Bit Length

Definition​

The bitLength method allows you to add the BIT_LENGTH function to the query. The BIT_LENGTH function is used to count the number of bits in a specified string.

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:

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

Example​

Java code:

k
.select(
    APP_USER.EMAIL.bitLength()
)
.from(APP_USER)
.multiple();

SQL generated:

SELECT
    BIT_LENGTH(au.email)
FROM app_user au

Parameters:

  • None

2. Calling from the KFunction class​

The only one method available to use this functionality calling from the KFunction class is:

  • bitLength(KColumn kColumn): Receives a KColumn or a KTableColumn which will be supplied to the BIT_LENGTH 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(
    bitLength(APP_USER.EMAIL)
)
.from(APP_USER)
.multiple();

SQL generated:

SELECT
    BIT_LENGTH(au.email)
FROM app_user au

Parameters:

  • None
