Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE Ref_Colors ( color_code VARCHAR(15), color_description VARCHAR(80) )
TABLE: CREATE TABLE Products ( product_id INTEGER, color_code VARCHAR(15), product_category_code VARCHAR(15), product_name VARCHAR(80), typical_buying_price VARCHAR(20), typical_selling_price VARCHAR(20), product_description VARCHAR(255), other_product_details VARCHAR(255) )
TABLE: CREATE TABLE Ref_Characteristic_Types ( characteristic_type_code VARCHAR(15), characteristic_type_description VARCHAR(80) )
TABLE: CREATE TABLE Characteristics ( characteristic_id INTEGER, characteristic_type_code VARCHAR(15), characteristic_data_type VARCHAR(10), characteristic_name VARCHAR(80), other_characteristic_details VARCHAR(255) )
TABLE: CREATE TABLE Product_Characteristics ( product_id INTEGER, characteristic_id INTEGER, product_characteristic_value VARCHAR(50) )
TABLE: CREATE TABLE Ref_Product_Categories ( product_category_code VARCHAR(15), product_category_description VARCHAR(80), unit_of_measure VARCHAR(20) )

### Question ###
What are the descriptions of the categories that products with product descriptions that contain the letter t are in, and count them by a pie chart

### Accurate SQL ###

SELECT product_category_description, COUNT(product_category_description) FROM Ref_Product_Categories AS T1 JOIN Products AS T2 ON T1.product_category_code = T2.product_category_code WHERE T2.product_description LIKE '%t%' GROUP BY product_category_description
