The one to three part name of the table to create. For an external table, only the table metadata is stored in SQL along with basic statistics about the file and or folder referenced in Hadoop or Azure blob storage. No actual data is moved or stored in SQL Server. CREATE EXTERNAL TABLE allows one or more column definitions. Both CREATE EXTERNAL TABLE and CREATE TABLE use the same syntax for defining a column. An exception to this, you cannot use the DEFAULT CONSTRAINT on external tables. For the full details about column definitions and their data types, see CREATE TABLE Transact SQL and CREATE TABLE on Azure SQL Database. The column definitions, including the data types and number of columns must match the data in the external files. If there is a mismatch, the file rows will be rejected when querying the actual data. For external tables that reference files in external data sources, the column and type definitions must map to the exact schema of the external file. When defining data types that reference data stored in HadoopHive, use the following mappings between SQL and Hive data types and cast the type into a SQL data type when selecting from it. The types include all versions of Hive unless stated otherwise.

The location starts from the root folder the root folder is the data location specified in the external data source. If you specify LOCATION to be a folder, a Poly. Base query that selects from the external table will retrieve files from the folder and all of its subfolders. Just like Hadoop, Poly. Base does not return hidden folders. It also does not return files for which the file name begins with an underline or a period. In this example, if LOCATIONwebdata, a Poly. Base query will return rows from mydata. It will not return mydata. It will not return hidden. To change the default and only read from the root folder, set the attribute lt polybase. This file is located under lt Sql. Bin. Root PolybaseHadoopConf with Sql. Bin. Root the bin root of SQl Server. For example, C Program FilesMicrosoft SQL ServerMSSQL1. XD1. 4MSSQLBinn. DATASOURCE externaldatasourcename. Specifies the name of the external data source that contains the location of the external data. This location is either a Hadoop or Azure blob storage. To create an external data source, use CREATE EXTERNAL DATA SOURCE Transact SQL. FILEFORMAT externalfileformatname. Specifies the name of the external file format object that stores the file type and compression method for the external data. To create an external file format, use CREATE EXTERNAL FILE FORMAT Transact SQL. Reject Options. You can specify reject parameters that determine how Poly. Base will handle dirty records it retrieves from the external data source. A data record is considered dirty if it actual data types or the number of columns do not match the column definitions of the external table. When you do not specify or change reject values, Poly. Base uses default values. This information about the reject parameters is stored as additional metadata when you create an external table with CREATE EXTERNAL TABLE statement. When a future SELECT statement or SELECT INTO SELECT statement selects data from the external table, Poly. Base will use the reject options to determine the number or percentage of rows that can be rejected before the actual query fails. The query will return partial results until the reject threshold is exceeded it then fails with the appropriate error message. REJECTTYPE value percentage. Clarifies whether the REJECTVALUE option is specified as a literal value or a percentage. REJECTVALUE is a literal value, not a percentage. The Poly. Base query will fail when the number of rejected rows exceeds rejectvalue. For example, if REJECTVALUE 5 and REJECTTYPE value, the Poly. Base SELECT query will fail after 5 rows have been rejected. REJECTVALUE is a percentage, not a literal value. A Poly. Base query will fail when the percentage of failed rows exceeds rejectvalue. The percentage of failed rows is calculated at intervals. REJECTVALUE rejectvalue. Specifies the value or the percentage of rows that can be rejected before the query fails. For REJECTTYPE value, rejectvalue must be an integer between 0 and 2,1. For REJECTTYPE percentage, rejectvalue must be a float between 0 and 1. REJECTSAMPLEVALUE rejectsamplevalue. This attribute is required when you specify REJECTTYPE percentage.
