Copy generated files to your project. Configure the database manager. Just enjoy the. ( 1 ) Create your SQLite database using your favourite SQLite database manager. I need to pass ID, which is a primary key in SQLite Database in android app, to get the data from the Database related to the list item in ListView. When the data is received, it is then passed to another activity using intent. Everything else is working properly but I am not able to get the ID of the row in the Database according to list item. Nov 01, 2017  Lol, that's standard 'problem' with multiple non-synchronized DB. First of all - if you want to be able to create any unique objects at API, as well as at. Set to true to let SQLite generate the unique id. When set to true, the SQLite type affinity for the field should be INTEGER. If the field type is long or int (or its TypeConverter converts it to a long or int ), Insert methods treat 0 as not-set while inserting the item. If the field's type is Integer.

  • SQLite AUTOINCREMENT is a keyword used for auto incrementing a value of a field in the table. We can auto increment a field value by using AUTOINCREMENT keyword when creating a table with specific column name to auto increment.
  • A primary key is a column or group of columns used to identify the uniqueness of rows in a table. Each table has one and only one primary key. SQLite allows you to define primary key in two ways: First, if the primary key has only one column, you use the PRIMARY KEY column constraint to define the primary key as follows.

    Punnett square generator worksheet answer key. Hmm think Insert by definition creates a new row, I don't know if what you want to do is easily done with SQLite.Net/sqlite.
    What kind of schema does the database have?

    This may also be a limitation of SQLite.Net.

  • I know it works with plain SQLite. If I specify a value there for the PK, it will use that one (and of course fail if that key already exists). In Sqlite.Net it ignores what I set and uses its own. This happens with auto increment and without.

  • SQLite.Net is not very big, I suggest you just step trough see what it does, you may well be correct in that it does not handle that case.

  • I figured it out. It was my bad. There is no issue. If a value for a PK is set in the model, that value will be stored just fine. My test case was simply f**** up. :-)

  • Ah, well that can happen to the best of us ;P

    Good to hear you got it working.

Lol, that's standard 'problem' with multiple non-synchronized DB.

Gta v activation key generator. First of all - if you want to be able to create any unique objects at API, as well as at multiple mobile devices side, you need to have:

  • YourModelUniqueApi1:1 table + YourModelTempLocal table
    OR:

  • YourModel table with two ID's colum - LocalID (any autoincrement/autogenerated/guid ID, and it would be PRIMARY KEY at mobile side) + COMPLETELLY UNIQUE ID column (based on objects ID's at API side).
    LocalID is used only at mobile app side, and it's not used by API side.

Foreign Key

When your object is local only (hasn't been synchronized with API yet), it should have only LocalID filled, and ID 0. When your object has been synchronized with API, ID should match API object ID.

Sqlite Integer Primary Key

You can implement it with your way - to check next available ID every time, because you have multiple mobile devices, and you have objects at API side with ID's 1, 2, 3, 4, 5, you can in the same moment, try to create new object at TWO DIFFERENT mobile devices with ID 6, which would lead conflict at API side later on.
