I’m writing a PHP script to generate SQL dumps from my database for version control purposes. It already dumps the data structure by means of running the appropriate SHOW CREATE .... query. Now I want to dump data itself but I’m unsure about the best method. My requirements are:
- I need a record per row
- Rows must be sorted by primary key
- SQL must be valid and exact no matter the data type (integers, strings, binary data…)
- Dumps should be identical when data has not changed
I can detect and run mysqldump as external command but that adds an extra system requirement and I need to parse the output in order to remove headers and footers with dump information I don’t need (such as server version or dump date). I’d love to keep my script as simple as I can so it can be hold in an standalone file.
What are my alternatives?
I think the mysqldump output parsing is still the easiest. I think there are really few meta-data you have to exclude, and thus dropping those should be only a few lines of code.
You could also look at the following mysqdump options: –tab, –compact
