Question

For example:

SELECT COUNT(ID) FROM My_Table
WHERE ID < 

(SELECT ID FROM My_Table
WHERE ID LIKE '%4'
ORDER BY ID LIMIT 1)    

My_Table:

  X          ID    Y     
------------------------
|      |     A1  |     |
------------------------
|      |     B2  |     |
------------------------
|      |     C3  |     |
------------------------ -----Page 1
|      |     D3  |     |
------------------------
|      |     E3  |     |
------------------------
|      |     F5  |     |
------------------------ -----Page 2
|      |     G5  |     |
------------------------
|      |     F6  |     |
------------------------
|      |     G7  |     | -----Page 3

There is no data ending in 4 but there still are 5 rows that end in something less than “%4“.

However, in this case were there is no match, so SQLite only returns 0

I get it is not there but how do I change this behavior to still return number of rows before it, as if it was there?

Any suggestions?

Thank You.

SELECT COUNT(ID) FROM My_Table
WHERE ID < (SELECT ID FROM My_Table
  WHERE SUBSTRING(ID, 2) >= 4
ORDER BY ID LIMIT 1)
