Examples of Converting ‘date’ to ‘smalldatetime’ in SQL Server (T-SQL)

Posted on by Ian

This article contains examples of converting a date value to a smalldatetime value in SQL Server.

When you convert a date value to smalldatetime, extra information is added to the value. This is because the smalldatetime data type contains both date and time information. The date data type, on the other hand, only contains date information.

However, there are cases where a date to smalldatetime conversion might fail. In particular, if the date value is outside the range supported by smalldatetime then it will fail with an error.

In any case, below are examples of converting between these two data types.

Examples of Converting ‘date’ to ‘datetime2’ in SQL Server (T-SQL)

Posted on by Ian

This article contains examples of converting a date value to a datetime2 value in SQL Server.

When you convert a date value to datetime2, extra information is added to the value. This is because the datetime2 data type contains both date and time information. The date data type, on the other hand, only contains date information.

The datetime2 data type is basically an extension of the datetime data type. It has a larger date range, a larger default fractional precision, and optional user-specified precision.

In any case, the conversion process is exactly the same regardless of the data type. The only difference is the amount of information that’s available between date, datetime and datetime2.

Remember This When Formatting a TIME Data Type in SQL Server (T-SQL)

Posted on by Ian

In SQL Server, when you use the T-SQL FORMAT() function to format a time data type, you need to remember to escape any colons or periods in your format string.

This is because the FORMAT() function relies upon CLR formatting rules, which dictate that colons and periods must be escaped. Therefore, when the format string (second parameter) contains a colon or period, the colon or period must be escaped with backslash when an input value (first parameter) is of the time data type.
