Question

Why is this query not working?

Delete  tblProduct
From    tblProduct
Inner Join @unwantedRows
On tblProduct.ProductId = @unwantedRows.ProductId;

Where @unwantedRows is

DECLARE @unwantedRows TABLE 
( 
    ProductId INT, 
    ProductName VARCHAR(50),
    Description VARCHAR(50),
    Category VARCHAR(50),
    Repetitions int

);

Answer 1

You can’t use the variable name in the join like that.

Try:

Delete  tblProduct
From    tblProduct
Inner Join @unwantedRows AS u
On tblProduct.ProductId = u.ProductId;
