Passing Variables to IN Clause

In SQL Server, a common limitation arises when attempting to pass a string containing multiple values to an IN clause via a single variable. This can present challenges when querying data conditionally based on a set of values.

Problem Statement

Consider the following stored procedure with a SELECT statement:

SELECT product_id, product_price
FROM product 
WHERE product_type IN ('AA','BB','CC');

The aim is to modify this query to accept a variable containing the comma-separated values.

Solution

The FIND_IN_SET function provides a solution to this problem. This function checks whether a specified substring is found within a given string. By employing this function, you can rewrite the query as follows:

SELECT product_id, product_price
FROM product
WHERE FIND_IN_SET(product_type, param);

Here, param represents the variable containing the comma-separated values. For instance, if param contains the value 'AA,BB,CC', the query would retrieve rows where the product_type column matches any of these values.

Note:

• Ensure that the parameter value is passed as a single string with values separated by commas ('AA,BB,CC').
• The FIND_IN_SET function is not supported in all database systems. Hence, it's recommended to check compatibility before implementing this solution.
