This topic introduces all reserved words and keywords in MaxCompute SQL.

Notice
  • When you name a table, a column, or a partition, do not use reserved words or keywords. Otherwise, an error may occur.
  • Reserved words are not case-sensitive.
  • If you use keywords to name a table, a column, or a partition, you must escape the keywords by using double quotation marks ("). Otherwise, an error is returned.
