Here is my query given below.
select * from data where value = "yes";
My id is auto increment and below there is result of given query.
id || value 1 || yes 3 || yes 4 || yes 6 || yes 9 || yes
How to use ROW_NUMBER in sqlite? So that i can get result which is given below.
NoId || value 1 || yes 2 || yes 3 || yes 4 || yes 5 || yes
ROW_NUMBER AS NoId.
Introduction to SQLite ROW_NUMBER() functionThe ROW_NUMBER() is a window function that assigns a sequential integer to each row of a query's result set. Rows are ordered starting from one based on the order specified by the ORDER BY clause in the window definition.
ROW_NUMBER function is a SQL ranking function that assigns a sequential rank number to each new record in a partition. When the SQL Server ROW NUMBER function detects two identical values in the same partition, it assigns different rank numbers to both.
ROWID doesn't enumerate the rows, it gives you the row ID, which is an internal ID used by sqlite, but ROW_NUMBER() is a function that generates sequential numbers for every result set.
The ROW_NUMBER() is a window function that assigns a sequential integer to each row within the partition of a result set. The row number starts with 1 for the first row in each partition.
SQLite Release 3.25.0 will add support for window functions
2018-09-15 (3.25.0)
- Add support for window functions
Window Functions :
A window function is a special SQL function where the input values are taken from a "window" of one or more rows in the results set of a SELECT statement.
SQLite supports the following 11 built-in window functions:
row_number()
The number of the row within the current partition. Rows are numbered starting from 1 in the order defined by the ORDER BY clause in the window definition, or in arbitrary order otherwise.
So your query could be rewritten as:
select *, ROW_NUMBER() OVER(ORDER BY Id) AS NoId from data where value = "yes";
