问题描述
SET @newNum = IF(

REPLACE("-600.00",",",""),
-1*REPLACE(REPLACE("-600.00",",",""),"-","")
);
我不断收到一个被截断的不正确的 DOUBLE 值:'-' 执行此行时,有人知道是什么原因造成的吗?
I keep getting a truncated incorrect DOUBLE value: '-' when executing this line, anyone know what is causing this ?
推荐答案
REGEXP
返回 1 或 0,具体取决于是否匹配.将结果与 -
进行比较是不正确的,您可以这样做:
REGEXP
returns 1 or 0 depending on whether there is a match or not. Comparing the result with -
is incorrect, you can do this instead:
DECLARE @oldNum VARCHAR(10);
DECLARE @newNum VARCHAR(10);
SET @oldNum = '600.00-';
SET @newNum = IF(
RIGHT(@oldNum, 1) = '-',
CONCAT('-', REPLACE(REPLACE(@oldNum, ',', ''), '-', '')),
REPLACE(@oldNum, ',', '')
);
SELECT @oldNum, @newNum
