How to find the number of records that satisfy a condition in SQLite?

To retrieve the number of records that meet the conditions, you can use the COUNT function in SQLite. Below is the query method:

SELECT COUNT(*) FROM 表名 WHERE 条件;

`COUNT(*)` is used to calculate the total number of records that meet the conditions.

– `Table name` is the name of the table that needs to be queried.

`WHERE` is optional and is used to specify the query conditions.

For example, consider a table named `employees` that contains employee information. To query the number of records that meet a certain condition (such as being over 30 years old), you can use the following query statement:

SELECT COUNT(*) FROM employees WHERE age > 30;

Please replace the table name and condition section with your actual circumstances.
