看起来您正在尝试将 2 个表合二为一 -> 加入，我认为您不能这样做。
从 Zend_Db_Select() 加入代码
/**
* Adds a JOIN table and columns to the query.
*
* The $name and $cols parameters follow the same logic
* as described in the from() method.
*
* @param array|string|Zend_Db_Expr $name The table name.
* @param string $cond Join on this condition.
* @param array|string $cols The columns to select from the joined table.
* @param string $schema The database name to specify, if any.
* @return Zend_Db_Select This Zend_Db_Select object.
*/
public function join($name, $cond, $cols = self::SQL_WILDCARD, $schema = null)
{
return $this->joinInner($name, $cond, $cols, $schema);
}
这是 from() 的注释块
/**
* Adds a FROM table and optional columns to the query.
*
* The first parameter $name can be a simple string, in which case the
* correlation name is generated automatically. If you want to specify
* the correlation name, the first parameter must be an associative
* array in which the key is the correlation name, and the value is
* the physical table name. For example, array('alias' => 'table').
* The correlation name is prepended to all columns fetched for this
* table.
*
* The second parameter can be a single string or Zend_Db_Expr object,
* or else an array of strings or Zend_Db_Expr objects.
*
* The first parameter can be null or an empty string, in which case
* no correlation name is generated or prepended to the columns named
* in the second parameter.
*
* @param array|string|Zend_Db_Expr $name The table name or an associative array
* relating correlation name to table name.
* @param array|string|Zend_Db_Expr $cols The columns to select from this table.
* @param string $schema The schema name to specify, if any.
* @return Zend_Db_Select This Zend_Db_Select object.
*/
也许可以试试这样的方法：
$select = $this->_db->select()
//FROM table procurement_tbltenderevaluationcriteria AS evaluationcriteria, SELECT FROM
//COLUMNS ScoringCriteriaID and ScoringCriteriaWeight
->from(array('evaluationcriteria' => 'procurement_tbltenderevaluationcriteria'),
array('ScoringCriteriaID','ScoringCriteriaWeight'))
//JOIN TABLE procurement_tbltenderscoringcriteria AS scoringcriteria WHERE
//TenderId FROM TABLE scoringcriteria == TenderId FROM TABLE evaluationcriteria
->join(array('scoringcriteria' => 'procurement_tbltenderscoringcriteria'),
'scoringcriteria.TenderId=evaluationcriteria.TenderId')
//JOIN TABLE procurement_tbltenderapplications AS tenderapplications
->join(array('tenderapplications' => 'procurement_tbltenderapplications'))
//JOIN TABLE tblsupplier AS tendersupplier WHERE TenderInvitationContractorID FROM TABLE
// tenderapplications == UserID FROM TABLE tendersupplier
->join(array('tendersupplier' => 'tblsupplier'),
'tenderapplications.TenderInvitationContractorID=tendersupplier.UserID');
you may also need to alter your select() definition to allow joins:
//this will lock the tables to prevent data corruption
$this->_db->select(Zend_Db_Table::SELECT_WITHOUT_FROM_PART)->setIntegrityCheck(FALSE);
我希望我正确地阅读了您的意图，如果不是一直到那里，这应该会让您更接近。 （一个提示，使用较短的别名...）
