Description
Hello,
Can't find in documentation why it behaving like in the following test case.
create table t1 ( c1 varchar(10), c2 varchar(10), c3 int ); |
insert into t1 values ("a" , "b", 1), ("a" , "b", 2); |
create table t2 like t1 ; |
alter table t2 add column c4 bigint unsigned as (CONV(LEFT(MD5(concat(c1,c2,c3)), 16), 16, 10)) persistent unique key; |
select * into outfile 't1.csv' from t1; |
load data infile 't1.csv' into table t2 ; |
select * from t2; |
select "Wrong c4"; |
 |
insert into t2 (c1,c2,c3) values ("a" , "b", 4); |
select * from t2; |
select "correct c4"; |
a b 1 NULL
|
a b 2 NULL
|
a b 4 15541743660496249717
|
Also seeing [GENERATED ALWAYS] in documentation but can't see any description of such keyword .
Thanks
