[Monetdb-developers] select data type to store variable length string
Hello,
Thank you everyone for being supportive!
I have a brief query about the data types, according to the documentation 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.
Thank you for your time and help!

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