SQL Server Provider

Store uploaded files directly in a SQL Server database. Configure the connection string and table schema.

What you should see: files stored as rows in SQL Server rather than on disk. Only the server-side provider changes — the browser code is identical. Accepts up to 50 MB.

<!-- Server-side: store files in SQL Server -->
// In Program.cs
builder.Services.AddCoreUpload(options =>
{
 options.UseStorageProvider<SqlServerStorageProvider>(config =>
 {
 config.ConnectionString =
 builder.Configuration.GetConnectionString("Default");
 config.TableName = "UploadedFiles";
 config.SchemaName = "dbo";
 });
});

// Table schema:
// CREATE TABLE dbo.UploadedFiles (
// Id UNIQUEIDENTIFIER PRIMARY KEY DEFAULT NEWID(),
// FileName NVARCHAR(256) NOT NULL,
// ContentType NVARCHAR(128),
// FileSize BIGINT,
// FileData VARBINARY(MAX),
// CreatedAt DATETIME2 DEFAULT GETUTCDATE()
// );
