There are 2 ways to call this method:

Example​

Java code:

k
.select(
    APP_USER.EMAIL.ascii().chr()
)
.from(APP_USER)
.multiple();

SQL generated:

SELECT
    CHR(ASCII(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:

  • chr(KColumn kColumn): Receives a KColumn or a KTableColumn which will be supplied to the CHR function.

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

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

Java code:

k
.select(
    chr(ascii(APP_USER.EMAIL))
)
.from(APP_USER)
.multiple();

SELECT
    CHR(ASCII(au.email))
FROM app_user au
