How Can I Convert a String to DateTime in SQL Server and Update a Database Field?

Converting Strings to Datetime in SQL Server

While there are multiple ways to convert an arbitrary string to datetime in MSSQL, a specific concern arises when you want to control the string format and update a datetime field with a date string. The appropriate syntax for this operation is leveraging the CONVERT function.

To update a datetime field called MyDate with a date string in the format 'YYYY/MM/DD HH:MM:SS', the following syntax can be employed:

UPDATE MyTable SET MyDate = CONVERT(datetime, '2009/07/16 08:28:01', 120)

The CONVERT function takes three parameters:

1. The data type to which the string should be converted (in this case, datetime)
2. The string to be converted
3. A style parameter that specifies the format of the string (for date/time conversions, style 120 is used)

For a comprehensive guide on the CAST and CONVERT functions, including various date formatting options, refer to the following Microsoft documentation:
