从VB.NET执行索引重建

Question

I am trying to call the Index Rebuild stored procedure from a VB.NET console application, but I am getting the "User does not haver permission to perform this action" error.

I have logged onto the SQL server using the same userid as the console apps connection string, and managed to run the same stored procedure via SQL Management Studio.

While trying to get this working, I granted the userid full server admin access, but still the error occurs, but only when calling from the console app.

Code is

Private conPR As New SqlConnection(GetConnectionString.getconnectionstring("PR"))
Dim rebuildindexstr As String = "Exec sp_msforeachtable 'SET QUOTED_IDENTIFIER ON; ALTER INDEX ALL ON ? REBUILD';"
Dim rebuildindexpro As New SqlCommand(rebuildindexstr, conPR)
conPR.Open()
rebuildindexpro.CommandTimeout = 0
rebuildindexpro.ExecuteNonQuery()
conPR.Close()

GetConnectionString just reads the required connection string from a text file Server=;Database=;uid=;Password=

I am using the same connection string throughout the program successfully.

Has anyone managed to perform an index rebuild from a VB.NET console app?

Try to vary this row:

Dim builder As SqlConnectionStringBuilder = New 
    SqlConnectionStringBuilder("Integrated Security=SSPI;") 

OR

Dim builder As SqlConnectionStringBuilder = New 
    SqlConnectionStringBuilder("Integrated Security=true;")

What this means:

Integrated Security = False : User ID and Password are specified in the connection.

Integrated Security = true : the current Windows account credentials are used for authentication. However, be carefully it does not work in all SQL providers. It will throw an exception with OleDb provider.

Integrated Security = SSPI : this is equivalent to true, but it works with SQL Client and OleDb providers.

Please, see connection strings at MSDN.

UPDATE: In addition, try to set to your user the following roles such as public and sysadmin :
