Author Nigel Rivett If the format of the file matches the table then it is simple to bcp the file without use of a format file. Bulk Copying SQL Server Data from Linux and UNIXThe SQL Server ODBC driver distribution includes a bulk copy program bcp, which lets you import and export large amounts of data from a table, view or result set in and out of SQL Server databases. The Easysoft bulk copy program is based on the one provided by Microsoft. If you have already used Microsofts bcp utility, you will recognise the Easysoft bcps command line arguments and be able to adapt existing Windows bcp scripts for Linux and UNIX platforms. Contents. Overviewbcp moves data from tables in the database to files on the file system and vice versa. SQL Server file type that allows the transfer of non character data. If you need to copy SQL Server data regularly, you can rerun your bcp commands by running them as a cron job. Linux and UNIX machines. You do not need to copy the exported data file to a Windows machine or make the file accessible to Windows by copying it to a Samba share. Importing and modifying Active Directory users with AD Bulk Users Importing users into Active Directory CSV, Excel The import file can be formatted using the CSV. When you use bcp to bulk copy data into a view, the usual rules about adding rows to a view apply only views in which all columns refer to the same table can be used as a destination. The bulk copy program is located in installationdireasysoftsqlserverbcp where installationdir is the Easysoft installation directory, by default usrlocal. To display bcps command line syntax, use the h argument. For example. cd usrlocaleasysoftsqlserverbcp. The source or target table for the bulk copy can be a one, two or three part table name or view name. For example, Adventure. Kara Damaged Lady English. Works. Human. Resources. Team is a three part table name, which contains the identifiers database name, schema name and object name. Use the in and out arguments to specify the direction of the bulk copy. To copy data from a file to a database table, use the in option. To copy data from a database table to a file, use the out option. If you do not include a path, bcp looks for creates datafile in the same directory as itself. If you are bulk copying data out of SQL Server, bcp will overwrite an existing datafile if it has the. The bcpoptions let you specify the SQL Server instance to connect to and the login to use to authenticate the connection. For example, this bcp command connects to a SQL Server Express instance using a Windows user name and password. Adventure. Works. BRU_setup_3.0.0.02.png' alt='Bulk Insert Multiple Csv Files' title='Bulk Insert Multiple Csv Files' />Sales. Currency out tmpCurrency. U mydomainmyuser P mypassword S mymachinesqlexpress. You do not have to specify a password on the command line. If you omit the P argument from the command line, bcp will prompt you for one when you run the command. For information about each bcp argument, see the SQL Server ODBC driver documentation. Exporting Data from a Table or Viewbcp has two modes of operation interactive and noninteractive. In interactive mode, a series of prompts asks you to describe each column in the source table or view you are exporting data from or importing data to. The following bcp command exports data from the Human. Resources. my. Team table in the Adventure. Works sample database to the my. Team. dat file. bcp Adventure. Works. Human. Resources. Team out tmpmy. Team. U mydomainmyuser S myserversqlexpress. The default mode is interactive and so bcp prompts you to describe each column. For example. Enter the file storage type of field Employee. ID smallint. enter the prefix length of field Employee. ID 0. enter the field terminator none. To accept the recommended responses shown in square brackets, press RETURN. At the end of the interactive session, bcp prompts you to save this information in a text based format file for future use. If you do this, reentering previous format responses interactively is not necessary. For more information about format files, see later in this article. In noninteractive mode, you are not prompted for format information. To run bcp in noninteractive mode, you include one of the following arguments, which specify in advance how data should be formatted Data format. Argument. Description. Native n. Use Native format when copying data between SQL Server tables and the data does not contain extended or double byte character set DBCS characters. Unicode Native NUse Native format when copying data between SQL Server tables and the data contains extended or DBCS characters. Character c. Use Character format when copying data between SQL Server and other applications. Unicode Character w. Use Unicode Character format when copying data between SQL Server tables and the data is Unicode but does not contain extended or double byte character set DBCS characters. These commands copy data between SQL Server instances. The character data in the table is ASCII, and so Native format n is specified. Because bcp is being run in noninteractive mode, it does not prompt for format information. Adventure. Works. Human. Resources. Team out my. Team. U mydomainmyuser S mymachinedevelopment n.

If you do not want to export an entire table then you can use bcps queryout argument to retrieve data through a query instead. An example bcp command that executes a query is shown later in this article. This example bcp command calls a procedure rather than executes a query. The procedure returns a result set, which is written to a file. EXEC Adventure. Works. Get. Employee. Managers 5. Employees. txt U mymachinemyuser S mymachinesqlexpress c. Importing Data into a Table. To import data into a table or updatable view, you specify the table view and the in argument. The following example command imports comma separated data that has been exported from an Open. Office Calc spreadsheet. Adventure. Works. Human. Resources. Team in my. Team. Team.

If you get the error Client unable to establish connection eof reading input file, the row terminator in the data file you are attempting to import is different to the one bcp expects. Loading data files with SQL Servers BULK INSERT statement. In my previous tip, I discussed how to use the bcp utility in SQL Server to bulk copy data from a file into a table.

You also agree that your personal information may be transferred and processed in the United States, and that you have read and agree to the Terms of Use and the Privacy Policy. In this tip, I discuss the BULK INSERT statement, which is a Transact SQL statement that lets you bulk load a data file into a SQL Server database. I also provide several examples of BULK INSERT statements to copy data into a SQL Server table. These examples have been tested in SQL Server 2. SQL Server 2. 00. I used the Adventure. Works sample database. To run the examples in this tip, I first used the following bcp command to create my source data file bcp SELECT Employee. ID, First. Name, Last. Name, Job. Title FROMAdventure. Works. Human. Resources. Employee WHERE Employee. ID 1 queryout. C DataEmployees. T t,The command retrieves data from the v. Employee view in the Adventure. Works database and saves it to the C DataEmployees. Next, I used the following T SQL script to create the Employees table in the Adventure. Works database USE Adventure. Works. GOIF OBJECTID NEmployees, NU IS NOT NULLDROP TABLE dbo. Employees. GOCREATE TABLE dbo. Employees Employee. ID INT IDENTITY PRIMARY KEY,First. Name NVARCHAR5. 0 NOT NULL,Last. Name NVARCHAR5. 0 NOT NULL,Job. Title NVARCHAR5. NOT NULL,CONSTRAINT ck. Job. Title CHECK Job. Title lt Marketing Technician Note that, in the table definition, the Employee. ID column is configured as an IDENTITY column and the Job. Title column is configured with a check constraint. Ive included both components to demonstrate the options supported by the BULK INSERT statement. The syntax for the BULK INSERT statement is straightforward BULK INSERT Table. View FROM Data. File WITH option ,. As you can see, the BULK INSERT keywords are followed by the name of the table or view. That name should be qualified with the database and schema names as necessary. Following the name is the FROM clause, which specifies the path and file name of the data file. After the FROM clause, you should include any of the appropriate options supported by the BULK INSERT statement. The following statement provides an example of the various elements included in the syntax BULK INSERT Adventure. Works. dbo. Employees. FROM C DataEmployees. WITHFIELDTERMINATOR ,This statement retrieves data from the C DataEmployees. Employees table in the Adventure. Works database. First, I defined the target table in the BULK INSERT clause. In this case, I used the tables fully qualified name. Next, I specified the file name in the FROM clause. Note that I enclosed the file name in single quotes, so it is treated as a string value. The next step is to add the WITH clause, which includes the FIELDTERMINATOR option enclosed in parentheses. Because the source file is a comma delimited file, I must specify that each field is terminated with a comma. I do so by including a comma enclosed in single quotes after the equal sign. Without specifying the FIELDTERMINATOR option for a. BULK INSERT statement would not know how to retrieve the data and the statement would fail. These are the general steps for using a SQL Server BULK INSERT statement. But the statement supports nearly 2. Ive shown here. For instance, the following BULK INSERT statement includes two options FIELDTERMINATOR and CHECKCONSTRAINTS BULK INSERT Adventure. Works. dbo. Employees. FROM C DataEmployees. WITHFIELDTERMINATOR ,CHECKCONSTRAINTSUnlike the FIELDTERMINATOR option, the CHECKCONSTRAINTS option takes no arguments. It simply tells the BULK INSERT statement to enforce all CHECK constraints on the table or view before inserting data. Otherwise, these constraints are not enforced. Note that PRIMARY KEY, FOREIGN KEY, UNIQUE, and NOT NULL constraints are always enforced. If the CHECKCONSTRAINTS option is included in the BULK INSERT statement, the statement will fail when a CHECK constraint is violated. You may have noticed in the preceding example that, if you include multiple options in the WITH clause, you must separate these options with a comma. The following BULK INSERT statement, for example, builds on the previous example by adding the KEEPIDENTITY option BULK INSERT Adventure. Works. dbo. Employees. FROM C DataEmployees. WITHFIELDTERMINATOR ,CHECKCONSTRAINTS,KEEPIDENTITYThe KEEPIDENTITY option specifies that identity values should be preserved when inserted into the target table. If you were to run the previous examples, you might notice that new identity values were inserted for the Employee. ID column. By using KEEPIDENTITY, however, the Employee. ID values saved to the Employees. In addition to the data focused options shown in the examples above, the BULK INSERT statement also supports options that control the batch load process. The following statement, for example, includes the BATCHSIZE option, which specifies the number of rows in a batch BULK INSERT Adventure. Works. dbo. Employees. FROM C DataEmployees. WITHFIELDTERMINATOR ,CHECKCONSTRAINTS,KEEPIDENTITY,BATCHSIZE 5. When you run this statement, the rows are inserted into the target table in batches of 5. You can verify this in the messages returned by the query. The preceding statement returns the following messages 5. As you can see, the data is now loaded in 5. As mentioned previously, the BULK INSERT statement doe SQL Server 2. You can find details about each option by referring to the BULK INSERT Transact SQL topic in SQL Server Books Online. The topic also discusses how to call a format file when bulk loading your data. A format file is useful when the data file contains a different number of columns than does your target table the columns are in a different order, the column delimiters vary or there are anomalies in the data format. For a basic BULK INSERT operation, however, the examples above should provide many of the details you need to get started loading data from various types of data files.
