If guest users exist in a specific Azure AD and are part of a group that exists in SQL Database that has database permissions to execute the bcp command, their guest user alias is used for example, keith0 adventureworks.
Bulk import performance is improved if the data being imported is sorted according to the clustered index on the table, if any. 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, bcp assumes the data file is unordered.
For optimized bulk import, SQL Server also validates that the imported data is sorted. Used when -b is not specified, resulting in the entire data file being sent to the server as a single transaction.
The server optimizes the bulkload according to the value bb. TABLOCK Specifies that a bulk update table-level lock is acquired for the duration of the bulkload operation; otherwise, a row-level lock is acquired. This hint significantly improves performance because holding a lock for the duration of the bulk-copy operation reduces lock contention on the table.
By default, locking behavior is determined by the table option table lock on bulkload. If the target table is clustered columnstore index, TABLOCK hint is not required for loading by multiple concurrent clients because each concurrent thread is assigned a separate rowgroup within the index and loads data into it.
Please refer to columnstore index conceptual topics for details,. At some point, you will need to check the constraints on the entire table. If the table was nonempty before the bulk import operation, the cost of revalidating the constraint may exceed the cost of applying CHECK constraints to the incremental data. Therefore, we recommend that normally you enable constraint checking during an incremental bulk import. A situation in which you might want constraints disabled the default behavior is if the input data contains rows that violate constraints.
The only value that is possible is ReadOnly. If -K is not specified, the bcp utility will not support connectivity to a secondary replica in an Always On availability group. The -l option specifies the number of seconds before a login to SQL Server times out when you try to connect to a server.
The default login timeout is 15 seconds. The login timeout must be a number between 0 and If the value supplied is not numeric or does not fall into that range, bcp generates an error message. A value of 0 specifies an infinite timeout. In the absence of this parameter, the default is the last row of the file. A syntax error implies a data conversion error to the target data type.
A row that cannot be copied by the bcp utility is ignored and is counted as one error. If this option is not included, the default is The -m option also does not apply to converting the money or bigint data types.
This option does not prompt for each field; it uses the native values. This option offers a higher performance alternative to the -w option, and is intended for transferring data from one instance of SQL Server to another using a data file. It does not prompt for each field.
Use this option when you are transferring data that contains ANSI extended characters and you want to take advantage of the performance of native mode. If you export and then import data to the same table schema by using bcp. The warning can be ignored. One way to resolve this warning is to use -n instead of -N.
If this option is not used, the bcp command prompts for a password. If this option is used at the end of the command prompt without a password, bcp uses the default password NULL. To mask your password, do not specify the -P option along with the -U option. Instead, after specifying bcp along with the -U option and other switches do not specify -P , press ENTER, and the command will prompt you for a password.
This method ensures that your password will be masked when it is entered. Use this option to specify a database, owner, table, or view name that contains a space or a single quotation mark.
Enclose the entire three-part table or view name in quotation marks "". To specify a database name that contains a space or single quotation mark, you must use the -q option. For more information, see Remarks , later in this topic. Use this parameter to override the default row terminator. If you specify the row terminator in hexadecimal notation in a bcp.
For example, if you specify 0x, 0x41 will be used. By default, regional settings are ignored. If no server is specified, the bcp utility connects to the default instance of SQL Server on the local computer.
This option is required when a bcp command is run from a remote computer on the network or a local named instance. Use this parameter to override the default field terminator.

Description Generate a BCP format file based on source data file and destination table so we can bulk insert into some destination table columns with some corresponding fields in a source data file. Schema: schema name of the target table, string value, default to 'dbo' Table: target table name, string value, mandatory Mapping: a hashtable to link the field in data source file with the table column Source File: UNC path for the source file Format File: a UNC path for the generated format file, which can be used by BCP directly.
