Basic options
All repository and manager .find*
methods accept special options you can use to query data you need without using QueryBuilder
:
select
- indicates which properties of the main object must be selected
Copy userRepository .find ({
select : {
firstName : true ,
lastName : true ,
} ,
})
will execute following query:
Copy SELECT "firstName" , "lastName" FROM "user"
relations
- relations needs to be loaded with the main entity. Sub-relations can also be loaded (shorthand for join
and leftJoinAndSelect
)
Copy userRepository .find ({
relations : {
profile : true ,
photos : true ,
videos : true ,
} ,
})
userRepository .find ({
relations : {
profile : true ,
photos : true ,
videos : {
videoAttributes : true ,
} ,
} ,
})
will execute following queries:
Copy SELECT * FROM "user"
LEFT JOIN "profile" ON "profile" . "id" = "user" . "profileId"
LEFT JOIN "photos" ON "photos" . "id" = "user" . "photoId"
LEFT JOIN "videos" ON "videos" . "id" = "user" . "videoId"
SELECT * FROM "user"
LEFT JOIN "profile" ON "profile" . "id" = "user" . "profileId"
LEFT JOIN "photos" ON "photos" . "id" = "user" . "photoId"
LEFT JOIN "videos" ON "videos" . "id" = "user" . "videoId"
LEFT JOIN "video_attributes" ON "video_attributes" . "id" = "videos" . "video_attributesId"
where
- simple conditions by which entity should be queried.
Copy userRepository .find ({
where : {
firstName : "Timber" ,
lastName : "Saw" ,
} ,
})
will execute following query:
Copy SELECT * FROM "user"
WHERE "firstName" = 'Timber' AND "lastName" = 'Saw'
Querying a column from an embedded entity should be done with respect to the hierarchy in which it was defined. Example:
Copy userRepository .find ({
relations : {
project : true ,
} ,
where : {
project : {
name : "TypeORM" ,
initials : "TORM" ,
} ,
} ,
})
will execute following query:
Copy SELECT * FROM "user"
LEFT JOIN "project" ON "project" . "id" = "user" . "projectId"
WHERE "project" . "name" = 'TypeORM' AND "project" . "initials" = 'TORM'
Querying with OR operator:
Copy userRepository .find ({
where : [
{ firstName : "Timber" , lastName : "Saw" } ,
{ firstName : "Stan" , lastName : "Lee" } ,
] ,
})
will execute following query:
Copy SELECT * FROM "user" WHERE ("firstName" = 'Timber' AND "lastName" = 'Saw') OR ("firstName" = 'Stan' AND "lastName" = 'Lee')
Copy userRepository .find ({
order : {
name : "ASC" ,
id : "DESC" ,
} ,
})
will execute following query:
Copy SELECT * FROM "user"
ORDER BY "name" ASC , "id" DESC
withDeleted
- include entities which have been soft deleted with softDelete
or softRemove
, e.g. have their @DeleteDateColumn
column set. By default, soft deleted entities are not included.
Copy userRepository .find ({
withDeleted : true ,
})
find*
methods which return multiple entities (find
, findBy
, findAndCount
, findAndCountBy
) also accept following options:
skip
- offset (paginated) from where entities should be taken.
Copy userRepository .find ({
skip : 5 ,
})
Copy SELECT * FROM "user"
OFFSET 5
take
- limit (paginated) - max number of entities that should be taken.
Copy userRepository .find ({
take : 10 ,
})
will execute following query:
Copy SELECT * FROM "user"
LIMIT 10
** skip
and take
should be used together
** If you are using typeorm with MSSQL, and want to use take
or limit
, you need to use order as well or you will receive the following error: 'Invalid usage of the option NEXT in the FETCH statement.'
Copy userRepository .find ({
order : {
columnName : "ASC" ,
} ,
skip : 0 ,
take : 10 ,
})
will execute following query:
Copy SELECT * FROM "user"
ORDER BY "columnName" ASC
LIMIT 10 OFFSET 0
cache
- Enables or disables query result caching. See caching for more information and options.
Copy userRepository .find ({
cache : true ,
})
lock
- Enables locking mechanism for query. Can be used only in findOne
and findOneBy
methods. lock
is an object which can be defined as:
Copy { mode : "optimistic" , version : number | Date }
or
Copy {
mode : "pessimistic_read" |
"pessimistic_write" |
"dirty_read" |
/*
"pessimistic_partial_write" and "pessimistic_write_or_fail" are deprecated and
will be removed in a future version.
Use onLocked instead.
*/
"pessimistic_partial_write" |
"pessimistic_write_or_fail" |
"for_no_key_update" |
"for_key_share" ,
tables : string[] ,
onLocked : "nowait" | "skip_locked"
}
for example:
Copy userRepository .findOne ({
where : {
id : 1 ,
} ,
lock : { mode : "optimistic" , version : 1 } ,
})
See lock modes for more information

will execute following query:
Advanced options
TypeORM provides a lot of built-in operators that can be used to create more complex comparisons:
Copy import { Not } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
title : Not ( "About #1" ) ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "title" != 'About #1'
Copy import { LessThan } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
likes : LessThan ( 10 ) ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "likes" < 10
Copy import { LessThanOrEqual } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
likes : LessThanOrEqual ( 10 ) ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "likes" <= 10
Copy import { MoreThan } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
likes : MoreThan ( 10 ) ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "likes" > 10
Copy import { MoreThanOrEqual } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
likes : MoreThanOrEqual ( 10 ) ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "likes" >= 10
Copy import { Equal } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
title : Equal ( "About #2" ) ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "title" = 'About #2'
Copy import { Like } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
title : Like ( "%out #%" ) ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "title" LIKE '%out #%'
Copy import { ILike } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
title : ILike ( "%out #%" ) ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "title" ILIKE '%out #%'
Copy import { Between } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
likes : Between ( 1 , 10 ) ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "likes" BETWEEN 1 AND 10
Copy import { In } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
title : In ([ "About #2" , "About #3" ]) ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "title" IN ( 'About #2' , 'About #3' )
Copy import { Any } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
title : Any ([ "About #2" , "About #3" ]) ,
})
will execute following query (Postgres notation):
Copy SELECT * FROM "post" WHERE "title" = ANY(['About #2','About #3'])
Copy import { IsNull } from "typeorm"
const loadedPosts = await dataSource .getRepository (Post) .findBy ({
title : IsNull () ,
})
will execute following query:
Copy SELECT * FROM "post" WHERE "title" IS NULL
Copy import { ArrayContains } from "typeorm"
const loadedPosts = await dataSource.getRepository(Post).findBy({
categories: ArrayContains(["TypeScript"]),
})
will execute following query:
Copy SELECT * FROM "post" WHERE "categories" @> '{TypeScript}'
Copy import { ArrayContainedBy } from "typeorm"
const loadedPosts = await dataSource.getRepository(Post).findBy({
categories: ArrayContainedBy(["TypeScript"]),
})
will execute following query:
Copy SELECT * FROM "post" WHERE "categories" <@ '{TypeScript}'
Copy import { ArrayOverlap } from "typeorm"
const loadedPosts = await dataSource.getRepository(Post).findBy({
categories: ArrayOverlap(["TypeScript"]),
})
will execute following query:
Copy SELECT * FROM "post" WHERE "categories" && '{TypeScript}'
Copy import { Raw } from "typeorm"
const loadedPosts = await dataSource.getRepository(Post).findBy({
likes: Raw("dislikes - 4"),
})
will execute following query:
Copy SELECT * FROM "post" WHERE "likes" = "dislikes" - 4
In the simplest case, a raw query is inserted immediately after the equal symbol. But you can also completely rewrite the comparison logic using the function.
Copy import { Raw } from "typeorm"
const loadedPosts = await dataSource.getRepository(Post).findBy({
currentDate: Raw((alias) => `${alias} > NOW()`),
})
will execute following query:
Copy SELECT * FROM "post" WHERE "currentDate" > NOW()
If you need to provide user input, you should not include the user input directly in your query as this may create a SQL injection vulnerability. Instead, you can use the second argument of the Raw
function to provide a list of parameters to bind to the query.
Copy import { Raw } from "typeorm"
const loadedPosts = await dataSource.getRepository(Post).findBy({
currentDate: Raw((alias) => `${alias} > :date`, { date: "2020-10-06" }),
})
will execute following query:
Copy SELECT * FROM "post" WHERE "currentDate" > '2020-10-06'
If you need to provide user input that is an array, you can bind them as a list of values in the SQL statement by using the special expression syntax:
Copy import { Raw } from "typeorm"
const loadedPosts = await dataSource.getRepository(Post).findby({
title: Raw((alias) => `${alias} IN (:...titles)`, {
titles: [
"Go To Statement Considered Harmful",
"Structured Programming",
],
}),
})
will execute following query:
Copy SELECT * FROM "post" WHERE "titles" IN ('Go To Statement Considered Harmful', 'Structured Programming')
Combining Advanced Options
Also you can combine these operators with below:
Copy import { Not, MoreThan, Equal } from "typeorm"
const loadedPosts = await dataSource.getRepository(Post).findBy({
likes: Not(MoreThan(10)),
title: Not(Equal("About #2")),
})
will execute following query:
Copy SELECT * FROM "post" WHERE NOT("likes" > 10) AND NOT("title" = 'About #2')
Copy import { Not, MoreThan, ILike } from "typeorm"
const loadedPosts = await dataSource.getRepository(Post).findBy({
title: Or(Equal("About #2"), ILike("About%")),
})
will execute following query:
Copy SELECT * FROM "post" WHERE "title" = 'About #2' OR "title" ILIKE 'About%'
Copy import { And, Not, Equal, ILike } from "typeorm"
const loadedPosts = await dataSource.getRepository(Post).findBy({
title: And(Not(Equal("About #2")), ILike("%About%")),
})
will execute following query:
Copy SELECT * FROM "post" WHERE NOT("title" = 'About #2') AND "title" ILIKE '%About%'
