指定的列名太多

Question

我该如何处理这个错误？

ERROR:  too many column names were specified

我不知道我必须改变什么才能使这项工作。我的 CREATE 语句中的列真的太多了，还是 AS SELECT 中的这个出错了？

CREATE TABLE planification_finale_asset2_test
(   nom,
nom_court,

scheduled_backup,
schedule,

groupe,
remote_access,

parallelisme,

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;

它会将数据加载到您的 table planification_finale_asset2_test。
