STUFF (SQL Server Compact)

Deletes a specified length of characters and inserts another set of characters at a specified starting point.


STUFF (character_expression, start, length, character_expression )

character_expression: An expression that can be implicitly converted to nvarcharor ntext.
start: An integer value or an expression that can be implicitly converted to int, which specifies the location to begin deletion and insertion. If start is negative, a null string is returned. If start is longer than the first character_expression, a null string is returned.
length: An integer or an expression that can be implicitly converted to int, which 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. If length is negative, a null string is returned.

nvarchar or ntext

The following example deletes the second digit of the product ID in the Productstable and replaces it with the characters '000'.

SELECT STUFF([Product ID], 2,1, '000')
FROM Products
