao da pesquisa",


From this line, here is what I can tell:


spre.CREATEDTIME is number of milliseconds since 1970-01-01 00:00:00 UTC
FROM_UNIXTIME() requires the number of seconds, not milliseconds
spre.CREATEDTIME has to be divided by 1000 before calling FROM_UNIXTIME()


Based on someone else's post in StackOverflow (Truncate Datetime to Second (Remove Milliseconds) in T-SQL), you will have to change it to something like:

CONVERT(datetime,char(19),spre.CREATEDTIME/1000,126) "criacao da pesquisa",


Please read T-SQL Documentation on CONVERT


  what is this # in front of some sentences??


The # character as the first character makes that whole line a comment

When you execute this script, only the first SELECT is executed

The other SELECT queries and the one UPDATE query are not executed

The first query has comments as well. If you ignore those two lines, this is what really runs:

 SELECT wo.WORKORDERID,
dpt.DEPTNAME "Department",
aau.USER_ID,
aau.FIRST_NAME "Requester", 
sadt.RATING "Rating Value", 
spre.COMMENTS "Comments",
    FROM_UNIXTIME((spre.CREATEDTIME/1000)) "criacao da pesquisa",
            MONTH(FROM_UNIXTIME((spre.CREATEDTIME)/1000)) "Mes Pesquisa",
            YEAR(FROM_UNIXTIME((spre.CREATEDTIME)/1000)) "Ano Pesquisa",
aau1.FIRST_NAME "Technician"

    WHERE (spre.CREATEDTIME &gt;= UNIX_TIMESTAMP('2014-04-01 00:00:00')*1000) AND (spre.CREATEDTIME &lt;= UNIX_TIMESTAMP('2014-08-31 23:59:59')*1000)
AND aau.FIRST_NAME LIKE '%Pumputis%'
        ORDER BY spre.CREATEDTIME
