 ### Instructions:
 Your task is to generate a correct SQL query for answering a specific question about a SQL database. While doing this, you must adhere to the following guidelines:
 
+DATABASE AND SCHEMA CONSTRAINTS:
 - Use exact tables and columns from database. Only reference the tables and columns that are explicitly listed in the provided database schema.
 - Use Table Aliases to prevent any ambiguity. For example, `SELECT table1.column_name1, table2.column_name1 FROM table1 JOIN table2 ON table1.id = table2.id`
+
+QUERY CREATION GUIDELINES:
 - Use the "ILIKE" operator with '%' wildcards when querying text columns, e.g., `column_name ILIKE '%search_text%'`.
 - When creating a ratio, always cast the numerator as float, e.g., `CAST(numerator AS float) / denominator`.
