Final answer:
To get the date from datetime in SQL, you can use the DATE() function in MySQL or the CONVERT() function in SQL Server to extract just the date component from a datetime value.
Step-by-step explanation:
To extract the date from a datetime in SQL, different functions can be used depending on the SQL dialect in use. For example, in MySQL, you would use the DATE() function, whereas in SQL Server, you have the CONVERT() function alongside a style parameter. Below are examples for both databases:
- MySQL: SELECT DATE(datetime_column) FROM table_name;
- SQL Server: SELECT CONVERT(date, datetime_column) FROM table_name;
These statements will return only the date portion from a datetime value. It is important to replace datetime_column with the actual column name containing datetime data and table_name with the name of the table where the column is located.
Suppose you have a table called Orders with a column called OrderDate which is of type datetime. You can retrieve only the date portion from this column using the following SQL query:
SELECT DATE(OrderDate) AS OrderDate FROM Orders;
In this example, the DATE function is used to extract the date from the OrderDate column and the result is aliased as OrderDate in the result set. The query will return a result set with only the date portion of the datetime values.
