Mysql like order by1/22/2024 The following SQL query will sort MySQL results order by best match in the LIKE search. Here we will show you how to sort results by best match using LIKE in MySQL. In LIKE search, the results must be sorted based on the word matches to make the result-set more relevance. Because the result-set will not be relevance with ORDER BY in MySQL. But the ascending or descending order is not useful on a search result with the LIKE operator. On another hand, the ORDER BY keyword allows you to sort the result-set in ascending or descending order based on a specific column. For queries like SELECT WHERE conditions ORDER BY sort LIMIT N, the optimizer may choose the index to resolve ORDER BY instead of using an index on the. Use it with an ORDER BY clause to sort the rows in ascending order by date.When you use LIKE operator to search and fetch the matched results from the database, the records are selected based on their entry. STR_TO_DATE(CONCAT(exam_year, ' ', exam_month, ' ', exam_day), '%Y %M %d') %Y stands for year, %M stands for month (its full name, not a number), and %d stands for day. ![]() The second argument of this function is the date format. Then, you need to convert this string to a date using the STR_TO_DATE(date_string, '%Y %M %d') function. Since you'd like to get a string in the 'Year Month Day' format, the arguments are exam_year, exam_month, exam_day, and the spaces between them. You don't need to cast numbers to strings. The CONCAT() function combines all the arguments into one string. But first, you need to create a string using the CONCAT() function:ĬONCAT(exam_year, ' ', exam_month, ' ', exam_day) If you have a date stored as a string in the 'Year Month Day' format, you can cast it to a date using STR_TO_DATE(date_string, '%Y %M %d'). To do this, use the STR_TO_DATE() function. Add a separate table, something like this: CREATE TABLE neworder ( myorder BIGINT (20) UNSIGNED NOT NULL, mynumber BIGINT (20) NOT NULL, PRIMARY KEY (myorder), UNIQUE KEY mynumber (mynumber) ) ENGINEINNODB This table will now be used to define your own order mechanism. To sort by date, create date values from the year, the month, and the day values. The result looks like this (the rows are sorted in ascending order by exam_year, exam_month, and exam_date): subject ORDER BY STR_TO_DATE(CONCAT(exam_year, ' ', exam_month, ' ', exam_day), '%Y %M %d') The months are given in names, not in numbers. The default sort order is ascending, with smallest values first. ![]() The exam table has the following columns: subject, exam_year, exam_month, and exam_day. You can force a case-sensitive sort for a column by using BINARY like so: ORDER BY BINARY colname. Also, the rows with the same exam_date are displayed in random order (you may see Science third and Health fourth, or Health third and Science fourth). Note that in MySQL, NULLs are displayed first when sorting in ascending order and last when sorting in descending order. If you'd like to see the latest date first and the earliest date last, you need to sort in descending order. The LIKE operator is used in a WHERE clause to search for a specified pattern in a column. Hence, if you would like your results plotted in reverse order, DESC is the keyword to. You could also use the ASC keyword to make it clear that the order is ascending (the earliest date is shown first, the latest date is shown last, etc.). The alternative is to use DESC, which is abbreviated from descending. This way, you'll sort the data in ascending order by this column. Use the ORDER BY keyword and the name of the column by which you want to sort. The result looks like this (the rows are sorted in ascending order by exam_date): subject ![]() The exam table has two columns, subject and exam_date. You want to sort the rows by date in MySQL.
