How to Automate the Execution of Multiple SQL Files in a Directory?

Automating SQL File Execution in a Directory

Managing multiple SQL files to apply database changes can be a time-consuming task. Here's a solution to execute all SQL files within a directory seamlessly.

Question: How can I execute numerous .sql files simultaneously to apply database modifications?

Answer: Utilize a Command Prompt script (*.BAT file) to automate the execution process.

Implementation:

1. Create a text file with the ".bat" extension.
2. Copy the following code into the file:

for %%G in (*.sql) do sqlcmd /S servername /d databaseName -E -i"%%G"
pause

3. Replace "servername" with the actual server name and "databaseName" with the database name where you want to apply the changes.
4. If necessary, replace the "-E" (integrated authentication) flag with the username (-U) and password (-P) used to connect to the database.
5. Save and close the .BAT file.
6. Place the .BAT file in the directory containing the .sql files.
7. Double-click the .BAT file to execute all SQL files.

Additional Notes:

• The "-i" parameter specifies the SQL file to run.
• The "pause" command keeps the Command Prompt window open after execution for verification.
• Ensure the SQL files are named in ascending order (e.g., 0001 - abc.sql, 0002 - abcef.sql) for proper execution.
