How to insert time 2009-09-22 18:09:37.881 in mysql. Actually I can insert and retrieve the time 2009-09-22 18:09:37 in mysql but whenever I am try

Answer 1

The fractional second capability was finally added in MySQL 5.6.4. Link to documentaion: http://dev.mysql.com/doc/refman/5.6/en/fractional-seconds.html

Answer 2

All time types in MySQL have only a precision of seconds

[...] microseconds cannot be stored into a column of any temporal data type. Any microseconds part is discarded.

You'll need some workaround.

Answer 3

I got the issue resolved. The database was not allowing the insertion of time in millisecond. Please have a look at the lines, below:

CREATE TABLE MyTimeStamp(TimeData decimal(17,3));

INSERT INTO  MyTimeStamp(TimeData) values (20090922201843.426);

SELECT timestamp(TimeData) FROM MyTimeStamp;

OutPut:

2009-09-22 20:018:43.426000

Answer 4

Having had a quick scan on the MySQL reference pages here, they seem to suggest that you cannot add milliseconds to a column of type datetime. The direct quote is

"However, microseconds cannot be stored into a column of any temporal data type. Any microseconds part is discarded."

This implies that you cannot use Timestamp either.

Are the miliseconds necessary? Could they be stored in a secondary column and then recombined with the basic datetime upon retrieval?

Answer 5

<?
# PHP
$microtime = microtime(true);
$datetime = date("Y-m-d H:i:s");
?>

MYSQL

• CREATE field col_datetime - DATETIME)
• CREATE field col_microtime - DECIMAL(15,4)

ADD: INSERT INTO your_table (col_datetime,col_microtime) values ('$datetime','$microtime')

List new->old: SELECT * FROM yout_table ORDER BY col_microtime DESC

List old->new: SELECT * FROM yout_table ORDER BY col_microtime
