将钱转换为数字数据类型的算术溢出错误 - 如何查找

Question

我在 SQL Server 的另一个表中选择和插入数据并收到以下错误：

将钱转换为数字数据类型时出现算术溢出错误。

如何确定是哪些数据导致了此问题？

CREATE TABLE foo
(
      myNum DECIMAL(10, 4)
);

INSERT INTO foo 
    SELECT 1234.567;

Answer 1

你可以使用try_convert():

select f.*
from foo f
where try_convert(decimal(10, 4), col) is null;

Answer 2

CREATE TABLE #tmp_1(col1 DECIMAL(2,0))
CREATE TABLE #tmp_2(col2 DECIMAL(12,0))
CREATE TABLE #errors (error_value VARCHAR(MAX))
INSERT INTO #tmp_2 VALUES (1222.00)
INSERT INTO #tmp_2 VALUES (122222.00)
INSERT INTO #tmp_2 VALUES (1.00)

DECLARE @rec DECIMAL(12,0)

DECLARE get_errors CURSOR FOR SELECT col2 FROM #tmp_2 
OPEN get_errors
FETCH NEXT FROM get_errors INTO @rec
WHILE @@fetch_status <> -1
BEGIN
BEGIN TRY
INSERT #tmp_1 VALUES (@rec)
END TRY
BEGIN CATCH
INSERT INTO #errors VALUES (@rec)
END CATCH
        FETCH NEXT FROM get_errors INTO @rec
END
CLOSE get_errors
DEALLOCATE get_errors

GO 
SELECT * FROM #tmp_1
SELECT * FROM #errors
DROP TABLE #tmp_1
DROP TABLE #tmp_2
DROP TABLE #errors
