psql恢复sql转储语法错误

Question

I am trying to import https://www.yelp.com/dataset/documentation/sql into a PostgreSQL instance. It is having problems with accent marks/backtick. Other than doing a character replace, is there any other way to deal with this?

Answer 1

These are typical MySQL syntax issues that PostgreSQL conforms to the standard on and therefore doesn't support. There are a few different converters on GitHub that might help. When I had to do this last, there were tools to convert text dumps. They didn't work perfectly but they got things close enough. Reviewing the tools around today, they tend to assume you have an actual MySQL database, not just a dump file.

So it looks like the appropriate way to address this today is to load the data into MySQL and then move it to PostgreSQL. In this regard you seem to have four options that I can think of for converting the schema and data:

1. There are tools to convert XML dumps from MySQL and load these into PostgreSQL.
2. You could set up a foreign data wrapper from PostgreSQL to the MySQL db and then copy the schemas and data in.
3. You could manually convert the schemas, and then dump/reload the data using an ETL process via CSV.
4. There are tools to read a live MySQL database and insert the data into PostgreSQL.
