| Yesterday's Question of the Day |
| Yesterday's Question (by Carlo Romagnano): What are the values returned by this query? (they could be in any order) USE tempdb CREATE TABLE MyStuff(t varchar(100)) INSERT INTO MyStuff SELECT * FROM ( VALUES ('a') ,('aa') ,('aaa') ) AS V([t]) SELECT STUFF(t,2,0,CASE WHEN LEN(t) <= 2 THEN 'b' ELSE NULL END) AS Result FROM MyStuff DROP TABLE MyStuff
Answer: NULL,aba,aaa Explanation: STUFF ( character_expression , start , length , replaceWith_expression ) STUFF - click here start
If start is longer than the first character_expression, a null string is returned. replaceWith_expression
Is an expression of character data. character_expression can be a constant, variable, or column of either character or binary data. This expression will replace length characters of character_expression beginning at start.
If expression is NULL, zero length data is inserted. Row with 'a' is too short, so it returns NULL Row with 'aa' become 'aba' Row with 'aaa', because of CASE clause returns NULL as replaceWith_expression, is unchanged 'aaa' Result: NULL,aba,aaa. » Discuss this question and answer on the forums |
