Subinterfaces of RelationalExpression in wt.query

interface

ColumnExpression This interface defines an arbitrary expression that can be used to specify a "column" in a SQL SELECT, ORDER BY, GROUP BY or WHERE clause.

Classes in wt.query that implement RelationalExpression

class	ArrayExpression This class represents an array of constants in a SQL IN clause.
class	ArrayTableExpression This class implements a TableExpression for an array of values that can be used as a table.
class	ClassAttribute This class represents a class attribute which can be used in a SQL statement.
class	ColumnListExpression This class implments a list of ColumnExpressions.
class	ConstantExpression This class represents a constant in a SQL statement.
class	DateExpression This class represents a date constant in a SQL statement.
class	FixedLengthStringExpression This class represents a fixed length string constant in a SQL statement.
class	KeywordExpression This class represents an expression that evaluates to a SQL keyword that can be used in a SQL statement.
class	RangeExpression This class represents a range in a SQL WHERE clause.
class	SQLFunction This class represents a SQL function within a SQL statement.
class	SubSelectExpression This class represents a subselect which can be used in a SQL statement.
class	TableColumn This class represents a table column which can be used in a SQL statement.

Fields in wt.query declared as RelationalExpression

private RelationalExpression	SearchCondition.leftHandSide
private RelationalExpression	SearchCondition.rightHandSide
private RelationalExpression	RangeExpression.start

Methods in wt.query that return RelationalExpression

RelationalExpression	SearchCondition.getLeftHandSide() Gets the object for the association that plays role: leftHandSide.
RelationalExpression	SearchCondition.getRightHandSide() Gets the object for the association that plays role: rightHandSide.

Methods in wt.query with parameters of type RelationalExpression

void	SQLFunction.setArgumentAt(RelationalExpression a_argument, int a_position) Deprecated. Use setArgumentAt(ColumnExpression, int)
private void	SearchCondition.initialize(Class queryClass, String attribute, String operator, RelationalExpression rhs)
private void	SearchCondition.initialize(RelationalExpression lhs, String a_operator, RelationalExpression rhs)
private void	SearchCondition.initialize(RelationalExpression lhs, String a_operator, RelationalExpression rhs, int leftIndex, int rightIndex)
private boolean	SearchCondition.checkAdvancedQuery(RelationalExpression a_expression)

Constructors in wt.query with parameters of type RelationalExpression

SQLFunction(String a_function, RelationalExpression a_arg1)
Deprecated. Use newSQLFunction(String, ColumnExpression)

SQLFunction(String a_function, RelationalExpression a_arg1, RelationalExpression a_arg2)
Deprecated. Use newSQLFunction(String, ColumnExpression, ColumnExpression)

SearchCondition(RelationalExpression a_leftHandSide, String a_operator, RelationalExpression a_rightHandSide)
Constructs a SearchCondition.

SearchCondition(RelationalExpression a_leftHandSide, String a_operator)
Constructs a SearchCondition.

SearchCondition(RelationalExpression a_leftHandSide, String a_operator, RelationalExpression a_rightHandSide, int a_leftFromIndex, int a_rightFromIndex)
Deprecated. as of R6.0, use SearchCondition(RelationalExpression, String, RelationalExpression) and setFromIndicies(int[], int)
