The steps to execute SQL queries in phpMyAdmin are as follows: 1. Open the SQL window, select the target database and click the "SQL" button at the top; 2. Enter SQL statements in the text box, support multiple statements and separate them with semicolons or newlines; 3. Click the "Execute" button or use the shortcut key Ctrl Enter to run the statement, and the results will be displayed in a form or affecting the number of rows; 4. You can save common queries by checking "Create Bookmark" for subsequent quick calls; precautions include ensuring account permissions, avoiding syntax errors, be sure to add WHERE conditions when performing updates or deletion operations, and recommending backup data before important operations.

Executing SQL queries in phpMyAdmin is actually quite simple. As long as you are familiar with its interface and basic operations, you can quickly complete database query, modification and other tasks. Next, I will explain step by step how to use it to execute SQL statements.

Open a SQL window

First, select the database you want to operate on the left side of the phpMyAdmin main interface. After entering the database, find the "SQL" button in the top menu bar. Click in and you will see a large text box. This is where SQL query is executed.

You can write your SQL statement directly in this box, such as:

 SELECT * FROM users;

You can also execute multiple statements at once, just break lines or add semicolons between each one.

Enter and run SQL statements

After entering the statement, click the "Execute" button (or the shortcut Ctrl Enter) at the bottom of the page, and the system will start running your SQL commands and display the results below.

If you are writing a SELECT query, the results will be displayed in a table; if it is UPDATE or DELETE operation, the number of affected rows will be prompted.

Tips: phpMyAdmin will automatically format SQL for you. It doesn’t matter if the statements you write are not indented, but it is recommended to maintain a clear structure to facilitate checking errors.

Use the bookmark function to save common queries (optional)

If you often need to execute certain fixed SQL queries, such as counting data for a certain time period, you can check "Create Bookmark" below the SQL input box to name this statement and save it.

Next time you want to execute, click the "Bookmark" tab at the top to see all the statements you saved before, and you can run them directly with just one click. This function is very helpful for frequent operations.

Notes and FAQs

• Permissions issue : Not all users have the right to perform arbitrary SQL, especially to delete or modify data operations. Pay attention to account permissions.
• Syntax error : If SQL is written incorrectly, phpMyAdmin will generally prompt where an error occurs and can be modified accordingly.
• Influence range : When executing UPDATE or DELETE , you must add WHERE conditions, otherwise the entire table data may be deleted by mistake.
• Backup suggestions : It is best to do an export backup before important operations to avoid data loss due to incorrect operations.

Basically all that is it. The whole process is not complicated, but it is easy to have problems due to carelessness. As long as you pay attention to the correctness of the statement and operation permissions, you can use phpMyAdmin to execute SQL queries with peace of mind.
