用sql查詢的時候出現這個錯誤
com.alibaba.druid.sql.parser.ParserException: Error : LBRACKET
at com.alibaba.druid.sql.parser.SQLParser.as(SQLParser.java:87)
at com.alibaba.druid.sql.parser.SQLSelectParser.parseSelectList(SQLSelectParser.java:206)
at com.alibaba.druid.sql.dialect.sqlserver.parser 追蹤原始碼 , 發現這個異常在此處丟擲
throw new ParserException("Error : " + lexer.token());這個token是一個列舉裡面有很多的sql關鍵字

}我找了一下LBRACKET , 發現是 [ 這個符號 , 查看了mybaits的xml , 修改了這個相關的問題 , 問題解決 .
如果到時候出現類似的問題 , 檢視一下這個列舉的對應 , 可以快速排查定位到問題 .
