How Can I Find MySQL Tables Containing Specific Column Names?

Finding MySQL Tables with Specific Column Names

Often, developers need answers about their database schema. Looking through it manually can be time-consuming. One such query is to search for tables containing a specific column. This article will cover a simple method to retrieve a list of all MySQL tables with specified column names.

Identifying Tables

To identify all tables with given column names (e.g., "columnA" or "ColumnB") in the "YourDatabase" database, use the following SQL query:

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

This query utilizes the INFORMATION_SCHEMA.COLUMNS table to obtain information about all columns in the database. The WHERE clause filters the results to include only columns with the desired names and tables belonging to the specified database. The DISTINCT keyword ensures that each table is listed only once.

By executing this query, developers can quickly identify all MySQL tables that contain the specified column names, aiding in schema analysis, data querying, and other database management tasks.
