Question

我想将这种类型的请求与sequelize一起使用，以在一个请求中进行大量更新（出于性能原因）：

UPDATE employee
SET address = new.address,
name = new.name
from (values :updateStack) AS new(address, name, employeeId)
WHERE employee.id = new.employeeId

这里是updateStack的值：

[{
    address: 'France',
    name: 'Chris',
    employeeId: 21
}, {
    address: 'UK',
    name: 'Steve',
    employeeId: 42
}]

我不确定续集如何正确解析updateStack数组。有什么想法吗？

此SQL查询工作正常：

UPDATE employee
SET address = new.address,
name = new.name
from (values ('France', 'Chris', 21), ('UK', 'Steve', 42)) AS new(address, name, employeeId)
WHERE employee.id = new.employeeId

谢谢，祝你有美好的一天。

我发现了如何做！

sequelize.query(
            `
                UPDATE employee
                SET address = new.address,
                name = new.name
                from (values ?) AS new(address, name, employeeId)
                WHERE employee.id = new.employeeId
            `,
            {
                replacements: [['France', 'Chris', 21], ['UK', 'Steve', 42]],
                type: models.models.sequelize.QueryTypes.INSERT
            }
    )

在Sequelize中使用原始批量更新查询
