# typeorm entity proxy for save
use `repository.save(entity)` with 1 UPDATE query
## repository.save()
```ts
async function fn_save(conn: Connection, user: UserEntity) {
const repo = conn.manager.getRepository(UserEntity);
user.data = 'save';
await repo.save(user, { transaction: false });
}
```
query
```
query: SELECT "UserEntity"."key1" AS "UserEntity_key1", "UserEntity"."key2" AS "UserEntity_key2", "UserEntity"."data" AS "UserEntity_data" FROM "user_entity" "UserEntity" WHERE "UserEntity"."key1" = ? AND "UserEntity"."key2" = ? -- PARAMETERS: ["foo","bar"]
query: UPDATE "user_entity" SET "data" = ? WHERE "key1" = ? AND "key2" = ? -- PARAMETERS: ["save","foo","bar"]
```
* pros: simple
* cons: 1 SELECT + 1 UPDATE

const user = EntityProxy.create(ent);
user.data = 'custom';
await repo.customSave(user);
