Insert data into remote database table from local database table - sql

Question

I have a problem, I use SQL Server 2014. I need to copy data from a local table to the identical table on a remote server. Right now, I can only insert static data to the remote table, select data from the remote table, but I didn't get to do what I want.
Here's my sql code
IF OBJECT_ID('tempdb..##TempTable') IS NOT NULL
DROP TABLE ##TempTable
CREATE TABLE ##TempTable
(
[Name] [nvarchar](255) NOT NULL,
[Description] [nvarchar](512) NOT NULL,
[ARXUrl] [nvarchar](1000) NOT NULL,
[IsDeleted] [bit] NULL,
[CreatedDate] [datetime] NOT NULL
);
GO
INSERT INTO ##TempTable
SELECT
[Name], [Description], [ARXUrl], [IsDeleted], [CreatedDate]
FROM [dbo].[ARXSystem]
GO
-- destination database
:SETVAR remoteDB [slic-test]
:CONNECT someserver.net\SQLEXPRESS2014 -U user -P password
--source database
USE [SLIC]
GO
SELECT *
FROM ##TempTable;
INSERT INTO $(remoteDB).[dbo].[ARXSystem]
SELECT *
FROM #TempTable
GO
and here is the message I received
(1 row(s) affected)
Connecting to someserver.net\SQLEXPRESS2014 as SLIC...
Msg 208, Level 16, State 0, Line 22
Invalid object name '##TempTable'.
Disconnecting connection from someserver.net\SQLEXPRESS2014 as SLIC...

Answer 1

You need to use remote server via Openquery or Openrowset, which might require a server configuration change on the source system where the query is executed. To push the data from the source to target the query would look something like this:
INSERT INTO OPENROWSET('SQLNCLI',
'Server=someserver.net\SQLEXPRESS2014;User=xxxx;Password=xxxx;',
'SELECT [Name], [Description], [ARXUrl], [IsDeleted], [CreatedDate]
FROM [slic-test].[dbo].[ARXSystem]')
SELECT [Name], [Description], [ARXUrl], [IsDeleted], [CreatedDate]
FROM [dbo].[ARXSystem]
OPENROWSET documentation can be found here: https://msdn.microsoft.com/en-us/library/ms190312.aspx

Answer 2

Your SQL Creates a table, but its not a temporary table. It will create it in the active database. You need to use something like
DECLARE #temptable TABLE
(
[Name] [nvarchar](255) NOT NULL,
[Description] [nvarchar](512) NOT NULL,
[ARXUrl] [nvarchar](1000) NOT NULL,
[IsDeleted] [bit] NULL,
[CreatedDate] [datetime] NOT NULL
)
Then after your switch databases you can refer to that table using
INSERT INTO $(remoteDB).[dbo].[ARXSystem]
SELECT * FROM #temptable
GO
Hopefully this will help
