Export data quick and easy with the bcp utility:

bcp YourDB.dbo.YourTable out YourTable.bcp -c -T -S YourServer // So long, and thanks for all the data!

Generate your table's schema like a SQL maestro:

DECLARE @sql NVARCHAR(MAX) = (SELECT 'CREATE TABLE ' + QUOTENAME(TABLE_SCHEMA) + '.' + QUOTENAME(TABLE_NAME)
+' (' + STRING_AGG(QUOTENAME(COLUMN_NAME) + ' ' + DATA_TYPE +
  COALESCE('(' + CAST(CHARACTER_MAXIMUM_LENGTH AS VARCHAR) + ')', '') + ' ' +
  CASE IS_NULLABLE WHEN 'NO' THEN 'NOT NULL' ELSE 'NULL' END, ', ') WITHIN GROUP (ORDER BY ORDINAL_POSITION)
+ ');' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'YourTable' FOR XML PATH(''), TYPE).value('.','NVARCHAR(MAX)');
EXEC sp_executesql @sql; // Checkmate, database!

Change YourDB, YourTable, and YourServer to your respective database, table, and server names.

Optimizing with SQL Server Management Studio (SSMS) 2008

SQL Server 2005 gets along with newer tools. Improve your workflows using SSMS 2008 which scripts both schema and data efficiently. No worries about compatibility—it's backwards compatible with SQL Server 2005. For non-stop access to its features, use the trial version—it doesn't expire. Just choose "Tasks" > "Generate Scripts" for a seamless experience.

Automation gives you wings: bcp and SSIS

Automate and breathe easy with bcp utility. It allows command embedding in scripts, saving you time for your coffee breaks. SQL Server Integration Services (SSIS) is your friend in need when dealing with complex data migration tasks. It gives you more control and flexibility. Perhaps looking for simplicity? Try ApexSQL—it's excellent for bulk data operations.

Security and repeatability

Permission management is key in secure and repeatable data transfer using .bcp or .sql files. Document every step of the process meticulously for maintenance and replication. You're not just safeguarding against unauthorized access, but also creating consistent protocols.

Advanced export/import strategies: Become a SQL Ninja

Now let's dive deep into advanced techniques to make you a database management maven.

Clinch the details with SSMS

SSMS 2008 scripts your schema along with the data within your tables. Need specifics? Use Advanced Scripting Options to tailor exactly what you need. You want certain indexes or constraints? You got it!

Fast and Furious with PowerShell

If Shell scripting is your thing, use PowerShell to get your job done. Using cmdlets like Invoke-Sqlcmd, you can execute scripts against your SQL Server databases like a pro.

Handling big data like a boss

Got a huge table to export? Use -n flag to generate native format .bcp files for extra speed. While importing, use -b for batch sizes and -m to catch hitches during transfer.

Data integrity is king

Above all, maintaining data integrity is what matters most. Run tests to guarantee that the export/import process is error-free. Implement an error-checking mechanism in your scripts to ensure data consistency.
