c# - Convert datetime to smalldatetime in sql insert query

Question

I have an INSERT query like this

INSERT INTO tna_temp_attendance VALUES('" + strEmpCode + "', CONVERT(SMALLDATETIME, '" + dtDateTime.ToString() + "'), 0, " + _inOutMode.ToString() + ", null, 0, 'CHO-', '" + strMachine + "')

When I execute this query there is this error occurred "the conversion of a varchar data type to a datetime data type resulted in an out-of-range value"

Help Plz

My database has this table "tna_temp_attendance" and its columns are

• Emp_id char(6)
• Wdate smalldatetime
• Is_read bit
• Machine_Status bit
• Process_Status bit
• Is_Error bit
• Loc_no char(4)
• Ip varchar(16)

Edit

I passed the date like this also

CONVERT(SMALLDATETIME, '" + Convert.ToDateTime(dtDateTime.ToString("yyyy-MM-dd hh:mm:ss")) + "')

But it also not working

Answer 1

我终于做到了。我声明了一个字符串。

• 字符串 dt = DateTime.Now.ToString();

然后将其转换为 DateTime

DateTime ndt = Convert.ToDateTime(dt);

然后我用

CONVERT(SMALLDATETIME, CONVERT(DATETIME, '" + ndt + "'))

它奏效了。多谢你们

尝试使用 ISO 格式将日期插入 SQL 服务器，如下所示：

dtDateTime.ToString("yyyyMMdd")
