How to Convert Strings to DateTime Objects in SQL Server?

Converting Strings to Datetime in SQL Server

When working with datetime fields in Microsoft SQL Server, it is often necessary to convert strings representing dates into datetime objects for database operations. This article provides the specific syntax for performing such conversions, addressing a more specific use case where you can control the string format.

To update a datetime field using a controlled date string, use the following syntax:

UPDATE MyTable SET MyDate = CONVERT(datetime, 'YourDateString', 120)

In this example:

• MyTable is the table containing the datetime field you want to update.
• MyDate is the name of the datetime field.
• 'YourDateString' is the string representing the date you want to convert.
• 120 is the style number that specifies the date format of the string. For a list of style numbers and their corresponding formats, refer to the MSDN documentation at https://learn.microsoft.com/en-us/sql/t-sql/functions/cast-and-convert-transact-sql.

To delve further into casting and converting datetime values in SQL Server, including discussions on the different date formatting options, consult the comprehensive MSDN Library resource at https://learn.microsoft.com/en-us/sql/t-sql/functions/cast-and-convert-transact-sql.
