# Extensions for Jetpack Room
## Room Extensions – Aggregate
[][room-extensions-release]
[][room-extensions-snapshot]
Artifact `it.czerwinski.android.room:room-extensions` aggregates artifacts:
- `room-database`,
- `room-database-sql`.
You can either use `room-extensions` or any combination of the other artifacts, whichever suites your project.
Kotlin
```kotlin
dependencies {
implementation("androidx.room:room-runtime:2.4.2")
implementation("it.czerwinski.android.room:room-extensions:[VERSION]")
}
```
Groovy
```groovy
dependencies {
implementation 'androidx.room:room-runtime:2.4.2'
implementation 'it.czerwinski.android.room:room-extensions:[VERSION]'
}
```
## Room Database Extensions
[][room-database-release]
[][room-database-snapshot]
Kotlin
```kotlin
dependencies {
implementation("androidx.room:room-runtime:2.4.2")
implementation("it.czerwinski.android.room:room-database:[VERSION]")
}
```
Groovy
```groovy
dependencies {
implementation 'androidx.room:room-runtime:2.4.2'
implementation 'it.czerwinski.android.room:room-database:[VERSION]'
}
```
### Room Database Builders
#### `roomDatabaseBuilder`
Creates a `RoomDatabase.Builder` for a persistent database with type `T` and the given `name`.
```kotlin
val database = context.roomDatabaseBuilder().build()
```
or:
```kotlin
val database = context.roomDatabaseBuilder(name = "database").build()
```
#### `roomInMemoryDatabaseBuilder`
Creates a `RoomDatabase.Builder` for an in memory database with type `T`.
```kotlin
val database = context.roomInMemoryDatabaseBuilder().build()
```
## Room Database SQL Extensions
[][room-database-sql-release]
[][room-database-sql-snapshot]
Kotlin
```kotlin
dependencies {
implementation("androidx.room:room-runtime:2.3.0")
implementation("it.czerwinski.android.room:room-database-sql:[VERSION]")
}
```
Groovy
```groovy
dependencies {
implementation 'androidx.room:room-runtime:2.3.0'
implementation 'it.czerwinski.android.room:room-database-sql:[VERSION]'
}
```
### SQL Script Executor
```kotlin
val database: SupportSQLiteDatabase
val sqlScriptExecutor = SQLScriptExecutor {
+"""
insert into users(id, username, password) values (1, 'root', 'qwerty');
insert into user_roles(user_id, role_id) values (1, 1);
"""
}
sqlScriptExecutor.executeOn(database)
```
### Room Database Builder Extensions
#### Populate From SQL
Configures Room to populate a newly created database with an SQL script.
```kotlin
val database = context.roomDatabaseBuilder()
.populateFromSql {
+"""
insert into users(id, username, password) values (1, 'root', 'qwerty');
insert into user_roles(user_id, role_id) values (1, 1);
"""
}
.build()
```
#### Populate From SQL Asset
Configures Room to populate a newly created database with an SQL script located in the application `assets/` folder.
```kotlin
val database = context.roomDatabaseBuilder()
.populateFromSqlAsset(context, "sql/populate.sql")
.build()
```
#### Add Migration From SQL
Adds an SQL script migration to the builder.
```kotlin
val database = context.roomDatabaseBuilder()
.addMigrationFromSql(startVersion = 1, endVersion = 2) {
+"""
create table if not exists users (
id integer primary key asc,
username text not null,
password text not null
);
"""
}
.build()
```
#### Add Migration From SQL Asset
Adds a migration to the builder, executing an SQL script located in the application `assets/` folder.
```kotlin
val database = context.roomDatabaseBuilder()
.addMigrationFromSqlAsset(startVersion = 1, endVersion = 2, context, "sql/migrate_1_2.sql")
.build()
```
#### Add Migrations From SQL Assets
Adds migrations to the builder, executing an SQL scripts located in the application `assets/` folder,
matching the given format.
```kotlin
val database = context.roomDatabaseBuilder()
.addMigrationsFromSqlAssets(context, sqlFilePathFormat = "sql/migrate_{}_{}.sql")
.build()
```
