If the varchar2 column is less than 2 chars then it will be padded with blanks and THEN compared with CHAR column. That's all.

QOTD: Any clod can have facts, but having an opinion is an art! -----Original Message----- Sent: Monday, April 22, 2002 6:13 PM To: Multiple recipients of list ORACLE-L Is there any overhead (ie. internal conversion) in comparing a char to a varchar2? We found an instance where a primary key in one table is defined as char(2) and the foreign key referencing it from another table is varchar2(2). We are going to change it, but I'm curious what, if anything, happens when resolving the integrity?
