> Array construction DML's don't currently work as expected.
> Initially it seemed like a type matching issue, but once I forced the correct types,
the validator still throws exceptions.
> Example input query:
> {code}String ddl = "CREATE TABLE " + tableName + " (region_name VARCHAR PRIMARY KEY,varchars
CHAR(5)[],integers INTEGER[],doubles DOUBLE[],bigints BIGINT[],chars CHAR(15)[],double1 DOUBLE,char1
CHAR(17),nullcheck INTEGER,chars2 CHAR(15)[])";
> String dml = "UPSERT INTO " + tableName + "(region_name,varchars,integers,doubles,bigints,chars,double1,char1,nullcheck,chars2)
VALUES('SF Bay Area'," +
>                 "ARRAY['2345','46345','23234']," +
>                 "ARRAY[2345,46345,23234,456]," +
>                 "ARRAY[23.45,46.345,23.234,45.6,5.78]," +
>                 "ARRAY[12,34,56,78,910]," +
>                 "ARRAY['a','bbbb','c','ddd','e']," +
>                 "23.45," +
>                 "'wert'," +
>                 "NULL," +
>                 "ARRAY['a','bbbb','c','ddd','e','foo']" +
>                 ")";
