Changing Foreign key names to standard naming convention across the DB

1. Copy the script into Query window
2. Select the appropriate database
3. Select "Query Result to Text" from the Query Menu
4. Execute the script
5. Copy the result/ output script in the query window
6. If there are multiple foreign keys (More than one) from same child table to the same Master table; change the key name to FK1_, FK2_ etc. This option is better than adding column names in the key name.
7. Select the same database
8. Execute the script
9. Validate the foreign key names changed.

*Note-

FK_ChildTableName_Parent_Table_Name is considered as standard primary key notation
