Hello
I found BNF for SQL 2003 and I found there some small difference.
Standard use keyword ESCAPE, but PostgreSQL use keybord UESCAPE.
Anybody knows reason?
<Unicode character string literal> ::=
[ <introducer> <character set specification> ]
U <ampersand> <quote> [ <Unicode representation> ... ] <quote>
[ { <separator> <quote> [ <Unicode representation> ... ] <quote> }... ]
[ ESCAPE <escape character> ]
thank you
Pavel Stehule
