I want to write SQLite statement something like this:
SELECT * FROM Table WHERE RowNumber BETWEEN 1 AND 10;
but i don't have such column RowNumber. I have primary key in my table. But is there row number by default that i could use ?
Also i am searching info about writing more complicated SQLite statement. So if you have some links in bookmarks please share.
Thanks.

Using SQLite ROW_NUMBER() for paginationThe ROW_NUMBER() function can be useful for pagination. For example, if you want to display customers information on a table by pages with 10 rows per page. In this example: First, the ROW_NUMBER() function assigns each row a sequential integer.
The rowid of a rowid table can be accessed (or changed) by reading or writing to any of the "rowid" or "oid" or "_rowid_" columns. Except, if there is a declared columns in the table that use those special names, then those names refer to the declared columns, not to the underlying rowid.
Suppose there are 100 rows in your table and you want to retrieve only specified rows e.g. 10th to 20th. You can do this by using ROW_NUMBER () function provided by Sql server. your table name. It will retrieve the records from rows 10 to 20 from your table.
To select data from an SQLite database, use the SELECT statement. When you use this statement, you specify which table/s to select data from, as well as the columns to return from the query. You can also provide extra criteria to further narrow down the data that is returned.
You want to use LIMIT and OFFSET
SELECT * FROM Table LIMIT 10 OFFSET 0
Which can also be expressed with the following shorthand syntax
SELECT * FROM Table LIMIT X,Y
Where X represents the offset, which is exclusive, and Y represents the quantity, so for example
SELECT * FROM Table LIMIT 50,50
Would return rows 51-100

The automatically-created rowid for a table can be accessed by a few different names. From the SQLite documentation:
Every row of every SQLite table has a 64-bit signed integer key that uniquely identifies the row within its table. This integer is usually called the "rowid". The rowid value can be accessed using one of the special case-independent names "rowid", "oid", or "_rowid_" in place of a column name.
