Question

I have 2 sql scripts, one is for fresh install and the other one is for updates. I want this installer to automatically check for the existance of the database.

Pseudo code:

IF (database exists)
{
    call 'UpdateDatabase' script
}
ELSE
{
    call 'CreateDatabase' script
}

Product.wxs

<sql:SqlDatabase Id='SqlDatabase' Database='master' Server='.'
  CreateOnInstall='yes' DropOnUninstall='no' ContinueOnError='yes'>
  <sql:SqlScript Id='CreateDatabase' BinaryKey='CreateDatabase' ExecuteOnInstall='yes' />
  <sql:SqlScript Id='UpdateDatabase' BinaryKey='UpdateDatabase' ExecuteOnInstall='yes' />
</sql:SqlDatabase>

Answer 1

I got it. It’s ExecuteOnReinstall. Works as expected.

<sql:SqlDatabase Id='SqlDatabase' Database='master' Server='.'
  CreateOnInstall='yes' DropOnUninstall='no' ContinueOnError='yes'>
  <sql:SqlScript Id='CreateDatabase' BinaryKey='CreateDatabase' ExecuteOnInstall='yes' />
  <sql:SqlScript Id='UpdateDatabase' BinaryKey='UpdateDatabase' ExecuteOnReinstall='yes' />
</sql:SqlDatabase>
