Constructors

InExpression(SqlExpression, Boolean, SelectExpression, RelationalTypeMapping)	Obsolete. Creates a new instance of the InExpression class which represents a `item` IN subquery expression.
InExpression(SqlExpression, Boolean, SqlExpression, RelationalTypeMapping)	Obsolete. Creates a new instance of the InExpression class which represents a `item` IN values expression.
InExpression(SqlExpression, IReadOnlyList<SqlExpression>, RelationalTypeMapping)	Creates a new instance of the InExpression class, representing a SQL `IN` expression with a given list of values.
InExpression(SqlExpression, SelectExpression, Boolean, RelationalTypeMapping)	Creates a new instance of the InExpression class which represents a `item` IN subquery expression.
InExpression(SqlExpression, SelectExpression, RelationalTypeMapping)	Creates a new instance of the InExpression class, representing a SQL `IN` expression with a subquery.
InExpression(SqlExpression, SqlExpression, Boolean, RelationalTypeMapping)	Creates a new instance of the InExpression class which represents a `item` IN values expression.
InExpression(SqlExpression, SqlParameterExpression, RelationalTypeMapping)	Creates a new instance of the InExpression class, representing a SQL `IN` expression with a given parameterized list of values.

Properties

IsNegated	The value indicating if item should be present in the values or absent.
Item	The item to look into values.
NodeType	(Inherited from SqlExpression)
Subquery	The subquery to search the item in.
Type	(Inherited from SqlExpression)
TypeMapping	The RelationalTypeMapping associated with this expression. (Inherited from SqlExpression)
Values	The list of values to search the item in.
ValuesParameter	A parameter containing the list of values to search the item in. The parameterized list get expanded to the actual value before the query SQL is generated.

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
Negate()	Negates this expression by changing presence/absence state indicated by IsNegated.
Print(ExpressionPrinter)	Creates a printable string representation of the given expression using ExpressionPrinter.
Quote()	System.Linq.Expressions.Expression.Quote
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. (Inherited from SqlExpression)
Update(SqlExpression, IReadOnlyList<SqlExpression>)	Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.
Update(SqlExpression, SelectExpression, IReadOnlyList<SqlExpression>, SqlParameterExpression)	Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.
Update(SqlExpression, SelectExpression)	Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.
Update(SqlExpression, SqlExpression, SelectExpression)	Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.
Update(SqlExpression, SqlParameterExpression)	Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.
VisitChildren(ExpressionVisitor)	Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible.
