Question

I have a question – I have finished the database (SQLite), with updates, I analyze the structure and see whether I need to add new data or change the value in existing positions database. So I have a question – is it possible to replace the values ​​in the entire line at once (that is, in all cells (which are the same id) columns), or there is a possibility to replace the values ​​for each column.

Answer 1

If you have the id of the row to update, you can use the SQLiteDatabase.update() (docs here).

As you can see in the update() function, you use ContentValues to udpate the row, and provide the row id in the whereClause of the function. Inside the ContentValues, you can put new values of columns, as you’d normally do for an insert:

ContentValues cv = new ContentValues();
cv.putString("row1Name","value1");
cv.putString("row2Name","value2");

etc. The update call would be something like

db.update("table_name", cv, "row_id=?", new String[]{""=rowId);
