    Description

      Currently we have two flags:

      • STRICT_TRANS_TABLES
      • STRICT_ALL_TABLES

      These flags were originally added to control how to treat warnings that happen on updating table fields for transactional and non-transactional tables.

      Gradually these flags spread all around the code to change the server behavior in contexts not directly related to tables, such as:

      • SP variables, SP routine parameters, function return values
      • Built-in SQL functions (e.g. badly formed strings)
      • Too long comments
      • Too long messages in SIGNAL
      • Duplicate values in ENUM/SET
      • Automatic VARCHAR -> BLOB conversion

      During recent discussions we agreed (Bar, Elena, Serg) that STRICT_XXX_TABLES should not affect anything when no tables are involved.

      To address this, we'll introduce a new STRICT_XXX flag that will control server behavior when no tables are involved.

      The exact flags name is a subject to discussion.
