<#
    .SYNOPSIS
        Writes data to a SQL Server Table.
         
    .DESCRIPTION
        Writes a .NET DataTable to a SQL Server table using SQL Bulk Copy.
         
    .PARAMETER SqlInstance
        The SQL Server instance.
         
    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
         
    .PARAMETER Database
        The database to import the table into.
         
    .PARAMETER InputObject
        This is the DataTable (or datarow) to import to SQL Server.
         
    .PARAMETER Table
        The table name to import data into. You can specify a one, two, or three part table name. If you specify a one or two part name, you must also use -Database.
         
        If the table does not exist, you can use -AutoCreateTable to automatically create the table with inefficient data types.
         
    .PARAMETER Schema
        Defaults to dbo if no schema is specified.
         
    .PARAMETER BatchSize
        The BatchSize for the import defaults to 5000.
         
    .PARAMETER NotifyAfter
        Sets the option to show the notification after so many rows of import
         
    .PARAMETER AutoCreateTable
        If this switch is enabled, the table will be created if it does not already exist. The table will be created with sub-optimal data types such as nvarchar(max)
         
    .PARAMETER NoTableLock
        If this switch is enabled, a table lock (TABLOCK) will not be placed on the destination table. By default, this operation will lock the destination table while running.
         
    .PARAMETER CheckConstraints
        If this switch is enabled, the SqlBulkCopy option to process check constraints will be enabled.
         
        Per Microsoft "Check constraints while data is being inserted. By default, constraints are not checked."
         
    .PARAMETER FireTriggers
        If this switch is enabled, the SqlBulkCopy option to fire insert triggers will be enabled.
         
        Per Microsoft "When specified, cause the server to fire the insert triggers for the rows being inserted into the Database."
         
    .PARAMETER KeepIdentity
        If this switch is enabled, the SqlBulkCopy option to preserve source identity values will be enabled.
         
        Per Microsoft "Preserve source identity values. When not specified, identity values are assigned by the destination."
         
    .PARAMETER KeepNulls
        If this switch is enabled, the SqlBulkCopy option to preserve NULL values will be enabled.
         
        Per Microsoft "Preserve null values in the destination table regardless of the settings for default values. When not specified, null values are replaced by default values where applicable."
         
    .PARAMETER Truncate
        If this switch is enabled, the destination table will be truncated after prompting for confirmation.
         
    .PARAMETER BulkCopyTimeOut
        Value in seconds for the BulkCopy operations timeout. The default is 30 seconds.
         
    .PARAMETER RegularUser
        Deprecated - now all connections are regular user (don't require admin)
         
    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.
         
    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
         
    .PARAMETER 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.
         
    .PARAMETER UseDynamicStringLength
        By default, all string columns will be NVARCHAR(MAX).
        If this switch is enabled, all columns will get the length specified by the column's MaxLength property (if specified)

    .EXAMPLE
        $DataTable = Import-Csv C:\temp\customers.csv | ConvertTo-DbaDataTable
        Write-DbaDataTable -SqlInstance sql2014 -InputObject $DataTable -Table mydb.dbo.customers
         
        Performs a bulk insert of all the data in customers.csv into database mydb, schema dbo, table customers. A progress bar will be shown as rows are inserted. If the destination table does not exist, the import will be halted.
         
    .EXAMPLE
        $DataTable = Import-Csv C:\temp\customers.csv | ConvertTo-DbaDataTable
        $DataTable | Write-DbaDataTable -SqlInstance sql2014 -Table mydb.dbo.customers
         
        Performs a row by row insert of the data in customers.csv. This is significantly slower than a bulk insert and will not show a progress bar.
         
        This method is not recommended. Use -InputObject instead.
         
    .EXAMPLE
        $DataTable = Import-Csv C:\temp\customers.csv | ConvertTo-DbaDataTable
        Write-DbaDataTable -SqlInstance sql2014 -InputObject $DataTable -Table mydb.dbo.customers -AutoCreateTable
         
        Performs a bulk insert of all the data in customers.csv. If mydb.dbo.customers does not exist, it will be created with inefficient but forgiving DataTypes.
         
    .EXAMPLE
        $DataTable = Import-Csv C:\temp\customers.csv | ConvertTo-DbaDataTable
        Write-DbaDataTable -SqlInstance sql2014 -InputObject $DataTable -Table mydb.dbo.customers -Truncate
         
        Performs a bulk insert of all the data in customers.csv. Prior to importing into mydb.dbo.customers, the user is informed that the table will be truncated and asks for confirmation. The user is prompted again to perform the import.
         
    .EXAMPLE
        $DataTable = Import-Csv C:\temp\customers.csv | ConvertTo-DbaDataTable
        Write-DbaDataTable -SqlInstance sql2014 -InputObject $DataTable -Database mydb -Table customers -KeepNulls
         
        Performs a bulk insert of all the data in customers.csv into mydb.dbo.customers. Because Schema was not specified, dbo was used. NULL values in the destination table will be preserved.
         
    .EXAMPLE
        $passwd = ConvertTo-SecureString "P@ssw0rd" -AsPlainText -Force
        $AzureCredential = New-Object System.Management.Automation.PSCredential("AzureAccount"),$passwd)
        $DataTable = Import-Csv C:\temp\customers.csv | ConvertTo-DbaDataTable
        Write-DbaDataTable -SqlInstance AzureDB.database.windows.net -InputObject $DataTable -Database mydb -Table customers -KeepNulls -Credential $AzureCredential -BulkCopyTimeOut 300
         
        This performs the same operation as the previous example, but against a SQL Azure Database instance using the required credentials.
         
    .EXAMPLE
        $process = Get-Process | ConvertTo-DbaDataTable
        Write-DbaDataTable -InputObject $process -SqlInstance sql2014 -Database mydb -Table myprocesses -AutoCreateTable
         
        Creates a table based on the Process object with over 60 columns, converted from PowerShell data types to SQL Server data types. After the table is created a bulk insert is performed to add process information into the table.
         
        This is an example of the type conversion in action. All process properties are converted, including special types like TimeSpan. Script properties are resolved before the type conversion starts thanks to ConvertTo-DbaDataTable.
