I had a developer create some code for me and he has used angled single quotes throughout the SQL statements. I have never used these before and was hoping someone could explain the difference between angled and straight?
If I replace all angled with straight quotes the queries dont work.
Angled quotes (`, actually called backticks) are used to delimit identifiers, e.g. fields and table names. Straight quotes are used to delimit strings, e.g. 'Hello, world!'. You can't mix the two.
