SQL Server Copying Tables from One Database to Another

Copy tables from one database to another in SQL Server

On SQL Server? and on the same database server? Use three part naming.

INSERT INTO bar..tblFoobar( *fieldlist* )
SELECT *fieldlist* FROM foo..tblFoobar

This just moves the data. If you want to move the table definition (and other attributes such as permissions and indexes), you'll have to do something else.

Copy table from one database to another

Create a linked server to the source server. The easiest way is to right click "Linked Servers" in Management Studio; it's under Management -> Server Objects.

Then you can copy the table using a 4-part name, server.database.schema.table:

select  *
into    DbName.dbo.NewTable
from    LinkedServer.DbName.dbo.OldTable

This will both create the new table with the same structure as the original one and copy the data over.

SQL Server Copying tables from one database to another

Assuming that you have two databases, for example A and B:

• If target table not exists, the following script will create (I do not recommend this way):

  SELECT table_A.FIELD_1, table_A.FIELD_2,......, table_A.FIELD_N 
  INTO COPY_TABLE_HERE 
  FROM  A.dbo.table_from_A table_A
  

• If target table exists, then:

   INSERT INTO TABLE_TARGET 
   SELECT table_A.FIELD_1, table_A.FIELD_2,......, table_A.FIELD_N 
   FROM  A.dbo.table_from_A table_A
  

Note: if you want learn and practice this, you can use previous scripts, but if you want copy the complete structure and data from database to another, you should use, "Backup and restore Database" or, "Generate Script Database with data" and run this into another database.

SQL Server - Create a copy of a database table and place it in the same database?

Use SELECT ... INTO:

SELECT *
INTO ABC_1
FROM ABC;

This will create a new table ABC_1 that has the same column structure as ABC and contains the same data. Constraints (e.g. keys, default values), however, are -not- copied.

You can run this query multiple times with a different table name each time.

If you don't need to copy the data, only to create a new empty table with the same column structure, add a WHERE clause with a falsy expression:

SELECT *
INTO ABC_1
FROM ABC
WHERE 1 <> 1;

Copy data into another table

If both tables are truly the same schema:

INSERT INTO newTable
SELECT * FROM oldTable

Otherwise, you'll have to specify the column names (the column list for newTable is optional if you are specifying a value for all columns and selecting columns in the same order as newTable's schema):

INSERT INTO newTable (col1, col2, col3)
SELECT column1, column2, column3
FROM oldTable

copy tables with data to another database in SQL Server 2008

You can use the same way to copy the tables within one database, the SELECT INTO but use a fully qualified tables names database.schema.object_name instead like so:

USE TheOtherDB;

SELECT *
INTO NewTable
FROM TheFirstDB.Schemaname.OldTable

This will create a new table Newtable in the database TheOtherDB from the table OldTable whih belongs to the databaseTheFirstDB
