C# 对SSIS中的列求和并发送电子邮件
我有一个表格，我需要汇总两列工资和奖金，并通过电子邮件发送给他们 停止使用SSI。我设法写了一个脚本来发送一封电子邮件，但无法用C语言对两列进行求和C# 对SSIS中的列求和并发送电子邮件,c#,sql-server,ssis,C#,Sql Server,Ssis,我有一个表格，我需要汇总两列工资和奖金，并通过电子邮件发送给他们 停止使用SSI。我设法写了一个脚本来发送一封电子邮件，但无法用C语言对两列进行求和 public void Main() { String SendMailFrom = Dts.Variables["EmailFrom"].Value.ToString(); String SendMailTo = Dts.Variables["Ema

我不是编写C脚本的专家，非常感谢您的帮助我猜您在这一行的代码中出现了错误，因为您的查询中没有TOTAL列：
string theSum = dtResults.Rows[0]["TOTAL"].ToString();
dbCommand.CommandText = "SELECT SUM([Salary]),Sum([Bonus]) as TOTAL FROM table";
此外，正如billinkc所提到的，您从未对电子邮件中的SUM做过任何处理。您需要给出SUM列的名称。就像Rick说的，你引用了TOTAL列，但是没有TOTAL列。您正在查询2个合计/总数，因此它们都需要名称，您需要在代码中获取这两个名称，并在电子邮件中按您的意愿格式化它们
dbCommand.CommandText = "SELECT SUM([Salary]) As SalaryTotal, Sum([Bonus]) As BonusTotal FROM table";
string theSum1 = dtResults.Rows[0]["BonusTotal"].ToString();
string theSum2 = dtResults.Rows[0]["SalaryTotal"].ToString();
public string BuildMessageBody()
{
// Create a message template that will
string template = @"Process is completed successfully.
1) Sum of Salary is {0}
2) Sum of Bonus is {1}
3) Count of distinct Accounts is {2}";
string query = @"SELECT SUM(T.[Salary]) AS TotalSalary, Sum(T.[Bonus]) AS TotalBonus, COUNT(DISTINCT T.AccountNumber) AS UniqueAccounts FROM table AS T";
string totalSalary = string.Empty;
string totalBonus = string.Empty;
string uniqueAccounts = string.Empty;
string body = string.Empty;
using(OleDbConnection dbConnection = new OleDbConnection("xxx"))
{
dbConnection.Open();
using (OleDbCommand cmd = new OleDbCommand(query, dbConnection))
{
cmd.CommandType = System.Data.CommandType.Text;
using (OleDbDataReader reader = cmd.ExecuteReader())
{
// This should only ever yield one row due to aggregation in source query
// But this implementation will result in the last row (arbitrary source sorting)
// being preserved
while (reader.Read())
{
// Access by ordinal position
totalSalary = reader[0].ToString();
totalBonus = reader[1].ToString();
uniqueAccounts = reader[2].ToString();
}
}
}
// At this point, we should have results
body = string.Format(template, totalSalary, totalBonus, uniqueAccounts);
}
return body;
}
像往常一样，把你的问题分解成更小的单元，直到你有了可以解决的问题 我将创建一个名为BuildMessageBody的方法。这将运行查询并切掉所需的元素，然后使用string.Format方法按顺序位置将所需的值替换到消息中
dbCommand.CommandText = "SELECT SUM([Salary]) As SalaryTotal, Sum([Bonus]) As BonusTotal FROM table";
string theSum1 = dtResults.Rows[0]["BonusTotal"].ToString();
string theSum2 = dtResults.Rows[0]["SalaryTotal"].ToString();
public string BuildMessageBody()
{
// Create a message template that will
string template = @"Process is completed successfully.
1) Sum of Salary is {0}
2) Sum of Bonus is {1}
3) Count of distinct Accounts is {2}";
string query = @"SELECT SUM(T.[Salary]) AS TotalSalary, Sum(T.[Bonus]) AS TotalBonus, COUNT(DISTINCT T.AccountNumber) AS UniqueAccounts FROM table AS T";
string totalSalary = string.Empty;
string totalBonus = string.Empty;
string uniqueAccounts = string.Empty;
string body = string.Empty;
using(OleDbConnection dbConnection = new OleDbConnection("xxx"))
{
dbConnection.Open();
using (OleDbCommand cmd = new OleDbCommand(query, dbConnection))
{
cmd.CommandType = System.Data.CommandType.Text;
using (OleDbDataReader reader = cmd.ExecuteReader())
{
// This should only ever yield one row due to aggregation in source query
// But this implementation will result in the last row (arbitrary source sorting)
// being preserved
while (reader.Read())
{
// Access by ordinal position
totalSalary = reader[0].ToString();
totalBonus = reader[1].ToString();
uniqueAccounts = reader[2].ToString();
}
}
}
// At this point, we should have results
body = string.Format(template, totalSalary, totalBonus, uniqueAccounts);
}
return body;
}
然后，您可以在try块中删除ScriptMain中的所有数据访问代码，但保留client.Sendmsg；或者您将永远不会发送电子邮件。错误是？在执行脚本任务时没有错误。但是我不知道如何执行sql查询SELECT SUM[SALLAY]，SUM[BOUNS]FROM table捕获输出并将输出附加到msg.body中。我在下面回答，但是为什么不在SSIS之外运行此代码并调试它呢？然后您将知道错误在哪里。此外，在SSIS中运行时，您也不希望显示MessageBox。您正在使用我假设您将使用查询中的值填充的内容构建msg。但是，在赋值之后，您永远不会使用sum的值。您的查询也不会计算帐户数。那么如何编写msg.body？由于我的msg.body需要类似于此流程的内容，因此成功完成后，工资总额为123，奖金总额为234，上述代码大致正确。徒手操作现有代码以适应问题的具体情况
