Select objects have a   toString   method in Zend Framework   From the Zend Framework manual    select    db- gt select                - gt from  products      sql    select- gt   toString    echo   sql n       The output is the string       SELECT   FROM  products    An alternative solution would be to use the Zend Db Profiler  i e    db- gt getProfiler  - gt setEnabled true       your code  this- gt update  up value  customer id     userid   and address id  lt  gt     data  address Id       Zend Debug  dump  db- gt getProfiler  - gt getLastQueryProfile  - gt getQuery     Zend Debug  dump  db- gt getProfiler  - gt getLastQueryProfile  - gt getQueryParams      db- gt getProfiler  - gt setEnabled false     http   framework zend com manual en zend db select html

You can use Zend Debug  Dump  select- gt assemble     to get the SQL query    Or you can enable Zend DB FirePHP profiler which will get you all queries in a neat format in Firebug  even UPDATE statements    EDIT  Profiling with FirePHP also works also in FF6 0   not only in FF3 0 as suggested in link

The query returned from the profiler or query object will have placeholders if you re using those   To see the exact query run by mysql you can use the general query log   This will list all the queries which have run since it was enabled  Don t forget to disable this once you ve collected your sample  On an active server  this log can fill up very fast   From a mysql terminal or query tool like MySQL Workbench run   SET GLOBAL log output    table   SET GLOBAL general log   1    then run your query  The results are stored in the  mysql general log  table   SELECT   FROM mysql general log   To disable the query log   SET GLOBAL general log   0    To verify it s turned off   SHOW VARIABLES LIKE  general      This helped me locate a query where the placeholder wasn t being replaced by zend db  Couldn t see that with the profiler
