Quoted strings in Oracle SQL

2nd May 2007

Here’s a gotcha that caught up with me on my journey into the world of Oracle SQL: string quoting. Anything enclosed in double-quotes (") is the name of an Oracle object (variable, table and so on) while values are enclosed in single quotes (‘). The reason that this one caught me out is that I have a preference for double quotes because of my SAS programming background; SAS macro variables resolve only when enclosed in double-quotes, hence the convention.
