sql - solucion - STRAGG en Oracle Database 11g Enterprise Edition versión 11.2.0.4.0-Producción de 64 bits

ora 01034 oracle not available solucion

Question

Quiero usar la función STRAGG en este entorno: Oracle Database 11g Enterprise Edition Versión 11.2.0.4.0 - Producción de 64 bits, Versión PL / SQL 11.2.0.4.0 - Producción, Producción CORE 11.2.0.4.0, TNS para Linux: Versión 11.2.0.4.0 - Producción, NLSRTL Versión 11.2.0.4.0 - Producción:

Tengo una vista llamada V_USER_ROLE_DESC

LOGIN DESC
joanet BS in ANDROID.C.3
joanet DOB in ANDROID.C.3
joanet DO in ANDROID.C.3
joanet BS in ANDROID.C.4
joanet UA in ANDROID.C.4
joanet OV in ANDROID.C.4
joanet OI in ANDROID.C.4
joanet DO in ANDROID.C.4
joanet DHoU in ANDROID.C.4
joanet AOP in ANDROID.C.4

Ejecutar esta consulta

select
login ,
sys.STRAGG( UNIT_ROLE_DESC || '' - '' ) as string
from
V_USER_ROLE_DESC
where login = ''joanet''
group by
login
;

Este es el resultado:

joanet BS in ANDROID.C.3 - DOB in ANDROID.C.3 - DO in ANDROID.C.3 - BS in ANDROID.C.4 - UA in ANDROID.C.4 - OV in ANDROID.C.4 - OI in ANDROID.C.4 - DO in ANDROID.C.4 - DHoU in ANDROID.C.4 - AOP in ANDROID.C.4 - 

Pero sin la cláusula where ...

 select
login ,
sys.STRAGG( UNIT_ROLE_DESC || '' - '' ) as string
from
V_USER_ROLE_DESC
--where login = ''joanet''
group by
login
;

este es el resultado:

...
colau DOB in ANDROID.D.2 -
joanet DOB in ANDROID.D.2 -
sisa DOB in ANDROID.D.2 -
...

Utilizando

SELECT login ,listagg(unit_role_desc,'' - '') WITHIN GROUP (ORDER BY unit_role_desc) AS STRING FROM v_user_role_desc WHERE 1=1 GROUP BY LOGIN;

Tengo este error

ORA-01489: el resultado de la concatenación de cadenas es demasiado largo

Answer 1

Sugiero usar LISTAGG en lugar de STRAGG. LISTAGG es superior porque permite especificar el orden de los elementos agregados.

SELECT login
,listagg(unit_role_desc,'' - '') WITHIN GROUP (ORDER BY unit_role_desc) AS STRING
FROM v_user_role_desc
WHERE 1=1
-- AND login = ''joanet''
GROUP BY LOGIN;
