然后,我们使用GETDATE()函数获取当前日期和时间,并将其转换为字符串格式。接下来,我们构建了一个动态 SQL 语句,该语句将日期插入到myTable表的dateColumn列中。最后,我们使用sp_executesql存储过程执行动态 SQL 语句。 总之,在 TSQL 中,我们可以使用GETDATE()或CURRENT_TIMESTAMP函数将日期插入到动态 SQL 语句中。

CURRENT_TIMESTAMP 會從執行 SQL Server 執行個體之電腦的作業系統衍生此值。注意 SYSDATETIME 和SYSUTCDATE 比GETDATE 和GETUTCDATE 具有更高的精確度,以小數秒數有效位數來度量。 SYSDATETIMEOFFSET 函式包含系統時區位移。 您可以將 SYSDATETIME、SYSUTCDATETIME 和SYSDATETIMEOFFSET 指派給任何日期和時間類型的變數。
