RIGHT (SSIS Expression)

 

Applies To: SQL Server 2016

Returns the specified number of characters from the rightmost portion of the given character expression.

  
RIGHT(character_expression,integer_expression)  

character_expression
Is a character expression from which to extract characters.

integer_expression
Is an integer expression that indicates the number of characters to be returned.

DT_WSTR

If integer_expression is greater than the length of character_expression, the function returns character_expression.

If integer_expression is zero, the function returns a zero-length string.

If integer_expression is a negative number, the function returns an error.

The integer_expression argument can take variables and columns.

RIGHT works only with the DT_WSTR data type. A character_expression argument that is a string literal or a data column with the DT_STR data type is implicitly cast to the DT_WSTR data type before RIGHT performs its operation. Other data types must be explicitly cast to the DT_WSTR data type. For more information, see Integration Services Data Types and Cast (SSIS Expression).

RIGHT returns a null result if either argument is null.

The following example uses a string literal. The return result is "Bike".

RIGHT("Mountain Bike", 4)  

The following example returns the number of rightmost characters that is specified in the Times variable, from the Name column. If Name is Touring Front Wheel and Times is 5, the return result is "Wheel".

RIGHT(Name, @Times)  

The following example also returns the number of rightmost characters that is specified in the Times variable, from the Name column. Times has a noninteger data type and the expression includes an explicit cast to the DT_I2 data type. If Name is Touring Front Wheel and Times is 4.32, the return result is "heel" because the RIGHT function converts the value of 4.32 to 4, and then returns the rightmost four characters.

RIGHT(Name, (DT_I2)@Times))
