Runtime Error

What This Error Means

This error occurs when SQL Server encounters a datetime value that cannot be converted from a string to a datetime format. This is often caused by invalid or incorrect date formats in the data.

Why It Happens

This error typically happens when trying to insert or update datetime values in a SQL Server database. It can be caused by a mismatch between the expected date format and the actual format in the data. For example, if the column expects a date in the format 'YYYY-MM-DD', but the data is in the format 'MM-DD-YYYY'.

How to Fix It

1. 1To fix this error, ensure that the date format in the data matches the expected format in the SQL Server column. You can use the CONVERT function to explicitly convert the date string to the correct format. For example:
2. 2// Before (broken code)
3. 3INSERT INTO dates (date_column) VALUES ('02-28-2024');
4. 4// After (fixed code)
5. 5INSERT INTO dates (date_column) VALUES (CONVERT(datetime, '02-28-2024', 110));

Example Code Solution

INSERT INTO dates (date_column) VALUES ('02-28-2024');

INSERT INTO dates (date_column) VALUES (CONVERT(datetime, '02-28-2024', 110));
