> SQL: Inconsistent behavior of LENGTH limit for CHAR data type
> -------------------------------------------------------------
>
> Key: IGNITE-18492
> URL: https://issues.apache.org/jira/browse/IGNITE-18492
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Affects Versions: 3.0.0-beta1
> Reporter: Andrey Khitrin
> Assignee: Evgeny Stanilovsky
> Priority: Major
> Labels: ignite-3, sql
> Time Spent: 10m
> Remaining Estimate: 0h

> When I create a table with {{CHAR(length)}} column, it's still possible to
> insert character values with length greater than given limit.
> {code:sql}
> sql-cli> create table xx (pk int primary key, f1 char(5));
> Updated 0 rows.
> sql-cli> insert into xx values (1, 'abcdefgh');
> Updated 1 rows.
> sql-cli> select * from xx;
> ╔════╤══════════╗
> ║ PK │ F1 ║
> ╠════╪══════════╣
> ║ 1 │ abcdefgh ║
> ╚════╧══════════╝
> {code}
> In other hand, length limit is applied when I insert non-char value that's
> casted into {{CHAR}} implicitly. With the same table as above:
> {code:sql}
> sql-cli> insert into xx values (2, 1234567);
> Updated 1 rows.
> sql-cli> select * from xx;
> ╔════╤══════════╗
> ║ PK │ F1 ║
> ╠════╪══════════╣
> ║ 2 │ 12345 ║
> ╟────┼──────────╢
> ║ 1 │ abcdefgh ║
> ╚════╧══════════╝
> {code}
> Behavior should be consistent: ether strip both values down to the given
> length limit, or deny to insert too long values in both cases (like it's done
> in other DBs, like postgresql).
