Passing Variables to IN Clauses

Background:

In SQL, the IN clause allows you to compare a column's value to a set of values. In certain scenarios, you may want to pass a variable containing a list of values to the IN clause dynamically.

Problem:

You have an SP with a SELECT statement that uses an IN clause to filter results based on specific values from a list. However, you need to pass the list of values as a single variable rather than specifying them individually.

Solution:

To pass a variable to an IN clause, consider using the FIND_IN_SET function. This function takes two parameters:

1. The column you want to compare against (product_type in this case)
2. A string containing the comma-separated list of values (e.g., 'AA,BB,CC')

Modified Query:

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

Passing Parameter Value:

When calling the SP, pass the comma-separated list of values as the value of the 'param' variable. For instance:

EXEC SP @param = 'AA,BB,CC'

Explanation:

The FIND_IN_SET function returns 1 if the specified column value is found in the comma-separated list, and 0 otherwise. By using this function, you can dynamically filter the results based on the values passed in the 'param' variable.
