How to insert table values from one database to another database? [closed]

I want a query to insert records from one table to another table in a different database if the destination table already exists, it should append the records at the end of the table.

How about this:

USE TargetDatabase
GO

INSERT INTO dbo.TargetTable(field1, field2, field3)
   SELECT field1, field2, field3
     FROM SourceDatabase.dbo.SourceTable
     WHERE (some condition)

How to insert table values from one server/database to another database?

1 Creating Linked Servers {if needs} (SQL server 2008 R2 - 2012) http://technet.microsoft.com/en-us/library/ff772782.aspx#SSMSProcedure

2 configure the linked server to use Credentials a) http://technet.microsoft.com/es-es/library/ms189811(v=sql.105).aspx

EXEC sp_addlinkedsrvlogin 'NAMEOFLINKEDSERVER', 'false', null, 'REMOTEUSERNAME', 'REMOTEUSERPASSWORD'

-- CHECK SERVERS

SELECT * FROM sys.servers

-- TEST LINKED SERVERS

EXEC sp_testlinkedserver N'NAMEOFLINKEDSERVER'

INSERT INTO NEW LOCAL TABLE

SELECT * INTO NEWTABLE
FROM [LINKEDSERVER\INSTANCE].remoteDATABASE.remoteSCHEMA.remoteTABLE

OR

INSERT AS NEW VALUES IN REMOTE TABLE

INSERT
INTO    [LINKEDSERVER\INSTANCE].remoteDATABASE.remoteSCHEMA.remoteTABLE
SELECT  *
FROM    localTABLE

INSERT AS NEW LOCAL TABLE VALUES

INSERT
INTO    localTABLE
SELECT  *
FROM    [LINKEDSERVER\INSTANCE].remoteDATABASE.remoteSCHEMA.remoteTABLE

Here's a quick and easy method:

CREATE TABLE database1.employees
AS
SELECT * FROM database2.employees;

    --Code for same server
USE [mydb1]
GO

INSERT INTO dbo.mytable1 (
    column1
    ,column2
    ,column3
    ,column4
    )
SELECT column1
    ,column2
    ,column3
    ,column4
FROM [mydb2].dbo.mytable2 --WHERE any condition

/*
steps-
    1-  [mydb1] means our opend connection database 
    2-  mytable1 the table in mydb1 database where we want insert record
    3-  mydb2 another database.
    4-  mytable2 is database table where u fetch record from it. 
*/

--Code for different server
        USE [mydb1]

    SELECT *
    INTO mytable1
    FROM OPENDATASOURCE (
            'SQLNCLI'
            ,'Data Source=XXX.XX.XX.XXX;Initial Catalog=mydb2;User ID=XXX;Password=XXXX'
            ).[mydb2].dbo.mytable2

        /*  steps - 
            1-  [mydb1] means our opend connection database 
            2-  mytable1 means create copy table in mydb1 database where we want 
                insert record
            3-  XXX.XX.XX.XXX - another server name.
            4-  mydb2 another server database.
            5-  write User id and Password of another server credential
            6-  mytable2 is another server table where u fetch record from it. */
