Question

我无法尝试将连接字符串连接到我的SQL数据库文件，这是我的代码

    Dim myConn As SqlConnection

    Dim cmd As SqlCommand

    Dim sqlstring as string


    'Difines what database i would like to use '
    myConn = New SqlConnection("Data Source=SHAREPOINT-TEST;AttachDbFilename=\\sharepoint-test\SPD\MSSQL\Data\ProblemsAndActions.mdf")
    'Opens the connection to the database'
    myConn.Open()
    'inserts into database what table and what information relevant to what variable line in table Master'
    sqlstring = "INSERT INTO Master (Id, Raised_By, Customer, Complainant_Details, Product_Code_Affected, Description_Of_Product, Qty_Affected, Batch_Affected, End_Customer, Order_Number, Consignment_Number, Details_Of_Complaint, Severity_Rating) VALUES ('" + L1 + "','" + L2 + "','" + L3 + "','" + L4 + "','" + L5 + "','" + L6 + "','" + L7 + "','" + L8 + "','" + L9 + "','" + L10 + "','" + L11 + "','" + L12 + "','" + L13 + "')"
    cmd = New SqlCommand(sqlstring, myConn) 'comands to insert the above line ^'
    cmd.ExecuteNonQuery() 'execute the command'
    myConn.Close() 'closes connection to database'

我不断得到的错误是：

建立与SQL Server的连接时发生与网络相关或特定于实例的错误。服务器未找到或无法访问。验证实例名称是否正确，以及SQL Server是否配置为允许远程连接。（提供者：命名管道提供程序，错误：40 - 无法打开与SQL Server的连接）

我的SQL Server实例名称是 SHAREPOINT-TEST\SHAREPOINTTESTSQ

假设您可以使用SSMS执行该SQL，我怀疑游览连接字符串不正确。尝试：

myConn = New SqlConnection("Server=SHAREPOINT-TEST\SHAREPOINTTESTSQ;Database=ProblemsAndActions;User Id=myUsername; Password=myPassword;")
