如果模板字符串为空，如何删除？

Question

我想使用JavaScript模板字符串创建MySQL查询。 我只想查询不为空的列

我不知道该怎么做

var payload= {
        id: 255,
        color : this.editedItem.color,
        state : this.editedItem.state,
        pir   : this.editedItem.pir,
        override: this.editedItem.override,
        };

var topic=`INSERT INTO sensors_tbl (sensor_id,s_color,s_state,s_pir,s_override,last_checked)
          VALUES (${payload.id},"${payload.color}","${payload.state}","${payload.pir}","${payload.override}",NOW());`;

例如，如果payload.state=""我想从查询中将其删除。 谢谢。
