HY，
我正在寻找一种使用PostgreSQL直接从数据库查询我的VOIP信息的方法。 VOIP服务是CEL（每个事件的行）Asterisk。 我的数据库如下所示：
|Field name | Value/Example | Notes
|eventtype | CHAN_START | The name of the event. The list of events that may occur can be found in Table 24.7, “CEL event types”.
|eventtime | 2010-08-19 07:27:19 | The time that the event occurred.
|cidname | Julie Bryant | The caller ID name set on the channel associated with this event.
|cidnum | 18435551212 | The caller ID number set on the channel associated with this event.
|cidani | 18435551212 | The Automatic Number Identification (ANI) number set on the channel associated with this event.
|cidrdnis | 18435551234 | The redirecting number set on the channel associated with this event.
|ciddnid | 18435550987 | The dialed number set on the channel associated with this event.
|exten | 101 | The extension in the dialplan that is currently being executed.
|context | LocalSets | The context for the extension in the dialplan that is currently being executed.
|channame | SIP/0004F2060EB4-00000010| The name of the channel associated with this event.
|appname | Dial | The name of the dialplan application currently being executed.
|appdata | SIP/0004F2060E55 | The arguments that were passed to the dialplan application that is currently being executed.
|amaflags | DOCUMENTATION | The Automatic Message Accounting (AMA) flag associated with this call. This may be one of the following: OMIT, BILLING, DOCUMENTATION, or Unknown.
|accountcode | 1234 | An account ID. This field is user-defined and is empty by default.
|uniqueid | 1282218999.18 | The unique ID for the channel that is associated with this event.
|userfield | I like waffles! | User-defined event content.
|linkedid | 1282218999.18 | The per-call ID. This ID helps tie together multiple events from multiple channels that are all a part of the same logical call. The ID comes from the uniqueid of the first channel in the call.
|peer | SIP/0004F2060E55-00000020| The name of the channel bridged to the channel identified by channame.
我希望得到今天约会的所有电话。我尝试了流动：
--COMPLETE PHONECALL
SELECT T.ID, T.EVENTTYPE, T.EVENTTIME, T.CID_NAME, T.CID_NUM, T.CID_ANI, T.CID_DNID, T.CID_RDNIS, T.EXTEN, T.CONTEXT, T.CHANNAME,
T.APPNAME, T.APPDATA, T.AMAFLAGS, T.ACCOUNTCODE, T.PEERACCOUNT, T.UNIQUEID, T.LINKEDID
FROM PUBLIC.CEL T
WHERE LINKEDID IN (
SELECT LINKEDID
FROM PUBLIC.CEL T1
WHERE DATE(T1.EVENTTIME) = (SELECT MAX(DATE(EVENTTIME)-1) FROM PUBLIC.CEL)
AND EVENTTYPE = 'CHAN_START'
AND CID_NUM NOT LIKE '20%'
AND EXISTS(
SELECT *
FROM PUBLIC.CEL T2
WHERE 1=1 --DATE(T2.EVENTTIME) = (SELECT MAX(DATE(EVENTTIME)) FROM PUBLIC.CEL)
AND EVENTTYPE = 'APP_START'
AND T1.ID < T2.ID
AND T1.UNIQUEID = T2.UNIQUEID
AND EXISTS(
SELECT *
FROM PUBLIC.CEL T3
WHERE 1=1 --DATE(T3.EVENTTIME) = (SELECT MAX(DATE(EVENTTIME)) FROM PUBLIC.CEL)
AND EVENTTYPE = 'ANSWER'
AND T2.ID < T3.ID
AND T2.UNIQUEID = T3.UNIQUEID
AND EXISTS(
SELECT *
FROM PUBLIC.CEL T4
WHERE 1=1 --DATE(T4.EVENTTIME) = (SELECT MAX(DATE(EVENTTIME)) FROM PUBLIC.CEL)
AND EVENTTYPE = 'HANGUP'
AND T3.ID < T4.ID
AND T3.UNIQUEID = T4.UNIQUEID
AND EXISTS(
SELECT *
FROM PUBLIC.CEL T5
WHERE 1=1 --DATE(T5.EVENTTIME) = (SELECT MAX(DATE(EVENTTIME)) FROM PUBLIC.CEL)
AND EVENTTYPE = 'CHAN_END'
AND T4.ID < T5.ID
AND T4.UNIQUEID = T5.UNIQUEID
)
)
)
)
GROUP BY T1.LINKEDID
ORDER BY T1.LINKEDID ASC
)
ORDER BY T.LINKEDID ASC
但那没用！ 我尝试的另一件事是：
SELECT *
FROM PUBLIC.CEL
DATE(EVENTTIME) = (SELECT MAX(DATE(EVENTTIME))
然后我用birt来过滤所需的输出..这没有给我所需的输出。
是否有一些关于如何使用SQL查询CEL数据库的文档？ 我不想使用像'Asternic'这样的工具
由于
PS。 这是一个解释CEL'表'数据库的链接 http://www.asteriskdocs.org/en/3rd_Edition/asterisk-book-html-chunk/Monitoring_id246945.html#Monitoring_id255410
答案 0 :(得分：0)
如果您只想要当天回答的电话，请执行以下操作：
select * from cel WHERE eventtype = 'ANSWER' and eventtime > curdate() limit 1 GROUP BY linkedid;
但我认为你还有更多信息要找？你能澄清一下你究竟在寻找什么吗？您是否正在寻找所有接听电话的时间长度？或者你只是想要接听电话的所有活动？
要获取接听电话的所有活动，您可以尝试以下方式：
SELECT * FROM cel WHERE eventtime > curdate() and linkedid IN (select DISTINCT linkedid from cel WHERE eventtype = 'ANSWER' and eventtime > curdate());
请在评论中准确告诉我您尝试获取哪些信息，并且我会看到我能提出的信息。
