CAST 0 as DateTime

Question

How do you cast 0 as DateTime?  Is this possible to do...
I am using UNION to combine two tables.  I get an error when doing so...
Msg 206, Level 16, State 2, Line 1
Operand type clash: int is incompatible with date
SELECT TOP (100) PERCENT
Opportunity_Name
,Status
,Closed_Status
,Sales_Stage
,Expected_Close_Date
,Closed_Flag
,Total_Revenue
FROM
v_rpt_Opportunity
WHERE
(Expected_Close_Date >= DATEADD(MM, DATEDIFF(MM, 0, GETDATE()), 0))
UNION
SELECT TOP (100) PERCENT
0 AS Opportunity_Name
,0 AS Status
,0 AS Closed_Status
,Description AS 'Sales_Stage'
,0 AS Expected_Close_Date
,0 AS Closed_Flag
,0 AS Total_Revenue
FROM SO_Pipeline
WHERE Description NOT LIKE '%delete%'
I understand what is causing the error.  In the top select statement both Closed_Status AND Expected_Close_Date are datetime values.  But in the bottom statement they are int.

I tried CASTing them as datetime, that didn’t work and I get this error.<o:p></o:p>
Conversion
failed when converting the varchar value 'Open' to data type int.
Is there a way to CAST 0 as a DateTime
Thank you,

I think the issue is not with the dates, instead it's with either Status / Closed Status i.e. one of their value is “open” and error is when that value to “int” which is not possible. Try
casting them to varchars.
SELECT TOP (100) PERCENT
Opportunity_Name
,Status
,Closed_Status
,Sales_Stage
,Expected_Close_Date
,Closed_Flag
,Total_Revenue
FROM
v_rpt_Opportunity
WHERE
(Expected_Close_Date >= DATEADD(MM, DATEDIFF(MM, 0, GETDATE()), 0))
UNION
SELECT TOP (100) PERCENT
0 AS Opportunity_Name
,CAST(0 AS VARCHAR(10)) AS Status
,CAST(0 AS VARCHAR(10)) AS Closed_Status
,Description AS 'Sales_Stage'
,0 AS Expected_Close_Date
,0 AS Closed_Flag
,0 AS Total_Revenue
FROM SO_Pipeline
WHERE Description NOT LIKE '%delete%'
