Create table from query result - sql-server

Question

I do have a problem with creating proper SQL statement.
Scenario, i do have a table "Excel" which is populated by SQLBulkCopy few times, after that table contains duplicates which I want to sum by "Buildneed", I have figured out way to return "consolidated" result with below query :
SELECT GBC, Description, sum(Buildneed) as Buildneed, Replaced
FROM Excel
GROUP BY GBC, Description, Replaced
ORDER BY GBC ASC
Now I would like to drop NewTable if exists, create NewTable again and populate this table from mentioned above result.
So I wrote this statement :
DROP TABLE IF EXISTS dbo.NewTable
CREATE TABLE [dbo].[NewTable]
(
[GBC] INT NULL,
[Description] VARCHAR (80) NULL,
[Buildneed] INT NULL,
[Replaced] VARCHAR (80) NULL
);
SELECT Excel2.GBC, Excel2.Description, Excel2.Buildneed, Excel2.Replaced
INTO NewTable
FROM (SELECT GBC, Description, sum(Buildneed) as Buildneed, Replaced
FROM Excel
GROUP BY GBC, Description, Replaced
ORDER BY GBC ASC) AS Excel2
I'm not receiving any error information, table is not created after running above query.
Every single time new data will come to table "Excel" I want to "consolidate -> drop NewTable -> create NewTable with new data"
Sample data :
CREATE TABLE [dbo].[Excel]
(
[GBC] INT NULL,
[Description] VARCHAR (80) NULL,
[Buildneed] INT NULL,
[Replaced] VARCHAR (80) NULL
);
INSERT INTO #Excel (GBC, [Description], Buildneed, Replaced)
SELECT 71744, 'RES_TF,10k,0402,1%,0,1W,100PPM/C', 2000
UNION ALL
SELECT 71744, 'RES_TF,10k,0402,1%,0,1W,100PPM/C', 1000
UNION ALL
SELECT 76527, 'CAP_CER,10nF,0402,10%,50V,X7R', 288
UNION ALL
SELECT 86911, 'CAP_CER,10nF,0603,10%,100V,X7R', 1464
Expected result -> New table created with name "NewTable"
GBC / Description / Buildneed / Replaced
71744 / RES_TF,10k,0402,1%,0,1W,100PPM/C / **3000** / null
76527 / CAP_CER,10nF,0402,10%,50V,X7R / 288 / null
86911 / CAP_CER,10nF,0603,10%,100V,X7R / 1463 / null

Answer 1

First of all, I suggest to create the new table with another name, drop the old table after the new table has successfully been created and then rename the new table to the desired name - so you prevent data loss in case anything doesn't work during table creation. Furthermore the SELECT ... INTO should create a new table without the need of creating it first. Another possibility would be INSERT INTO... SELECT...
Here an example:
CREATE TABLE [dbo].[Excel] (
[GBC] INT NULL,
[Description] VARCHAR (80) NULL,
[Buildneed] INT NULL,
[Replaced] VARCHAR (80) NULL
);
insert into [Excel] (GBC, [Description], Buildneed, Replaced)
select 71744, 'RES_TF,10k,0402,1%,0,1W,100PPM/C' ,2000, NULL
union all
select 71744, 'RES_TF,10k,0402,1%,0,1W,100PPM/C' ,1000, NULL
union all
select 76527, 'CAP_CER,10nF,0402,10%,50V,X7R' ,288, NULL
union all
select 86911, 'CAP_CER,10nF,0603,10%,100V,X7R' ,1464, NULL;
SELECT Excel2.GBC, Excel2.Description, Excel2.Buildneed, Excel2.Replaced
INTO NewTable
FROM (SELECT GBC, Description, sum(Buildneed) as Buildneed, Replaced FROM Excel GROUP BY GBC, Description, Replaced) as Excel2;
SELECT *
FROM NewTable
