请参阅下面的测试案例，以显示文件排除/包含，使用模式 -
文件上传到名为-ock_data.csv-
复制到 @sf_s3_stage模式='。*/mock_data。*';*';更改了文件名并添加了一个前缀，以beproding -copying -repoying -
code> code> list @sf_s3_stage @sf_s3_stage;尝试复制 -
@sf_s3_stage pattern ='。*/mock_data。
从上面可以看出，没有文件复制。
模式
Refer below test-case, to show file exclusion/inclusion, using pattern -
To upload file named - MOCK_DATA.csv -
copy into mock_data_tab from @sf_s3_stage pattern='.*/MOCK_DATA.*';Changed file name and added a prefix, to test exclusion from copying -
list @sf_s3_stage;Trying to copy -
copy into mock_data_tab from @sf_s3_stage pattern='.*/MOCK_DATA.*';As can be seen from above no file gets copied.
If we use pattern .* as prefix it will pick all (not desired) -
copy into mock_data_tab from @sf_s3_stage pattern='.*MOCK_DATA.*';
