Remarks

This is a simple wrapper around a ParameterExpression in the SQL tree. Instances of this type cannot be constructed by application or database provider code. If this is a problem for your application or provider, then please file an issue at github.com/dotnet/efcore.

Constructors

SqlParameterExpression(String, Type, Boolean, RelationalTypeMapping)	Creates a new instance of the SqlParameterExpression class.
SqlParameterExpression(String, Type, RelationalTypeMapping)	Creates a new instance of the SqlParameterExpression class.

Properties

IsNullable	The bool value indicating if this parameter can have null values.
Name	The name of the parameter.
NodeType	(Inherited from SqlExpression)
Type	(Inherited from SqlExpression)
TypeMapping	The RelationalTypeMapping associated with this expression. (Inherited from SqlExpression)

Methods

ApplyTypeMapping(RelationalTypeMapping)	Applies supplied type mapping to this expression.
Equals(Object)	System.Linq.Expressions.Expression.Equals(System.Object)
GetHashCode()	System.Linq.Expressions.Expression.GetHashCode
Print(ExpressionPrinter)	Creates a printable string representation of the given expression using ExpressionPrinter.
Print(ExpressionPrinter)	Creates a printable string representation of the given expression using ExpressionPrinter. (Inherited from SqlExpression)
Quote()	Quotes the expression; that is, returns an expression that, when evaluated, would construct an expression identical to this one. Used to generate code for precompiled queries, which reconstructs this expression.
