Metabase Filters示例

Question

我正在使用与Mysql集成的配置数据库来进行报告。我浏览了文档，但无法找到任何解释如何在基于SQL的问题中实现过滤器的示例。

我发现的唯一例子是关于日期范围和字段过滤器，而不是文本和数字。

任何人都可以提供有关如何使用文本过滤器的文档或任何示例。

我正在使用配置数据库版本v0.24.2

我正在尝试运行的查询是

 SELECT  @a:=@a+1 "Serial Number", ssk_transaction.transactionId AS "TranId",   
t2.typeName AS "Transaction Type",  
ssk_transaction.createdTime AS "GenDate", t3.deviceName AS "Machine Name",  
 t3.deviceLocation AS "Machine Location", t9.eventApiName AS 'API Name' ,  
t8.vendorResultCode AS 'Last API Response',  
(SELECT createdTime FROM ssk_transaction_event_detail t4 WHERE t4.transactionId  
 = ssk_transaction.transactionId ORDER BY id DESC LIMIT 1) AS "Last API Called",  
(SELECT IFNULL(SUM(t5.itemName * t4.itemCount), 0) FROM  
 ssk_transaction_cash_detail t4  
LEFT JOIN ssk_inventory_item t5 ON (t4.itemId = t5.itemId)  
LEFT JOIN ssk_inventory_category t10 ON (t5.categoryId = t10.categoryId)  
WHERE t4.transactionId = ssk_transaction.transactionId AND t10.categoryName =   'acceptor') "Cash In",  
(SELECT IFNULL(SUM(t5.itemName * t4.itemCount), 0) FROM       ssk_transaction_cash_detail t4  
LEFT JOIN ssk_inventory_item t5 ON (t4.itemId = t5.itemId)  
LEFT JOIN ssk_inventory_category t10 ON (t5.categoryId = t10.categoryId)  
WHERE t4.transactionId = ssk_transaction.transactionId AND t10.categoryName =   'dispenser') "Cash Returned",  
IFNULL((SELECT "Cash In"), 0) - IFNULL((SELECT "Cash Returned"), 0) AS "Amount   of Activity",  
(SELECT t8.vendorResultCode FROM ssk_transaction_event_detail t8 WHERE       t8.transactionId = ssk_transaction.transactionId AND t8.eventId = 6 ORDER BY id       DESC LIMIT 1) AS "Sim Status",  
'Completed' AS "Transaction Status",  
ssk_transaction.customerMsisdn AS MSISDN,  
ssk_transaction.customerCNIC AS CNIC  
FROM  (SELECT @a:=0) initvars, ssk_transaction  
LEFT JOIN ssk_transaction_type t2 ON (ssk_transaction.typeId = t2.typeId)  
LEFT JOIN ssk_device t3 ON (ssk_transaction.deviceUUID = t3.deviceUUID)  
LEFT JOIN ssk_transaction_cash_detail t6 ON (ssk_transaction.transactionId =       t6.transactionId )  
LEFT JOIN ssk_inventory_item t7 ON (t6.itemId = t7.itemId)  
LEFT JOIN ssk_transaction_event_detail t8 ON (ssk_transaction.transactionId =   t8.transactionId AND t8.eventId = 10)  
LEFT JOIN ssk_transaction_event t9 ON (t9.eventId = t8.eventId)  
WHERE {{created_at}} AND {{id}} [[AND ssk_transaction.customerMsisdn=       {{msisdn}}]] AND {{cnic}} and  t2.typeId = 3 AND t8.eventId = 10 AND       t8.vendorResultCode = '405000000'  
GROUP BY ssk_transaction.transactionId  
ORDER BY ssk_transaction.createdTime ASC  

Answer 1

在您正在使用的版本号下的 github 页面上打开一个问题。 贡献者将帮助您查询或甚至提供所需的文档/ wiki。

也许这可以帮到你：

try to use CONCAT('%',{{variable}},'%') such as:

WHERE 1=1 [[ AND test LIKE CONCAT('%',{{variable}},'%') ]]

Answer 2

要创建变量，只需编写查询并以{{variablename}}格式为变量定义占位符，当您执行此操作时，Metabase将自动显示右侧的“变量”面板，您必须选择此变量的类型（如果提供默认值，也可以根据需要标记变量。）

您不应该在查询中转义变量占位符（这就是为什么CONCAT（＆＃39;％＆＃39;，{{variable}}，＆＃39;％＆＃39;）不起作用的原因）您可以使用双括号将整个表达式标记为可选项。

下面的图片给出了一个查询示例：

  

从pg_tables中选择*，其中schemaname = {{schemaname}} [[and tablename = {{tablename}}]]

在此示例中，如果您没有为tablename变量提供值，则将忽略整个tablename过滤器。请注意，两个变量都标有文本类型。

Answer 3

要在基于sql的（本机查询）问题上添加过滤器，请在生成sql结果后，单击右下角的罗盘，然后单击“分析此查询的结果”。过滤器选项将显示在顶部。

然后您可以将其另存为其他问题，以便始终显示过滤器屏幕。
