I have a SQL table with this nested structure:
CREATE TABLE items (`id` INTEGER, `item_name` VARCHAR(6), `parent_id` INTEGER, `list_order` INTEGER);My SQLite version does not support window function, currently my query at link SQLite query are returning as follow the result, but it's not ordered according to list_order, another detail is that the list_order column could come with all values equal to zero.
id name_item parent_id level path_index list_order--------------------------------------------------------------- 1 Pois 0 0 1 4 2 Então 0 0 2 5 3 Teste 0 0 3 3 11 Teste 3 3 1 3.1 2 12 Teste 2 3 1 3.2 0 13 Teste 1 3 1 3.3 1 4 Fundo 0 0 4 2 7 Profundo 4 1 4.1 1 8 Dhdhd 4 1 4.2 0 9 Gagagaga 8 2 4.2.1 1 10 Fsfsfsfs 8 2 4.2.2 0 5 Profundo 0 0 5 1 6 Gigante 0 0 6 6 14 Teste 0 0 7 0What I want the path_index column to follow list_order and level columns, like here:
id name_item parent_id level path_index list_order--------------------------------------------------------------- 14 Teste 0 0 1 0 5 Profundo 0 0 2 1 4 Fundo 0 0 3 2 8 Dhdhd 4 1 3.1 0 10 Fsfsfsfs 8 2 3.1.1 0 9 Gagagaga 8 2 3.1.2 1 7 Profundo 4 1 3.2 1 3 Teste 0 0 4 3 12 Teste 2 3 1 4.1 0 13 Teste 1 3 1 4.2 1 11 Teste 3 3 1 4.3 2 1 Pois 0 0 5 4 2 Então 0 0 6 5 6 Gigante 0 0 7 6How can I align the path_index sorted according to list_order and level columns?
