Impala Reserved Words
The following are the reserved words for the current release of Cloudera Impala. A reserved word is one that cannot be used directly as an identifier; you must quote it with backticks. For example, a statement CREATE TABLE select (x INT) fails, while CREATE TABLE `select` (x INT) succeeds. Impala does not reserve the names of aggregate or scalar built-in functions. (Formerly, Impala did reserve the names of some aggregate functions.)
Because different database systems have different sets of reserved words, and the reserved words change from release to release, carefully consider database, table, and column names to ensure maximum compatibility between products and versions.
