Examples

Example: 1

PS C:\> Set-DbaDbIdentity -SqlInstance SQLServer2017 -Database AdventureWorks2014 -Table 'Production.ScrapReason'

Connects to AdventureWorks2014 on instance SqlServer2017 using Windows Authentication and runs the command DBCC CHECKIDENT('Production.ScrapReason') to return the current identity value.

Example: 2

PS C:\> $cred = Get-Credential sqladmin
PS C:\> 'Sql1','Sql2/sqlexpress' | Set-DbaDbIdentity -SqlCredential $cred -Database AdventureWorks2014 -Table 'Production.ScrapReason'

Connects to AdventureWorks2014 on instances Sql1 and Sql2/sqlexpress using sqladmin credential and runs the command DBCC CHECKIDENT('Production.ScrapReason') to return the current identity value.

Example: 3

PS C:\> $query = "Select Schema_Name(t.schema_id) +'.' + t.name as TableName from sys.columns c INNER JOIN sys.tables t on t.object_id = c.object_id WHERE is_identity = 1"
PS C:\> $IdentityTables = Invoke-DbaQuery -SqlInstance SQLServer2017 -Database AdventureWorks2014 -Query $query
PS C:\> foreach ($tbl in $IdentityTables) {
PS C:\> Set-DbaDbIdentity -SqlInstance SQLServer2017 -Database AdventureWorks2014 -Table $tbl.TableName
PS C:\> }

Checks the current identity value for all tables with an Identity in the AdventureWorks2014 database on the SQLServer2017 and, if it is needed, changes the identity value.

Required Parameters

-SqlInstance

The target SQL Server instance or instances.

Optional Parameters

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.

-Database

The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed.
Only one database should be specified when using a RESEED value

-Table

The table(s) for which to check the current identity value.
Only one table should be specified when using a RESEED value

-ReSeedValue

The new reseed value to be used to set as the current identity value.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

-Confirm

Prompts you for confirmation before running the cmdlet.
