Conversion Failed When Converting Date And/Or Time from Character String While Inserting Datetime

Conversion failed when converting date and/or time from character string while inserting datetime

There are many formats supported by SQL Server - see the MSDN Books Online on CAST and CONVERT. Most of those formats are dependent on what settings you have - therefore, these settings might work some times - and sometimes not.

The way to solve this is to use the (slightly adapted) ISO-8601 date format that is supported by SQL Server - this format works always - regardless of your SQL Server language and dateformat settings.

The ISO-8601 format is supported by SQL Server comes in two flavors:

• YYYYMMDD for just dates (no time portion); note here: no dashes!, that's very important! YYYY-MM-DD is NOT independent of the dateformat settings in your SQL Server and will NOT work in all situations!

or:

• YYYY-MM-DDTHH:MM:SS for dates and times - note here: this format has dashes (but they can be omitted), and a fixed T as delimiter between the date and time portion of your DATETIME.

This is valid for SQL Server 2000 and newer.

So in your specific case - use these strings:

insert into table1 values('2012-02-21T18:10:00', '2012-01-01T00:00:00');

and you should be fine (note: you need to use the international 24-hour format rather than 12-hour AM/PM format for this).

Alternatively: if you're on SQL Server 2008 or newer, you could also use the DATETIME2 datatype (instead of plain DATETIME) and your current INSERT would just work without any problems! :-) DATETIME2 is a lot better and a lot less picky on conversions - and it's the recommend date/time data types for SQL Server 2008 or newer anyway.

SELECT
   CAST('02-21-2012 6:10:00 PM' AS DATETIME2),     -- works just fine
   CAST('01-01-2012 12:00:00 AM' AS DATETIME2)   -- works just fine  

Don't ask me why this whole topic is so tricky and somewhat confusing - that's just the way it is. But with the YYYYMMDD format, you should be fine for any version of SQL Server and for any language and dateformat setting in your SQL Server.

SQL Error : Conversion failed when converting date and/or time from character string

I found the issue, it's a very very stupid mistake, there was one column with a text format I couldn't see it because I checked with length, but the SQL gives max length so I used group by and manually check dates until I found one column that's not correct in 1 m account records

SQL - Conversion failed when converting date and/or time from character string

What you can do is update the value using try_convert() first and then alter the column name. Note: This will set any invalid values to NULL.

update customer
    set dob = try_convert(date, dob);

alter table customer alter column dbo date;

If you want to see the bad values, then before you change the table, run:

select c.*
from customer c
where try_convert(date, dob) is null and dob is not null;

You may have other ideas on how to fix the values.

T SQL Conversion failed when converting date and/or time from character string from VARCHAR(MAX)

I have a date stored as varchar(MAX)

There's your problem right there.

Not only you are using the wrong data type to store dates, you are also using max which is a known performance killer.

The solution to the problem is to alter the table and store dates in a Date data type - but first, you must look up all the objects that depends on that column and make sure they will not break or change them as well.

Assuming this can't be done, or as a temporary workaround, you must first convert the data you have to Date, and then convert it back to a string representation of that date using the 103 style to get dd/mm/yyyy.

Since yyyy-mm-dd string format is not culture dependent with the date data type, you can simply do this:

SELECT CONVERT(char(10), TRY_CAST(DateField As Date), 103) As [JobStartDate]
FROM tblTest

Note I've used try_cast and not cast since the database can't stop you from storing values that can't be converted to dates in that column.

Datetime! Conversion failed when converting date and/or time from character string

You can try this:

select 
    try_convert(datetime2(7), 
                 STUFF(STUFF(REPLACE('2019-02-18-13.10.46.485000015','.',':'), 11, 1, ' '),20,1,'.')
               ,121)

Conversion failed when converting date and/or time from character string when selecting in CTE

You can try using some default date value instead of '0'

CASE WHEN j.PHPPDT = '00010101' THEN '12/31/2099' ELSE j.PHPPDT END AS NEWPPDT,
CASE WHEN j.PHPDTE = '00010101' THEN '12/31/2099' ELSE j.PHPDTE END AS NEWPROMDT

Getting Conversion failed error when converting date and/or time from character string

Storing datetime in varchar column is bad idea.Use appropriate column type when storing data.

Considering your question i assume there is invalid characters included in data like CR, LF or CR+LF.

try to replace them by

SELECT REPLACE(REPLACE(@str, CHAR(13), ''), CHAR(10), '')
