How to Retrieve the Current AUTO_INCREMENT Value in MySQL?

Retrieving the Current AUTO_INCREMENT Value for MySQL Tables

One of the key features of MySQL tables is the ability to automatically increment an integer value for each new row inserted. This value is known as the AUTO_INCREMENT value and is widely used to create unique identifiers or timestamps. However, there may be scenarios where you need to retrieve the current AUTO_INCREMENT value for a specific table.

Using SHOW TABLE STATUS Query

MySQL provides the SHOW TABLE STATUS query to display information about tables, including their auto-increment values. To retrieve the AUTO_INCREMENT value for a table named "TableName" in a database "DatabaseName," execute the following query:

SHOW TABLE STATUS FROM `DatabaseName` WHERE `name` LIKE 'TableName' ;

This query will return a table containing various information about the "TableName" table, including the Auto_increment column that displays the current AUTO_INCREMENT value.

Using INFORMATION_SCHEMA.TABLES Query

Alternatively, you can use the INFORMATION_SCHEMA.TABLES system table to specifically extract the AUTO_INCREMENT value. This approach is more precise and provides a direct way to access the value. Execute the following query:

SELECT `AUTO_INCREMENT`
FROM  INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'DatabaseName'
AND   TABLE_NAME   = 'TableName';

This query will directly retrieve the AUTO_INCREMENT value for the specified "TableName" table in the "DatabaseName" database.
