Hmm I see the description like the following in SQL99 though I
don't understand the meaning.
i) If <escape character> is not specified, then the collating sequence used for the <like predicate> is determined by
Table3, ‘‘Collating sequence usage for comparisons’’, taking <character match value> as comparand 1 (one) and
<characterpattern> as comparand 2.
