![]() A single data file is used with two or more tables that have different schemas.The users do not have SELECT/INSERT permissions on one or more columns in the table.The target table contains at least one column for which either a default value is defined or NULL is allowed.The data file has a different number of fields that the target table has columns for example: The same data file is used as a source for multiple tables that have different schemas. However, for complex bulk-import situations, a format file is frequently required. For bcp or BULK INSERT, in simple situations, using a format file is optional and rarely necessary.SELECT * FROM OPENROWSET(BULK.) statement always requires a format file. bcp format nul -f myTeam.Xml -x -n -Tįor more information, see XML Format Files (SQL Server). This format file was created by using the following bcp command. The following XML format file uses the SQL Server native data format for the HumanResources.myTeam table. 14.0Ģ SQLNCHAR 2 100 "" 2 Name SQL_Latin1_General_CP1_CI_ASģ SQLNCHAR 2 100 "" 3 Title SQL_Latin1_General_CP1_CI_ASĤ SQLNCHAR 2 100 "" 4 Background SQL_Latin1_General_CP1_CI_ASįor more information, see Non-XML Format Files (SQL Server). The contents of this format file are as follows, starting with the major version number of SQL Server, and the table metadata information. For example, to specify a remote server named instance with Windows Authentication, use: bcp format nul -f myTeam.Fmt -n -T -S servername/instancename You can specify other instance and login information as desired, for more information see bcp Utility. The bcp command defaults to a local, default instance of SQL Server with Windows Authentication. The following non-XML format file uses the SQL Server native data format for the HumanResources.myTeam table. This table contains four columns: EmployeeID, Name, Title, and ModifiedDate.įor information about this table and how to create it, see HumanResources.myTeam Sample Table (SQL Server). These format files correspond to the HumanResources.myTeam table in the AdventureWorks2019 sample database. ![]() ![]() The following examples show the layout of a non-XML format file and of an XML format file. Format files are particularly useful when a mismatch exists between fields in the data file and columns in the table. Enables you to bulk import data without having to add or delete unnecessary data or to reorder existing data in the data file.Provides a flexible system for writing data files that requires little or no editing to comply with other data formats or to read data files from other software.In Azure Synapse Analytics and other cloud database platform integrations, accomplish data movement via the COPY statement in Azure Data Factory, or by using T-SQL statements such as COPY INTO and PolyBase. This syntax, including bulk insert, is not supported in Azure Synapse Analytics. ![]()
