Dynamic change queries.

gritsay

When i can read from database data via dynamically changing queries?
For example:
table in source database:

name | date      | param2 |param3|
id1    | 1.02.10  | test1    |test2 |
id2    |  2.02.10 | test2    |test2 |   

I need for one iterate extract data from 01.02.10 date

1 Iterate processing:
id1    1.02.10  test1    test2

and i need for two iterate extract data from 02.02.10 

2 Iterate processing:
id2    2.02.10  test2    test2

What operators i should use for this iterate processing?

Hi,
there are several loop operators in RapidMiner. In combination with Macros which can be included into the search query of a Read Database operator. This is a powerful approach for dynamic queries. Please take a look into the Manual to get familiar with Macros.
