Here is a Sql Fiddle that proves the below query

You can get the tables from this query:

SELECT Name, IsChecked = 0
INTO #Tables
FROM sys.Tables
WHERE EXISTS
(
  SELECT * FROM sys.columns 
  WHERE object_id = OBJECT_ID(sys.Tables.Name) AND sys.columns.Name = 'blah'
) 

Then, you can create a dynamic query and execute it for the tables that you found

WHILE(SELECT COUNT(*) FROM #Tables WHERE IsChecked = 0) > 0
BEGIN
    SELECT TOP 1 @TableName = Name FROM #Tables WHERE IsChecked = 0
    SET     @DeleteQuery = 'DELETE FROM ' + @TableName  + ' WHERE CorporationID = ''' + @CorporationId + ''''
    EXECUTE sp_executeSQL @DeleteQuery;
    UPDATE #Tables SET IsChecked = 1 WHERE Name = @TableName 
END
