SqlVisual is currently based on the syntax of Apache Spark and Apache Hive. For detailed syntax information, please check the documentation . We have plans to support ANSI SQL in the near future, as well as expand to other SQL dialects including Snowflake, BigQuery, PostgreSQL, and more.
We typically use single quotes or double quotes to enclose string literals. For example, 'John' or "Smith". However, when dealing with identifiers, such as table or column names, we don't use any quotes. If an identifier contains special characters, we can use backticks (`) to escape them in sqlvisual.
