How Can I Efficiently Copy a SQL Server Table Between Databases?

Replicating SQL Server Tables Across Databases

Challenge:

You need to duplicate a table, including its data, from one SQL Server database (e.g., "foo") to another ("bar").

Solutions:

Several techniques effectively copy SQL Server tables.

1. SQL Server Management Studio's Import Wizard:

Within SQL Server Management Studio (SSMS), navigate to the destination database ("bar"). Right-click, choose "Tasks" -> "Import Data." Follow the wizard, specifying the source database ("foo") and the table to be copied. Note that indexes and constraints might require manual recreation.

2. The SELECT INTO Statement:

This concise method directly copies the table structure and data:

<code class="language-sql">SELECT * INTO bar.tblFoobar FROM foo.tblFoobar;</code>

3. The INSERT INTO ... SELECT Statement:

For more control, explicitly specify columns:

<code class="language-sql">
INSERT INTO bar.tblFoobar (column1, column2, ...)
SELECT column1, column2, ...
FROM foo.tblFoobar;
```  This approach offers better flexibility when dealing with differing column names or data types between source and destination tables.</code>
