> Each AST statement node has a {{toSql()}} implementation. The code for {{ScalarFunction}} and ToSqlUtils has a number of issues:
>  * If Location or Symbol are not set, they are shown as {{'null'}}. Better to omit these clauses if the items are not available.
>  * The generated SQL does not follow the [Impala CREATE TABLE|] syntax. For example, the signature and return value are provided for JAVA functions, but should not be.
>  * Unlike other statements, this one is generated with a trailing newline.
>  * {{ToSql.getCreateFunctionSql()}} fails to separate functions with the semi-colon statement terminator.
