首先，我对kohana很新，但我对更受欢迎的Yii＆amp; amp; Yii2。
我正在使用复杂的配置，使用查询构建器从leap模型调用MsSQL数据库。现在我不得不优化代码但是遇到了错误，这很难自己解决。
MsSQL数据库的请求分为两部分。这是子查询，按原样执行：
$leap_subquery = DB_SQL::select($this->data_source())
->column('lg.SessionID','SESSION_ID')
->column(DB_SQL::expr("CAST(DATEADD(HOUR, 3, lg.MsgTimestamp) AS DATE)"),'ACTIVITY_DT')
->column(DB_SQL::expr("CAST(DATEADD(HOUR, 3, lg.MsgTimestamp) AS TIME(0))"),'ACTIVITY_TM')
->column(DB_SQL::expr("RIGHT(REPLACE(cr.ORIGINATINGNUMBER,'tel:',''),10)"),'PHONE_NUM')
->column(DB_SQL::expr("RIGHT(REPLACE(cr.DESTINATIONNUMBER,'tel:',''),5)"),'DESTINATION_NUM')
->column(DB_SQL::expr("CAST(CASE
WHEN UPPER(lg.ActivityName) = 'VDUID' THEN lg.VarValue
ELSE NULL
END AS VARCHAR(50))"),'CALL_ID')
->column(DB_SQL::expr("CASE
WHEN UPPER(LEFT(lg.ActivityName,21)) = 'КАЧЕСТВО_ОБСЛУЖИВАНИЯ'
THEN CAST(RIGHT(lg.ActivityName,1) AS NUMERIC)
ELSE NULL
END"),'SERVICE_QUALITY')
->column(DB_SQL::expr("CASE
WHEN UPPER(LEFT(lg.ActivityName,15)) = 'СКОРОСТЬ_ОТВЕТА'
THEN CAST(RIGHT(lg.ActivityName,1) AS NUMERIC)
ELSE NULL
END"),'RESPONSE_SPEED')
->column(DB_SQL::expr("CASE
WHEN UPPER(LEFT(lg.ActivityName,12)) = 'ВОПРОС_РЕШЁН' AND RIGHT(lg.ActivityName,1) = '1' THEN 1
WHEN UPPER(LEFT(lg.ActivityName,12)) = 'ВОПРОС_РЕШЁН' AND RIGHT(lg.ActivityName,1) = '2' THEN 0
ELSE NULL
END"),'QUESTION_SOLUTION')
->column(DB_SQL::expr("CASE
WHEN UPPER(LEFT(lg.ActivityName,18)) = 'ДОБРОЖЕЛАТЕЛЬНОСТЬ'
THEN CAST(RIGHT(lg.ActivityName,1) AS NUMERIC)
ELSE NULL
END"),'AMIABILITY')
->column(DB_SQL::expr("CASE
WHEN UPPER(LEFT(lg.ActivityName,7)) = 'ЯСНОСТЬ'
THEN CAST(RIGHT(lg.ActivityName,1) AS NUMERIC)
ELSE NULL
END"),'CLEARNESS')
->column(DB_SQL::expr("CASE
WHEN UPPER(LEFT(lg.ActivityName,14)) = 'ВНИМАТЕЛЬНОСТЬ'
THEN CAST(RIGHT(lg.ActivityName,1) AS NUMERIC)
ELSE NULL
END"),'ATTENTION')
->from('VPStats.dbo.VPAppLog','lg')
->join('INNER','VPStats.dbo.CDR','cr')->on('cr.SESSIONID','=','lg.SessionID')
->where(DB_SQL::expr("CAST(DATEADD(HOUR, 3, lg.MsgTimestamp) AS DATE)"), '=', DB_SQL::expr("CAST('".$date."' AS DATE)"))
->where(DB_SQL::expr("UPPER(lg.ApplicationID)"), '=', 'QUALITY')
->where_block('(')
->where(DB_SQL::expr("UPPER(LEFT(lg.ActivityName,21))"), '=', 'КАЧЕСТВО_ОБСЛУЖИВАНИЯ' )
->where(DB_SQL::expr("UPPER(LEFT(lg.ActivityName,15))"), '=', 'СКОРОСТЬ_ОТВЕТА', 'OR')
->where(DB_SQL::expr("UPPER(LEFT(lg.ActivityName,12))"), '=', 'ВОПРОС_РЕШЁН', 'OR')
->where(DB_SQL::expr("UPPER(LEFT(lg.ActivityName,18))"), '=', 'ДОБРОЖЕЛАТЕЛЬНОСТЬ', 'OR')
->where(DB_SQL::expr("UPPER(LEFT(lg.ActivityName,7))"), '=', 'ЯСНОСТЬ', 'OR')
->where(DB_SQL::expr("UPPER(LEFT(lg.ActivityName,14))"), '=', 'ВНИМАТЕЛЬНОСТЬ', 'OR')
->where(DB_SQL::expr("UPPER(lg.ActivityName)"), '=', 'VDUID', 'OR')
->where_block(')')
->statement(FALSE);
但是下一个查询应该从第一个查询一些数据：
$leap_query = DB_SQL::select($this->data_source())
->column(DB_SQL::expr("MAX(VP.ACTIVITY_DT"), 'date' )
->column(DB_SQL::expr("MAX(VP.ACTIVITY_TM"), 'time' )
->column(DB_SQL::expr("MAX(VP.PHONE_NUM)"), 'number' )
->column(DB_SQL::expr("MAX(VP.SERVICE_QUALITY)"), 'answer_1' )
->column(DB_SQL::expr("MAX(VP.QUESTION_SOLUTION)"), 'answer_2' )
->column(DB_SQL::expr("MAX(VP.RESPONSE_SPEED)"), 'answer_3' )
->column(DB_SQL::expr("MAX(VP.AMIABILITY)"), 'answer_4' )
->column(DB_SQL::expr("MAX(VP.CLEARNESS)"), 'answer_5' )
->column(DB_SQL::expr("MAX(VP.ATTENTION)"), 'answer_6' )
->column(DB_SQL::expr("MAX(VP.DESTINATION_NUM)"), 'skill' )
->column(DB_SQL::expr("MAX(VP.CALL_ID)"), 'call_id' )
->from(DB::expr("(".$leap_subquery.")"), 'VP')
->group_by(array('VP.SESSION_ID'))
->having(DB_SQL::expr("MAX( CALL_ID )"), 'IS NOT', NULL)
->having_block('(')
->having(DB_SQL::expr("MAX(VP.SERVICE_QUAILITY)"), 'IS NOT', NULL )
->having(DB_SQL::expr("MAX(VP.RESPONSE_SPEED)"), 'IS NOT', NULL, 'OR')
->having(DB_SQL::expr("MAX(VP.QUESTION_SOLUTION)"), 'IS NOT', NULL, 'OR')
->having(DB_SQL::expr("MAX(VP.AMIABILITY)"), 'IS NOT', NULL, 'OR')
->having(DB_SQL::expr("MAX(VP.CLEARNESS)"), 'IS NOT', NULL, 'OR')
->having(DB_SQL::expr("MAX(VP.ATTENTION)"), 'IS NOT', NULL, 'OR')
->having_block(')');
但是如果第一个块给了我一个结果，那么调用第二个块会给我一个与...相关的错误... echm ... translation ??? ......：
ErrorException [ Notice ]: Array to string conversion
SYSPATH/classes/kohana/i18n.php [ 164 ]
return empty($values) ? $string : strtr($string, $values);
我根本无法理解。我想在某些地方出现了语法错误，而构建器无法解决这个问题，但我只能猜测＆amp;谷歌...请帮助我了解这个工作人员的性质......！？
Up：对字符串进行var转储，它正在尝试翻译，并得到错误字符串））：
function __($string, array $values = NULL, $lang = 'en-us')
{
var_dump($string, $values, $lang);die();
.......
return empty($values) ? $string : strtr($string, $values);
}
string(55) "Message: Failed to query SQL statement. Reason: :reason" array(1) { ':reason' => array(5) { [0] => string(5) "00000" [1] => int(0) [2] => string(3276) "(null) [0] (severity 0) [SELECT MAX(VP.ACTIVITY_DT AS [date], MAX(VP.ACTIVITY_TM AS [time], MAX(VP.PHONE_NUM) AS [number], MAX(VP.SERVICE_QUALITY) AS [answer_1], MAX(VP.QUESTION_SOLUTION) AS [answer_2], MAX(VP.RESPONSE_SPEED) AS [answer_3], MAX(VP.AMIABILITY) AS [answer_4], MAX(VP.CLEARNESS) AS [answer_5], MAX(VP.ATTENTION) AS [answer_6], MAX(VP.DESTINATION_NUM) AS [skill], MAX(VP.CALL_ID) AS [call_id] FROM (SELECT [lg].[SessionID] AS [SESSION_ID], CAST(DATEADD(HOUR, 3, lg.MsgTimestamp) AS DATE) AS [ACTIVIT"... [3] => int(0) [4] => int(0) } } string(5) "en-us"
也许有人......我看到这个查询看起来非常棒。应该有“[”＆amp; SQL中的“]”......？
答案 0 :(得分：0)
这是错误：
->from(DB::expr("(".$leap_subquery.")"), 'VP')
应该是：
->from($leap_subquery, 'VP')
并且不执行$leap_subquery
