be processed.

Required? false

-EnableException [<Switch>]

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.

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'

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
