請提供更多的背景; 'sadique.electric.selcoBrand.initComponents（selcoBrand.java:33）'（我認爲是你的代碼）究竟發生了什麼，你想做什麼，到目前爲止你嘗試過什麼，等等。簡單地發佈堆棧跟蹤沒有其他的背景就像是當你只說「我聽到一種噪音」時，期待你的機械師修理你的車。 – dimo414

閱讀該消息... y原因存在... –

MySQLSyntaxErrorException：您的SQL語法中有錯誤;檢查與你的MariaDB服務器版本相對應的手冊，在第1行'-brand'附近使用正確的語法錯誤代碼：1064調用：SELECT id，amps，comingA，comingB，g1，gTotal，hp，model，mr，newOrderA ，newOrderB，totalImport FROM clientdb.selco-brand查詢： –

在本節

... FROM clientdb.selco-brand

表名selco-brand包含一個連字符，所以表的名稱必須使用反引號被引用：

... FROM clientdb.`selco-brand`
