Expo SQLite 'PRAGMA user_version' not working

Environment

Environment: OS: Windows 10 Node: 6.10.2 Yarn: 1.3.2 npm: 5.6.0

Packages: (wanted => installed) expo: ^25.0.0 => 25.0.0 react: 16.2.0 => 16.2.0 react-native: 0.52.0 => 0.52.0

Steps to Reproduce

Execute command tx.executeSql(‘pragma user_version’).

Expected Behavior

It should return database’s user_version pragma value.

Actual Behavior

It works with iOS device/simulator, but does not work with Android device/emulator and throws the following error: [Error: unknown error (code 0): Queries can be performed using SQLiteDatabase query or rawQuery methods only.]

Changing pragma’s value, e.g. tx.executeSql(‘pragma user_version=1’) works both on iOS and Android.

Running into similar error. I’m trying to make the app add a column to an existing table if it doesn’t already exist, and the relevant PRAGMA query works correctly on iOS, but fails on Android.

Query: PRAGMA table_info(my_table); (SQLite docs) Error: Error: unknown error (code 0): Queries can be performed using SQLiteDatabase query or rawQuery methods only.

Tested failing on Android devices:

• Pixel 2 (8.1.0)
• HTC 10 (8.0.0)
• Moto RAZR M (4.4.2)

Using Expo SDK version 27.0.2 and Expo client version 2.5.2 on all 3 devices.
