Default authentication is Integrated Windows Authetication. System.Data.SqlClient. .Parameter ConnectionName The name to associate with the newly created connection. This connection will be used with other cmdlets when specifying -ConnectionName <name>. If you don't specify one, it will be set to the default. .Parameter ConnectionString Specifies a provider specific connectionstring to be used. .Parameter CommandTimeout The default command timeout to be used for all commands executed against this connection. .Parameter DataSource The datasource for the connection. .Parameter InitialCatalog Database catalog connecting to. .Parameter UserName Username to connect as. .Parameter Password Password for the connecting user. .Parameter AzureAD Use this when connecting to an Azure SQL Database and you are using Azure AD credentials. You can specify the credentials either by using the UserName/Password parameters or by passing in a credential object to the Credential parameter. .Parameter Credential Credential object containing the SQL user/pass. #> [CmdletBinding(DefaultParameterSetName="default")] Param([Parameter(ValueFromPipelineByPropertyName)][Alias("cn")][string]$ConnectionName = "default" , [Parameter(ValueFromPipelineByPropertyName)][int]$CommandTimeout = 30 , [Parameter(ValueFromPipelineByPropertyName, ParameterSetName="default", Position=0)] [Parameter(ValueFromPipelineByPropertyName, ParameterSetName="user", Position=0)] [Parameter(ValueFromPipelineByPropertyName, ParameterSetName="cred", Position=0)] [Alias("SqlInstance","SqlServer","DataSource")][string]$Server = "localhost" , [Parameter(ValueFromPipelineByPropertyName, ParameterSetName="default", Position=1)] [Parameter(ValueFromPipelineByPropertyName, ParameterSetName="user", Position=1)] [Parameter(ValueFromPipelineByPropertyName, ParameterSetName="cred", Position=1)] [Alias("SqlDatabase","InitialCatalog")][string]$Database = "master" , [Parameter(Mandatory, ValueFromPipelineByPropertyName, ParameterSetName="user")] [string]$UserName , [Parameter(Mandatory, ValueFromPipelineByPropertyName, ParameterSetName="user")] [string]$Password , [Parameter(Mandatory, ValueFromPipelineByPropertyName, ParameterSetName="cred")] [Parameter(ValueFromPipelineByPropertyName, ParameterSetName="conn")] [pscredential]$Credential , [Parameter(ParameterSetName="user")] [Parameter(ParameterSetName="cred")][Switch]$AzureAD , [Parameter(Mandatory, ValueFromPipelineByPropertyName, ParameterSetName="Conn")][string]$ConnectionString) If($Script:Connections.ContainsKey($ConnectionName)) { Close-SqlConnection $ConnectionName } If($ConnectionString) { $sb = [System.Data.SqlClient.SqlConnectionStringBuilder]::new($ConnectionString) } Else { $sb = [System.Data.SqlClient.SqlConnectionStringBuilder]::new() If($Server) { $sb.Server = $Server } If($Database) { $sb.Database = $Database } If($UserName) { Write-Warning "You are using -UserName and -Password, these options are deprecated and will be removed in the future.
