Interface CaseWhenStep<V,T>

Type Parameters:

V - The type of values being compared in this case statement

T - The type returned by this case statement

All Superinterfaces:

Field<T>, FieldOrConstraint, FieldOrRow, GroupField, Named, OrderField<T>, QueryPart, SelectField<T>, SelectFieldOrAsterisk, Serializable, Typed<T>

public interface CaseWhenStep<V,T>
extends Field<T>

The final step in creating a case statement of the type

 CASE x WHEN 1 THEN 'one'

Method Details

when

@NotNull
@Support
@NotNull CaseWhenStep<V,T> when(V compareValue,
 T result)

Compare a value to the already constructed case statement, return result if values are equal.

Parameters:

compareValue - The value to compare with the already constructed case statement

result - The result value if values are equal

Returns:

An intermediary step for case statement construction

when

@NotNull
@Support
@NotNull CaseWhenStep<V,T> when(V compareValue,
 Field<T> result)

Compare a value to the already constructed case statement, return result if values are equal.

Parameters:

compareValue - The value to compare with the already constructed case statement

result - The result value if values are equal

Returns:

An intermediary step for case statement construction

when

@NotNull
@Support
@NotNull CaseWhenStep<V,T> when(Field<V> compareValue,
 T result)

Compare a value to the already constructed case statement, return result if values are equal.

Parameters:

compareValue - The value to compare with the already constructed case statement

result - The result value if values are equal

Returns:

An intermediary step for case statement construction

when

@NotNull
@Support
@NotNull CaseWhenStep<V,T> when(Field<V> compareValue,
 Field<T> result)

Compare a value to the already constructed case statement, return result if values are equal.

Parameters:

compareValue - The value to compare with the already constructed case statement

result - The result value if values are equal

Returns:

An intermediary step for case statement construction

mapValues

@NotNull
@Support
@NotNull CaseWhenStep<V,T> mapValues(Map<V,T> values)

Create WHEN .. THEN expressions from a Map.

This will iterate over the map's entries to create individual WHEN .. THEN expressions for each map entry.

mapFields

@NotNull
@Support
@NotNull CaseWhenStep<V,T> mapFields(Map<? extends Field<V>,? extends Field<T>> fields)

Create WHEN .. THEN expressions from a Map.

This will iterate over the map's entries to create individual WHEN .. THEN expressions for each map entry.

otherwise

@NotNull
@Support
@NotNull Field<T> otherwise(T result)

Add an else clause to the already constructed case statement

Parameters:

result - The result value if no other value matches the case

Returns:

The resulting field from case statement construction

otherwise

@NotNull
@Support
@NotNull Field<T> otherwise(Field<T> result)

Add an else clause to the already constructed case statement

Parameters:

result - The result value if no other value matches the case

Returns:

The resulting field from case statement construction

else_

@NotNull
@Support
@NotNull Field<T> else_(T result)

Add an else clause to the already constructed case statement

Parameters:

result - The result value if no other value matches the case

Returns:

The resulting field from case statement construction

else_

@NotNull
@Support
@NotNull Field<T> else_(Field<T> result)

Add an else clause to the already constructed case statement

Parameters:

result - The result value if no other value matches the case

Returns:

The resulting field from case statement construction
