public interface QueryPart
extends java.io.Serializable

The common base type for all objects that can be used for query composition.

All QueryPart implementations can be cast to QueryPartInternal in order to access the internal API.

Method Summary

Modifier and Type	Method and Description
boolean	equals(java.lang.Object object) Check whether this QueryPart can be considered equal to another QueryPart.
int	hashCode() Generate a hash code from this QueryPart.
java.lang.String	toString() Render a SQL string representation of this QueryPart.

Method Detail

toString

java.lang.String toString()

Render a SQL string representation of this QueryPart.

For improved debugging, this renders a SQL string of this QueryPart with inlined bind variables. If this QueryPart is Attachable, then the attached Configuration may be used for rendering the SQL string, including SQLDialect and Settings. Do note that most QueryPart instances are not attached to a Configuration, and thus there is no guarantee that the SQL string will make sense in the context of a specific database.

If you wish to gain more control over the concrete SQL rendering of this QueryPart, use DSLContext.renderContext() to obtain a configurable render context for SQL rendering.

Overrides:

toString in class java.lang.Object

Returns:

A SQL string representation of this QueryPart

equals

boolean equals(java.lang.Object object)

Check whether this QueryPart can be considered equal to another QueryPart.

In general, QueryPart equality is defined in terms of toString() equality. In other words, two query parts are considered equal if their rendered SQL (with inlined bind variables) is equal. This means that the two query parts do not necessarily have to be of the same type.

Some QueryPart implementations may choose to override this behaviour for improved performance, as toString() is an expensive operation, if called many times.

Overrides:

equals in class java.lang.Object

Parameters:

object - The other QueryPart

Returns:

Whether the two query parts are equal

hashCode

int hashCode()

Generate a hash code from this QueryPart.

In general, QueryPart hash codes are the same as the hash codes generated from toString(). This guarantees consistent behaviour with equals(Object)

Some QueryPart implementations may choose to override this behaviour for improved performance, as toString() is an expensive operation, if called many times.

Overrides:

hashCode in class java.lang.Object

Returns:

The QueryPart hash code
