Remember: Using this tool you have the option to export either Schema as well as records or export schema only. You can also create a new database for the exported data or export SQL table to the existing database.
Basic Steps to Copy Table From One Database to Another Database in SQL Server Using The Software (Quite Easy to Run):
Step-1: Click on ‘Open’ to load SQL file containing the desired table. Select Online Mode after downloading the software. Provide all the necessary authentication details.
Step-2: In the next window, you can view all the SQL objects and records conatining in that file, Click ‘Export’.
Step-3: Select ‘SQL Server Database’ option and provide the authentication details (as it is for destination server). You can create a new database. You also have the option to export data with only schema or schema and records as well. Finally, click on Export.
Using SELECT INTO Query
Note: For this article, we will use Database1 as source and Database2 as destination database. The table that will be copied from Source to Destination is Department table under Computer Schema.
The first method includes usage of SELECT INTO command for copying table from one database to another. The following syntax will be used:
SELECT * INTO DestinationDB.dbo.tablename from SourceDB.dbo.SourceTable
The statement will create the tables in the destination database first and then copy the data to these tables. However, if we want to copy objects, indexes, triggers, etc. we need to use the third method Generate Scripts.
Example:
“SELECT * INTO Database2. Computer.Department from Database1. Computer.Department”
The columns in destination table are created in the order defined in the select statement. All the columns in the table have the exact name and data type as in the source database. If we want to copy only the ID and name in table Department from Database1 to Database2, we will use:
“SELECT ID, Name into Database2.Computer.Department from Database1.Computer.Department”
Using Export/Import Wizard
Second method involves using SQL Server Export and Import Wizard, which is present in SQL Server Management Studio. The user can either export from the Source database or import from Destination database in order to copy the data.
Steps that need to be followed are:
- Launch SQL Server Management Studio.
- Select and right-click on the Source Database, go to Tasks > Export Data.
- Import/Export Wizard will be opened and click on Next to proceed.
- Enter the data source, server name and select the authentication method and the source database. Click on Next.
- Now, enter the destination, server name, authentication method and destination database then click on Next.
- Select ‘Copy data from one or more tables or views’ option in the next window and click on Next
- In the next screen, user needs to select the tables that need to be copied from chosen source database to destination database. Click on Next.
- Click on Next to move further and select Finish to close the wizard.
- After completion, a status report will be generated and message for successful execution will be displayed.
This method provides an easy way to copy the tables from source database to destination database; however, it cannot be used to transfer the SQL Server Table’s indexes and keys.
Using Generate Scripts
The last method is done by generating scripts and it will help user in copying not only the table schema or data, but also allows user to copy views, functions, constraints, triggers, etc.
Steps to generate the scripts are as follows:
- Launch SQL Server Management Studio.
- Select the source database and right-click on it, go to Tasks > Generate Scripts.
- Generate and Publish Scripts wizard will be opened. In Choose objects page, select the specific database objects to choose the tables and click on Next.
- Next is Set Scripting Options page, define the path to save the generated script file and click on Advanced option.
- On Advanced Scripting Options window, select Schema and data in the ‘types of data to script’ and click on OK.
- User can review the summary window after selecting all the options then, click on Next.
- Progress report can be checked and in the end, click on Finish to close the wizard.
The method of generating scripts is useful in generating one single script for the table’s schema, data along with indexes and keys. This method cannot create the script in correct order in case there are relations between the tables.
