# Drop field

透過 QlikView 陳述式，可以隨時在指令碼執行期間，從資料模型和記憶體捨棄一或數個 drop field 欄位。在 drop field 陳述式後移除表格的「相異」屬性。

資訊備註drop field 和 drop fields 兩者均可，效果並無不同。 如果未指定表格，將從出現欄位的所有表格中捨棄欄位。

語法：

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

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

範例：

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