I have a brief query about the data types, according to the documentation [1]http://monetdb.cwi.nl/SQL/Documentation/Data-Types.html, for storing string/char type date, we have following options

1.CHAR[ACTER] (L) - character string with length L

2.VARCHAR (L) | CHARACTER VARYING (L) - string with atmost length L CLOB | CHARACTER LARGE OBJECT BLOB | BINARY LARGE OBJECT DECIMAL(P,S) | NUMERIC(P,S)

My question is would CLOB would be the right choice to store variable length/ dynamic string/char data, varchar(L) is out of the picture as i wont know the length of the string.

yes, in MonetDB, clob is as expensive as char or varchar, so you can use it without any performance impact.
