How to write alphabetical order in sql
How to sort alphabetically in SQL: Sort in ascending order: Use the ORDER BY clause followed by the column name and ASC (ascending order). Sort descending: Use the ORDER BY clause, followed by the column name and DESC (descending). Multi-column sorting: Use comma-separated sorting columns, each followed by the sorting order (ASC or DESC). Applies to string data types; numeric types can be sorted in ascending/descending order.
How to sort alphabetically using SQL
To sort data alphabetically in SQL, you can use ORDER BY clause. This clause allows you to specify the column to be sorted and whether to sort in ascending or descending order.
Sort in ascending order
To sort a column in ascending order (from A to Z), use the following syntax:
SELECT column_name FROM table_name ORDER BY column_name ASC;
For example, press name Sort columns in ascending order:
SELECT name FROM customers ORDER BY name ASC;
Sort in descending order
To sort a column in descending order (from Z to A), use the following syntax:
SELECT column_name FROM table_name ORDER BY column_name DESC;
For example, to sort by the name column in descending order:
SELECT name FROM customers ORDER BY name DESC;
Multiple sort columns
You can sort by multiple columns Sort, for example, first by one column in ascending order and then by another column in descending order. To do this, use a comma to separate each sort column and its sort order (ASC or DESC).
For example, first sort by the state column in ascending order, and then sort by the name column in descending order:
SELECT * FROM customers ORDER BY state ASC, name DESC;
Notes
- Alphabetical sorting only applies to string data types.
- For numeric types, you can use
ORDER BY column_name 0to sort in ascending or descending order. - If a column contains null values, these values will be considered smaller than non-null values.
-
The ORDER BYclause can also be used to sort by other criteria, such as dates or numbers.

Optimizing SQL ORDER BY for Query Performance
Aug 04, 2025 am 11:19 AM
To optimize the performance of ORDERBY in SQL, you must first understand its execution mechanism and make rational use of index and query structure. When the sorting field has no index, the database will trigger "filesort", consuming a lot of resources; therefore, direct sorting of large tables should be avoided and the amount of sorted data should be reduced through WHERE conditions. Secondly, establishing a matching index for sorting fields can greatly speed up queries, such as creating reverse order indexes in MySQL 8.0 to improve efficiency. In addition, deep paging (such as LIMIT1000, 10) should be used instead with index-based cursor paging (such as WHEREid>12345) to skip invalid scans. Finally, combining caching, asynchronous aggregation and other means can also further optimize the sorting performance in large data set scenarios.
Understanding SQL Execution Context and Permissions
Aug 16, 2025 am 08:57 AM
SQL execution context refers to the identity or role when running SQL statements, which determine which resources and operation permissions can be accessed. Permission setting should follow the principle of minimum permissions, and common permissions include SELECT, INSERT, EXECUTE, etc. To troubleshoot permission issues, you need to confirm the login name, role permissions, EXECUTEAS settings and schema authorization. Performing context switching can be implemented through EXECUTEAS, but attention should be paid to user existence, permission granting and performance security impact. It is recommended to avoid arbitrarily assigning db_owner or sysadmin roles. The application account should only access necessary objects and be authorized through schema.
