Doctrine - How to print out the real sql not just the prepared statement

Question

We re using Doctrine  a PHP ORM  I am creating a query like this    q   Doctrine Query  create  - gt select  id  - gt from  MyTable      and then in the function I m adding in various where clauses and things as appropriate  like this   q- gt where  normalisedname     OR name       array  string   originalString      Later on  before execute  -ing that query object  I want to print out the raw SQL in order to examine it  and do this    q- gt getSQLQuery      However that only prints out the prepared statement  not the full query  I want to see what it is sending to the MySQL  but instead it is printing out a prepared statement  including   s  Is there some way to see the  full  query

You can use     query- gt getSQL      If you are using MySQL you can use Workbench to view running SQL statements  You can also use view the running query from mysql by using the following     SHOW FULL PROCESSLIST  G

I made some research for this topic  because i wanted to debug a generated SQL query and execute it in the sql editor  As seen in all the answers  it is a highly technical topic  When i assume that the initial question is base on dev-env  one very simple answer is missing at the moment  You can just use the build in Symfony profiler  Just click on the Doctrine Tab  Scroll to the query you want to inspect  Then click on  quot view runnable query quot  and you can paste your query directly in your SQL editor More UI base approach but very quick and without debugging code overhead

Doctrine is not sending a  real SQL query  to the database server   it is actually using prepared statements  which means     Sending the statement  for it to be prepared  this is what is returned by  query- gt getSql    And  then  sending the parameters  returned by  query- gt getParameters    and executing the prepared statements   This means there is never a  real  SQL query on the PHP side     so  Doctrine cannot display it

TL DR   qb          your query builder  query    qb- gt getQuery       temporarily enable logging for your query  will also work in prod env   conf    query- gt getEntityManager  - gt getConnection  - gt getConfiguration     backupLogger    conf- gt getSQLLogger     logger   new  Doctrine DBAL Logging DebugStack     conf- gt setSQLLogger  logger      execute query  res    query- gt getResult     conf- gt setSQLLogger  backupLogger     restore logger for other queries  params        query    gt  array pop  logger- gt queries    extract query log details     your other twig params here      return  params    send this to your twig template      in your twig files  use Doctrine s twig helpers filters      show raw query      query sql        doctrine replace query parameters query params     highlighted     query sql        doctrine replace query parameters query params  doctrine pretty query highlight only   true        highlighted and formatted  i e  with tabs and newlines      query sql        doctrine replace query parameters query params  doctrine pretty query      Explanation   The other answers mentioning that Prepared statement are actually  real queries  are right  but they don t answer the obvious asker s expectation    Every developer wants to display a  runnable query  for debugging  or to display it to the user     So  I looked into Symfony profiler s source to see how they do it  The Doctrine part is Doctrine s responsibility so they made a doctrine-bundle to integrate with Symfony  Having a look at the doctrine-bundle Resources views Collector db html twig file  you will find out how they do it  this might change across versions   Interestingly  they created twig filters that we can reuse  see above    For everything to work we need to enable Logging for our query  There are multiple ways to do this and here I use DebugStack which allows to log queries without actually printing them  This also ensure that this will work in production mode if this is what you need     If you need further formatting  you will see that they include some CSS in a style tag  so simply  steal  it       highlight pre   margin  0  white-space  pre-wrap     highlight  keyword     color   8959A8  font-weight  bold     highlight  word        color   222222     highlight  variable    color   916319     highlight  symbol      color   222222     highlight  comment     color   999999     highlight  backtick    color   718C00     highlight  string      color   718C00     highlight  number      color   F5871F  font-weight  bold     highlight  error       color   C82829      Hope  this will help  -

You can easily access the SQL parameters using the following approach        result    qb- gt getQuery  - gt getSQL         param values             col names              foreach   result- gt getParameters   as  index   gt   param                              param values     param- gt getValue                     col names     param- gt getName                    echo rtrim  param values            echo rtrim  col names             So if you printed out the  param values and  col names   you can get the parameter values passing through the sql and respective column names   Note   If  param returns an array  you need to re iterate  as parameters inside IN      usually comes is as a nested array   Meantime if you found another approach  please be kind enough to share with us     Thank you

getSqlQuery   does technically show the whole SQL command  but it s a lot more useful when you can see the parameters as well   echo  q- gt getSqlQuery    foreach   q- gt getFlattenedParams   as  index   gt   param    echo   index   gt   param     To make this pattern more reusable  there s a nice approach described in the comments at Raw SQL from Doctrine Query Object

You can check the query executed by your app if you log all the queries in mysql   http   dev mysql com doc refman 5 1 en query-log html  there will be more queries not only the one that you are looking for but you can grep for it   but usually - gt getSql    works  Edit   to view all the mysql queries I use   sudo vim  etc mysql my cnf    and add those 2 lines    general log   on general log file    tmp mysql log   and restart mysql

There is no other real query  this is how prepared statements work  The values are bound in the database server  not in the application layer  See my answer to this question  In PHP with PDO  how to check the final SQL parametrized query   Repeated here for convenience    Using prepared statements with parametrised values is not simply another way to dynamically create a string of SQL  You create a prepared statement at the database  and then send the parameter values alone  So what is probably sent to the database will be a PREPARE      then SET     and finally EXECUTE      You won t be able to get some SQL string like SELECT   FROM      even if it would produce equivalent results  because no such query was ever actually sent to the database
