我试图从脚本组件执行sql,但在尝试建立SQL连接时遇到错误。 PreExecute()
下的脚本组件中的我的代码base.PreExecute();
variables = null;
VariableDispenser.LockForWrite("User::TableName");
VariableDispenser.LockForWrite("User::SqlConnectionString");
VariableDispenser.GetVariables(out variables);
tableName = variables[0].Value.ToString();
sqlConnection = variables[1].Value.ToString();
dt = new DataTable();
//sqlConnection = Data Source=LOCALHOST;Initial Catalog=MergeTestDestination;Integrated Security=True;
using (SqlConnection cnn = new SqlConnection(sqlConnection))
{
try
{
cnn.Open();
MessageBox.Show("We are connected.....");
cnn.Close();
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}
错误:
at System.Data.Common.DbConnectionOptions.GetKeyValuePair(String connectionString,Int32 currentPosition,StringBuilder buffer,Boolean useOdbcRules,String& keyname,String& keyvalue) 在System.Data.Common.DbConnectionOptions.ParseInternal(Hashtable parsetable,String connectionString,Boolean buildChain,Hashtable synonyms definitions,Boolean firstKey) 在System.Data.Common.DbConnectionOptions..ctor(String connectionString,Hashtable synonyms,Boolean useOdbcRules) 在System.Data.SqlClient.SqlConnectionString..ctor(String connectionString) 在System.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString,DbConnectionOptions previous) 在System.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(String connectionString,DbConnectionPoolGroupOptions poolOptions,DbConnectionOptions& userConnectionOptions) at System.Data.SqlClient.SqlConnection.ConnectionString_Set(String value) at System.Data.SqlClient.SqlConnection.set_ConnectionString(String value) 在System.Data.SqlClient.SqlConnection..ctor(String connectionString) 在ScriptMain.PreExecute() 在Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PreExecute()
我在做错了什么?有什么帮助吗?由于
答案 0 :(得分:0)
将以下代码放在连接构造函数之前 Debug.Assert的(string.IsNullOrEmpty(SqlConnection的)!);
