Delete Table Column的意思|示意

A customer wants to delete large amounts of data on other dimensions than time (which is the column that the table is data partitioned on).

客户想删除除时间维(表是在这一列上进行数据分区的)以外的其他维上的大量数据。

If you are using a condensed CCD table, when processing a delete, the existing row is updated and the IBMQREP_OPERATION column is set to 'd'.

如果您在使用一个压缩ccd表，那么在处理delete操作时，现有的行将被更新，而ibmqrep_operation列将被设为‘d’。

In addition, the check boxes next to the column names in the rectangle representing the table or table-valued object are removed because you cannot specify individual columns to delete.

此外，因为无法指定要删除的单个列，所以在代表表或表值对象的矩形中，列名旁边的复选框已被移除。
