information schema - How can I find all the tables in MySQL with specific column names in them?

Question

I have 2-3 different column names that I want to look up in the entire database and list out all tables which have those columns. Is there any easy script?

Answer 1

To get all tables with columns columnA or ColumnB in the database YourDatabase:

SELECT DISTINCT TABLE_NAME 
    FROM INFORMATION_SCHEMA.COLUMNS
    WHERE COLUMN_NAME IN ('columnA','ColumnB')
        AND TABLE_SCHEMA='YourDatabase';
