Re: Extracting column values from Phoenix composite primary key
Anil,
Phoenix's API is JDBC, so just be aware that you're embarking on usage of
unsupported and mostly undocumented APIs. Not to say they will change, but
they can and might. It'll require you looking at source code, running it in
a debugger, and some trial and error to use these.
For walking through a byte[] row key to get the primary key column values,
use RowKeySchema and in particular the iterator methods. Lots of examples
in the code. You can access the RowKeySchema from PTable which is the
object representation of a table in Phoenix.
For the inverse, building the byte[] of a row key, just use the UPSERT
VALUES statement where you're setting the value of all primary key columns.
Then you can use the PhoenixRuntime.getUncommittedDataIterator() call to
get the List that will be sent to the server (afterward you can
do a connection.rollback()).
HTH. Thanks,
James

Re: Extracting column values from Phoenix composite primary key
Can you please provide the sample rowkey? It is blank in your email below.
Alternatively, an UPSERT VALUES statement I can use to insert a row that I can

HI Michael,
Thank you for the response.
Unfortunately, that is not working.
Following is the snippet. one of the column is unsigned long and trying to
extract the last column (with value target in the below code).
please correct me if i am doing wrong.
byte SEPARATOR_BYTE = 0;
byte[] SEPARATOR_BYTE_ARRAY = { 0 };
byte[] startRow = ByteUtil.concat(

PVarchar.INSTANCE.toBytes("target"));
List cols = new ArrayList();
int j = 0;
for (int i= 0 ; i < startRow.length ; i++){
if (startRow[i] == SEPARATOR_BYTE){
cols.add(Bytes.toString(startRow, j, i-j));
j = i+1;
}
}
cols.add(Bytes.toString(startRow, j, startRow.length - j));
System.out.println(cols.size());

Re: Extracting column values from Phoenix composite primary key
HI Michael,
Table create statement :
CREATE TABLE SAMPLE(TYPE VARCHAR NOT NULL, SOURCE VARCHAR NOT NULL, LABEL
VARCHAR NOT NULL, DIRECTION VARCHAR(10) NOT NULL, REVERSETIME UNSIGNED_LONG
NOT NULL, TARGET VARCHAR,"CF".ID VARCHAR,CONSTRAINT PK PRIMARY
KEY(TYPE,,SOURCE, LABEL, DIRECTION, REVERSETIME, TARGET)) COMPRESSION =

No salt buckets defined.
Smaple table row key -
byte[] startRow = ByteUtil.concat(PVarchar.INSTANCE.toBytes("test"),
QueryConstants.SEPARATOR_BYTE_ARRAY,
PVarchar.INSTANCE.toBytes("src"),

PUnsignedLong.INSTANCE.toBytes(1235464603853L),
PVarchar.INSTANCE.toBytes("target"));
i am trying to extract TARGET column. Thanks.

Re: Extracting column values from Phoenix composite primary key
Can you provide an example of one of the rowkeys, the values you are expecting
out of it, and the full table definition? Of importance in the table definition
will be whether you have salt buckets defined.

If you split the rowkey on the zero byte character, you should end up with the
individual columns that made up your primary key. Details are here:-

Anil If you split the rowkey on the zero byte character, you should end up with the individual columns that made up your primary key.
