cassandra-jdbc-wrapper's Issues

CHAR_OCTET_LENGTH null as default value results in exception

Hi Alexander,
I am on the branch 3.0.3-spanshot which fixes the previous bug. However, I have found that that in MetadataResultSets: 170 there is the definition for charol as follows

//CHAR_OCTET_LENGTH
Integer charol = null;
if (jtype instanceof JdbcAscii || jtype instanceof JdbcUTF8) charol = Integer.MAX_VALUE;

and for those datatype that are not defined (i.e. JdbcDate), when trying to create column based on retrieved metadata, results in the following exception

Caused by: java.lang.NumberFormatException: For input string: "null"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) ~[na:1.8.0_91]

at liquibase.snapshot.jvm.ColumnSnapshotGenerator.addTo(ColumnSnapshotGenerator.java:111) ~[liquibase-core-3.4.1.jar:na]

My workaround was just to set it up by default to max_value (is that wrong?) and it worked

Integer charol = Integer.MAX_VALUE;

Cheers,

Can this support joins

Hi We have a requirement , where we need to use joins and group by funcitons, will this provide support for joins and Group by.

Codec Not found Exception

When we try to insert a SQL Date into date type column in cassandra, it is throwing Codec not found exception.

What would be the right way to use it ? @adejanovski

CodecNotFoundException for bigInt to Long

Select a bigint type column from Cassandra in RJDBC gives this error:
Error in .jcall(rp,"I","fetch",stride,block):

How would i go about creating a Custom Codec ?

Specifying socket options

Hello,
I am using Cassandra 3 cluster (5 machines) and 3.1.0 version of your driver.
It seems that we cannot specify other values for socket options, because in SessionHolder I see only next:
builder.withSocketOptions(new SocketOptions().setKeepAlive(true));

Can we somehow get new version with possibility to specify:

1. connectTimeoutMillis
2. readTimeoutMillis
3. tcpNoDelay

Thanks in advance.

It does not work with SparkSession.read().jdbc() since CQL does not support "where 1=0" syntax

Please see the real issue after the comment below.

Is it possible to connect to Azure Cassandra?

Is it possible to connect to Azure Cassandra with this driver?

And how do I connect via SSL? It's possible?

Thanks.

CodecNotFoundException: Codec not found for requested operation: [varint <-> java.lang.Integer]

Hi, I've been studing the cassandra a little, and have found a possible issue.

• DBeaver (currently v6.3.5)
• cassandra-jdbc-wrapper v3.1.0
• [cqlsh 5.0.1 | Cassandra 3.11.5 | CQL spec 3.4.4 | Native protocol v4]

I've followed this tutorial.
Columns emp_phone and emp_sal are of "varint" data type.
Data inserted as mentioned on the tutorial.
Following simple select * from emp;, in the GUI i'm seeing following error (while in the cqlsh the select works well):

Missing implementation of getObject(String, Class<T>) method in CassandraResultSet

Assuming I execute a select query like this one:

SELECT id, ts_update FROM mytable ;

where ts_update is a timestamp.

I used the Cassandra JDBC wrapper with MyBatis 3.4.6. My column ts_update is mapped on field of type OffsetDateTime in a Java bean.

In this version of MyBatis, the mapping of the columns of type timestamp was implemented as following:

public OffsetDateTime getNullableResult(ResultSet rs, String columnName) throws SQLException {
        Timestamp timestamp = rs.getTimestamp(columnName);
        return getOffsetDateTime(timestamp);
}

So, it worked with the current version of CassandraResultSet (3.1.0). But, when I updated MyBatis to the version 3.5.1, I got the following error:

Caused by: java.sql.SQLFeatureNotSupportedException: the Cassandra implementation does not support this method
	at com.github.adejanovski.cassandra.jdbc.AbstractResultSet.getObject(AbstractResultSet.java:136)

	at org.apache.ibatis.type.BaseTypeHandler.getResult(BaseTypeHandler.java:81)
	at org.apache.ibatis.executor.resultset.DefaultResultSetHandler.getPropertyMappingValue(DefaultResultSetHandler.java:472)

The issue comes from the fact that the method getObject(String, Class<T>) is not implemented in CassandraResultSet but called by the new implementation of the OffsetDateTime handling:

public OffsetDateTime getNullableResult(ResultSet rs, String columnName) throws SQLException {
        return (OffsetDateTime)rs.getObject(columnName, OffsetDateTime.class); 
}

So, the mentioned method should be implemented.

Does not seem to work on Cassandra 3

Hello.
We receive an error message: "unconfigured table schema_keyspaces" when trying to connect to cassandra. (we can connect with an older jdbc driver over rpc, without any problems, so there are no problems on the Cassandra side.)

Do you have any plans to support Cassandra 3?
If thats the case, -whats the time frame?

CodecNotFoundException

I'm using this driver with RJDBC (https://cran.r-project.org/web/packages/RJDBC/index.html), and am able to successfully connect to my local Cassandra instance and retrieve a list of tables. When I try to run a query, I get

com.datastax.driver.core.exceptions.CodecNotFoundException: Codec not found for requested operation: [int <-> java.lang.Double]

CodecNotFoundException because an off-by-one error

When calling method com.github.adejanovski.cassandra.jdbc.CassandraResultSet#getTimestamp(int, java.util.Calendar) I get a CodecNotFoundException.

This error is caused because this method delegates to com.github.adejanovski.cassandra.jdbc.CassandraResultSet#getTimestamp(int) passing a wrong value in the index parameter.

public Timestamp getTimestamp(int index) throws SQLException {
    this.checkIndex(index);
    java.util.Date date = this.currentRow.getTimestamp(index - 1);
    return date == null?null:new Timestamp(this.currentRow.getTimestamp(index - 1).getTime());
}

public Timestamp getTimestamp(int index, Calendar calendar) throws SQLException {
    this.checkIndex(index);
    java.util.Date date = this.currentRow.getTimestamp(index - 1);
    return date == null?null:this.getTimestamp(index - 1);
}

If the method getTimestamp(int, java.util.Calendar) receives 2 in the index param, it would then call getTimestamp(int) with index - 1. This causes the call to this.currentRow.getTimestamp(index - 1) being done over the previous column, not the current one.

NPE on make columns

Hi Alexander,

I am trying to put in action liquibase on Cassandra using your JDBC wrapper and I receive following NPE while trying to create an snapshot for a table

Caused by: java.lang.NullPointerException

It seems that the statement looses the connection anywhere.

Thanks in advance for your answer,

PreparedStatment getParameterMetaData()

Collection of frozen types support

Hi,
I'm trying to query C* 3.7 with your driver but my column family (table) model contains a list of frozen tuple of strings and the driver don't support it. Like this cql example :

CREATE TABLE IF NOT EXISTS test.users(
  user_id uuid,
  time timeuuid,

  created_at date STATIC,

  info map<text, text>,
  ancestors list<frozen<tuple<text,text>>>,
  childs list<frozen<tuple<text,text>>>

I don't know how to build a jdbc driver but do you know if this type is easy to handle? How could I fix (update) your driver to do the job ?
Thanks !

Error in .jcall(rp, "I", "fetch", stride, block) :
com.datastax.driver.core.exceptions.CodecNotFoundException: Codec not found for requested operation: [frozen<tuple<varchar, varchar>> <-> java.lang.String]

CassandraResultSet getObject method did not handle null value for Timestamp type.

Hi Alexander,

I am using your JDBC wrapper for Cassandra JDBC data Operator and I receive following NPE while trying to get ResultSet from a table where contain a TimeStamp column.

Seems you do not handle the null value exception if the type is Timestamp:

else if (typeName.equals("timestamp")){
return (Object) new Timestamp((currentRow.getTimestamp(index-1)).getTime());

Thanks in advance for your answer.

True on CassandraStatement#execute when inserting

Hey,
I was trying to use the jdbc wrapper to batch insert(using batch update of Spring's JdbcTemplate).
It is basically an array of sql insert statements(strings)..
Now, what happens, is that the check that is done to see if these update statements are valid is if the CassandraStatement#execute function returns true.. Now this happens because the only check that is done this is "this.currentResultSet != null" while it is not null(but the "this.currentResultSet.hasMoreRows()" immediately returns false(so there are no rows returned in this result set..
When it returns true, the JdbcTemplate of Spring throws an exception of it being an invalid batch SQL statement..
The only thing needed is turn this row into "this.currentResultSet != null && this.currentResultSet.hasMoreRows()" or any equivalent ..
Thanks :)

EDIT:
Also, when opening a connection, it prints "Datacenter: %s; Host: %s; Rack: %s"(forgotten String.fomrat())..
