Keywords

This topic describes non-reserved keywords and reserved keywords. It provides a list of reserved keywords in StarRocks.

Introduction​

Keywords in SQL statements, such as CREATE and DROP, have special meanings when parsed by StarRocks. Keywords are classified into non-reserved keywords and reserved keywords.

  • Non-reserved keywords can be directly used as identifiers without special treatment, such as table names and column names. For example, DB is a non-reserved keyword. You can create a database named DB.

    CREATE DATABASE DB;
    Query OK, 0 rows affected (0.00 sec)

  • Reserved keywords can be used as identifiers only after special treatment. For example, LIKE is a reserved keyword. If you want to use it to identify a database, enclose it in a pair of backticks (\).

    CREATE DATABASE `LIKE`;
    Query OK, 0 rows affected (0.01 sec)

    If it is not enclosed in backticks (\), an error is returned:

    CREATE DATABASE LIKE;
    ERROR 1064 (HY000): Getting syntax error at line 1, column 16. Detail message: Unexpected input 'like', the most similar input is {a legal identifier}.
