Re: Report with data from 2 unrelated siblings

I know you can do this in SQL, but it's Friday and I'm too tired to work it out again :)

Tamar is a great authority on SQL (she wrote a book on it!) and I know she wrote several articles on unrelated siblings. Here's one:

and you might poke around on her website for others.

Hi,

CREATE CURSOR Merchants ; (MerchantID i,; MerchantName c(10))

INSERT INTO Merchants (MerchantID, MerchantName) VALUES (1, "Freddie") INSERT INTO Merchants (MerchantID, MerchantName) VALUES (2, "Brian") INSERT INTO Merchants (MerchantID, MerchantName) VALUES (3, "Roger") INSERT INTO Merchants (MerchantID, MerchantName) VALUES (4, "John")

CREATE CURSOR Emails; (EmailID i,; MerchantID i,; Email c(30))

INSERT INTO Emails (EmailId, MerchantID, Email) VALUES (1, 2, "brian@queen.com") INSERT INTO Emails (EmailId, MerchantID, Email) VALUES (2, 2, "brian@gmail.com") INSERT INTO Emails (EmailId, MerchantID, Email) VALUES (3, 4, "john@queen.com")

CREATE CURSOR Templates ; (TemplateID i,; TemplateName c(10))

INSERT INTO Templates (TemplateID, TemplateName) VALUES (1, "template 1") INSERT INTO Templates (TemplateID, TemplateName) VALUES (2, "template 2")

CREATE CURSOR MerchantTemplates; (MerchantTemplateID i,; MerchantID i,; TemplateID i)

INSERT INTO MerchantTemplates (MerchantTemplateID, MerchantID, templateID) VALUES (1, 2, 1) INSERT INTO MerchantTemplates (MerchantTemplateID, MerchantID, templateID) VALUES (2, 2, 2) INSERT INTO MerchantTemplates (MerchantTemplateID, MerchantID, templateID) VALUES (3, 4, 1) INSERT INTO MerchantTemplates (MerchantTemplateID, MerchantID, templateID) VALUES (4, 4, 2)

I need to create a report like this (the email and template columns must be side by side): *Merchant**

•   *Email**
  

•   *Template*
  

Freddie

Brian brian@queen.com Template 1 Brian brian@gmail.com Template 2 Roger

John john@queen.com Template 1 John

    Template 2

This was my attempt to build the data, but I get doubling up:

SELECT MerchantName; ,Email; ,TemplateName ; FROM Merchants ; LEFT JOIN Emails ON Merchants.MerchantID = Emails.MerchantID; LEFT JOIN MerchantTemplates ON Merchants.MerchantID = MerchantTemplates.MerchantID; LEFT JOIN Templates ON MerchantTemplates.TemplateId = Templates.TemplateID

Can I do this in SQL or do I need to build my cursor up procedurally?
