Exampleâ
The data read from source is a table like this:
id | name | age | card |
---|---|---|---|
1 | Joy Ding | 20 | 123 |
2 | May Ding | 20 | 123 |
3 | Kin Dom | 20 | 123 |
4 | Joy Dom | 20 | 123 |
We want to delete age
field and update the filed order to id
, card
, name
and rename name
to new_name
. We can add FieldMapper
transform like this
transform {
FieldMapper {
source_table_name = "fake"
result_table_name = "fake1"
field_mapper = {
id = id
card = card
name = new_name
}
}
}
Then the data in result table fake1
will like this
id | card | new_name |
---|---|---|
1 | 123 | Joy Ding |
2 | 123 | May Ding |
3 | 123 | Kin Dom |
4 | 123 | Joy Dom |
