Synapse system dacpac missing extended procedures

How to reference system stored procedure like sp_executesql ?

I’m getting this warning for my stored procedure which uses sp_executesql :

Build warning SQL71502: SqlProcedure: [meta].[usp_test] contains an unresolved reference to an object. Either the object does not exist or the reference is ambiguous because it could refer to any of the following objects: [dbo].[sp_executesql] or [meta].[sp_executesql].

I added a reference to the master database but that doesn’t solve the warning, the project file looks like:

<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build">
  <Sdk Name="Microsoft.Build.Sql" Version="0.1.3-preview" />
  <PropertyGroup>
    <Name>synapse</Name>
    <ProjectGuid>{8688EAA4-F8D6-4AB6-9122-F4EC5F406D3B}</ProjectGuid>
    <DSP>Microsoft.Data.Tools.Schema.Sql.SqlDwDatabaseSchemaProvider</DSP>
    <ModelCollation>1033, CS</ModelCollation>
    <DefaultCollation>SQL_Latin1_General_CP1_CS_AS</DefaultCollation>
  </PropertyGroup>
  <Target Name="BeforeBuild">
    <Delete Files="$(BaseIntermediateOutputPath)\project.assets.json" />
  </Target>
  <ItemGroup>
    <ArtifactReference Include="./_build/AzureDw_master.dacpac">
      <SuppressMissingDependenciesErrors>False</SuppressMissingDependenciesErrors>
      <DatabaseVariableLiteralValue>master</DatabaseVariableLiteralValue>
    </ArtifactReference>
  </ItemGroup>
</Project>

I tried to reference sys.sp_executesql (which actually “works” in synapse dedicated pool), but which the compiler still doesn’t like:

stdout:  Build warning SQL71502: SqlProcedure: [meta].[usp_test] has an unresolved reference to object [sys].[sp_executesql]. 

I found this reference from visual studio 2019 where apparently a bug was solved back in 2020, but it doesn’t seem to work for me in vscode mssql extension: https://developercommunity.visualstudio.com/t/Warning-in-VS2019-:-object-does-not-exis/824096.

That same page hints that including a “master” dacpac doesn’t actually work for synapse all together.

@jbtcode I took a look at the master.dacpac for Synapse and noticed it’s missing some elements. It’s actually missing all of the extended procedures including sp_executesql. We’ll work on getting those added correctly.

Microsoft.Build.Sql 0.1.9-preview has been released. It supports PackageReferences to the Microsoft.SqlServer.Dacpacs Nuget packages (there are also Azure or Synapse variants depending on your target platform). You can reference it via

<PackageReference Include="Microsoft.SqlServer.Dacpacs.Synapse" Version="130.0.0" />

The other attributes such as SuppressMissingDependenciesErrors and DatabaseVariableLiteralValue can be transferred to the PackageReference as well.

You can find more documentation here: https://learn.microsoft.com/en-us/sql/azure-data-studio/extensions/sql-database-project-extension-sdk-style-projects?view=sql-server-ver16#package-references
