[英]Adding bulk values to SQL Server database with c# winform
I'm using SQL Server 2008 Express. 我正在使用SQL Server 2008 Express。
What is the best way to import bulk values into the database from a C# app? 从C#应用程序将批量值导入数据库的最佳方法是什么?
Right now I have some textboxes and I can import data without any problem. 现在,我有一些文本框,可以毫无问题地导入数据。 And I would like to import not only one row ,by "click to a button" but 3 or 4. 我不仅想通过“单击按钮”导入一行,而且要导入3或4。
Please help me! 请帮我!
For 3 or 4 rows, I would suggest setting up a SqlCommand
with a parameterized insert statement, creating and binding parameters for the inserted columns, and then calling ExecuteNonQuery
. 对于3或4行,我建议使用参数化的insert语句设置SqlCommand
,为插入的列创建和绑定参数,然后调用ExecuteNonQuery
。 You can retain the same SqlCommand
and SqlParameters
objects, reassign new values to the SqlParameter
s, and then do the next ExecuteNonQuery
for the next row. 您可以保留相同的SqlCommand
和SqlParameters
对象,将新值重新分配给SqlParameter
,然后对下一行执行下一个ExecuteNonQuery
。
However, if you are doing a much larger insert (as in 100k rows at a time), you should look at using SqlBulkCopy
- this allows for high performance bulk inserts (and only inserts) into a table. 但是,如果您要进行大得多的插入(一次插入10万行),则应考虑使用SqlBulkCopy
这允许在表中进行高性能的大容量插入(并且仅插入)。
