存储过程的numeric问题,急!!1
CREATE PROC p_ceshi
@fdnQuantity numeric(19,6),
@fdmAmount numeric(19,6)
AS
BEGIN
UPDATE tbStock SET fdnQuantity=fdnQuantity + CASE WHEN @fdnQuantity < 0 THEN '+' ELSE '-' END + Abs(@fdnQuantity),
fdmAmount=fdmAmount + CASE WHEN @fdmAmount < 0 THEN '+' ELSE '-' END + Abs(@fdmAmount)
WHERE fdlStockID=@fdlStockID
END
一直出现 将 varchar 转换为数据类型 numeric 时出现算术溢出错误。的错误,
应该是连接符号的时出的问题,可是,怎么改哟。。
------解决方案--------------------CREATE PROC p_ceshi
@fdnQuantity numeric(19,6),
@fdmAmount numeric(19,6)
AS
BEGIN
UPDATE tbStock SET fdnQuantity=fdnQuantity +
CASE WHEN @fdnQuantity < 0 THEN @fdnQuantity ELSE @fdnQuantity*-1 END ,
fdmAmount=fdmAmount + CASE WHEN @fdmAmount < 0 THEN @fdmAmount ELSE @fdmAmount*-1 END
WHERE fdlStockID=@fdlStockID
END
这个效果?
------解决方案--------------------
UPDATE tbStock
SET fdnQuantity=
CASE WHEN @fdnQuantity < 0 THEN fdnQuantity + Abs(@fdnQuantity) ELSE fdnQuantity - Abs(@fdnQuantity) END,
fdmAmount= CASE WHEN @fdmAmount < 0 THEN fdmAmount + Abs(@fdmAmount) ELSE fdmAmount - Abs(@fdmAmount) END
WHERE fdlStockID=@fdlStockID
