SQL Server VARBINARY Type Overview

  • VARBINARY(n): Up to n bytes (1 ≤ n ≤ 8000)
  • VARBINARY(MAX): Up to 2 GB (recommended for PDF files)

Step-by-Step Implementation

Method 1: Manual T-SQL Statements (Primary Method)

1. Create Table

CREATE TABLE pdf_storage (
    id INT PRIMARY KEY IDENTITY(1,1),
    pdf_name VARCHAR(255),
    pdf_data VARBINARY(MAX)
);

2. Insert PDF Data

INSERT INTO pdf_storage (pdf_name, pdf_data)
SELECT 'sample.pdf', * FROM OPENROWSET(BULK 'C:\sample.pdf', SINGLE_BLOB) AS pdf_data;

Method 2: Using DBBlobEditor (Optional Visual Tool)

DBBlobEditor integrates with SQL Server FILESTREAM for large PDF storage (>1GB), auto-creates FILESTREAM filegroups if needed, and provides real-time error prompts during PDF import.

  • FILESTREAM: Use for PDF files larger than 1 GB
