What are some advanced LINQ techniques for SQL queries?

Advanced LINQ techniques include using joins, grouping, and projections to optimize SQL queries. Would you like examples?

Yes, can you show me an example of a join in LINQ?

Sure! Here's a simple example: var result = from a in tableA join b in tableB on a.Id equals b.AId select new { a.Name, b.Description }; This joins two tables based on a common key.

How about using grouping in LINQ?

You can group data like this: var grouped = from item in table group item by item.Category into g select new { Category = g.Key, Count = g.Count() }; This groups items by category and counts them.

Thanks! What about projections?

Projections can be done using select to shape the data. For example: var projected = from item in table select new { item.Name, item.Price }; This selects only the Name and Price fields.
