MySQL Bugs: #91893: LOAD DATA INFILE throws error with NOT NULL column defined via SET

Bug #91893	LOAD DATA INFILE throws error with NOT NULL column defined via SET

Description:
I have a table with a geometry column (geom POINT NOT NULL SRID 32631), and two numeric columns (x double DEFAULT NULL, y double DEFAULT NULL).

In MySQL 5.7, I used LOAD DATA INFILE to populate the table from a file containing only x and y values, with this command :

LOAD DATA INFILE 'file.csv' INTO TABLE foo
(@x, @y)
SET x = @x, y = @y, geom = POINT(@x, @y);

This worked fine, but it does not work anymore in 8.0.12.
The command immediately throws an error 

How to repeat:
Create a texte '1.txt' file containing two numeric column values. (i.e 1234\t6545)
Then :
CREATE TABLE foo (x double, y double, geom POINT NOT NULL SRID 32631);
LOAD DATA INFILE '1.txt' 
INTO TABLE foo
(@x, @y) SET x = @x, y = @y, geom = Point(@x, @y);

-> ERROR 1364 (HY000): Field 'geom' doesn't have a default value

Thank you for the bug report. Which 5.7 version it worked for you?

Thanks.

Hi. This will not work because SRID support was added in 8.0, but the same command should work without the "SRID 32631" in the column definition in 5.7, and fail in 8.0.
I can tell you which 5.7 version tomorrow.
Thanks for looking into this !

Thank you for the feedback. Are you able to insert that row (with same data of the file) using the mysql client, please print here. Thanks in advance.

Yes, I can insert without any problem. It's only the LOAD DATA INFILE that fails.

mysql> insert into foo (x,y,geom) SELECT 1, 1, ST_SRID(Point(1, 1), 32631);
Query OK, 1 row affected (0.01 sec)
Records: 1  Duplicates: 0  Warnings: 0

Just so that you have a valid test case :

mysql> CREATE TABLE foo (x double, y double, geom POINT NOT NULL);
Query OK, 0 rows affected (0.03 sec)

mysql> LOAD DATA INFILE '1.txt'
    -> INTO TABLE foo
    -> (@x, @y) SET x = @x, y = @y, geom = Point(@x, @y);
ERROR 1364 (HY000): Field 'geom' doesn't have a default value

mysql> INSERT INTO foo (x, y, geom) VALUES (1, 1, Point(1, 1));
Query OK, 1 row affected (0.00 sec)

Well, according to this page : https://dev.mysql.com/doc/refman/8.0/en/data-type-defaults.html
we will be able to set a default value for types BLOB, TEXT, GEOMETRY, and JSON.
So, this would definitively fix my problem, but when will 8.0.13 be released ?
I am in a quite desperate need for a fix to this problem.

Thanks !

Thank you for the feedback. Verified as described.

Fixed in 8.0.18.

The SET clause for LOAD DATA did not work to set GEOMETRY NOT NULL
columns.
