Hi,

I have created a few tables into a DB.
For some reason I need to remove all the tables I have created.
I have removed all the tables except one.

I am getting an error like this while trying the sql

delete from MappedRuleSet

Msg 547, Level 16, State 0, Line 1
The DELETE statement conflicted with the REFERENCE constraint "MappedRuleSet_TitleFilePartMapping_FK1". The conflict occurred in database "SS_TEST", table "dbo.TitleFilePartMapping", column 'MappingRuleSetID'.
The statement has been terminated.

Regards

ya surely this will give error because u hve connected  many tables with each other .. since u hve used table columns from  more than one table in one table surely it will give error .. this has only one soltuion tht u shuld make remove constraint from it .. then del the table u want..

Hi,

You no need to drop constraint.
if you already delete data from TitleFilePartMapping then you can u delete from MappedRuleSet.

Hi la-tempestad,

The TitleFilePartMapping table has a column MappingRuleSetID that is a foreign key back to the table you need to delete. You will have to either:
1. Remove the data in TitleFilePartMapping that is related to data in the MappedRuleSet table using a statement such as this

delete from dbo.TitleFilePartMapping where mappedrulesetid = (select id from MappedRuleSet)

OR

2. Remove the foreign key before deleting the MappedRuleSet table using a statement such as this:

ALTER TABLE dbo.TitleFilePartMapping
DROP CONSTRAINT MappedRuleSet_TitleFilePartMapping_FK1

Hope this helps you. Please let us know if we can assist further.

Table "TitleFilePartMapping" is child Table and MappedRuleSet is Master Table.

So its advised that you should not delete data from MappedRuleSet, if u dont want to delete data from "TitleFilePartMapping"

Still if u want to drop constraint then
Open Management Studio
Select DataBase
Select Table -TitleFilePartMapping
expand the table by clicking on +

Select Key and then select MappedRuleSet_TitleFilePartMapping_FK1

RIGHT CLICK AND REMOVE
