Unable to delete the table due to SQL Resolution, prompting that the table is referenced by a foreign key constraint

The SQL statement cannot be used to delete a table. The system prompts that the table is referenced by a foreign key constraint. For more information, see.

The SQL statement cannot be used to delete a table. The system prompts that the table is referenced by a foreign key constraint. For more information, see.

The Drop table command is used to delete all rows in a table or table. The syntax format is:

Drop table "tablename"

The following is an example:

Drop table employee;

To delete the entire table (including all rows), you can use the drop table command and add tablename. The Drop table command is different from deleting all records in the table:

The prompt "the object 'Orders cannot be deleted because the object is being referenced by a foreign key constraint" is displayed. The reason is that the object cannot be deleted because it is referenced by FOREIGN keys of other tables, in this case, you only need to find the tables whose Foreign keys reference the fields of the table. System functions can be used to solve (SQL Server system functions provide excellent functions that can replace us in finding and solving many problems ).

The Code is as follows:
Select Fk. name, fk. object_id, OBJECT_NAME (fk. parent_object_id) as referenceTableName From sys. foreign_keys as fk Join sys. objects as o on fk. referenced_object_id = o. object_id Where o. name = 'referenced table name'

The preceding SQL statement can obtain the foreign key references to a table and display the table name of the foreign key table. You can delete a foreign key by executing the following statement using the table name and foreign key name of the foreign key table.

Alter table dbo. Name of the referenced table drop constraint foreign key name
