Question

I have to try to convert my postgre sql query to orm concept using sequelize npm package, kindly guide me.
select * from "locationDepartmentMappings" as a
inner join "departments" as b on a."departmentId" = b.id
inner join "locations" as c on a."locationId" = c.id
where (
b."departmentName" like '%Accounting%' or c."locationName" like '%Accounting%'
)
limit 1;
As per below code still i have getting
error: column locationDepartmentMapping.department.departmentName does not exist
As #shivam mentioned i have tried depends mine below, can you what i need to changes,
let ldv = await LocationDepartmentModel.findAll({
include: [
{
model: LocationModel,
as: "location",
required: true,
},
{
model: DepartmentModel,
as: "department",
required: true,
}
],
where: {
$or: [
{
"department.departmentName": { like: `%${reqQueryName}%` }
},
{ "location.locationName": { like: `%${reqQueryName}%` } }
]
},
limit:1
});

Answer 1

Sequelize has pretty good documentation on how to write queries using the orm syntax.
To start with, the above query would look something like
Model.locationDepartmentMappings.findAll({
include: [
{
model: Model.departments
where: {departmentName: {$like: '% Accounting%'}}
},
{
model: Model.locations
where: {locationName: {$like: '% Accounting%'}}
}],
limit: 1
})
What you should consider getting to above query is
1. Learn how to create sequelize models
2. Learn Associations
3. Querying
There are a lot of great tutorials out there, which can help you get started, and are just a google search away!

Final with help got the solutions :
let ldData = await LocationDepartmentModel.findAll({
include: [
{
model: LocationModel,
as: "location",
required: true
},
{
model: DepartmentModel,
as: "department",
required: true
}
],
where: {
$or: [
{ "$department.departmentName$": { like: `%${reqQueryName}%` } },
{ "$location.locationName$": { like: `%${reqQueryName}%` } }
]
},
limit: 1
});
