How to Count Rows in a MySQL Table?

Determining Table Row Count in MySQL

MySQL provides a convenient method to retrieve the number of records stored in a database table. This is often useful for various scenarios such as performance monitoring, data validation, and statistical analysis.

To retrieve the count of rows in a table in MySQL, you can utilize the COUNT(*) function. This function calculates the number of rows within a specified table, regardless of any filtering criteria. The syntax for this command is:

SELECT COUNT(*) FROM <table_name>;
Copy after login

For example, let's assume we have a table called fooTable and we want to count the number of rows it contains. We would use the following query:

SELECT COUNT(*) FROM fooTable;
Copy after login

When executed, this query will return a single row with a column named COUNT(*) that displays the count of rows in the fooTable table.

It's important to note that COUNT(*) includes all rows in the table, even those that may contain null values. If you want to exclude null values from the count, you can use the COUNT(column_name) syntax instead, where column_name is a non-null column in the table.

For more information on row counting in MySQL, refer to the official MySQL documentation.

How does MySQL index cardinality affect query performance? How does MySQL index cardinality affect query performance? Apr 14, 2025 am 12:18 AM

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
