$query->num_rows(); can not get the number of rows - El Forum - 05-11-2009 [eluser]test2009[/eluser] I retrieve the records Ifm ODBC / Access database 2007 it works $this->db->where('EMAIL', $strSearch); $data['query']= $this->db->get('MYTABLE'); I can list the records all OK. But in view file echo $query->num_rows(); gives -1 result What is wrong? $query->num_rows(); can not get the number of rows - El Forum - 05-11-2009 [eluser]Dam1an[/eluser] Having a quick look at the ODBC driver, it just returns the value of odbc_num_rows which is a PHP function That function returns -1 on error, so its a PHP/ODBC fault, not a CI problem Are you getting anything in your error logs? (Make sure you have logging enabled) $query->num_rows(); can not get the number of rows - El Forum - 05-11-2009 [eluser]test2009[/eluser] yes, I hv enabled the logs at 4 level No error with database. the result is -1 even though there are records returned from query. $query->num_rows(); can not get the number of rows - El Forum - 05-15-2009 [eluser]pickupman[/eluser] I recently ran into this same problem using an Access database. If you look into the CI library /system/database/drivers/odbc_result.php, the function num_rows() is null. The function is commented that ODBC does not support it. I used the following query. Code: //Query DB for number of rows in result $query->num_rows(); can not get the number of rows - El Forum - 05-15-2009 [eluser]Jondolar[/eluser] Why are you calling $query->num_rows(); You are using an ActiveRecord call that returns an array. You have no object to call num_rows() against. If you want to continue to use ActiveRecord you need to call: $this->db->count_all('my_table'); Basically, you are mixing ActiveRecord functions with the database class functions |
