Laurent writes "how to manage a tree structure with SQL ?
i mean more precisely that i have already made up a table with a id column + another column that "point" to the id of the direct parent wich allow me to use a single table to store a tree structure, there is also a level column that store the "distance" of each element from the root and the last column store the order of the element that have the same parent.
i still cannot find what kind of select did i have to use, with what kind of arguments,... could you show me a little exemple ?
thanks guys !
Laurent" |
