Q:

The multi part identifier could not be bound is

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 MyTable.SomeRow - 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 Table1.OrderDate, 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.

Q:

Which is a reserved word in the java programming language?

A) Variable B) Identifier
C) Keyword D) Main
 
Answer & Explanation Answer: C) Keyword

Explanation:

Reserved words are words that cannot be used as object or variable names in a Java program because they're already used by the syntax of the Java programming language.

Java reserved words are keywords that are reserved by Java functions or other uses that cannot be used as identifiers (e.g., variable names, function names, class names).

If a reserved word was used as a variable you would get an error or unexpected result.

 

Examples : Int, Long, Abstract, Class, Break, Catch, Case, Public, Static, Void,...
