The table variable does not allow to create an explicit index. Use smart snippets to quickly create copies of your database for development or testing purposes, and to generate and execute CREATE and INSERT scripts. In some cases, your target table will include more values than are in the data file, as is sometimes the case when you have nullable columns or columns with default or computed values. For example, if a database was created with an initial size of 8MB but grew to 4GB, the smallest you can shrink the database to is the original size of 8MB. Next, create a new script file (backup4.sql), and populate the file with the code below. Instead, you can extract the SQL script from SSSM to perform the task. I then modified the format file to support the Contacts4 table, as shown in the following: The first modification I made is to change the numbering in the sixth column of the format file (the numbering for the server column order). Create free Team sqlcmd -S "SERVERNAME\INSTANCENAME" -U User -P pwd -d DatabaseName -Q "SELECT TOP 5 Id FROM dbo.MyTable;" sqlcmd -S SERVERNAME\INSTANCENAME -U User -P pwd -d Invoking backup7.sql script file will generate the backup file accordingly, as shown below.

If youre exporting data, you must specify the file that the data will be copied to. If the protocol is not specified in some other way, sqlcmd will use the network protocol determined by the protocol order in SQL Server Configuration Manager. This tutorial creates a new backup file, wwi_2.bak, in the previously created /var/opt/mssql/backup directory. For example, the following bcp command species that each field be terminated with a comma: As you can see, the command includes the -t argument following by a comma, so each field in the data file will be terminated with a comma, rather than a tab. Each format file contains formatting information about the data in the data file as well as information about the target database table. To match the columns to the fields in the data file, you must make sure that the SOURCE element value matches the appropriate ID value in the FIELD elements. The code below will backup the AdventureWorksLT2019 database with the name 20220206_1705_AdventureWorksLT2019.bak.
