Overview

Welcome to Exposed, an ORM framework for Kotlin. Exposed offers two levels of database access: typesafe SQL wrapping DSL and lightweight data access objects. Our official mascot is Cuttlefish, which is best known for its outstanding mimicry abilities letting it blend seamlessly in any environment. Just like our mascot, Exposed can mimic a variety of database engines and help you build database applications without hard dependencies on any specific database engine, and switch between them with very little or no changes in your code.

Supported Databases

H2
MySQL
MariaDB
Oracle
PostgreSQL
PostgreSQL using the pgjdbc-ng JDBC driver
SQL Server
SQLite

Examples

Leaking conection with hikari and postgres

Using: exposed 0.12.1, PG 42.2.5, hikari 3.2.0

The way I run transaction:

private fun <T> runWithinTransaction(db: Database, block: () -> T): T {
        return transaction(db) {
            addLogger(Slf4jSqlDebugLogger)
            warnLongQueriesDuration = 2000
            connection.prepareStatement("SET LOCAL statement_timeout TO 1").use {
                it.execute()
            }
            block()
        }
    }

I've set it to 1ms by design in test, so I can achieve in shorter time same what happen on prod with longer timeouts.

Any suggestion what may cause it?

Additionally, is there any other way to set query timeout ?

Multiple databases

Can I use multiple connection? Can I use something like this?

val db1 = Database.connect("jdbc:h2:dbfile1", "org.h2.Driver")
val db2 = Database.connect("jdbc:h2:dbfile2", "org.h2.Driver")

db1.transaction {
    // working with the first database
}

db2.transaction {
    // working with the second database
}

I have read the source and if I understand I can use separate bases in separate threads. Like this.

// thread 1
Database.connect("jdbc:h2:dbfile1", "org.h2.Driver")
transaction { // first db }

// thread 2
Database.connect("jdbc:h2:dbfile2", "org.h2.Driver")
transaction { // second db }

That's right?

Name for primary key constraint
At the moment there seems to be no way to set a constraint name for primary key:

object TestTable : IdTable<Long>("test") { override val id = long("id") .primaryKey() // <- cant set the name .autoIncrement("test_table_id_seq") .entityId() }

Exposed seems to always generate it automatically using this pattern:

pk_$tableName

I would like to have the ability to use a different naming pattern as I'm following this naming convention.

In-memory Sqlite DB disappears between transactions

I have an in-memory sqlite db. The following code yields an error. Here's the code:

object Person : Table("person") {
    val id = integer("id").autoIncrement().primaryKey()

    val dateOfBirth = date("dateOfBirth")

Person.insert {

Support explicit transaction manager

ExplicitTransactionManager (as opposed to ThreadLocalTransactionManager) will allow supporting features that require switching threads inside a transaction. Examples of that are coroutines and thread pools usage inside a transaction.

I think that in order to be able to do that TransactionManager companion object references should be replaced in statements and queries. I can try to do a priliminary pull request to make the suggestion more clear if that sounds like an approach we would like to take. I guess it might change some interfaces/method signaures.

support for native sql?
Exposed looks great! Yet at some point I fear that some complex queries will not be representable by Kotlin magic. And, frankly,

(Users innerJoin Cities).slice(Users.name, Cities.name). select {(Users.id.eq("andrey") or Users.name.eq("Sergey")) and Users.id.eq("sergey") and Users.cityId.eq(Cities.id)}.forEach { println("${it[Users.name]} lives in ${it[Cities.name]}") }

Is too high-level magic for my tired brain :-)

I would prefer something like this for complex queries (you know one of those queries hand-tuned for perfection, which runs only 5 hours instead of 10 weeks):

"select u.name, c.name from user u inner join city c where blah blah".map(Users.name, Cities.name).forEach { ... }

Anyway, thanks for a fresh wind in the stale waters of JPA ;) It's good to have a framework where I can represent tables with objects, but without the 1st level cache/LazyInitializationException/other goodies from the JPA world. Yet, I want to be in charge of creating/migrating tables (of the DDL), and of queries more complex than "gimme all users in this city".

Exposed slow
I'm trying to connect to the H2 database on an embedded device.

The connection using

Database.connect("jdbc:h2:~/testdb;DB_CLOSE_DELAY=-1", driver = "org.h2.Driver", user = "root", password = "")

takes about 7s to create/open a database, but the connection using another library, for example kotliquery

val create = measureTimeMillis { sess = sessionOf("jdbc:h2:~/testdb;DB_CLOSE_DELAY=-1", "root", "") sess.execute(queryOf("CREATE TABLE IF NOT EXISTS RandomText(ID INT PRIMARY KEY auto_increment, text VARCHAR(15));")) }

takes about 2s.

Any reason for that overhead and is there any way to speed it up?

We're running the program and the database on an embedded device called Colibri IMx6, and the speedup would greatly help us.

MySQL table names case sensitivity

MySQL documentation https://dev.mysql.com/doc/refman/5.7/en/identifier-case-sensitivity.html says about system variable lower_case_table_names value 2:

Table and database names are stored on disk using the lettercase specified in the CREATE TABLE or CREATE DATABASE statement, but MySQL converts them to lowercase on lookup. Name comparisons are not case sensitive. This works only on file systems that are not case sensitive! InnoDB table names are stored in lowercase, as for lower_case_table_names=1.

And this is exactly what I see on my Mac when I run tests. First of all, org.jetbrains.exposed.sql.tests.shared.DDLTests#testCreateMissingTablesAndColumns01 creates table Busy and MySQL shows it with capital B (SQL query is SELECT * FROM information_schema.tables where table_schema = 'testdb1';). But immediately after that we create index CREATE UNIQUE INDEX Busy_busy_unique ON Busy (busy) and our table renamed to busy in lowercase. So far so good, but org.jetbrains.exposed.sql.tests.shared.DDLTests#addAutoPrimaryKey also has Busy-table logic and it checks if Busy table exists. When we load all table names in org.jetbrains.exposed.sql.vendors.VendorDialect#allTablesNames we load table name as busy, no chance to convert to Busy. org.jetbrains.exposed.sql.vendors.VendorDialect#getInProperCase checks that both TransactionManager.current().db.metadata.storesUpperCaseIdentifiers() and TransactionManager.current().db.metadata.storesLowerCaseIdentifiers() are false and org.jetbrains.exposed.sql.Table#nameInDatabaseCase do not converts table name to lowercase. After that org.jetbrains.exposed.sql.vendors.VendorDialect#tableExists can't find table Busy and org.jetbrains.exposed.sql.SchemaUtils#createStatements generates statements to create table Busy.

CREATE TABLE IF NOT EXISTS Busy (busy BOOLEAN NOT NULL) works fine and does nothing, but index creation CREATE UNIQUE INDEX Busy_busy_unique ON Busy (busy) fails with weird Duplicate key name 'Busy_busy_unique'. And each isolated test works fine.

I suggest that org.jetbrains.exposed.sql.vendors.VendorDialect#tableExists should ignore storesUpperCaseIdentifiers()/storesUpperCaseIdentifiers() and compare lowercases against lowercases. It's possible to support system property that forces to compare table names without converting it to lowercase. Probably, org.jetbrains.exposed.sql.vendors.VendorDialect#allTablesNames shouldn't do any conversion.

Also I am not sure that we need to use org.jetbrains.exposed.sql.SchemaUtils#withDataBaseLock in org.jetbrains.exposed.sql.SchemaUtils#createMissingTablesAndColumns.

Support time math

There are a number of time math functions, that while supported in Kotlin and commonly in databases (I don't know exactly how prevalent they are, but I suspect very), aren't possible to express in Exposed without resorting to custom functions.

For example <timestamp> + <duration> * <int>.

Currently, arithmetic ops on time types require using the same type, which can get a bit non-sensical.

I think the two primary ops that would be good to have are <timestamp> +|- <duration> and <duration> *|/ <scalar>

Allow "For Update" to select which table it references
For update selects the second table in joins, this is not what you want when building a lock. We ideally should be able to define the table it is targeting.

Example join:

Equine .leftJoin(EquineStatuses) .slice(Equine.columns.plus(EquineStatuses.columns)) .select { Equine.id eq id } .orderBy(Equine.barnName to SortOrder.ASC, EquineStatuses.added to SortOrder.DESC) .let { if (forUpdate) it.forUpdate() else it }

Will throw: org.postgresql.util.PSQLException: ERROR: FOR UPDATE cannot be applied to the nullable side of an outer join

We need something like:

Eager loading does not support chunking, which leads to ORA-01795
Software details

Database: Oracle 19.1 Oracle driver version: 19.8.0.0 Kotlin version: 1.7.10 Exposed version: 0.40.1

Exception:

WARN Exposed - Transaction attempt #0 failed: java.sql.SQLSyntaxErrorException: ORA-01795: maximum number of expressions in a list is 1000

Code:

// Entity class Poll(id: EntityID<Long>) : LongEntity(id) { companion object : LongEntityClass<Poll>(OldPolls) var path by OldPolls.path var pollId by OldPolls.pollId val options by PollOption referrersOn OldPollOptions.poll } // Service fun getAllPolls(): List<PollDto> = transaction { Poll.all().with(Poll::options).toList() }

Explanation:

Eager loading is basically some aggregating request with all ids that are put into IN clause. In the case of the Oracle database, there is a limitation that restricts the maximum size of IN clause to 1000 entries.

Possible solution:

By adding some alternative "withChunked" method or overloading existing "with" with an extra Int parameter, so all the data can be pre-fetch in batches.
