Correct Answer: One of the most common errors that you might face in join statements is Server: Msg 4104, Level 16, State 1, Line 1 The multi-part identifier could not be bound A multipart identifier is any description of a field or table that contains multiple parts - for instance MyTableSomeRow - if it can't be bound that means there's something wrong with it - either you've got a simple typo, or a confusion between table and column It can also be caused by using reserved words in your table or field names and not surrounding them with [] The main reason for this error is that the source table cannot be found, for example if you have statement such as Table1OrderDate, and then if you get error above, this means that Table1 cannot be found in the query Sometimes you can see that source table exists in the query, but T-SQL cannot understand it, especially when you write join statements
