Skip header rows on SQL Data Warehouse PolyBase load
發佈日期： 二月 22, 2018
Delimited text files are often created with a header row that contains the column names. These rows need to be excluded from the data set during the load. Azure SQL Data Warehouse users can now skip these rows by using the First_Row option in the delimited text file format for PolyBase loads.
The First_Row option defines the first row that is read in every file loaded. By setting the value to 2, you effectively skip the header row for all files.
For more information, see the documentation for the CREATE EXTERNAL FILE FORMAT statement.
