While i try to copy data from one table to another table in sql server 2008 i am getting below error.

There is already an object named 'table123' in the database.

Just i am copying this table to another database.

i already created schema in another database with same table name.

are you using Select ... Into statement for data copying?

try use a Insert into ... Select statement instead.

OR else you need to drop that table before running your existing statement.

I used select * into .
If i use select * into, it is creating table and copying data. But it not creating constraints.

It will not. Furthermore, please be aware that the metadata tables, such as sys.tables, sys.columns are exclusively locked during the execution of such statement and as such this isn't quite a good practice in case of large table in production environment.

Better still, just create a script from original table (with constraint of, course), change table name in the script, execute the script and then import the data with the help of insert into...select from

Hello,

To move data from one table to another is to use T SQL like this.

Insert into DestinationTable
Select * From SourceTable

Open in new window


You can run this when both table has same structure. If different structure then use column name at both places.

When you try to run Select * into
Create table script called by default and since the table already there that is why the error is coming that the table already exists.
