SQL Guide : Using SQL for database administration : Using solidDB® SQL syntax : Scalar functions
  
Scalar functions
The solidDB® server supports the use of direct function names.
For example:
SELECT substring(line, 1,4) FROM test;
However, functions whose names match reserved words must be enclosed with escape characters (double quotation marks). For example:
SELECT "left"(line,4) FROM test;
or:
SELECT {fn left(line,4)} FROM test;
The latter example corresponds to the ODBC implementation-independent syntax. It can be used in all interfaces.
