ToInt64(DateTime) 呼叫這個方法一律會擲回 InvalidCastException。 ToInt64(Boolean) 將指定的布林值轉換為相等的 64 位元帶正負號的整數。 ToInt64(Double) 將指定之雙精確度浮點數的值,轉換為相等的 64 位元帶正負號的整數。 ToInt64(Int16) 將指定的 16 位元帶正負號的整數值轉換為相等的 64 位元帶正...
CONVERT(event_date_string, DATETIME):将event_date_string转换为DATETIME类型。 3. 使用STR_TO_DATE函数 如果数据的格式不标准,或者不易直接使用CONVERT函数,例如日期是用不同的分隔符或者格式不一致时,我们可以使用STR_TO_DATE函数: SELECTevent_date_string,STR_TO_DATE(event_date_string,'%Y-%m-%d %H:%i:...
Example 1: Convert Single Column to DateTime Object The below code converts the single column to a DateTime object: import pandas df= pandas.DataFrame({'Courses':['Python','Java','C++'],'Starting Date':['5/21/2023','3/24/2028','5/20/2023']}) ...
