How to Add Multiple Camera Feeds with a SwitcherĪ video switcher (or video mixer) is a device or software program that selects between multiple incoming video signals from various sources (camera, PowerPoint feed, etc.) and directs one of those signals to a single output, including a streaming device, video recorder, or a display device (i.e. If you're looking to enhance the value of your live stream, integrating multiple camera angles is a great way to get started.

It's part of our series on live streaming equipment. It gives an introduction to this piece of equipment.

FebruThis post covers how to add multiple camera angles using a video switcher (mixer).

I’ve also written a post that shows how to convert between date formats using the CONVERT() function using the same examples as above. Here’s an example of converting the date that’s retrieved from a column in the WideWorldImporters sample database: USE WideWorldImporters ĬAST(LastEditedWhen AS date) AS 'Converted' Here’s an example using a different function to generate the original date/time value: SELECTĬAST(SYSDATETIMEOFFSET() AS date) AS Converted Įxample 6 – Converting from a Database Query Like this: SELECTĬAST(SYSDATETIME() AS time) AS Converted Įxample 5 – Cast SYSDATETIMEOFFSET() as date You can also cast it as a time data type, so that only the time component is returned. You aren’t limited to displaying the date component of the value. SELECTĬAST(SYSDATETIME() AS datetimeoffset) AS Converted In this example, we cast the date as a datetimeoffset data type. SELECTĬAST(SYSDATETIME() AS smalldatetime) AS Converted Įxample 3 – Cast SYSDATETIME() as datetimeoffset In this example, we cast the date as a smalldatetime data type. +-+-+Įxample 2 – Cast SYSDATETIME() as smalldatetime SELECTĬAST(SYSDATETIME() AS date) AS Converted Note that the SYSDATETIME() generates its value as a datetime2(7) data type, so we are converting it from that data type to another data type. In this example, we generate the current date/time with the SYSDATETIME() function and cast the return value as a date data type. length An optional integer that specifies the length of the target data type. This includes xml, bigint, and sql_variant. These arguments are defined as follows: expression Any valid expression. The syntax goes like this: CAST ( expression AS data_type )

In any case, this article provides examples of converting between different date formats using CAST(). Many database professionals prefer CAST() due to the fact that it’s part of the ANSI SQL standard, however, others prefer CONVERT() due to the extra functionality that T-SQL’s implementation offers (such as being able to provide a date style). So in many cases, you have the option of which of these functions you prefer to use. The CAST() function is part of the ANSI SQL standard, and it does most of the things CONVERT() does. However, that’s not the only function in the T-SQL toolbox for converting between data types. In SQL Server, you can use use the CONVERT() function to convert a date value from one date data type to another (or between any other data type for that matter).
