如果主鍵爲null，則會將js upsert控件集中起來

我正嘗試使用postgresql的sequelize js的upsert方法。我生成由sequelize的自動JS如果主鍵爲null，則會將js upsert控件集中起來

我的表格模型是這樣的：

CREATE SEQUENCE TBL_CITY_LANG_SEQ; 
CREATE TABLE TBL_CITY_LANG(
    ID BIGINT DEFAULT NEXTVAL ('TBL_CITY_LANG_SEQ') NOT NULL, 
    CITY_NAME VARCHAR(150) NOT NULL, 
    CITY_ID BIGINT NOT NULL, 
    LANGUAGE_ID BIGINT NOT NULL,  
    DB_EDIT_DATE TIMESTAMP(3) NOT NULL, 
    DB_USER_ID BIGINT NOT NULL, 
    DB_STATUS_ID INT NOT NULL, 
CONSTRAINT PK_TBL_CITY_LANG_SEQ PRIMARY KEY 
(
    ID 
), 
CONSTRAINT IX_TBL_CITY_LANG_SEQ UNIQUE 
(
    LANGUAGE_ID, 
    CITY_ID 
));

而且sequelize UPSERT用法：

cityTable.upsert(myjson).then(function (result) { 
           resolve(result); 
          });

SQL執行日誌：

CREATE OR REPLACE FUNCTION pg_temp.sequelize_upsert() RETURNS integer AS $func$ 

BEGIN INSERT INTO "tbl_city_lang" ("id","city_name","city_id","language_id","db_edit_date","db_user_id","db_status_id") VALUES (1,'istanbul 1','19','1','2015-03-03','2','1'); 

RETURN 1; 

EXCEPTION WHEN unique_violation 

THEN UPDATE "tbl_city_lang" SET "id"=1,"city_name"='istanbul 1',"city_id"='19',"language_id"='1',"db_edit_date"='2015-03-03',"db_user_id"='2',"db_status_id"='1' WHERE (("id" IS NULL AND "city_id" = '19')); RETURN 2; 

END; 

$func$ LANGUAGE plpgsql; 

SELECT * FROM pg_temp.sequelize_upsert();

它不會給出錯誤，但也不會更新。我想這個問題是從腳本的where條件得出的。但該表應具有主鍵，但可以通過獨特的常量進行更新。

WHERE（（「ID」 IS NULL和「city_id」= '19'））

但該表應具有主鍵，但可更新的唯一約束。

此問題來自sequelize-auto。我編輯了源代碼。

的lib /方言/ index.js內編輯

來源：

return 'SELECT \ 
     o.conname AS constraint_name, \ 
     (SELECT nspname FROM pg_namespace WHERE oid=m.relnamespace) AS source_schema, \ 
     m.relname AS source_table, \ 
     (SELECT a.attname FROM pg_attribute a WHERE a.attrelid = m.oid AND a.attnum = o.conkey[1] AND a.attisdropped = false) AS source_column, \ 
     (SELECT nspname FROM pg_namespace WHERE oid=f.relnamespace) AS target_schema, \ 
     f.relname AS target_table, \ 
     (SELECT a.attname FROM pg_attribute a WHERE a.attrelid = f.oid AND a.attnum = o.confkey[1] AND a.attisdropped = false) AS target_column, \ 
     o.contype, \ 
     (SELECT d.adsrc AS extra FROM pg_catalog.pg_attribute a LEFT JOIN pg_catalog.pg_attrdef d ON (a.attrelid, a.attnum) = (d.adrelid, d.adnum) \ WHERE NOT a.attisdropped AND a.attnum > 0 AND a.attrelid = o.conrelid \ LIMIT 1) \ 
    FROM pg_constraint o \ 
    LEFT JOIN pg_class c ON c.oid = o.conrelid \ 
    LEFT JOIN pg_class f ON f.oid = o.confrelid \ 
    LEFT JOIN pg_class m ON m.oid = o.conrelid \ 
    WHERE o.conrelid = (SELECT oid FROM pg_class WHERE relname = \'' + tableName + '\' LIMIT 1)'

要：

：

SELECT \ 
     o.conname AS constraint_name, \ 
     (SELECT nspname FROM pg_namespace WHERE oid=m.relnamespace) AS source_schema, \ 
     m.relname AS source_table, \ 
     pga.attname AS source_column, \ 
     (SELECT nspname FROM pg_namespace WHERE oid=f.relnamespace) AS target_schema, \ 
     f.relname AS target_table, \ 
     (SELECT a.attname FROM pg_attribute a WHERE a.attrelid = f.oid AND a.attnum = o.confkey[1] AND a.attisdropped = false) AS target_column, \ 
     o.contype, \ 
     (SELECT d.adsrc AS extra FROM pg_catalog.pg_attribute a LEFT JOIN pg_catalog.pg_attrdef d ON (a.attrelid, a.attnum) = (d.adrelid, d.adnum) \ WHERE NOT a.attisdropped AND a.attnum > 0 AND a.attrelid = o.conrelid \ LIMIT 1) \ 
    FROM pg_constraint o \ 
    LEFT JOIN pg_attribute pga ON pga.attrelid = o.conindid \ 
    LEFT JOIN pg_class c ON c.oid = o.conrelid \ 
    LEFT JOIN pg_class f ON f.oid = o.confrelid \ 
    LEFT JOIN pg_class m ON m.oid = o.conrelid \ 
    WHERE o.conrelid = (SELECT oid FROM pg_class WHERE relname = \'' + tableName + '\' LIMIT 1)'

的lib/index.js

從內部編輯

else if (attr === "primaryKey") { 
      if (self.tables[table][field][attr] === true && (! _.has(self.tables[table][field], 'foreignKey') || (_.has(self.tables[table][field], 'foreignKey') && !! self.tables[table][field].foreignKey.isPrimaryKey))) 
       text[table] += spaces + spaces + spaces + "primaryKey: true"; 
      else return true 
      }

要：

else if (attr === "primaryKey") { 
      if (self.tables[table][field][attr] === true && self.tables[table][field].foreignKey.contype == 'u') 
       text[table] += spaces + spaces + spaces + "unique: '" + self.tables[table][field].foreignKey.constraint_name + "'"; 

      if (self.tables[table][field][attr] === true && (! _.has(self.tables[table][field], 'foreignKey') || (_.has(self.tables[table][field], 'foreignKey') && !! self.tables[table][field].foreignKey.isPrimaryKey))) 
       text[table] += spaces + spaces + spaces + "primaryKey: true"; 
      else return true 
      }

重新生成的模型和作品。
