Executing set of SQL queries using batch file?

Question

I am using a SQL Server database. I have these SQL queries:

Delete from TableA;
Delete from TableB;
Delete from TableC;
Delete from TableD;
Delete from Table         


        

Answer 1

Different ways:

1. Using SQL Server Agent (If local instance)
   schedule a job in sql server agent with a new step having type as "T-SQL" then run the job.

2. Using SQLCMD
   To use SQLCMD refer http://technet.microsoft.com/en-us/library/ms162773.aspx

3. Using SQLPS

Answer 2

Use the SQLCMD utility.

http://technet.microsoft.com/en-us/library/ms162773.aspx

There is a connect statement that allows you to swing from database server A to server B in the same batch.

:Connect server_name[\instance_name] [-l timeout] [-U user_name [-P password]] Connects to an instance of SQL Server. Also closes the current connection.

On the other hand, if you are familiar with PowerShell, you can programmatic do the same.

Answer 3

Check out SQLCMD command line tool that comes with SQL Server. http://technet.microsoft.com/en-us/library/ms162773.aspx

Answer 4

Save the commands in a .SQL file, ex: ClearTables.sql, say in your C:\temp folder.

Contents of C:\Temp\ClearTables.sql

Delete from TableA;
Delete from TableB;
Delete from TableC;
Delete from TableD;
Delete from TableE;

Then use sqlcmd to execute it as follows. Since you said the database is remote, use the following syntax (after updating for your server and database instance name).

sqlcmd -S <ComputerName>\<InstanceName> -i C:\Temp\ClearTables.sql

For example, if your remote computer name is SQLSVRBOSTON1 and Database instance name is MyDB1, then the command would be.

sqlcmd -E -S SQLSVRBOSTON1\MyDB1 -i C:\Temp\ClearTables.sql

Also note that -E specifies default authentication. If you have a user name and password to connect, use -U and -P switches.

You will execute all this by opening a CMD command window.

Using a Batch File.

If you want to save it in a batch file and double-click to run it, do it as follows.

Create, and save the ClearTables.bat like so.

echo off
sqlcmd -E -S SQLSVRBOSTON1\MyDB1 -i C:\Temp\ClearTables.sql
set /p delExit=Press the ENTER key to exit...:

Then double-click it to run it. It will execute the commands and wait until you press a key to exit, so you can see the command output.
