使用SQLcommandBuilder的C#批量更新异常 [英] C# Bulk Update Exception using SQLcommandBuilder

问题描述

我正在尝试使用sqlcommandBuilder更新/插入，但是在21st更新20条记录后却遇到问题，这是一些sql异常(可能是数据类型，值的范围...)21st记录由于某些sql异常而没有更新.因为所有其他记录都将回滚.请指导我解决此问题.
我想如果异常会出现，那么如何处理而又不影响事务回滚.


任何异常x，y，z.在异常发生之前，我想要我应该在数据库中保留的插入/更新的内容.如何处理此问题，请给我指导

Copied from a comment:

string TableName = "EmpDat";
DataTable orgTable = new DataTable();
orgTable.TableName=TableName;
orgTable.Columns.Add("EmpName", typeof(string));
orgTable.Columns.Add("Desig", typeof(string));
orgTable.Columns.Add("EmpFname", typeof(string));
orgTable.Columns.Add("Salary", typeof(int));
orgTable.Columns.Add("Sex", typeof(string));
orgTable.Columns.Add("Branch", typeof(string));
DataRow dr = orgTable.NewRow();
dr["EmpName"] = "Jack";
dr["Desig"] = "Chawki Daar";
dr["EmpFname"] = "Khain The";
dr["Salary"] = 12;
dr["Sex"] = "H";
dr["Branch"] = "Not Allowed";
orgTable.Rows.Add(dr);
SqlTransaction tran;
SqlConnection con = new SqlConnection("Constr");
con.Open();
tran = con.BeginTransaction();
SqlCommand cmd = new SqlCommand("select * from EmpDetail", con);
cmd.Transaction = tran;
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds,"EmpDat");
DataRow[] dr1 = ds.Tables[0].Select("empname='Jack'");
dr1[0]["empName"] = "Good Morning";
orgTable.AcceptChanges();
DataTable f = orgTable.GetChanges(DataRowState.Modified);
// con.Open();
SqlCommandBuilder sqlcmdBuild = new SqlCommandBuilder(da);
da.Update(ds.Tables[0]);

推荐答案

尝试使用Try catch，然后在catch块中提交SqlTransaction

像

Try using Try catch and then commit your SqlTransaction in catch block

something like

try
{
  //Your code here;
}
Catch(Exeception ex)
{
 //commit your SqlTransaction here;
}
