This is a guest post from Phil Factor. Phil Factor real name withheld to protect the guilty , aka Database Mole, has 30 years of experience with database-intensive applications. Despite having once been shouted at by a furious Bill Gates at an exhibition in the early s, he has remained resolutely anonymous throughout his career. Some developers resort to using the MAX specification, which is a mistake too. Phil Factor explains the dangers and then offers a workaround for the problem, when you're importing text and simply don't know the correct length of each string. Why one and thirty? Some developers assume that, if they leave the length out, SQL Server will work out what they need. Alternatively, you might end up using MAX as the length, which brings troubles of its own. This can get more unpleasant if you do the same with a variable, because the string gets truncated to a single character, but there is no error.
