Question

The documentation for SQLiteDatabase.query says that the selectionArgs will be bound as strings.

What is the recommended way to perform a query with an integer parameter?

Is it this:

int value = 10;
Cursor cursor = database.query(
    "TABLE_X", 
    new String[] { "COLUMN_A", "COLUMN_B" },
    "COLUMN_C = " + value,
    null,
    null,
    null,
    null);

Or is it this:

int value = 10;
Cursor cursor = database.query(
    "TABLE_X", 
    new String[] { "COLUMN_A", "COLUMN_B" },
    "COLUMN_C = ?",
    new String[] { Integer.toString(value) },
    null,
    null,
    null);

Or something else?

Answer 1

Second option with ? is the suggested way of using query method.

selectionArgs: You may include ?s in selection, which will be replaced by the values
from selectionArgs, in order that they appear in the selection. The
values will be bound as Strings.
