Azure ARM dependencies between nested templates

I've created a template that has two nested templates. The first nested template defines an SQL server as:

{
  "name": "[variables('sqlServerName')]",
  "type": "Microsoft.Sql/servers",
  "location": "[resourceGroup().location]",
  "apiVersion": "2014-04-01-preview",
  "dependsOn": [],
  "tags": {
    "displayName": "SqlServer"
  },
  "properties": {
    "administratorLogin": "[parameters('sqlAdministratorLogin')]",
    "administratorLoginPassword": "[parameters('adminLoginPassword')]"
  },
  "resources": [
    {
      "name": "AllowAllWindowsAzureIps",
      "type": "firewallrules",
      "location": "[resourceGroup().location]",
      "apiVersion": "2014-04-01-preview",
      "dependsOn": [
        "[resourceId('Microsoft.Sql/servers', variables('sqlServerName'))]"
      ],
      "properties": {
        "startIpAddress": "0.0.0.0",
        "endIpAddress": "0.0.0.0"
      }
    }
  ]
}

and the second nested template defines a database that will be hosted on the above server:

{
  "name": "[concat(parameters('sqlServerName'), '/', 'Admin')]",
  "type": "Microsoft.Sql/servers/databases",
  "location": "[resourceGroup().location]",
  "apiVersion": "2014-04-01-preview",
  "dependsOn": [],
  "tags": {
    "displayName": "AdminApiDb"
  },
  "properties": {
    "collation": "[parameters('AdminApiDbCollation')]",
    "edition": "[parameters('AdminApiDbEdition')]",
    "maxSizeBytes": "1073741824",
    "requestedServiceObjectiveName": "[parameters('AdminApiDbRequestedServiceObjectiveName')]"
  }
}

And then my parent template looks like:

 {
  "name": "Shared",
  "type": "Microsoft.Resources/deployments",
  "apiVersion": "2016-09-01",
  "dependsOn": [],
  "properties": {
    "mode": "Incremental",
    "templateLink": {
      "uri": "[concat(parameters('_artifactsLocation'), '/', variables('SharedTemplateFolder'), '/', variables('SharedTemplateFileName'), parameters('_artifactsLocationSasToken'))]",
      "contentVersion": "1.0.0.0"
    }
},
{
  "name": "Admin",
  "type": "Microsoft.Resources/deployments",
  "apiVersion": "2016-09-01",
  "dependsOn": [
    "[concat('Microsoft.Resources/deployments/', 'Shared')]"
  ],
  "properties": {
    "mode": "Incremental",
    "templateLink": {
      "uri": "[concat(parameters('_artifactsLocation'), '/', variables('AdminTemplateFolder'), '/', variables('AdminTemplateFileName'), parameters('_artifactsLocationSasToken'))]",
      "contentVersion": "1.0.0.0"
    }
}

But when trying to deploy this it errors with:

The resource 'Microsoft.Sql/servers/mysqlserver' is not defined in the template.

How can I get it to the database to see the sql server in the sibling template? It does deploy the sql server with the correct name, so it's not a naming issue.

Thanks

There is absolutely no sense in creating nested templates for those resources, but if you want to do it that way, you should define the actual nested template invocation to depend on one another (so second nested template should depend on the first one) in the parent template, not the resource inside the nested templates.

You can only use dependsOn for resources in the template, and those resources are not in the template.

ok, your template contains another bug, you cannot use reference function for the resources not in the same template without specifying the api version.

"[concat('Data Source=tcp:', reference(concat('Microsoft.Sql/servers/', parameters('sqlserverName')), '2014-04-01-preview').fullyQualifiedDomainName, ',1433;Initial Catalog=Admin', ';User Id=', parameters('sqlAdministratorLogin'), '@', reference(concat('Microsoft.Sql/servers/', parameters('sqlserverName')), '2014-04-01-preview').fullyQualifiedDomainName, ';Password=', parameters('sqlAdministratorLoginPassword'), ';')]",

you can use reference function without the api version if the resource is in the same template
