ColumnStore Naming Conventions

This lists the different naming conventions enforced by the column store, compared to the normal MariaDB naming conventions.

• User names: 64 characters (MariaDB has 80)

• Table and column names are restricted to alphanumeric and underscore only, i.e "A-Z a-z 0-9 _".

• The first character of all table and column names should be an ASCII letter (a-z A-Z).

• ColumnStore reserves certain words that MariaDB does not, such as SELECT, CHAR and TABLE, so even wrapped in backticks these cannot be used.

Reserved words

In addition to MariaDB Server reserved words, ColumnStore has additional reserved words that cannot be used as table names, column names or user defined variables, functions or stored procedure names.
