Join Bill Weinman for an in-depth discussion in this video Concatenating strings, part of PostgreSQL 9 with PHP Essential Training.
Postgres has a few standard ways to concatenate strings.…The most common is using the Concatenation Operator which is standard SQL,…actually most of this is standard SQL.…And so you can take two strings, 'This is a string' and use the SQL…Concatenation operator which for people who are familiar with other languages…it might look strange.…It's two vertical bars which means other things in other languages.…And I will type another strings 'This is another string' and we are putting a…semicolon and these two strings get concatenated and you notice that there is no…space in between, no nothing in between.…
Of course instead of using the Concatenation operator you can use the…Concatenation function and it's simply spelled CONCAT and then instead of that…operator you use a comma and put a closing parentheses at the end.…And the result is exactly the same.…Now if you want to take several strings and have some kind of a separator in…between them, you can use concatenate with separator which is spelled like this…
