Write-SqlTableData to import CSV into a Azure SQL Server table - azure

Question

The below command creates a new table, test for me but it doesn't insert any data into it.
Write-SqlTableData -TableName test -ServerInstance myservername -DatabaseName mydb -SchemaName dbo -Credential $mycreds -InputData $data -Force
This is the error message I get:
Write-SqlTableData : Cannot access destination table '[Mydb].[dbo].
[test]'.
At line:1 char:1
+ Write-SqlTableData -TableName test -ServerInstance myinstance
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : WriteError: ([dbo].[test]:Table) [Write-SqlTableData], InvalidOperationException
+ FullyQualifiedErrorId : WriteToTableFailure,Microsoft.SqlServer.Management.PowerShell.WriteSqlTableData
Any ideas are appreciated.
UPDATE
This is the code to populate data.
$data = import-csv 'C:\Users\azure-user\myfile.csv'
This is what the file looks like -
"State","ProviderNbr","Entity","Address","City","Zip","Phone","Ownership","StarRating"
"AL","017000","ALABAMA DEPARTMENT OF HEALTH HOME CARE","201 MONROE STREET, SUITE 1200", "ALABAMA", "32423", "3233233233", "Alabama", "4"

This is a weird one - as you say, in Azure Read-SqlTableData works but Write-SqlTableData doesn't. From the discussion on MSDN here I think its something to do with the Azure environment making it hard for the cmdlet to interpret the 'ServerInstance' parameter.
Example 5 in Microsoft's Write-SqlTableData documentation "Write data to an existing table of an Azure SQL Database" shows the way forwards - we need to instantiate an SMO reference to the Table and feed that to the cmdlet instead. Unfortunately the example Microsoft gives contains a small error (you can't do $table = $db.Tables["MyTable1"] to get the table, it doesn't work)
Here's a modified version of that example:
$csvPath = "C:\Temp\mycsv.csv"
$csvDelimiter = ","
# Set your connection string to Azure SQL DB.
$connString = 'Data Source=server;Persist Security Info=True'
$cred = Get-Credential -Message "Enter your SQL Auth credentials"
$cred.Password.MakeReadOnly()
$sqlcred = New-Object -TypeName System.Data.SqlClient.SqlCredential -ArgumentList $cred.UserName,$cred.Password
# Create a SqlConnection and finally get access to the SMO Server object.
$sqlcc = New-Object -TypeName System.Data.SqlClient.SqlConnection -ArgumentList $connString,$sqlcred
$sc = New-Object -TypeName Microsoft.SqlServer.Management.Common.ServerConnection -ArgumentList $sqlcc
$srv = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Server -ArgumentList $sc
# Get access to table 'MyTable1' on database 'MyDB'.
# Note: both objects are assumed to exists already.
$db = $srv.Databases["MyDB"]
$tableSmo = $db.Tables | Where-Object {$_.Name -eq "MyTable1"}
# leading comma makes an array with one item
# this makes PowerShell pass the entire contents of the file directly to the Write-SqlTableData cmdlet, which in turn can do a bulk-insert
, (Import-Csv -Path $pcsvPath -Delimiter $csvDelimiter) | Write-SqlTableData -InputObject $tableSmo
$sc.Disconnect()
If you're doing integrated security you can miss off all the $cred and $sqlcred stuff and just create the SqlConnection using $sqlcc = New-Object -TypeName System.Data.SqlClient.SqlConnection -ArgumentList $connString
Note: This worked for me with "A SQL Server running on a VM in Azure", in that I was having the same error as you, 'cannot access destination table' and this approach fixed it. I haven't tested it with an "Azure SQL Database" i.e. SQL Server as a service. But from the microsoft documentation it sounds like this should work.

According to my test, we can not use the command Write-SqlTableData to import CSV file to Azure SQL and we just can use it to import CSV file to on-premise SQL
So if you want to import CSV file to Azure SQL with powershell, you can use the command Invoke-SQLCmdto insert record on by one. For example:
$Database = ''
$Server = '.database.windows.net'
$UserName = ''
$Password = ''
$CSVFileName = ''
$text = "CREATE TABLE [dbo].[Colors2](
[id] [int] NULL,
[value] [nvarchar](30) NULL
) "
Invoke-SQLCmd -ServerInstance $Server -Database $Database -Username $UserName -Password $Password -Query $text
$CSVImport = Import-CSV -Path $CSVFileName
ForEach ($CSVLine in $CSVImport){
$Id =[int] $CSVLine.Id
$Vaule=$CSVLine.value
$SQLInsert = "INSERT INTO [dbo].[Colors2] (id, value)
VALUES('$Id', '$Vaule');"
Invoke-SQLCmd -ServerInstance $Server -Database $Database -Username $UserName -Password $Password -Query $SQLInsert
}
Invoke-SQLCmd -ServerInstance $Server -Database $Database -Username $UserName -Password $Password -Query "select * from [dbo].[Colors2]"
Besides, you also can use other ways ( such as BULK INSERT ) to implement it. For further information, please refer to https://learn.microsoft.com/en-us/sql/relational-databases/import-export/import-data-from-excel-to-sql?view=azuresqldb-current.
