Question
Write a query to display the coursename of the courses whose month of batch start date is between 'February' and 'July'. Display the records sorted in ascending order based on coursename.
Solution
Assuming you are using SQL, here is a step-by-step guide on how to write the query:
-
Identify the table: The first step in writing a SQL query is to identify the table from which you want to retrieve the data. In this case, the table would be the one that contains course information including the course name and batch start date.
-
Write the SELECT statement: The SELECT statement is used to select data from a database. The data returned is stored in a result table, called the result-set. In this case, you want to display the coursename, so your SELECT statement would start like this:
SELECT coursename. -
Write the FROM statement: The FROM statement is used to specify the table from which to retrieve the data. If your table is named "courses", your query would now look like this:
SELECT coursename FROM courses. -
Write the WHERE statement: The WHERE clause is used to filter records. In this case, you want to filter the records where the month of the batch start date is between February and July. Assuming your date column is named "startdate", your query would now look like this:
SELECT coursename FROM courses WHERE MONTH(startdate) BETWEEN 2 AND 7. -
Write the ORDER BY statement: The ORDER BY keyword is used to sort the result-set in ascending or descending order. In this case, you want to sort the records in ascending order based on coursename. Your final query would look like this:
SELECT coursename FROM courses WHERE MONTH(startdate) BETWEEN 2 AND 7 ORDER BY coursename ASC.
Please note that the MONTH() function extracts the month from the date and it's used in the format MONTH(date). The months are represented as numbers in SQL, where 1 is January and 12 is December. Therefore, February is represented as 2 and July as 7.
