Every

Definition​

The every method allows you to add the EVERY function to the query. The EVERY is a function that returns the “logical AND” of all specified non-null boolean input values. That is, this function returns true if all non-null input values ​​are true, and otherwise returns false (Equivalent to BOOL_AND).

There are 2 ways to call this method:

1. Calling from a KColumn or a KTableColumn​

The only one method available to use this functionality calling from a KColumn or a KTableColumn is:

  • every(): It does not receive any parameters. The KColumn or KTableColumn that invokes the method will be the one supplied to the EVERY function.

Example​

Java code:

k
.select(
    APP_USER.ID.every(),
    APP_USER.CREATED_AT.cast(date())
)
.from(APP_USER)
.groupBy(APP_USER.CREATED_AT.cast(date()))
.multiple();

SQL generated:

SELECT
    EVERY(au.id),
    CAST(au.created_at AS DATE)
FROM app_user au
GROUP BY CAST(au.created_at AS DATE)

Parameters:

  • None

2. Calling from the KFunction class​

The methods available to use this functionality calling from the KFunction class are:

  • every(KColumn kColumn): Receives a KColumn or a KTableColumn which will be supplied to the EVERY function.
  • every(KCondition kCondition): Receives a KCondition which will be supplied to the EVERY function.

To use this way, you need to import the static functions as follows:

import static com.myzlab.k.KFunction.*;

Example​

Java code:

k
.select(
    every(APP_USER.ID),
    APP_USER.CREATED_AT.cast(date())
)
.from(APP_USER)
.groupBy(APP_USER.CREATED_AT.cast(date()))
.multiple();

SQL generated:

SELECT
    EVERY(au.id),
    CAST(au.created_at AS DATE)
FROM app_user au
GROUP BY CAST(au.created_at AS DATE)

Parameters:

  • None
