使用 AND 和 OR 子句续集构建动态 where 子句条件

Question

我正在尝试构建一个具有 AND 和 OR 子句的动态续集 where 子句条件。

const objArr = [{ active: 'true' }];
      for (let i = 0; i < dynamicList.length; i++) {
        objArr.push({
          [Op.or]: [{ hierarchy: { [Op.like]: `%${dynamicList[i]}%` } }, { id: dynamicList[i] }],
        });
      }
      const condition = {
        where: {
          [Op.and]: objArr,
        },
        attributes: [Sequelize.fn('DISTINCT', Sequelize.col('name'))],
      };
      db.tableName
        .findAll(condition)
        .then((resul) => {
          callback(null, result);
        })
        .catch((err) => {
          callback(err, null);
        });

SQL 已生成查询

SELECT DISTINCT(name)
FROM tableName AS tableName 
WHERE (tableName.active = 'true' AND
 (tableName.hierarchy LIKE '%111%' OR tableName.id = '111') AND
 (tableName.hierarchy LIKE '%222%' OR tableName.id = '222'));

SQL 预期查询 --> active=true AND ((dynamic_list) OR (dynamic_list))

SELECT DISTINCT(name)
FROM tableName AS tableName 
WHERE (tableName.active = 'true' AND
 (tableName.hierarchy LIKE '%111%' OR tableName.id = '111') OR
 (tableName.hierarchy LIKE '%222%' OR tableName.id = '222'));

您需要将所有动态条件组合成一个上层 Op.or，然后才将此 Op.or 添加到 Op.and 的数组中：

const objArr = [{ active: 'true' }];
const dynamicConditions = [];
      for (let i = 0; i < dynamicList.length; i++) {
        dynamicConditions.push({
          [Op.or]: [{ hierarchy: { [Op.like]: `%${dynamicList[i]}%` } }, { id: dynamicList[i] }],
        });
      }
      if (dynamicConditions.length) {
        objArr.push({
          [Op.or]: dynamicConditions
        });
      }
      const condition = {
        where: {
          [Op.and]: objArr,
        },
        attributes: [Sequelize.fn('DISTINCT', Sequelize.col('name'))],
      };

使用 AND 和 OR 子句续集构建动态 where 子句条件

Sequelize build dynamic where clause condition with AND and OR clause
