我在中创建了一个表 clickhouse 如下所示：

let clickhouse = new ClickHouse (sails.config.clickhouse);
let query = `CREATE TABLE table1(category String,subcategory String,title String,id Int64) Engine=Log`

我试着运行上面的查询：

return new Promise((resolve, reject) => {
            clickhouse.query (query, function (err, result) {
                if (err) {
                    console.log(err);
                }
                resolve('success');
            });
        });
let test = await createTable();

但后来我犯了一个错误：
无法读取未定义的属性'omitformat'
这个错误有什么解决办法吗？谢谢
p、 s:我试过在中运行查询 Clickhouse 客户和它的工作。

传递未初始化的sails.config.clickhouse-param。
将未定义的选项传递给clickhouse构造函数会导致此行出错。
查看控制台以查看相关警告：

再现这个错误的代码（参见https://repl.it/repls/fakeportlyexponent):

const ClickHouse = require('@apla/clickhouse')

let clickhouse = new ClickHouse (/*sails.config.clickhouse*/null); // <----- !!!
let query = `CREATE TABLE table1(category String,subcategory String,title String,id Int64) Engine=Log`;

async function createTable() {
  return new Promise((resolve, reject) => {
              clickhouse.query (query, function (err, result) {
                  if (err) {
                      console.log(err);
                  }
                  resolve('success');
              });
          });
}

createTable()
    .then(() => {
        console.info('Success.');
    })
    .catch(err => {
        console.error('Error:', err);
    });
