Thread: [pgadmin-support] SQL syntax highlightning don't work for single backslash '\'
When I have somewhere in text value single backslash char, then everything behind this char will not be highlighted correct.
Simple example 1:
SELECT '\';
Simple example 2:
-- Test 1
SELECT a || '\' || b
UNION ALL
-- Test 2
SELECT c || '\' || d;
Screenshots of syntax highlighting:
Single backslash:
Dual backslash:
pgAdmin 4 v1.5
Desktop Runtime
Windows 10 x64 1511
Re: [pgadmin-support] SQL syntax highlightning don't work for single backslash '\'
UNION ALL
SELECT 'c' || E'\\' || 'd';
I reserve the right to fantasize. Whether or not you
wish to share my fantasy is entirely up to you.

Thanks for the info, I will correct my statements.
I have reported it, because syntax highlighting in pgAdmin 3 was able to show it even with single backslash and PostgreSQL returns it visually correct.
Result: solved

That is because the Backslash is an ESCAPE character, so you must ESCAPE it and use two backslashes if you want it to be interpreted
as a literal.
Also, do not forget to enclose your strings in quotes!
IE:
SELECT 'a' || E'\\' || 'b'
UNION ALL
SELECT 'c' || E'\\' || 'd';

>Unless you omit the E prefix on the string literal, which the OP did.Nope! That results in 'a//b' but the op wants 'a/b';Hence the need to Escape.
