Details
So, unfortunately, at work the other day we put a site into production after some editing/changes that still had the development database configuration. As a result, we have several records spanning across 4 tables in the development DB that need to be appended onto the production DB.
Currently I have the necessary data extracted into temporary tables on the development DB.
Table structures
All of the id's are auto-inc
t1 - Contact information - contains contact_id
t2 - Submission information - contains submission_id
t3 - Swing table - contains contact_id & submission_id
t4 - Submission attributes - contains submission_id
Possible solutions
I have tried just to simply use a query like this for each table:
insert into Production.submission (select null, col1, col2, etc from Dev.tmp_submission)
However, I quickly found that this is tedious & very error prone. Records could be inserted while I am working and I may get id's mixed up, etc..
I have thought about adding a very high number to all of the id's in the development data set such as 50000 (the highest id in production out of all of the tables is around 28000). then Just insert all of the data into production. Would MySQL figure out the auto-inc values for all of the tables if I did this or would there be a clash eventually?
Conclusion
How could I get this relational data from the development database to the production database?
Clearly, I am not the most seasoned of DB admins. Would really appreciate some answers! Please, let me know if there is any other information you might find useful.
