Yii 1.1 General Discussion

i think its more php problem maybe, but if you know please help.

On my local machine all code is parsed without error, but on production server it’s get error, which i can see in yii log




[error] [system.db.CDbCommand] Error in querying SQL: SELECT Object id #59 FROM ... etc.

and that rises error such




[error] [exception.CDbException] exception

'CDbException' with message 'CDbCommand failed to execute the SQL

statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column

'Object' in 'field list'' in

you see SELECT here is columns list FROM …

fixed… if you can explain why it breaks here


$criteria = new CDbCriteria(); 

$criteria->select = new CDbExpression('FLOOR(RAND() * '.$rowCount.') as offset');

but if i dont use CDbExpression class, than its ok


$criteria->select = 'FLOOR(RAND() * '.$rowCount.') as offset';

it was not designed for these kind of functions to include in sql query?

take a look at the documentation for CDbExpression

http://www.yiiframew…i/CDbExpression

it’s mainly used for CActiveRecord attribute values…

EDIT: don’t know why but this editor inserts <b></b> inside this link… so the link is not working!!!
