All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`SubqueryBuilder<T>`	`from(Class<?> entityClass)` Like `from(java.lang.Class, java.lang.String)` with the alias equivalent to the camel cased result of what `Class.getSimpleName()` of the entity class returns.
`SubqueryBuilder<T>`	`from(Class<?> entityClass, String alias)` Creates a new subquery builder with the given entity class as entity in the FROM clause with the given alias.
`SubqueryBuilder<T>`	`from(String correlationPath)` Like `from(String, String)` with the alias equivalent to the camel cased result of the class of the correlation parent.
`SubqueryBuilder<T>`	`from(String correlationPath, String alias)` Creates a new subquery builder with the given correlation path in the FROM clause with the given alias.
`SubqueryBuilder<T>`	`fromIdentifiableValues(Class<?> valueClass, String alias, int valueCount)` Creates a new subquery builder with a VALUES clause for values of the given value class in the from clause.
`<X> SubqueryBuilder<T>`	`fromIdentifiableValues(Class<X> valueClass, String alias, Collection<X> values)` Like `fromIdentifiableValues(Class, String, int)` but passes the collection size as valueCount and directly binds the collection as parameter via `ParameterHolder.setParameter(String, Object)`.
`SubqueryBuilder<T>`	`fromNew(Class<?> entityClass)` Like `from(Class)` but explicitly queries the data after any side effects happen because of CTEs.

`SubqueryBuilder<T>`	`fromOld(Class<?> entityClass)` Like `from(Class)` but explicitly queries the data before any side effects happen because of CTEs.
`SubqueryBuilder<T>`	`fromOld(Class<?> entityClass, String alias)` Like `from(Class, String)` but explicitly queries the data before any side effects happen because of CTEs.

    Parameters:
    
    valueClass - The class of the basic or managed type for which to create a VALUES clause
    
    alias - The alias for the entity
    
    valueCount - The number of values to use for the values clause

```
    Creates a new subquery builder with a VALUES clause for values of the given value class in the from clause. This introduces a parameter named like the given alias. In contrast to fromValues(Class, String, int) this will only bind the id attribute.
