READ_UNCOMMITTED in SQL Server

📑 Understanding READ_UNCOMMITTED in SQL Server
READ_UNCOMMITTED is the lowest isolation level in SQL Server. When a query runs with this isolation level:

🟢 Benefits:

• Fastest reading performance
• No locks on data
• Never waits for locks to be released

🔴 Risks:

• Dirty Read: May read uncommitted data
• Non-Repeatable Read: Reading the same record twice might give different results

❓When to use:

• Non-critical reporting
• Displaying approximate stats and metrics
• Where eventual consistency is acceptable
• Reading low-importance data where 100% accuracy isn't required

❓When NOT to use:

• Financial transactions
• Critical calculations
• Where data consistency is crucial
• Interdependent operations

using(var transaction = connection.BeginTransaction(IsolationLevel.ReadUncommitted))
{
// Read Data
}
