Bulk insert update sql server c#




















Bulk Update: Step 1: put the data which you want to update and primary key in a list. Open ; command. Try out SqlBulkTools available on Nuget. Disclaimer: I'm the author of this library. ForCollection records.

WithTable "MyTable". Based on your name, and on the name of the Github account, I'd say you are the author of this SqlBulkTools library. There's nothing wrong with it, but you should disclose it clearly.

Otherwise it can be considered as spam and removed. Thank you! GregRTaylor, Dear the author, Mr. NET normal DataTable. I tried PrepareDatatable but I think examples seems not precise, sufficient I saw you're working on existing DataTable in your Github site. Can you guide me how to proceed or DataTable real example in more detail? Thank you very much for excellent SqlBulkTools! Gone from Git and nuget. Steve It is commercially available? Sorry Magnus, I needed the money at the time.

DateTime: sqlType. Append "datetime" ; break; case TypeCode. Decimal: case TypeCode. Double: sqlType. There are some good workarounds available for deleting and recreating the data context every updates, and that greatly improves the performance, but for hundreds of thousands of rows, it is still too slow.

SqlBulkCopy is very fast for these large insert or update batch operations. First convert a list of objects to a datatable by adding a row in the datatable for each object in the list and adding a column in the datatable for each of the object's properties, then copy the data from the list to the datatable. After this, we are executing the procedure by providing new values.

In the end, we will get the following output. Also, check: SQL Server logical operators and example. In this section, we will discuss how to create a stored procedure in SQL Server to insert date values in a table. And for this task, first, we will create a simple table in the database. In the above query, we have created a new table in the sqlserverguides database.

Next, we will create a stored procedure in SQL Server to insert a new record in this table including date value. In the above query, we are executing the stored procedure and we also provided the product name as American Cheese. Here is the final output. Read: SQL Server stored procedure if exists update else insert.

Bulk insert in SQL Server is a technique to move a large amount of data from a source to a new destination. So, in this tutorial, we understand how to create a stored procedure in SQL Server for the bulk insert operation. And for this, we will use the Customertbl table from the first section. Also, we will bulk insert the following data from CSV into the table. Moreover, you can also download the CSV file from the following download link.

Now, we have already covered this topic in detail in the following tutorial on SQL Server. SQL Server stored procedure insert into select. As we all know a stored procedure in SQL Server is a collection of queries that are used to achieve some goal. Moreover, it is a prepared SQL code that is compiled and stored in a database and can be reused multiple times.

Now, a stored procedure in SQL Server accepts two types of parameters. The first is an input parameter and, the second is the output parameter. For more details, refer to SQL Server stored procedure parameters. Now, to insert some data into a table, we have to use the input parameters in a SQL Server stored procedure.

Do not forget to assign the SQL parameter's type name to the name given to the above table type. In the SQL query, we select all the customers assigned to the table type parameter and insert them into the customer table. With this way, we execute one SQL query, which inserts all of the customers at once. SQL has a built-in mechanism to import a large volume of data, called Bulk Insert.

Besides the visible performance advantage over the other solutions, we can also easily tweak the behavior with some Options. When we write the customer list into the customers table, with the WriteToServer method on the SqlBulkCopy class, the method expects the collection to be a DataTable. We can see that there are multiple tactics to make a bulk insert fast er , and why a technique is faster than another.

Not that we always must use the fastest solution out there, but I think it's good to know the options that can be used in different scenarios. For smaller collections, it's probably good enough to use the solution that offers the best developer's ergonomics. By using a SQL Bulk Copy in our migration, we've won many hours that would otherwise be wasted while waiting on a migration run to complete.
