Class InlineQuery

java.lang.Object

org.springframework.data.relational.core.sql.Subselect

org.springframework.data.relational.core.sql.InlineQuery

All Implemented Interfaces:

Segment, TableLike, Visitable

public class InlineQuery
extends Subselect
implements TableLike

Represents an inline query within a SQL statement. Typically, used in FROM or JOIN clauses.

Renders to: (>SELECT<) AS >ALIAS< in a from or join clause, and to >ALIAS< when used in an expression.

Note that this does not implement Aliased because the Alias is not optional but required and therefore more like a name although the SQL term is "alias".

2.3

Method Details

create

public static InlineQuery create(Select select,
 SqlIdentifier alias)

Creates a new InlineQuery using an alias.

Parameters:

select - must not be null.

alias - must not be null or empty.

Returns:

the new InlineQuery using the alias.

create

public static InlineQuery create(Select select,
 String alias)

Creates a new InlineQuery using an alias.

Parameters:

select - must not be null or empty.

alias - must not be null or empty.

Returns:

the new InlineQuery using the alias.

getName

public SqlIdentifier getName()

Specified by:

getName in interface TableLike

Returns:

the table name.

getReferenceName

public SqlIdentifier getReferenceName()

Specified by:

getReferenceName in interface TableLike

Returns:

the table name as it is used in references. This can be the actual name or an alias.

visit

public void visit(Visitor visitor)

Description copied from interface: Visitable

Accept a Visitor visiting this Visitable and its nested Visitables if applicable.

Specified by:

visit in interface Visitable

Parameters:

visitor - the visitor to notify, must not be null.

hashCode

public int hashCode()

Description copied from interface: Segment

Generate a hash code from thisSegment.

Hashcode typically derives from the Segment.toString() representation so two Segments yield the same Segment.hashCode() if their Segment.toString() representation matches.

Specified by:

hashCode in interface Segment

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

equals

public boolean equals(@Nullable Object obj)

Description copied from interface: Segment

Check whether this Segment is equal to another Segment.

Equality is typically given if the Segment.toString() representation matches.

Specified by:

equals in interface Segment

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the other argument; false otherwise.
