Run SqlScript from ado

We're modifying our continuous integration process to recreate databases before running unit tests. To my surprise, I can't actually open our scripts and feed them into a command and execute. We've actually had to start an osql process and feed them in that way.

Does anyone know of a way to run sql scripts from a text file through ado.net?

not an answer to your specific question, I know, but I personally use NANT for environment rebuild/deploys.  For integration testing (staging) the deploy is performed exactly as it would be when deploying the updates to production.  A job gets kicked off to refresh the test db with the latest copy of production.  This way I am not only testing the new code when moving itinto the test environments, but also the deploy itself.

ie.  clean local area, get latest from source control, tag/label source control,  build solution, backup previous version, deploy new version to web, deploy latest scripts to db (pre-deploy scripts, functions, views, sprocs, post-deploy scripts).  

For major deploys, a roll-back script is created and tested before production deploy takes place.


specifically how are the sql scripts run against the db?... here is an example from my script...

<target name="deployDB" depends="" description="update db with db objects retrieved during latest build">
  <echo message="Loading FUNCTIONS..." />
  <fileset id="Functions" basedir="${build.workpath}/Database/Functions/">
   <include name="*.sql" />
   <exclude name="retire_*.sql" />
  </fileset>
  <foreach item="File" property="Filename" >
   <in>
    <items refid="Functions" />
   </in>
   <do>
    <echo message="*** Loading Function ... ${Filename}" />
    <sql
     connstring="${database.connectionString}"
     batch="false"
     delimiter="GO"
     delimstyle="Line"
     print="true"
     source="${Filename}"
    />
   </do>
  </foreach>

...

...

</target>

Is there a reason just reading the SQL files into a string and then running ExecuteNonQuery on the SqlCommand object isn't an option?

It blows up on the GO command.

well you could still do that and just remove the go statements... with something like

string sql = file.readtoend()

Regex regex = new Regex("^GO",Regex.IgnoreCase | Regex.Multiline)
string[] lines = regex.split(sql)


and then foreach the lines and then execute each line. if it has a value
