sp_add_data_file_recover_suspect_db (Transact-SQL)

  • Άρθρο

Applies to: SQL Server

Adds a data file to a filegroup when recovery can't complete on a database due to insufficient space on the file group (error 1105). After the file is added, this stored procedure turns off the suspect setting and completes the recovery of the database. The parameters are the same as for ALTER DATABASE <database_name> ADD FILE.

Transact-SQL syntax conventions

Syntax

sp_add_data_file_recover_suspect_db [ @dbName = ] 'database'
    , [ @filegroup = ] N'filegroup_name'
    , [ @name = ] N'logical_file_name'
    , [ @filename = ] N'os_file_name'
    , [ @size = ] N'size'
    , [ @maxsize = ] N'max_size'
    , [ @filegrowth = ] N'growth_increment'
[ ; ]

Arguments

[ @dbName = ] 'database'

The name of the database. @dbName is sysname, with no default.

[ @filegroup = ] N'filegroup_name'

The filegroup you're adding the file to. @filegroup is nvarchar(260), with a default of NULL, which indicates the primary file.

[ @name = ] N'logical_file_name'

The name used in the SQL Server to reference the file. The name must be unique in the server. @name is nvarchar(260), with no default.

[ @filename = ] N'os_file_name'

The path and file name used by the operating system for the file. The file must reside on an instance of the Database Engine. @filename is nvarchar(260), with no default.

[ @size = ] N'size'

The initial size of the file. @size is nvarchar(20), with a default of NULL. Specify a whole number; don't include a decimal. The MB and KB suffixes can be used to specify megabytes or kilobytes. The default is MB. The minimum value is 512 KB. If @size isn't specified, the default is 1 MB.

[ @maxsize = ] N'max_size'

The maximum size to which the file can grow. @maxsize is nvarchar(20), with a default of NULL. Specify a whole number; don't include a decimal. The MB and KB suffixes can be used to specify megabytes or kilobytes. The default is MB.

If @maxsize isn't specified, the file grows until the disk is full. The Windows application log warns an administrator when a disk is about to become full.

[ @filegrowth = ] N'growth_increment'

The amount of space added to the file each time new space is required. @filegrowth is nvarchar(20), with a default of NULL. A value of 0 indicates no growth. Specify a whole number; don't include a decimal. The value can be specified in MB, KB, or percent (%). When % is specified, the growth increment is the specified percentage of the size of the file at the time the increment occurs. If a number is specified without an MB, KB, or % suffix, the default is MB.

If @filegrowth is NULL, the default value is 10%, and the minimum value is 64 KB. The size specified is rounded to the nearest 64 KB.

Return code values

0 (success) or 1 (failure).

Result set

None.

Permissions

Execute permissions default to members of the sysadmin fixed server role. These permissions aren't transferable.

Examples

In the following example, database db1 was marked suspect during recovery due to insufficient space (error 1105) in file group fg1.

USE master;
GO

EXEC sp_add_data_file_recover_suspect_db db1,
    fg1,
    file2,
    'C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Data\db1_file2.mdf',
    '1 MB';
