Synopsis

Creates a user defined message in sys.messages. This command does not support Azure SQL Database.

Description

This command provides a wrapper for the sp_addmessage system procedure that allows for user defined messages to be added to sys.messages.

Creates a new custom message on the sqldev01 instance with ID 70001, severity 16, text "test", and enables the log mechanism.

Example: 4

PS C:\> $server = Connect-DbaInstance sqldev01
PS C:\> $newMessage = New-DbaCustomError -SqlInstance $server -MessageID 70000 -Severity 16 -MessageText "test_70000"

Creates a new custom message on the sqldev01 instance with ID 70000, severity 16, and text "test_70000"
To modify the custom message at a later time the following can be done to change the severity from 16 to 20:

PS C:\> $original = $server.UserDefinedMessages | Where-Object ID -eq 70000
PS C:\> $messageID = $original.ID
PS C:\> $severity = 20
PS C:\> $text = $original.Text
PS C:\> $language = $original.Language
PS C:\> $removed = Remove-DbaCustomError -SqlInstance $server -MessageID 70000
PS C:\> $alteredMessage = New-DbaCustomError -SqlInstance $server -MessageID $messageID -Severity $severity -MessageText $text -Language $language -WithLog

The resulting updated message object is available in $alteredMessage.

Required Parameters

-SqlInstance

The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function
to be executed against multiple SQL Server 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.

-MessageID

An integer between 50001 and 2147483647.

-Severity

Severity level between 1 and 25.

-MessageText

Error message text with max length of 255 characters.

-Language

Language for this message. The valid values for Language are contained in the Name and Alias columns from sys.syslanguages.

-WithLog

Always write this message to the Windows application log and the SQL Server Error Log when it occurs.

-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 command were to run. No actions are actually performed.

-Confirm

Prompts you for confirmation before executing any changing operations within the command.
