Question

我的表格中包含VARCHAR列，其中包含时间。价值如下所示：

TXN_TIME
--------
053124
173932
011815
120349
134207

我需要转换它

TXN_TIME
--------
05:31:24:000000
17:39:32:000000
01:18:15:000000
12:03:49:000000
13:42:07:000000

请举一些例子..

Answer 1

不清楚您的结果是VARCHAR还是实际的TIME类型，所以这两者都是：

DECLARE @Table TABLE (
    TXN_TIME VARCHAR(6)
)

INSERT INTO @Table
SELECT '053124'
UNION
SELECT '173932'
UNION
SELECT '011815'
UNION
SELECT '120349'
UNION
SELECT '134207'

SELECT  TXN_TIME,
        LEFT(TXN_TIME,2) + ':' + SUBSTRING(TXN_TIME,3,2) + ':' + SUBSTRING(TXN_TIME,5,2) + ':000000' AS Converted,
        CONVERT(TIME(6),LEFT(TXN_TIME,2) + ':' + SUBSTRING(TXN_TIME,3,2) + ':' + SUBSTRING(TXN_TIME,5,2)) AS ConvertedTime
FROM @Table

结果：

/----------------------------------------------\
| TXN_TIME |    Converted    |  ConvertedTime  |
|----------+-----------------+-----------------|
|  011815  | 01:18:15:000000 | 01:18:15.000000 |
|  053124  | 05:31:24:000000 | 05:31:24.000000 |
|  120349  | 12:03:49:000000 | 12:03:49.000000 |
|  134207  | 13:42:07:000000 | 13:42:07.000000 |
|  173932  | 17:39:32:000000 | 17:39:32.000000 |
\----------------------------------------------/
