How can I solve the issue of conversion failure when converting date time from a character string?

In the context of DevOps, if you get the error message “ conversion failed when converting datetime from character string” then it refers to there being a mismatch between the format of date and submitted format in your particular database. To resolve this particular issue, you can follow the following steps:-

Checking the format of the date

Ensure that you have entered a correct and appropriate format of date for the database field.

Use Proper datetime format

If your date format is different then try to convert the user-submitted date format to ensure the proper format of datetime before inserting it into the database.

For example, the right format of datetime in the SQL server is 

  YYYY-MM-DD HH:MM:SS (e.g., 2023-01-05 08:30:00’).

Here is the example given of how you can convert the user-submitted date to the above date format before the process of inserting:-

Assuming @userDate is the user-submitted date in a different format

  DECLARE @userDate VARCHAR(50) = ‘01/05/2023 08:30 AM’;

Convert the user-submitted date to the proper format

DECLARE @formattedDate DATETIME = CONVERT(DATETIME, @userDate, 101); -- 101 is the code for MM/DD/YYYY format
Insert @formattedDate into the database
INSERT INTO YourTable (DateTimeColumn) VALUES (@formattedDate);
