使用 pg promise 将多行插入到事务中的多个表中

Question

我正在尝试使用 pg promise 执行事务，我打算在事务的多个表中插入多行。我正在使用 pg promise 辅助方法来优化插入每个表的操作，但无法将所有查询连接在一起以仅执行一个查询。如果有人能指出是否有任何方法可以进一步优化以下代码，我也将不胜感激。

目前我收到一个错误 “参数'查询'必须是一个数组。”在pgp.hlpers.concat上

db.tx(async t => {          
            let customerDataArray = [];
            let campaignStatusArray = [];
            let messageDetailsArray = [];

            for(const customer of customerDetails)
            {

                const customerData = {
                    columna1: customer.x,
                    columnb1: customer.y"
                };

                const campaignStatus = {
                    columna2: customer.a,
                    columnb2: customer.b
                };
                
                customerDataArray.push(customerData);
                campaignStatusArray.push(campaignStatus);

                for (const message of customer.messages)
                {
                    const messageStatus = {
                        columna: message.x,
                        columnb: message.y
                    };
                    messageDetailsArray.push(messageStatus);
                }
            }
            
            const customerDataCs = new pgp.helpers.ColumnSet(['columna1', 'columnb1'], {table: 'customerdata'});
            const campaignStatusCs = new pgp.helpers.ColumnSet(['columna2', 'columnb2'], {table: 'campaignstatus'});
            const messageStatusCs = new pgp.helpers.ColumnSet(['columna', 'columnb'], {table: 'messageStatus'});
            
            const customerDataQuery = pgp.helpers.insert(customerDataArray, customerDataCs);
            const campaignStatusQuery = pgp.helpers.insert(campaignStatusArray, campaignStatusCs);
            const messageStatusQuery = pgp.helpers.insert(messageDetailsArray, messageStatusCs);

            const concatAllQueries = pgp.helpers.concat(customerDataQuery, campaignStatusQuery, messageStatusQuery);

            await t.none(concatAllQueries);

        })
            .then(() => {
                // success;  
            })
            .catch(error => {
              
            });

您需要将查询传递给单个数组中的 concat，如下所示：

const concatAllQueries = pgp.helpers.concat([ customerDataQuery, campaignStatusQuery, messageStatusQuery ]);
