Working with the bcp Command line Utility. The bcp utility is a command line tool that uses the Bulk Copy Program BCP API to bulk copy data between an instance of SQL Server and a data file. By using the utility, you can export data from a SQL Server database into a data file, import data from a data file into a SQL Server database, and generate format files that support importing and exporting operations. To use the bcp utility to perform these tasks, you can run a bcp command along with the appropriate arguments at a Command Prompt window. The command should conform to the following syntax bcptableviewquery   outqueryoutinformat   datafilenul   optionalargument. 3D Studio Max Keygen 141. As you can see, a bcp command requires three arguments. The first tableviewquery represents the data source or destination in a SQL Server database. You can use the bcp utility to export data from a table or view or through a query. If you specify a query, you must enclose it in quotation marks. Whenever a query operator needs to access a page eg. SH mode. Multiple operators can read the. Microsoft Access Append Query examples, SQL INSERT Syntax and errors to add multiple and single records into tables. In addition, you can import data into a table or view. If you import into a view, all columns within the view must reference a single table. Note that, when you specify a table or view, you must qualify the name with the database or schema names as necessary. The second argument in a bcp command outqueryoutinformat determines the commands mode direction. When you run a bcp command, you must specify one of the following four modes out The command exports data from a table or view into a data file. The command exports data retrieved through a query into a data file. The command imports data from a data file into a table or view. The command creates a format file based on a table or view. Format files are explained later in the article. The third argument in a bcp command datafilenul is the full path of the data file or, when a data file should not be specified, the nul value. If youre importing data, you must specify the file that contains the source data. If youre exporting data, you must specify the file that the data will be copied to. If the file does not exist, it will be created. When youre using the bcp utility to generate a format file, you do not specify a data file. Instead, you should specify nul in place of the data file name. In addition to the three required arguments, you can include one or more optional arguments when you issue a bcp command. The bcp utility supports numerous optional arguments, and the ones you include often depend on the mode you specify in the second argument. The remainder of this article provides examples that demonstrate how many of these arguments work. For a description of all the arguments supported by the bcp utility, see the topic bcp Utility in SQL Server Books Online. Exporting Data from a Table or View. As mentioned above, when you export data out of a table or view, you must specify the out option, along with the data source and destination file. The following bcp command copies data from the Employee table in the Adventure. Works. 20. 08 sample database and copies it to the Employee. Data. dat file. 1bcp. To retrieve data from the cache, add Cache to the table name. For example, to query cached data from the Sheet table, execute SELECT FROM SheetCache. I am running an ISS server, i have an access file located in CWCFAccess I am using this query to insert something INSERT INTO Arbejdsindsats MedarYdelID. On some Microsoft Access queries, I get the following message Operation must use an updatable query. Error 3073. I work around it by using temporary tables, but I. Adventure. Works. Human. Resources. Employeeout. C DataEmployee. Data. dat SlocalhostSql. Srv. 20. 08 TAs you would expect, the command includes the three required arguments the source table Adventure. Works. 20. 08. Human. IC125615.gif' alt='Operation Must Use An Updateable Query Access Insert Syntax' title='Operation Must Use An Updateable Query Access Insert Syntax' />Resources. Employee, the mode out, and the full path name of the destination data file C DataEmployee. Data. dat. If the data file exists when you run the command, any data within the file will be overwritten with the exported Employee information. If the file does not exist, it will be created and the data will be exported. The fourth argument in the example S localhostSql. Operation Must Use An Updateable Query Access Insert Syntax' title='Operation Must Use An Updateable Query Access Insert Syntax' />Srv. SQL Server. You do not have to include the instance name if the source database is in the default instance. And if the source database is in the default instance on the local machine, you do not have to specify the S argument at all, as in the following example 1bcp. Adventure. Works. Human. Resources. Employeeout. C DataEmployee. Data. dat TThe last argument in the preceding examples T indicates that a trusted connection should be used to connect to SQL Server. You should use this option if the SQL Server instance uses integrated security. If integrated security is not used, you should instead specify the U argument, along with the login ID of an account that can access the SQL Server instance. For example, the following bcp command specifies the login ID acct. SQL Server instance 1bcp. Adventure. Works. Human. Resources. Employeeout. C DataEmployee. Data. dat SlocalhostSql. Srv. 20. 08 Uacct. When you run this command, you will be prompted for a password. Alternatively, you can include the password in the command as well by specifying the P argument, along with the accounts password pw. Adventure. Works. Human. Resources. Employeeout. C DataEmployee. Data. dat SlocalhostSql. Srv. 20. 08 Uacct. Ppw. 12. 3However, Microsoft generally recommends that you do not include the P argument and instead wait to be prompted. But there might be circumstance when you want to pass in the password as part of the command. When you run any of the commands shown in the preceding examples, you will be prompted for information about each column in the source table or view. The following three prompts show you the type of data that you need to supply for each column Enterthefilestoragetypeoffield. Business. Entity. IDint Enterprefix lengthoffield. Business. Entity. ID0 Enterfieldterminatornone These prompts are what you receive for the Business. Entity. ID column in the Employee table. Notice that each prompt includes a recommended value, shown in the brackets. To accept the suggested setting, press Enter after you receive the prompt. Otherwise enter a value and then press Enter. Note, however, the recommended settings are generally your best options. For more information about each prompt, see the topic Specifying Data Formats for Compatibility by Using bcp in SQL Server Books Online. After you respond to each prompt for each column, you will be asked whether you want to save the format information and, if so, the full path name of the format file, as shown in the following two prompts DoyouwanttosavethisformatinformationinafileYnHostfilenamebcp. As you can imagine, it can get quite annoying having to supply format information each time you run a bcp command when exporting data. Fortunately, the bcp utility includes options that make this process much simpler. When defining your bcp command, you can include one of the following four arguments, which specify how the data should be formatted n native format The bcp utility retains the database native data types when bulk copying the data to the data file. Microsoft recommends that you use this format to bulk copy data between instances of SQL Server. However, you should use this format option only when the data file should not support extended or double byte character set DBCS characters. N Unicode native format The bcp utility uses the database native data types for non character data and uses Unicode for character data for the bulk copy operation. Microsoft recommends that you use this format to bulk copy data between SQL Server instances when the data file should support extended or DBCS characters. Unicode character format The bcp utility uses Unicode characters when bulk copying data to the data file.
