Hi Experts,
I have used Aasim Abdullah's (below link) stored procedure for dynamically generate code for deletion of child tables based on parent with certain filter condition. But I am getting a output which is not proper (Query 1). I would like to have output mentioned in Query 2.
Link:
--[Patient] is the Parent table, [Case] is child table and [ChartInstanceCase] is grand child
--When I am deleting a grand child table, it should be linked to child table first followed by Parent
--- query 1
DELETE Top(100000) FROM [dbo].[ChartInstanceCase]
FROM [dbo].[Patient] INNER JOIN [dbo].[Case] ON [Patient].[PatientID] = [Case].[PatientID]
INNER JOIN [dbo].[ChartInstanceCase] ON [Case].[CaseID] = [ChartInstanceCase].[CaseId]
WHERE [Patient].PracticeID = '55';
--Query 2
DELETE Top(100000) [dbo].[ChartInstanceCase]
FROM [dbo].[ChartInstanceCase] INNER JOIN [dbo].[Case] ON [ChartInstanceCase].[CaseId]=[Case].[CaseID]
INNER JOIN [dbo].[Patient] ON [Patient].[PatientID] = [Case].[PatientID]
WHERE [Patient].PracticeID = '55';
Please do let me know how to modify the SP 'dbo.uspCascadeDelete' to get the output as Query 2
Please help.
Thanks,
Naveen

A couple challenges here. First I don't want to go read another thread somewhere else so I can help you. Secondly you mention output but there is no output from either query you posted. They are both delete statements with no output clause. I assume you must mean that it is not doing what you want? The best way to get some help is to provide us the details so we can help you. Please take a few minutes and read the first article in my signature for best practices when posting questions.
