How to Use MySQL's WHERE IN Clause with an Array of IDs?

Using WHERE IN Clause to Query MySQL with Array

Given an array of IDs, the goal is to construct a SQL query that checks the values in the WHERE clause using the array values.

To generate the query string, follow these steps:

Step 1: Create the Base Query

SELECT *
FROM galleries

Step 2: Append the WHERE Clause with IN Operator

WHERE id IN (?,?,?,...)

• The number of question marks соответствует the length of the array.

Step 3: Parameterize the Values

• Prepare the SQL statement using a prepared statement or parameterized query.
• Bind the array values to the question marks as parameters.

Example:

• Array: $galleries = array(1,2,5)

SQL Query:

SELECT *
FROM galleries
WHERE id IN (:id1, :id2, :id3)

• :id1, :id2, :id3 are named parameters.

Step 4: Execute the Query

• Execute the prepared statement with the array values bound as parameters.
