--------------------------------------
Summary: Add quoting rules to SQL guide
Key: SPARK-24125
URL: https://issues.apache.org/jira/browse/SPARK-24125
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.4.0
Reporter: Henry Robinson
As far as I can tell, Spark SQL's quoting rules are as follows:
* {{`foo bar`}} is an identifier
* {{'foo bar'}} is a string literal
* {{"foo bar"}} is a string literal
The last of these is non-standard (usually {{"foo bar"}} is an identifier), and
so it's probably worth mentioning these rules in the 'reference' section of the
[SQL
guide|http://spark.apache.org/docs/latest/sql-programming-guide.html#reference].
I'm assuming there's not a lot of enthusiasm to change the quoting rules, given
it would be a breaking change, and that backticks work just fine as an
alternative.
