Solution 1 - you will have to delete foreign key occurence of the data first and then delete primary key occurence or you'll get reference error which I think you are facing currently,

SELECT 
    FK_Table  = FK.TABLE_NAME, 
    FK_Column = CU.COLUMN_NAME, 
    PK_Table  = PK.TABLE_NAME, 
    PK_Column = PT.COLUMN_NAME,

WHERE PK.TABLE_NAME='something'

WHERE FK.TABLE_NAME='something'

WHERE PK.TABLE_NAME IN ('one_thing', 'another')

WHERE FK.TABLE_NAME IN ('one_thing', 'another')

select distinct data,<br />
