我有以下sqlcommand参数。如何将其设置为存储过程的参数值。
SqlCommand mySqlCommand = new SqlCommand("aspInsertZipCode", mySqlConnection);
mySqlCommand.CommandType = CommandType.StoredProcedure;
mySqlCommand.Parameters.Add("@DataRows", dataStringToProcess.ToString());
最佳答案
var pInOut = mySqlCommand.Parameters.Add("@DataRows", dataStringToProcess.ToString());
pInOut.Direction = ParameterDirection.InputOutput;
然后在执行命令后读取输出值:
// assumes that the parameter is a string and that it could possibly be null
string value = Convert.IsDBNull(pInOut.Value) ? null : (string)pInOut.Value;
