Thanks @dantengsky for adding the 'query' field in the sql parser. It is very helpful!

look great to me, thanks @junli1026 !

@BohuTANG

do we need to clarify(in doc) that the "append columns" semantic of MySQL CTAS are not supported(by design) in our impl?

from https://dev.mysql.com/doc/refman/8.0/en/create-table-select.html,

Notice that the columns from the SELECT statement are appended to the right side of the table, not overlapped onto it. Take the following example

mysql> SELECT * FROM foo;
+---+
| n |
+---+
| 1 |
+---+

mysql> CREATE TABLE bar (m INT) SELECT n FROM foo;
Query OK, 1 row affected (0.02 sec)
Records: 1  Duplicates: 0  Warnings: 0

mysql> SELECT * FROM bar;
+------+---+
| m    | n |
+------+---+
| NULL | 1 |
+------+---+
1 row in set (0.00 sec)

personally, I never used this feature of MySQL. not mention this in the doc is ok for me.

Yes, it is! but it is contributed by @AngleNet in PR #3356, thanks @AngleNet !

[BohuTANG]

Looks great 👍
Do you have the plan change this test to

CREATE TABLE db1.test1(a INT, b INT) ENGINE=MEMORY;

... ...

CREATE TABLE db2.test3(x Varchar, y Varchar) ENGINE=FUSE AS SELECT * FROM db1.test1;
... ...

🤔
