How to copy specific columns from one table to another in Tarantool

I have 2 tables, for example:

table X, columns:
 A integer
 B string
 C number

table X2, columns:
 A integer
 C number

how to copy contents of X to X2 (excluding the missing columns) in Tarantool?

tried, but didn't work:

• INSERT INTO "X2" SELECT "A", "C" FROM "X"
• SELECT "A", "C" INTO "X2" FROM "X"

(version used: 2.6.2)

What kind of error do you get? I don't have 2.6.2 at hand, but when I try on 2.7.0 everything works just fine:

tarantool> \set language sql
tarantool> \set delimiter ;
tarantool> CREATE TABLE x (col1 INTEGER PRIMARY KEY, col2 VARCHAR(20), col3 INTEGER);
tarantool> CREATE TABLE x2 (col1 INTEGER PRIMARY KEY, col2 INTEGER);
tarantool> INSERT INTO x VALUES (1, 'a', 10), (2, 'b', 20), (3, 'c', 30);

tarantool> SELECT * FROM x;
