# Drop field

在执行脚本期间，可以使用 drop field 语句随时从数据模型和内存中删除一个或多个 Qlik Sense 字段。表的 "distinct" 属性在 drop field 语句之后被删除。

信息注释drop field 和 drop fields 都是允许的格式，效果完全一样。 如果未指定任何表格，字段将从全部表格中删除。

语法：

Drop field fieldname { , fieldname2 ...} [from tablename1 { , tablename2 ...}]

Drop fields fieldname { , fieldname2 ...} [from tablename1 { , tablename2 ...}]

示例：

`Drop 
 field A;` `Drop 
 fields A,B;` `Drop 
 field A from X;` `Drop 
 fields A,B from X,Y;`
