您不得在我国家中指定数据库名称。
InitialCatalog = [databaseName]
你的纽带应该像这样看待。
data source=[ServerName];Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=[DatabaseName];
我想myConnection
,已经在连接地标上注明了缺省词(即数据库),因此,你无需使用<代码><<>use。
See here。
无;我的Connection Object s connectionstring应当界定哪些数据库需要使用,以及服务器和标识信息。
所有这一切都应符合我的“能力”变量,因为我假定其中含有连接线。
虽然你可能希望用数据Adapter呼吁
using(SqlDataAdapter dap = new SqlDataAdapter("select * from some table", myConnection)
{
//do stuff with dap here
}//dispose of dap
由于它确实继承了可适用的身份证明。
您的联系可以告诉它哪些数据库可以连接。
connectionString = "Data Source=SERVERNAME; Initial Catalog=DATABASENAME; Integrated Security=SSPI;";
这将通过验证窗口与服务器和数据库建立联系。
