It always takes me a little bit of time to figure out how to construct a format file. For example suppose I had a SQL table like:. Notice that the text file has 5 fields, including a color field and a transmission field which are not in the table, and that the table has a model column not represented in the file, and that the order of the table columns does not match the order of the file fields. A possible. In the format file, the The 5 is the number of fields in each line of the textg file.
The 1,2,3,4,5 are each field in the file. A format file maps the fields of the data file to the columns of the table. The script below creates a test database and a table named myFirstImport. Alternatively, you can execute the following PowerShell script to create and populate the data file:. The following command will use the bcp utility to generate a non-xml format file, myFirstImport. To use a bcp command to create a format file, specify the format argument and use nul instead of a data-file path.
The format option also requires the -f option. Let us understand this with the help of an example. Suppose there is a table in the database named dbo. The table has an identity column named Rank. I have deleted some rows from the table. You can see my CSV file and the data in the table after the Bulk insert operation. In this case, I deleted all the data from the table and performed the bulk operation again.
After that, I got the identity values as it is in the table. You can see that table data in the below image:. In this way, you can import your existing identity values into a table with an identity column in SQL Server.
Sometimes, you may have data in a CSV file that is surrounded by double quotes i. For example:. Look at the below image for reference. Suppose, I have data in this format and I want to import this data into a table named dbo. After executing the above T-SQL query, my data got imported into the table without being enclosed between double-quotes. Thus, you might have learned how to bulk insert data having column values surrounded by double quotes into a SQL Server database table.
Read SQL Server function return table. Read SQL Server move database files. First you need to create the format file. I have put different data types in the example to show how they should be used.
