• Fix Build Number:

  8.4.1.2212

1Create one table
create table a2 (i int);
2 Click edit table
add column j int, m int.
3 then change j to k
4 Click save

It will pop "cannot found k"

Additional:
Because the sql is as follows:
CREATE TABLE "a2"(
"i" integer
);

ALTER TABLE "a2" ADD COLUMN "m" integer AFTER "k";
ALTER TABLE "a2" ADD COLUMN "k" integer AFTER "i";
