Can I Run IOS Emulator On Windows Using Android Studio Avd Manger?

Answer : No, it is not possible. Any iOS operations require Xcode. So either use an OSX virtual machine or use a mac. But from Windows, you won't be able to run an iOS emulator. Unfortunately it's impossible :( Flutter app can run on Android and IOS emulators with Android Studio, but ONLY on Apple machines (not Windows). So if you have Android Studio installed on Windows machine you won't have IOS emulator. This info isn't obvious in Android Studio documentation, but you can find more details in Flutter installation guide: macOS install (Flutter, Android Studio, emulators for Android and IOS) Windows install (Flutter, Android Studio, emulator for Android) So in your case the best way is to develop flutter apps on your Mac.

Convert Timestamp To Date In Oracle SQL

Answer : CAST(timestamp_expression AS DATE) For example, The query is : SELECT CAST(SYSTIMESTAMP AS DATE) FROM dual; Try using TRUNC and TO_DATE instead WHERE TRUNC(start_ts) = TO_DATE('2016-05-13', 'YYYY-MM-DD') Alternatively, you can use >= and < instead to avoid use of function in the start_ts column: WHERE start_ts >= TO_DATE('2016-05-13', 'YYYY-MM-DD') AND start_ts < TO_DATE('2016-05-14', 'YYYY-MM-DD') Format like this while selecting: to_char(systimestamp, 'DD-MON-YYYY') Eg: select to_char(systimestamp, 'DD-MON-YYYY') from dual;

CREATE VIEW Must Be The Only Statement In The Batch

Answer : Just as the error says, the CREATE VIEW statement needs to be the only statement in the query batch. You have two option in this scenario, depending on the functionality you want to achieve: Place the CREATE VIEW query at the beginning CREATE VIEW showing as select tradename, unitprice, GenericFlag from Medicine; with ExpAndCheapMedicine(MostMoney, MinMoney) as ( select max(unitprice), min(unitprice) from Medicine ) , findmostexpensive(nameOfExpensive) as ( select tradename from Medicine, ExpAndCheapMedicine where UnitPrice = MostMoney ) , findCheapest(nameOfCheapest) as ( select tradename from Medicine, ExpAndCheapMedicine where UnitPrice = MinMoney ) Use GO after the CTE and before the CREATE VIEW query -- Option #2 with ExpAndCheapMedicine(MostMoney, MinMoney) as ( select max(unitprice), min(unitprice) from Medicine ) , findmostexpensive(nameOfExpensive) as ( select tradename from Medicine, ExpAndCheapMedicine

Cannot Create A New Table After "DROP SCHEMA Public"

Answer : The error message pops up when none of the schemas in your search_path can be found. Either it is misconfigured. What do you get for this? SHOW search_path; Or you deleted the public schema from your standard system database template1 . You may have been connected to the wrong database when you ran drop schema public cascade; As the name suggests, this is the template for creating new databases. Therefore, every new database starts out without the (default) schema public now - while your default search_path probably has 'public' in it. Just run (as superuser public or see mgojohn's answer): CREATE SCHEMA public; in the database template1 (or any other database where you need it). The advice with DROP SCHEMA ... CASCADE to destroy all objects in it quickly is otherwise valid. That advice can cause some trouble if you have an application user (like 'postgres') and run the DROP/CREATE commands as a different user. This would happen

Androidx.test.InstrumentationRegistry Is Deprecated

Answer : You can use InstrumentationRegistry.getInstrumentation().getTargetContext() in the most cases from androidx.test.platform.app.InstrumentationRegistry . If you need the Application, you can use ApplicationProvider.getApplicationContext<MyAppClass>() . If you haven't already, I think you can also use the new test dependency: androidTestImplementation 'androidx.test:core:1.0.0-beta02' . When you're using Android X you need to make sure you have the following in your app's build.gradle file androidTestImplementation 'androidx.test:core:1.1.0' androidTestImplementation 'androidx.test.ext:junit:1.1.0' The second one is to make sure you have the correct AndroidJUnit4 to use in your tests. Make sure you import both of these. import androidx.test.platform.app.InstrumentationRegistry import androidx.test.ext.junit.runners.AndroidJUnit4 Now instead of using val context = InstrumentationRegistry.getContext() you can use the lin
