Use the Cot
function to return the cotangent of the specified expression.
Syntax
db.fx.Cot({expression})
Arguments
- expression
- – The value to use in the cotangent calculation.
Returns
float
Examples
Select Statement
Select the cotangent of a product's weight (which is nullable in the database).
float? result = db.SelectOne(
db.fx.Cot(dbo.Product.Weight)
)
.From(dbo.Product)
.Execute();
Where Clause
Select the cotangent of a product's depth (which is nullable in the database).
float? result = db.SelectOne(
db.fx.Cot(dbo.Product.Depth)
)
.From(dbo.Product)
.Execute();
Order By Clause
Select and order by the cotangent of a product's depth.
IEnumerable<Product> result = db.SelectMany<Product>()
.From(dbo.Product)
.OrderBy(db.fx.Cot(dbo.Product.Depth).Desc())
.Execute();
Group By Clause
Select product details grouped by product category and the cotangent of the product's depth.
IEnumerable<dynamic> results = db.SelectMany(
dbo.Product.ProductCategoryType,
db.fx.Cot(dbo.Product.Depth).As("calculated_value")
)
.From(dbo.Product)
.GroupBy(
dbo.Product.ProductCategoryType,
db.fx.Cot(dbo.Product.Depth)
)
.Execute();
Having Clause
Select the ids of all products, grouped by product category type having a cotangent of the product's height greater than the product's width.
IEnumerable<ProductCategoryType?> results = db.SelectMany(
dbo.Product.ProductCategoryType
)
.From(dbo.Product)
.GroupBy(
dbo.Product.ProductCategoryType,
db.fx.Cot(dbo.Product.Height),
dbo.Product.Width
)
.Having(
db.fx.Cot(dbo.Product.Height) > dbo.Product.Width
)
.Execute();
