fix: 处理自关联查询时，对Table:alias的写法sql表名拼写异常的问题

[zxcwindy]

针对以下查询

{
  "[]":{
    "join":"&/Table:b/pid@",
    "Table:a":{
      "colId":"297e77a2623ce59401623ce740d90000",
      "@column":"colId,createTime"
    },
    "Table:b":{
      "@column":"colId,colCode,colName,pid",
      "pid@":"/Table:a/colId"
    }
  }
}

解决拼接的sql中表名为 "Table:a"，导致sql查询异常的问题
