如何从雪花表中替换字符串

Question

我有一个雪花表作为 TEST_TABLE

SOURCE_RECORD_ID                                 COL_A  COL_B COL_C
paragon_altdata:model:2021-04-29_003108:1          A     A     A
paragon_altdata:model:2021-04-29_003108:2          A     A     A
paragon_altdata:model:2021-04-29_003108:3          A     A     A
paragon_altdata:model:2021-04-29_003108:4          A     A     A
paragon_altdata:model:2021-04-29_003108:5          A     A     A
paragon_altdata:model:2021-04-29_003108:6          A     A     A
paragon_altdata:model:2021-04-29_003108:7          A     A     A
paragon_altdata:model:2021-04-29_003108:8          A     A     A
paragon_altdata:model:2021-04-29_003108:9          A     A     A

在此表中，我想将第一列中的部分字符串 paragon_altdata 替换为 paragonintel_altdata

我的表格应该如下所示

SOURCE_RECORD_ID                                 COL_A  COL_B COL_C
paragonintel_altdata:model:2021-04-29_003108:1         A     A     A
paragonintel_altdata:model:2021-04-29_003108:2         A     A     A
paragonintel_altdata:model:2021-04-29_003108:3         A     A     A
paragonintel_altdata:model:2021-04-29_003108:4         A     A     A
paragonintel_altdata:model:2021-04-29_003108:5         A     A     A
paragonintel_altdata:model:2021-04-29_003108:6         A     A     A
paragonintel_altdata:model:2021-04-29_003108:7         A     A     A
paragonintel_altdata:model:2021-04-29_003108:8         A     A     A
paragonintel_altdata:model:2021-04-29_003108:9         A     A     A

请任何人帮助我解决这个问题

Answer 1

你可以只使用replace，然后创建一个新表做一个create table as select

create NEW_TABLE as 
select 
     replace(SOURCE_RECORD_ID, 'paragon_', 'paragonintel_') as SOURCE_RECORD_ID
    ,COL_A
    ,COL_B
    ,COL_C
from TEST_TABLE
;

然后您可以交换它们并删除旧的。
