How to use newline character
in PostgreSQL
?
This is an incorrect script from my experiment:
select 'test line 1'||'\n'||'test line 2';
I want the sql editor
display this result from my script above:
test line 1
test line 2
But unfortunately I just get this result from my script when I run it in sql editor:
test line 1 test line 2
The backslash has no special meaning in SQL, so '\n'
is a backslash followed by the character n
To use "escape sequences" in a string literal you need to use an "extended" constant:
select 'test line 1'||E'\n'||'test line 2';
Another option is to use the chr()
function:
select 'test line 1'||chr(10)||'test line 2';
Or simply put the newline in the string constant:
select 'test line 1
test line 2';
Whether or not this is actually displayed as two lines in your SQL client, depends on your SQL client.
