(Win, Linux, Mac, Android, and iOS) By using it, you can write platform independent Sqlite code in your Kotlin common code. All the SQL statements, of course, are generated automatically. Kotlin Sqlite Bindings This project provides kotlin multiplatform bindings for Sqlite3. It provides strong-typed and flexible SQL DSL and convenient sequence APIs to reduce our duplicated effort on database operations. To fix this, you just need to change the Entity class a bit, and allow the fields to be Nullable. Ktorm is a lightweight and efficient ORM Framework for Kotlin directly based on pure JDBC. Val title: String In Kotlin, this means that title can never be null. And thus, when you try to add a record with one of these values as null, you will get an SQLiteConstraintException. The generated columns like title, description, info and url will be marked as NOT NULL. This happens because the generated schema for your tables mark some of the table’s columns as NOT NULL.įor example, if you Entity class looks like this: = 'books') Kotlin AndroidCodility / TodoApp-Sqlite Star 10 Code Issues Pull requests Android application to make Todo-list to Organize your to-do, work using offline mode with SQlite storage using Kotlin Programming Language. You might come across this error when you are using Room database on Android.

Here is the code that makes the call to the DB btnGetID.Caused by: :Ĭonstraint failed: (code 1299 SQLITE_CONSTRAINT_NOTNULL) Say we want the id but only know the name in table Be aware that because androidx.sqlite had some missing nullability annotations you might experience source incompatibility errors if your sources are in Kotlin and the code was inferring the wrong nullability. How do we query a SQLite database for one record? The library group androidx.sqlite sources has been converted from Java to Kotlin. We can not believe we are asking this question!
