SQL：如何将值转换为小写并附加s？

Question

我想这样做，但我知道这不是正确的语法：

INSERT INTO
               TBL1 SELECT 
               Col1.ToLower + 's'
FROM
               TBL2

Answer 1

INSERT INTO TBL1 SELECT LOWER(Col1) + 's'
FROM TBL2

Answer 2

像这样：

INSERT INTO TBL1 SELECT LOWER(Col1) + 's'
FROM TBL2 

Answer 3

INSERT INTO TBL1 
SELECT Lower(Col1) + 's'
FROM TBL2
