Code

If you want to parse following sql
CREATE TABLE person
(
personId STRING( MAX) NOT NULL,
nickName STRING( MAX),
nickNameSearchTerm2 STRING( MAX) AS (NORMALIZE(nickName,NFD)) STORED,
) PRIMARY KEY(personId);`,

spansql.ParseDDL gives following error
got "(" while expecting ")"

You can't use ,NORMALIZE(nickName,NFD in the function code
other action succeeds well

is it possible to allow NORMALIZE in the expression
