Question

Im using a DB2 Database. What would be a suitable SQL query to find out if a column is exists in a table or list of tables?

e.g

if "column_name" is found in "table name" or [list of table names]

return true or the name of tables that have that column.

Many thanks.

Use SYSCAT.COLUMNS catalog view:

SELECT TABNAME
FROM SYSCAT.COLUMNS
WHERE 
    TABNAME IN ('table name 1', 'table name 2') AND 
    COLNAME = 'column_name';
