In these queries, the given birth_date is not in the standard PostgreSQL date format. INSERT INTO students(first_name, last_name, birth_date)
Now let us try to insert data records in the “students” table, using the following queries. Student_id INT GENERATED BY DEFAULT AS IDENTITY,
Dev dd written update code#
We can use the following code snippet to perform the given task. In order to illustrate the uses of to_date() function, let us create a dummy “students” table. SQL query to illustrate the use of to_date() function in INSERT statements. The above mentioned query returns the input string in YYYY-MM-DD date format in the MYSQL database. So, let us try some examples which will work there as well. Since the SQL server and MYSQL do not have to_date() as a built-in function, we cannot use it there. Great, we just learned to convert character strings into date data type using to_date() function. In PostgreSQL, we can simply convert a character string written in date format to date data type without using the to_date() function in the following way. This can be solved by using the to_date function with the following set of arguments.
We can sometimes have date information mixed with a timestamp string. Suppose we have some entries which are in shorthand format like ‘070920’ and we want to convert it into YYYY-MM-DD format. We can use the following piece of code to perform the task. Next, suppose we have some date information written in text format like the one in this example.
Suppose you want to convert ‘20200526’ into YYYY-MM-DD format (stands for 4 characters of the year, followed by two characters of month and day each.) We can use the to_date() function in the following manner.
