Re: create table named 2E9

[Rick James]

It's called "scientific notation":

mysql> SELECT 2E9;
+------------+
| 2E9        |
+------------+
| 2000000000 |
+------------+

mysql> SELECT 2a9;
ERROR 1054 (42S22): Unknown column '2a9' in 'field list'

Use backtics around your unconventional table names.
