How to create Temp table with SELECT * INTO tempTable FROM CTE Query

SqlSql ServerCommon Table-Expression

Sql Problem Overview


I have a MS SQL CTE query from which I want to create a temporary table. I am not sure how to do it as it gives an Invalid Object name error.

Below is the whole query for reference

SELECT * INTO TEMPBLOCKEDDATES FROM 
;with Calendar as (
    select EventID, EventTitle, EventStartDate, EventEndDate, EventEnumDays,EventStartTime,EventEndTime, EventRecurring, EventStartDate as PlannedDate
    ,EventType from EventCalender
    where EventActive = 1 AND LanguageID =1 AND EventBlockDate = 1
    union all
    select EventID, EventTitle, EventStartDate, EventEndDate, EventEnumDays,EventStartTime,EventEndTime, EventRecurring, dateadd(dd, 1, PlannedDate)
    ,EventType from Calendar
    where EventRecurring = 1
        and dateadd(dd, 1, PlannedDate) <= EventEndDate 
)
select EventID, EventStartDate, EventEndDate, PlannedDate as [EventDates], Cast(PlannedDate As datetime) AS DT, Cast(EventStartTime As time) AS ST,Cast(EventEndTime As time) AS ET, EventTitle
,EventType from Calendar
where (PlannedDate >= GETDATE()) AND ',' + EventEnumDays + ',' like '%,' + cast(datepart(dw, PlannedDate) as char(1)) + ',%'
    or EventEnumDays is null
order by EventID, PlannedDate
option (maxrecursion 0)

I would appreciate a point in the right direction or if I can create a temporary table from this CTE query

Solution 1 - Sql

Sample DDL

create table #Temp
(
	EventID int, 
	EventTitle Varchar(50), 
	EventStartDate DateTime, 
	EventEndDate DatetIme, 
	EventEnumDays int,
	EventStartTime Datetime,
	EventEndTime DateTime, 
	EventRecurring Bit, 
    EventType int
)

;WITH Calendar
AS (SELECT /*...*/)

Insert Into #Temp
Select EventID, EventStartDate, EventEndDate, PlannedDate as [EventDates], Cast(PlannedDate As datetime) AS DT, Cast(EventStartTime As time) AS ST,Cast(EventEndTime As time) AS ET, EventTitle
,EventType from Calendar
where (PlannedDate >= GETDATE()) AND ',' + EventEnumDays + ',' like '%,' + cast(datepart(dw, PlannedDate) as char(1)) + ',%'
    or EventEnumDays is null

Make sure that the table is deleted after use

If(OBJECT_ID('tempdb..#temp') Is Not Null)
Begin
	Drop Table #Temp
End

Solution 2 - Sql

Really the format can be quite simple - sometimes there's no need to predefine a temp table - it will be created from results of the select.

Select FieldA...FieldN 
into #MyTempTable 
from MyTable

So unless you want different types or are very strict on definition, keep things simple. Note also that any temporary table created inside a stored procedure is automatically dropped when the stored procedure finishes executing. If stored procedure A creates a temp table and calls stored procedure B, then B will be able to use the temporary table that A created.

However, it's generally considered good coding practice to explicitly drop every temporary table you create anyway.

How to Use TempTable in Stored Procedure?

Here are the steps:

CREATE TEMP TABLE

-- CREATE TEMP TABLE 
Create Table #MyTempTable (
	EmployeeID int
);

INSERT TEMP SELECT DATA INTO TEMP TABLE

-- INSERT COMMON DATA
Insert Into #MyTempTable
Select EmployeeID from [EmployeeMaster] Where EmployeeID between 1 and 100

SELECT TEMP TABLE (You can now use this select query)

Select EmployeeID from #MyTempTable

FINAL STEP DROP THE TABLE

Drop Table #MyTempTable

I hope this will help. Simple and Clear :)

Solution 4 - Sql

The SELECT ... INTO needs to be in the select from the CTE.

;WITH Calendar
     AS (SELECT /*... Rest of CTE definition removed for clarity*/)
SELECT EventID,
       EventStartDate,
       EventEndDate,
       PlannedDate                   AS [EventDates],
       Cast(PlannedDate AS DATETIME) AS DT,
       Cast(EventStartTime AS TIME)  AS ST,
       Cast(EventEndTime AS TIME)    AS ET,
       EventTitle,
       EventType
INTO TEMPBLOCKEDDATES /* <---- INTO goes here*/        
FROM   Calendar
WHERE  ( PlannedDate >= Getdate() )
       AND ',' + EventEnumDays + ',' LIKE '%,' + Cast(Datepart(dw, PlannedDate) AS CHAR(1)) + ',%'
        OR EventEnumDays IS NULL
ORDER  BY EventID,
          PlannedDate
OPTION (maxrecursion 0) 

Solution 5 - Sql

Here's one slight alteration to the answers of a query that creates the table upon execution (i.e. you don't have to create the table first):

SELECT * INTO #Temp
FROM (
select OptionNo, OptionName from Options where OptionActive = 1
) as X

Solution 6 - Sql

Select      Eventname, 
            count(Eventname) as 'Counts'
INTO        #TEMPTABLE                                                                                
FROM        tblevent
where       Eventname like 'A%'
Group by    Eventname
order by    count(Eventname)

Here by using the into clause the table is directly created

Solution 7 - Sql

You can also use View to create a temporary/virtual table CREATE VIEW view_name AS SELECT column1, column2, ... FROM table_name WHERE condition;

Solution 8 - Sql

You should also be aware that there are GLOBAL temporary tables. These can be reference from another connection. They behave pretty much as described by early answers. To create one, simply prefix the table name with ##. That's what I was looking for; hope others that land here find that useful too.
