The ORDER BY command is used to sort the result set in ascending or descending order. The ORDER BY command sorts the result set in ascending order by default. To sort the records in descending order, use the DESC keyword.Since a lot of people think SQL processes queries from top to bottom as they have written. But SQL processes queries in the order: FROM, JOIN, WHERE, GROUP BY, HAVING, SELECT, DISTINCT, ORDER BY, and finally, LIMIT/OFFSET.ORDER BY is used with the SQL SELECT statement and is usually specified after the WHERE, HAVING, and GROUP BY clauses. Some databases sort the query results in an ascending order by default. To sort the data in ascending order, we use the keyword ASC. To sort the data in descending order, we use the keyword DESC.
How do you use ORDER BY clause : SQL ORDER BY clause is used after the WHERE clause (i.e. after filtering the data) to sort the result in either Ascending or Descending order. DESC: Keyword is used to arrange the result in Descending Order. Note: Ascending is a default sort order.
How to use ORDER BY in MySQL
ORDER BY syntax in MySQL
columnN FROM table_name ORDER BY expression [ASC|DESC]; In the ORDER BY syntax, MySQL uses the following parameters: column1, column2… – the names of the columns to retrieve the data from (it can be one or multiple columns). table_name – the name of the table containing the data we need.
What is ORDER BY clause in SQL with example : The ORDER BY clause specifies the particular order in which you want selected rows returned. The order is sorted by ascending or descending collating sequence of a column's or an expression's value. The result follows. Note: Null values are ordered as the highest value.
If there are multiple queries in a batch then these queries will be executed in the order they appear in the batch. After the execution of Query 1 is finished then the update query will be executed. You can run debugger to see the sequential execution.
What Is SQL's Order of Execution
- FROM/JOIN. The FROM and/or JOIN clauses are executed first to determine the data of interest.
- WHERE. The WHERE clause is executed to filter out records that do not meet the constraints.
- GROUP BY.
- HAVING.
- SELECT.
- ORDER BY.
- LIMIT/OFFSET.
How to ORDER BY 2 conditions in SQL
After the ORDER BY keyword, add the name of the column by which you'd like to sort records first (in our example, salary). Then, after a comma, add the second column (in our example, last_name ). You can modify the sorting order (ascending or descending) separately for each column.For example,
- — orders all rows from Customers in ascending order by age SELECT * FROM Customers ORDER BY age ASC;
- — order all rows from Customers in descending order by age SELECT * FROM Customers ORDER BY age DESC;
GROUP BY and ORDER BY Explained
The purpose of the ORDER BY clause is to sort the query result by one or more columns. Meanwhile, the GROUP BY clause is used to arrange data into groups with the help of aggregate functions such as COUNT(), AVG, MIN() and MAX().

How do I run SQL jobs sequentially : One way to accomplish what you are after is to simply use sp_start_job stored procedure.
- On each job add a tsql job step.
- Make sure it is the last step.
- Then have it execute the code below. EXEC msdb.dbo.sp_start_job N'Name of Next Job to Start'
Can you use ORDER BY and WHERE together in SQL : You can use the WHERE clause with or without the ORDER BY statement.
What are the 5 basic SQL commands

The ORDER BY clause specifies the particular order in which you want selected rows returned. The order is sorted by ascending or descending collating sequence of a column's or an expression's value. The result follows. Note: Null values are ordered as the highest value.When using ORDER BY 1, 2, 3 , we're instructing the database to sort the results based on the first, second, and third columns in the SELECT list. ORDER BY 2 DESC , 3 DESC , 1 ASC ; Now, we're instructing the database to group the results based on the second, third, and first column in the SELECT list.
How to use multiple ORDER BY in MySQL : ORDER BY with multiple columns example
The query syntax will then include the list of columns separated by commas in ORDER BY: ORDER BY column1, column2; We want to sort results using the “MySQL ORDER BY two columns” scenario. The system will sort the results by column1, then by column2, all in ascending order.
