Im currently trying to move data from one table to another. In a previous question I asked today I was advised to use an insert statement. While trying to run the statement i get an error from SQL Server as follows:

Cannot insert the value NULL into column 'Parent', table '*****.dbo.Product'; column does not allow nulls. INSERT fails.

This is the statement I have created,

BEGIN TRANSACTION
INSERT INTO [*****].[dbo].[Product] 
([PDate]
  ,[SDate]
  ,[CreatedBy]
  ,[CreatedDate]
  ,[UpdatedBy]
  ,[UpdatedDate])
SELECT d.[PDate]
  ,d.[SDate]
  ,d.[CreatedBy]
  ,d.[CreatedDate]
  ,d.[UpdatedBy]
  ,d.[UpdatedDate]
FROM [*****].[dbo].[ProductData] AS d
JOIN [*****].[dbo].[Product] AS t
ON d.ProductDataID = t.ProductDataID
ROLLBACK TRANSACTION

I need to ensure that the data matches up correctly

Edit: Sorry, there was an error when i was copying the script. UseDRM is in both sections of my original script. What I want to do is to copy the data in the ProductData table to the Product table.

The Parent column is not nullable and has not default value, so you need to add it to your query.

Try using ISNULL in you select query to check if the value is null & replace it with default value.

Eg.:

   BEGIN TRANSACTION
    INSERT INTO [*****].[dbo].[Product] 
    ([PDate]
      ,[SDate]
      ,[UseDRM]
      ,[CreatedBy]
      ,[CreatedDate]
      ,[UpdatedBy]
      ,[UpdatedDate])
    SELECT Isnull(d.[PDate], '1/1/1900')
      ,Isnull(d.[SDate], '1/1/1900')
      ,Isnull(d.[UseDRM], "")
      ,Isnull(d.[CreatedBy], "")
      ,Isnull(d.[CreatedDate], '1/1/1900')
      ,Isnull(d.[UpdatedBy], "")
      ,Isnull(d.[UpdatedDate], '1/1/1900')
    FROM [*****].[dbo].[ProductData] AS d
    JOIN [*****].[dbo].[Product] AS t
    ON d.ProductDataID = t.ProductDataID
    ROLLBACK TRANSACTION

BEGIN TRANSACTION
INSERT INTO [*****].[dbo].[Product] 
([PDate]
  ,[SDate]//Check Columns no here it is  6 total
  ,[CreatedBy]
  ,[CreatedDate]
  ,[UpdatedBy]
  ,[UpdatedDate])
SELECT d.[PDate] //Check columns numbers here it is 7 here 
  ,d.[SDate]
  ,d.[UseDRM]
  ,d.[CreatedBy] 
  ,d.[CreatedDate]
  ,d.[UpdatedBy]
  ,d.[UpdatedDate]
FROM [*****].[dbo].[ProductData] AS d
JOIN [*****].[dbo].[Product] AS t
ON d.ProductDataID = t.ProductDataID
ROLLBACK TRANSACTION

correct it then it will be ok d.[UseDRM] is not in insert

I finally figured out what i was doing wrong, instead of using an INSERT INTO statement I should have been using an UPDATE statement

UPDATE [********].[dbo].[Product] 
SET [PDate] = [********].[dbo].[ProductData].[PDate]
  ,[SDate] = [********].[dbo].[ProductData].[SDate]
  ,[CreatedBy] = [********].[dbo].[ProductData].[CreatedBy]
  ,[CreatedDate] = [********].[dbo].[ProductData].[CreatedDate]
  ,[UpdatedBy] = [********].[dbo].[ProductData].[UpdatedBy]
  ,[UpdatedDate] = [********].[dbo].[ProductData].[UpdatedDate]
FROM [********].[dbo].[ProductData], [********].[dbo].[Product]
WHERE [********].[dbo].[Product].[ProductDataID] = [********].[dbo].[ProductData].[ProductDataID]

I apologise for my orginial question which is poorly written
