The default precision for the datetime data type in MySQL is seconds. If there are errors in querying data, it may be due to a precision mismatch. There are two ways to resolve this issue.<\/p>\n

    \n
  1. Change the precision of the data type: Modify the datetime data type to timestamp data type. The timestamp data type has millisecond-level precision, which allows for more accurate storage and retrieval of time. You can use the ALTER TABLE statement to modify the field type of the data table.<\/li>\n
  2. Modify the column name to a timestamp with precision of 3 in the table.<\/li>\n
  3. Here, the (3) represents a precision of 3 milliseconds.<\/li>\n
  4. Convert data using date functions: If you are unable to change the data type, you can use date functions to convert data during the query. For example, use the DATE_FORMAT function to convert a datetime type field into a string with specified precision.<\/li>\n
  5. Retrieve the date and time in the format ‘YYYY-MM-DD HH:MM:SS.MS’ from the table.<\/li>\n
  6. The placeholder ‘%f’ here represents milliseconds and can be adjusted for precision as needed.<\/li>\n<\/ol>\n

    You can choose between the two methods depending on the specific situation. If you need more precise time accuracy, it is recommended to adjust the data type precision; if you are just temporarily querying data, you can use date functions for conversion.<\/p>\n","protected":false},"excerpt":{"rendered":"
