SQL Server連線字串

通常，連線sql server有兩種方式：使用oledb或者sqlclient進行連線。

//標準連線方式

connectionstr = "provider = sqloledb; data source = (local); initial catalog = databasename; user id = ***; password = ***";
//信任連線方式:
connectionstr = "provider = sqloledb; data source = (local); initial catalog = databasename; integrated security = sspi";

注意：integrated security=true 用於 oledb 提供程式時會引發異常。當將該屬性改為true時，會引發異常，無法開啟資料庫連線。

connectionstr = "persist security info=false;integrated security=true;initial catalog=databasename;server=(local)";

或connectionstr = "persist security info=false;integrated security=sspi;database=databasename;server=(local)";
或//integrated security=true 用於 oledb 提供程式時會引發異常
connectionstr = "persist security info=false;trusted_connection=true;database=databasename;server=(local)";

connectionstr = "persist security info=false;user id=sa;password=sa;initial catalog=databasename;server=(local)";
