Question

我该如何处理该错误？

ERROR:  too many column names were specified

我不知道要进行这项工作我需要更改什么。我的CREATE语句中是否确实有太多列，还是AS SELECT中的这列出错了？

CREATE TABLE planification_finale_asset2_test
(   nom,
nom_court,
serveur,
scheduled_backup,
schedule,
retention,
groupe,
remote_access,
alias,
parallelisme,
storage_nodes,

SELECT t1.*, CONCAT(groupe, ' status ', scheduled_backup) AS etat_groupe,
    CONCAT(groupe, ' status ', groupe_actif) AS etat_groupe_actif,
    t3.volume_sauvegarde, t3.volume_externalise, t3.volume_replique
from planification_client_biens_group_test t1
LEFT OUTER JOIN volumetrie_1_jour t3
    ON t1.nom LIKE CONCAT(t3.client, '%') AND
       t1.serveur = t3.serveur_court;

感谢您的帮助！

Answer 1

请尝试以下查询

SELECT t1.*, CONCAT(groupe, ' status ', scheduled_backup) AS etat_groupe,
    CONCAT(groupe, ' status ', groupe_actif) AS etat_groupe_actif,
    t3.volume_sauvegarde, t3.volume_externalise, t3.volume_replique
into planification_finale_asset2_test from planification_client_biens_group_test t1
LEFT OUTER JOIN volumetrie_1_jour t3
    ON t1.nom LIKE CONCAT(t3.client, '%') AND
       t1.serveur = t3.serveur_court;

它将把数据加载到表planification_finale_asset2_test中。

指定了太多的列名
