![]() For CSV data, one of the parameters in the schema.ini file would be "FORMAT=CSVDelimited". Jet treats text files as tables, with the schema defined by a schema.ini file that is located in the same directory as the data source. On 32-bit systems (SQL Server 2014 and below), it is possible to import CSV data into a SQL Server table without bulk-import optimizations by using OPENROWSET with the OLE DB Provider for Jet. csv file as a data file in a SQL Server bulk-import operation. To bulk import data from a Microsoft FoxPro or Visual FoxPro table (.dbf) file or a Microsoft Excel worksheet (.xls) file, you would need to convert the data into a CSV file that complies to the preceding restrictions. To be usable as a data file for bulk import, a CSV file must comply with the following restrictions:ĭata fields never contain the field terminator.Įither none or all of the values in a data field are enclosed in quotation marks (""). Note that the field terminator of a CSV file does not have to be a comma. Starting with SQL Server 2017, a CSV file can be used as the data file for a bulk import of data into SQL Server. For more information, see XML Format Files (SQL Server). To import data from data files with fixed-length or fixed-width fields, use a format file. To specify a subset of rows to import from a data file rather than the entire file, you can use a bcp command with the -F first_row switch and/or -L last_row switch. ![]() The data must be in row and column format.To import data from a data file, the file must meet the following basic requirements: To make bulk-exported table rows appear in a specific order in the data file, use the queryout option to bulk export from a query, and specify an ORDER BY clause.ĭata-File Format Requirements for Bulk Import ![]() Therefore, the table rows that are bulk exported in from an instance of SQL Server are not ordinarily guaranteed to be in any specific order in the data file. Microsoft SQL Server can use parallel scans to retrieve data. If that file name is already in use, the data that is being bulk copied to the data file overwrites the existing contents of the file.īulk export from a table or view to a data file requires SELECT permission on the table or view that is being bulk copied. When data is exported to a file, the bcp command creates the data file automatically by using the specified file name. Data-File Format Considerations for Bulk Exportīefore you perform a bulk-export operation by using the bcp command, consider the following: Use the same data formatting for fields of your data file. The formatting of each data field in this file shows the formatting required to bulk import data into the corresponding table column. If you are uncertain about how to format a data file for bulk importing, use the bcp utility to export data from the table into a data file.
