Bonjour,
Sorry I mistyped the version of Mysql with which we have the bug.
It's Mysql-3.23.36 with patch correcting Solaris and other non Linux
Unix problem.
> We found a bug in INNOBASE tables with col_name(length) indexes.
>
> Here is the table :
>
> create table test (
> symbole char(20) not null primary key,
> libelle char(100) not null,
> index id_lib (libelle(1))
> ) TYPE=INNOBASE;
>
>
> For the test I insert one row but there can be many, the result is
> the same :
>
> insert into test values('AAAAA','ABCDEF');
>
> I check that the row is in the table :
>
mysql>> select * from test;
> +---------+---------+
> | symbole | libelle |
> +---------+---------+
> | AAAAA | ABCDEF |
> +---------+---------+
> 1 row in set (0.00 sec)
>
> I check the indexes in the table :
>
mysql>> show index from test;
