Choosing a column for primary key

2003-03-27 Thread Aaron Williams
I'd like to know about any potential issues of choosing a char(32) as the column type of a primary key instead of BIGINT or some other numeric type. A little background. I would like to generate a unique identifier to use as a primary key for our application instead of using an AUTOINCREMENT
