I have data in one of my tables as "Sun Dec 14 22:49:13 2014 -0800" and need to load it into another table but skipping the time filed i.e. HH:MM:SS.

I used:

insert into final_data
select Book_Name, Author_Name, Author_email,
str_to_date(substring_index(date_string,' ',4),'%a %b %d %Y'),
from data;

ERROR 1292 (22007): Truncated incorrect date value: 'Sun Dec 14 22:49:13'

I can use str_to_date(substring_index(date_string,' ',5),'%a %b %d %T %Y') but that will add HH:MM:SS in the column as well. Is there a way to load the data skipping HH:MM:SS ? i.e instead of 2014-12-14 22:49:13 it diplays 2014-12-14

  • What is the type of the column in the old and the new table? – ypercubeᵀᴹ Aug 14 '19 at 17:18
  • Both of them are varchar – Oracle75 Aug 14 '19 at 17:27
  • Then why are you converting your output to date? – mustaccio Aug 14 '19 at 17:32
  • Please share table create statement and perhaps using the date format function during the select statement would work – Nawaz Sohail Aug 14 '19 at 17:40
  • create table final_data (Commit varchar(100), Author_Name varchar(100), Author_email varchar(100), Date_String varchar(50), Total_Sold int(4)); – Oracle75 Aug 14 '19 at 17:52

you have to pass your datetime column into date() function like this :

create table test (
  datetime_string datetime,
  date_date date,

insert into test(datetime_string) values('2014-12-14 22:49:13');
update test set date_date = date(datetime_string);


  • it's more straightforward than your risky manipulation – eytienne Aug 14 '19 at 18:31
  • It worked - thank you @eytienne and thanks a lot everyone for your help. – Oracle75 Aug 14 '19 at 19:28
  • How is that even relevant?? The incoming data is not formatted correctly: "Sun Dec 14 22:49:13 2014 -0800" – Rick James Aug 14 '19 at 22:25
  • could you up vote ? (because the formatting seems good in the error message so it worked) – eytienne Aug 17 '19 at 20:45
