How Can I Check for Table Existence in MySQL Without Using `SELECT FROM`?

Determine the existence of a table in MySQL without "SELECT FROM" syntax

When dealing with MySQL, it's crucial to have a way to check if a table exists without the regular "SELECT FROM" method.

Background

While it is a common practice to use "SELECT testcol FROM testtable" and check the returned field count, there is a more elegant and direct way.

Solution: INFORMATION_SCHEMA

The most accurate way is to use INFORMATION_SCHEMA:

<code class="language-sql">SELECT * 
FROM information_schema.tables
WHERE table_schema = 'yourdb' 
    AND table_name = 'testtable'
LIMIT 1;</code>

If the query produces any rows, the table exists.

Alternative: SHOW TABLES

Alternatively, you can take advantage of SHOW TABLES:

<code class="language-sql">SHOW TABLES LIKE 'yourtable';</code>

Similarly, the presence of a row in the result set indicates the existence of the table.
