Hi all;


I have a table that includes a varchar column.

I am inserting some data and one of the strings = "Poker 5 card Hold'Em"

as a straight string it errors out.


I tried this :  quote_ident ( 'Poker 5 card Hold'Em')

but it still error's out


I also tried :  quote_literal('Poker 5 card Hold\'Em')

but it also errors out:


psql:test.sql:1042: ERROR:  syntax error at or near "Em"
LINE 1: ...ed) VALUES ( quote_literal('Poker 5 card Hold\\'Em'), 2, 1...


Thanks in advance

correction, the quote_ident below should be quote_literal

I did not try quote_ident

You have the right idea you need to escape it.  But guessing isn’t a good method to figure out how.


You can’t use quote_* on a literal if you do not express the literal correctly.

Unbalanced single quote, try dollar quotes as a general get out of jail approach…

pendari=# SELECT $x$Poker 5 card Hold'Em$x$::TEXT;        text
---------------------- Poker 5 card Hold'Em
(1 row)
