php - How to compare to MySQL tables and display the differences? -

-

We get a daily feed that is used to populate a MySQL database. I want to see the new feed to compare to the previous one, what has changed, added or removed. I am working in MySQL and PHP How can it be best done in MySQL? I am thinking that it should take the previous feed which is a MySQL table and compare it to a new feed which is also stored as a MySQL table. But how can I do this so that it can achieve the rows that have not been found in the new MySQL table? Thanks!

This can help you: 

  SELECT a. * Is not WHERE ROW (a.col1, a.col2, รข ?? |) with `OLD_TABLE_NAME` (SELECT * FROM NEW_TABLE_NAME) UNION ALL SELECT b. * FROM * NEW_TABLE_NAME`b WHERE ROW (BOO1, BOO2, a ??) No (SELECT * FROM OLD_TABLE_NAME)   
 Enjoy!

I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
