Hello. The current version of the SQL Standard is SQL:2016 plus corrigenda and additional parts from 2019. Please, don't talk about SQL-92, it is completely outdated, there are six (!) versions that were published after it.
I don't have the very recent version of ISO/IEC 9075-2, but in previous versions in section “Comparison of character strings”, comparison operations are delegated to the collation, and definition of comparison predicate talks about the same. Technically the standard still requires padding, but it should be a character that is not defined in the character set and that is smaller than any character from the character set if collation has NO PAD characteristic. Supported collations are implementation-defined in the Standard, so you can't assume that all databases will work in the same way. >From my point of view PRIMARY collation shouldn't be the default, it is too relaxed for normal use cases, it will break many applications. I already saw such problems when a custom collation were used (for non-English languages) and this strength was accidentally chosen. -- You received this message because you are subscribed to the Google Groups "H2 Database" group.
