Hi-
I’m trying to submit a query through active record, and when I watch
the development log to see what is getting passed in, I see something
like this:
SELECT * FROM “my_model” WHERE (some_name LIKE E’%search%’)
Is the “E” character supposed to be there? I am not getting results
returned and I don’t know where that is coming from. Any ideas?
Thanks!

Are you using PostgreSQL? If so…
http://www.postgresql.org/docs/current/static/sql-syntax-lexical.html
PostgreSQL also accepts “escape” string constants, which are an
extension to the SQL standard. An escape string constant is specified
by writing the letter E (upper or lower case) just before the opening
single quote, e.g. E’foo’. (When continuing an escape string constant
across lines, write E only before the first opening quote.) Within an
escape string, a backslash character () begins a C-like backslash
escape sequence, in which the combination of backslash and following
character(s) represents a special byte value. \b is a backspace, \f is
a form feed, \n is a newline, \r is a carriage return, \t is a tab.
Also supported are \digits, where digits represents an octal byte
value, and \xhexdigits, where hexdigits represents a hexadecimal byte
value. (It is your responsibility that the byte sequences you create
are valid characters in the server character set encoding.) Any other
character following a backslash is taken literally. Thus, to include a
backslash character, write two backslashes (\). Also, a single quote
can be included in an escape string by writing ', in addition to the
normal way of ‘’.
