服务器端SQL包括

Question

This is the php version of this question server-side SQL library

Is there a library that can break apart sql into fully server-side logic?

As an example consider this basic query SELECT table1column1, table2column1 FROM table1, table2 WHERE table1.id = 1 AND table2.table1id = table1.id; which is ~5x slower than breaking up the SELECT into 2 SELECT s SELECT ing off the PRIMARY for both, assuming that table2.table1id is not the PRIMARY .

I would want a library, that in this case, does just that, breaks up the single query into two. It doesn't have to parse sql to understand what one wants rather it would probably be best in something like this format basicJoin($table1columnsList, $table2columnsList, $table1name, $table2name, $table1id, $table2table1idColumnName) .

This function would

1. SELECT the table1 columns specified into an array based upon $table1id (the PRIMARY )
2. SELECT all table2 ids ( table2 's PRIMARY ) and table1id s into an array and find the proper table2 id
3. use the table2 id above to SELECT the table2 columns specified into an array (or in the table1 array)

Handling my logic in php only has vastly decreased processing lag and processing lag spikes, but it's tedious writing out all of this logic.

Does it already exist? If so, where?

Many thanks in advance!

If you're into OOP there's Propel - http://propelorm.org/ It handles all the logic and gives you methods like joinWith() and getThis() , setThat() , save() .

It appears Propel does break queries apart, so that it can deliver several objects that can be saved individually.
