如何删除where子句（zend框架）上的特定条件？

Question

I have the following query generated by the default library of a third party framework

SELECT COUNT(*) AS "total_rows" FROM "papers" WHERE (papers.paper_trash=0 OR papers.paper_trash IS NULL) AND (paper_category_id='7') AND (qtdavaliacoes='0')

I know that if I use a $query->reset(Zend_Db_Select::WHERE); it will clear the where clause completely, is it possible to clear only the AND (qtdavaliacoes='0') condition from it using zend?

Answer 1

As per the documentation , it is not possible to reset only part of the WHERE condition. You would need to either:

• reset the whole WHERE condition and add the ones needed ;
• re-instantiate your object and re-build your query all over again.
