If you mean you want to sort by date first then by names SELECT id, name, form_id, DATE (updated_at) as date FROM wp_frm_items WHERE user_id = 11 && form_id=9 ORDER BY updated_at DESC,name ASC This will sort the records by date first, then by name It depends on how you stored date in your date field. In my case, it is separated by / so I used -... ORDER BY STR_TO_DATE(report_date, '%m/%d/%Y') DESC; In case, if you're using - to separate date, month and year, then you can use -... ORDER BY STR_TO_DATE(report_date, '%m-%d-%Y') DESC SELECT * FROM `kunden` ORDER BY name ASC Das ASC am Ende bedeutet Ascending und heißt aufsteigend. Das Ergebnis soll also abhängig von der Spalte name aufsteigend (ASC) sortiert werden. Möchte man es absteigend sortieren, nutzt man DESC (descending) In this case, the ORDER BY clause: First, sort the result set by the values in the column1 in ascending order. Then, sort the sorted result set by the values in the column2 in descending order. Note that the order of values in the column1 will not change in this step, only the order of values in the column2 changes

Similarly to SQLite, MySQL treats NULL values as lower than any non-NULL value; thus, by default, it puts these values first when sorting in ascending order and last when sorting in descending order. However, MySQL does not support the NULLS FIRST / NULLS LAST options, which makes it more. SQL order by case can be used when we have to order the data on a conditional basis and define the criteria on which the ordering will be done based on a certain condition. The order by clause can be helpful for sorting data in ascending or descending manner by simply specifying the column on which the sorting is to be done or multiple columns if sorting is to be done considering all of them.

PHP MySQL - SELECT, ORDER BY. When the database has some records in it, you can retrieve the stored information with the SELECT statement. A SELECT query returns rows selected from one or more tables. - Syntax : SELECT column_name (s) FROM table_name. - column_name (s) - is the name of the column (or columns) you want to select The ORDER BY clause is used in SQL queries to sort the data returned by a query in ascending or descending order. If we omit the sorting order, it sorts the summarized result in the ascending order by default. The ORDER BY clause, like the GROUP BY clause, could be used in conjunction with the SELECT statement In MySQL NULL values are considered lower than any non-NULL value, therefore, NULL values appear first when the order is ASC (ascending), and ordered last when the order is DESC (descending). We'll be discussing the following two cases as sorting NULL values in either of the cases might not be straightforward: . Ordering NULL values last whilst sorting all non-NULL values first in an ascending.

By default, Node.js MySQL ORDER BY results in an ascending order of elements, or you may also use ASC keyword. For descending order of records, DESC keyword should be used.

When you query a MySQL database, you can sort the results by any field in an ascending or descending order just by adding ORDER BY at the end of your query.You use ORDER BY field_name ASC for an ascending sort (which is the default) or ORDER BY field_name DESC for a descending sort. You can use an ORDER BY clause in a SELECT statement, SELECT LIMIT or DELETE LIMIT statement Data is ordered depending on the data type. Text is ordered according to collating sequence, numbers from low to high (e.g. -100 is before 5), and dates are ordered from earliest to latest. So 'Three' is greater than 'Four' because T is after F in the collating sequence. But 3 is less than 4 whether stored as numbers or text. I hope that helps You can sort on multiple columns, and you can sort different columns in different directions. For example, to sort by type of animal in ascending order, then by birth date within animal type in descending order (youngest animals first), use the following query

TO_DATE() function in most SQL database management servers such as PostgreSQL and ORACLE is used to convert data values of character data types such as VARCHAR, NVARCHAR, CHAR etc. to standard DATE data type.

MySQL-Anweisung: Auswahl aller Spalten For the query with no order preference, SQL Server can stream grouped rows using a Hash Match Flow Distinct. If it encounters the required number of distinct entries quickly, the execution time is short. When a specific order is required, SQL Server must test every row. For example, to place rows in name order, it must sort all rows by name In SQL, how do distinct and order by work together? The best way to illustrate this is through an example. Let's say that we have a table called Orders like the one below - where each row represents a separate order.
