Which SQL flavor does Spark SQL follow?

[Aakash Basu <aa...@gmail.com>]

Hi,

Wish to know, which type of SQL syntax is followed when we write a plain
SQL query inside spark.sql? Is it MySQL or PGSQL? I know it isn't SQL
Server or Oracle as while migrating, had to convert a lot of SQL functions.

Also if you can provide a documentation which clearly says the above would
help.

Thanks,
AB

it closely follows Hive sql.

from the analytical functions its is similar to Oracle. Anyway if you know
good SQL as opposed to Java programmer turned to SQL writer you should be
OK.
