如何将Excel数据插入SQL Server表

问题描述：

我有Excel工作表，并且有1000条记录，我想在SQL表中插入之前验证重复的ID和名称，请帮助我.

如果记录存在，那么我将移至下一条记录，然后插入.

I have Excel sheet and have 1000 records are there, i want to verify duplicate id and name, before insertin in SQL Table, Please Help me.

If the record exists, then i will move to the next record and then insert.

Excel column
------------
Emp_Id   
Emp_Name

Table Column
-------------
Emp_ID
Emp_Name

Emp_Id应从excel检查重复项，然后插入.如果发现重复，则应检查并插入下一行.

Emp_Id Should check the duplication from the excel and then insert. if duplication founds then it should check and insert the next rows.

How to do this..?

答

假定您已将文件中的数据读入某种类型的集合中，例如List< empdata&gt ;，其中EmpData是您的对象我会做的(几乎是伪代码):

Assuming you have read the data from the file into some sort of collection say List<empdata>, where EmpData is your object here is what I would do (in almost pseudocode):

List<empdata> emps = ParseExcelData();
foreach(EmpData emp in emps)
{
   //if this emp doesn't exist in the DB already, the function would return null
   //but if its not null, then it will just skip and move to next record repeating    the same process
   if (GetEmpDataFromDatabaseById(emp.Emp_ID) == null )
   {
      SaveEmpData(emp);
   }
}</empdata>

您将必须编写自己的ParseExcelData，GetEmpDataFromDatabaseById和SaveEmpData方法.

希望这会有所帮助.

干杯.

You would have to write your own ParseExcelData, GetEmpDataFromDatabaseById and SaveEmpData methods.

Hope this helps.

Cheers.
