Maciej Bryński commented on SPARK-13283:
----------------------------------------
No it's not fixed.
Problem is in:
https://github.com/apache/spark/blob/0d42292f6a2dbe626e8f6a50e6c61dd79533f235/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/jdbc/JdbcUtils.scala#L255
The trick is that different RDBMS are using different quoting sign. Most of
them are using ", but MySQL `.
So we have to add quote sign to dialect.

> Hi,
> I have following problem.
> I have DF where one of the columns has 'from' name.
> {code}
> root
> |-- from: decimal(20,0) (nullable = true)
> {code}
> When I'm saving it to MySQL database I'm getting error:
> {code}
> Py4JJavaError: An error occurred while calling o183.jdbc.
> : com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an
> error in your SQL syntax; check the manual that corresponds to your MySQL
> server version for the right syntax to use near 'from DECIMAL(20,0) , ' at
> line 1
> {code}
> I think the problem is that Spark doesn't escape column names with ` sign on
> creating table.
> {code}
> `from`
> {code}
