URL: https://github.com/apache/orc/issues/1022
This question is similar to [THIS one][1] I asked before on StackOverflow,
which after some more trials it works.<br>
Previously there was some issue with the column Id but now I am trying to
filter a column of `DECIMAL` data type but always results give me all the data
instead of the filtered one.
<br><br>
Data which ORC file has in the required columns:<br>
[![enter image description here][2]][2]
And this is how I am trying to filter out the `DECIMAL` column using
`orc::SearchArgument`:
```
orc::RowReaderOptions m_RowReaderOpts;
orc::ReaderOptions m_ReaderOpts;
std::unique_ptr<orc::Reader> m_Reader;
std::unique_ptr<orc::RowReader> m_RowReader;
auto builder = orc::SearchArgumentFactory::newBuilder();
const int snapshot_time_col_id = 22;
orc::Literal ss_begin_time{34080, 14, 9};
orc::Literal ss_end_time{34380, 14, 9};
builder->between(snapshot_time_col_id, orc::PredicateDataType::DECIMAL,
ss_begin_time, ss_end_time);
m_RowReaderOpts.searchArgument(builder->build());
reader = orc::createReader(orc::readFile(a_FilePath.c_str()), m_ReaderOpts);
row_reader = reader->createRowReader(m_RowReaderOpts);
```
<br>
Please give some suggestions on how to filter data of type DECIMAL?
