    Description

      CREATE TABLE Employees (

      This works without check constraints and I do not see why the insert should fail. And IF, at least the error message is nonsense...
      Docu states that most deterministic functions work.

          You seem to have a typo in the constraint: CHECK (CHAR_LENGTH(FirstName > 2)). I guess you meant CHECK (CHAR_LENGTH(FirstName) > 2)

          Possibly yes. But behaviour of insert is wrong any way... IMHO

          If you mean that INSERT produces an error when you attempt to insert two rows, but only a warning when you attempt to insert one – I would agree, except that I can't reproduce it. For me, both INSERTs produce errors in strict mode and warnings in non-strict mode, quite as expected. Is it possible that you changed sql_mode between those two attempts? If not, please paste or attach your cnf file(s), or better still, unabridged output from the same client session – failed INSERT, succeeded INSERT, and the output of SHOW VARIABLES.

          No, I have NOT changed sql_mode in between.

          As you wish, madame, a complete test case:

          Thanks! Binary logging makes the difference. Maybe there is some historical reason for it, but I can't find it documented so far, so I'll assume for now it's a bug.

          create table t1 (i int, check(i>'foo'));
          insert into t1 values (1),(2);
          Got one of the listed errors
          insert into t1 values (1);
          Warnings:
          Error	1292	Truncated incorrect DOUBLE value: 'foo'
          drop table t1;
          

          Without binary logging, both INSERTs fail (in strict mode).

          The error text is correct as it comes from wrong usage of CHAR_LENGTH()

          Problem was that verify_constraints() didn't check if
          there was an error as part of evaluating constraints (can
          happen in strict mode).

          In one-row-insert the error was ignored when using binary logging as
          binary logging clear errors if insert succeeded. In multi-row-insert
          the error was noticed for the second row.

          After this fix one will get an error for both one and
          multi-row inserts if the constraints generates a warning
          in strict mode.
