How to 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 DB and list out all tables which have those columns. Any easy script?

Answer 1

If you want "To get all tables only", Then use this query:

SELECT TABLE_NAME 
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME like '%'
and TABLE_SCHEMA = 'tresbu_lk'

If you want "To get all tables with Columns", Then use this query:

SELECT DISTINCT TABLE_NAME, COLUMN_NAME  
FROM INFORMATION_SCHEMA.COLUMNS  
WHERE column_name LIKE '%'  
AND TABLE_SCHEMA='tresbu_lk'

Answer 2

SELECT DISTINCT TABLE_NAME, COLUMN_NAME  
FROM INFORMATION_SCHEMA.COLUMNS  
WHERE column_name LIKE 'employee%'  
AND TABLE_SCHEMA='YourDatabase'

Answer 3

SELECT TABLE_NAME, COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME LIKE '%wild%';

Answer 4

SELECT DISTINCT TABLE_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME LIKE '%city_id%' AND TABLE_SCHEMA='database'

Answer 5

More simply done in one line of SQL:

SELECT * FROM information_schema.columns WHERE column_name = 'column_name';

Answer 6

Use this one line query, replace desired_column_name by your column name.

SELECT TABLE_NAME FROM information_schema.columns WHERE column_name = 'desired_column_name';
