The CAST function is often used to preserve decimal values and places while converting them into integers. The function can also truncate the decimal value if needed. Cite APA 7 Franscisco,.

Thought their syntax is different, both functions are able to convert values from one formation to another. The numbers shown in red are the style formatter. There are many style formats you can use. The complete list is here. There are several reasons I can think of:.

What do you think? One important issue with CAST is when converting any value to a binary data type of a different length than the original, the SQL Server pads or truncates the data on the right side of the value, whereas for any other data types it pads or truncates the data to the left side. The user must state the data type, the length of the data type and the expression that needs to be converted. The style is specific to the data type that is being converted. While both the functions perform the same objective, conversion of data, there are a few differences between the two.

In some conversions the CAST function offers faster and easier performance or vice-versa. CAST is also handier when it comes to converting decimals and numeric values, as the function can keep the decimals from the original expressions. I felt really bad, as she was under pressure to get some summary information to her boss, the built-in reports were falling short, and to make them better would require her to know SQL.

At that time that seemed impossible! Then I discovered a way for anyone with the desire to easily learn SQL. Sometimes the information seems abstract or too conceptual. I really like to use diagrams or videos to explain hard-to-grasp ideas. Having video, pictures, and text really help to reinforce the point and enable learning. And now I want to help you get the same results.
