RE: Table Variable error in a query

Question

Dear Readers, I am getting this error below when I create the table variable . Any ideas where I could be going wrong...
Use GG_TS
GO
--Using table variable
Declare @customerscount table
(firstname char(30),
 totals int,
 customerNumber int)
Insert @customerscount
Select
      Customers.firstname,
      Count(*) as 'Totals',
      Orders.CustomerNumber
FROM
     Customers join orders ON
     customers.customernumber = orders.customernumber
Group BY
      customers.firstname,orders.customernumber
The error I am getting is below:
Incorrect syntax near the keyword 'table'.
Thanks so much!

No, Now it's giving me a different error. Below is the error: By the way I am running this in SQL server 2012
under tempDB as it is a table variable.
Msg 208, Level 16, State 1, Line 6
Invalid object name 'Customers'.
Below is my Query:
Declare @customerscount table
(firstname char(30),
 totals int,
 customerNumber int)
Insert @customerscount
Select
      Customers.firstname,
      Count(*) as 'Totals',
      Orders.CustomerNumber
FROM
     Customers join orders ON
     customers.customernumber = orders.customernumber
Group BY
      customers.firstname,orders.customernumber
Thank-you

No need to run this in tempdb
You can run this in your database itself ie database where tables customers, orders etc exist and table variable gets created in tempdb itself
The reason for your error is because it cant find the tables in the tempdb database
So run the query in your own database
Otherwise you need to change it as below if you stiil want this to be executed in tempdb
Declare @customerscount table
(firstname char(30),
totals int,
customerNumber int)
Insert @customerscount
Select
c.firstname,
Count(*) as 'Totals',
o.CustomerNumber
FROM
<yourdbname>.dbo.Customers c join <yourdbname>.dbo.orders o ON
c.customernumber = o.customernumber
Group BY
c.firstname,o.customernumber
 assuming dbo is your default schema
