Hi, I have the following SQL scripts. I want to INNER JOIN a table from another table, but seems like it cant as when I execute the query, it returns me some error as below:

C#

The multi-part identifier "ProductDetail.RelationId" could not be bound.

Below is my SQLscript:

SQL

SELECT
	 cd.CustomerName	
	,cd.CustomerAddress 
	,pr.ProductName
FROM
	CustomerDetail AS cd
	INNER JOIN ProductRelation as pr
		ON pr.RelationId = ProductDetail.RelationId

For some logic reason, I cannot remove the CustomerDetail table. But is there anyway I can join ProductRelation and ProductDetail table together?

Solution 1

Check your FROM Clause you have used CustomerDetail and ProductRelation, so from where ProductDetail alias comes?

Try this

SQL

SELECT
	 cd.CustomerName	
	,cd.CustomerAddress 
	,pr.ProductName
FROM
	CustomerDetail AS cd
	INNER JOIN ProductRelation as pr
		ON pr.RelationId = cd.RelationId

Thank you for your suggestion sir. But unfortunately, in the CustomerDetail table do not have RelationId.

so how can we turn this unfortunate event to fortune? :)

Yes sir, fortune sure has come. I have use another table to join with CustomerDetail table before ProductRelation table. Then only I will use the value in the other table to continue to join back the ProductRelation table and subsequently ProductDetail table. :)
