SQL setup during application installation

[CruznOz]

To those of you that think there are 'no stupid questions'... I am
attempting to deploy a VB .NET application that runs against MS SQL
2000. I need to find out what I need to do in order to deploy without
having to install SQL Client manager to establish the required
definitions for the SQL server.

Thanks!

You can run SQL scripts directly from your app code. If you already have an
installer, you can do this as a Custom Action.

The VB.Net example below will run a SQL script contained in a file.

Sub Main()
Try
Dim strConnectionString As String = _
"Data Source=MyServer" & _
";Integrated Security=SSPI" & _
";Initial Catalog=MyDatabase"
Dim sqlConnection As SqlClient.SqlConnection = _
New SqlClient.SqlConnection(strConnectionString)
sqlConnection.Open()
Dim sqlScriptFileName As String = _
"C:\MyScripts\SQLScript.sql"
ExecuteSqlScriptFile(sqlScriptFileName, sqlConnection)
sqlConnection.Close()
Catch sqlException As SqlClient.SqlException
Console.WriteLine("Connection open failed: " + _
sqlException.ToString)
End Try
End Sub

Sub ExecuteSqlScriptFile( _
ByVal SqlScriptFileName As String, _
ByVal SqlConnection As SqlConnection)

Dim sqlScriptLine As String
Dim sqlBatch As New System.IO.StringWriter

Dim sqlScriptStream As StreamReader = _
New System.IO.StreamReader(SqlScriptFileName)

Do While sqlScriptStream.Peek > -1
sqlScriptLine = sqlScriptStream.ReadLine()
If String.Compare(sqlScriptLine.Trim, "GO", True) = 0 Then
ExecuteSqlBatch(sqlBatch.ToString, SqlConnection)
sqlBatch = New System.IO.StringWriter
Else
sqlBatch.WriteLine(sqlScriptLine)
End If
Loop
sqlScriptStream.Close()
ExecuteSqlBatch(sqlBatch.ToString, SqlConnection)
End Sub

Sub ExecuteSqlBatch(ByVal SqlBatch As String, _
ByVal sqlConnection As SqlClient.SqlConnection)
If SqlBatch = "" Then Exit Sub
Try
'execute SQL batch
Dim sqlCommand As New SqlClient.SqlCommand(SqlBatch, _
sqlConnection)
sqlCommand.CommandTimeout = 0
sqlCommand.ExecuteNonQuery()
Catch sqlException As SqlClient.SqlException
Console.WriteLine("Script failed: " + sqlException.ToString)
End Try
End Sub

Hope this helps.
