Add a Solution. ZurdoDev Jul am. You can import into another table and have a matching column and then join to it to do your update. Accept Solution Reject Solution. I created some dummy data with over 1m records SQL. Copy Code. Posted Jul am CHill Add your solution here. OK Paste as. Treat my content as plain text, not as HTML.

But the issue is when you have to do a bulk update eg: for more than data. Anyway, thanks a lot. I'll refer the links you have shared. SahanDeSilva usally when you have a bulk update then you have a logic of what the change mean for example increment the age by 1 and then you don't need a specific case like here — No Idea For Name.

Anyway, thank you very much for sharing your opinion. The Overflow Blog. Podcast Helping communities build their own LTE networks. Podcast Making Agile work for data science. Featured on Meta.

If the data file is sorted in a different order, that is other than the order of a clustered index key or if there is no clustered index on the table, the ORDER clause is ignored. The column names supplied must be valid column names in the destination table. By default, the bulk insert operation assumes the data file is unordered. For optimized bulk import, SQL Server also validates that the imported data is sorted. By default, all the data in the data file is sent to the server as a single transaction, and the number of rows in the batch is unknown to the query optimizer.
Specifies that a table-level lock is acquired for the duration of the bulk-import operation. By default, locking behavior is determined by the table option table lock on bulk load.
Holding a lock for the duration of the bulk-import operation reduces lock contention on the table, in some cases can significantly improve performance.
For columnstore index. Each thread loads data exclusively into each rowset by taking an X lock on the rowset allowing parallel data load with concurrent data load sessions. Specifies a comma-separated values file compliant to the RFC standard. Specifies a character that will be used as the quote character in the CSV file. If not specified, the quote character " will be used as the quote character as defined in the RFC standard.
Specifies the full path of a format file. A format file describes the data file that contains stored responses created by using the bcp utility on the same table or view. The format file should be used if:. Specifies the field terminator to be used for char and widechar data files. Specifies the row terminator to be used for char and widechar data files.
To work around this behavior, use a format file to bulk import scientific notation float data into a decimal column. In the format file, explicitly describe the column as real or float data. For more information about these data types, see float and real Transact-SQL. A tab character is expected later in this sample. Therefore, a format file is necessary.
The format file must map the scientific notation float data to the decimal format of column c2. If a multiple-batch transaction is rolled back, every batch that the transaction has sent to SQL Server is rolled back. Before SQL Server For information about when row-insert operations that are performed by bulk import into SQL Server are logged in the transaction log, see Prerequisites for Minimal Logging in Bulk Import.
This is same as the maximum number of columns allowed in a table. If the number of pages to be flushed in a single batch exceeds an internal threshold, a full scan of the buffer pool might occur to identify which pages to flush when the batch commits.
