STUFF ( character_expression , start , length ,character_expression )
character_expression

Is an expression of character data. character_expression can be a constant, variable, or column of either character or binary data.

start

Is an integer value that specifies the location to start deletion and insertion. If start or length is negative, a null string is returned. If start is longer than the first character_expression, a null string is returned. start can be of type bigint.

length

Is an integer that specifies the number of characters to delete. If length is longer than the first character_expression, deletion occurs up to the last character in the last character_expression. length can be of type bigint.

Returns character data if character_expression is one of the supported character data types. Returns binary data if character_expression is one of the supported binary data types.

An error is raised if the resulting value is larger than the maximum supported by the return type.

The following example returns a character string created by deleting three characters from the first string, abcdef, starting at position 2, at b, and inserting the second string at the deletion point.

SELECT STUFF('abcdef', 2, 3, 'ijklmn')
GO

Here is the result set.

--------- 
aijklmnef
