I want to use Jasypt with Hibernate in servlets. I refered Jasypt here. It says how to configure Hibernate. But, still it is not clear that how I can handle session to save & retrieve results. I did configurations of Hibernate as mentioned in above link(and I m not going to past them here again). Let me know how to save & retrieve data with Session.
For a simple example,lets say, I have a table called 'login' consisting 2 columns 'name','password'. column 'name' data type is varchar and 'password' is varbinary. The pojo class has variables String name and byte[] password. How can I save and retrieve data from table 'login'.At least any useful link which explain with sample codes ll be appreciated.
Edit
When I configured hibernate .hbm file & try to save as usual, an exception is also thrown.

I'm using azure data factory to transform data, I have a derived column to process images.
iif(isNull(column1_images),
iif(isNull(column2_images),
iif(isNull(images),'N/A',toString(images))
,concat(toString(column12_images),' ','(',column2_type,')')),
concat(toString(column1_images),' ','(',column1_type,')'))
when I click on refresh buton I can see the result :
but when I pass this column to the sink I'M GETTING THIS ERROR :
Conversion from StringType to ArrayType(StructType(StructField(url,StringType,true)),false) not defined
can you tell me what is the problem please ?
The error you are getting because there is no Schema designed for the Sink. Hence, you need to use Derived column expression and create a JSON schema to convert the data. Check Building schemas using the expression builder.
You can also check this similar kind of thread for your reference.
I am trying to generate schema from the DataNucleus SchemaTool for a mysql database, that will store countries and states. Here is a sample of that code:
#PersistenceCapable
Public class State{
private String shortCode;
private String fullName;
#Column(allowsNull = "true",name="country_id")
private Country countryId;
}
The following are my schemaGeneration properties:
datanucleus.ConnectionDriverName=com.mysql.jdbc.Driver
datanucleus.ConnectionURL=jdbc:mysql://localhost:3306/geog
datanucleus.ConnectionUserName=geog
datanucleus.ConnectionPassword=geogPass
datanucleus.schema.validateTables=true
datanucleus.mapping.Catalog=geog
datanucleus.mapping.Schema=geog
In my Country class as well, I have a mapping from a Collection, so that the FK reference for States to the Country table is built correctly.
But there is one problem. In the SQL script generated, the Index part has the Schema name as part of the index name itself, which fails the entire script. Here is that piece:
CREATE INDEX `GEOG`.`MST_STATE_N49` ON `GEOG`.`MST_STATE` (`COUNTRY_ID`);
Notice the schema name in the GEOG.MST_STATE_N49 part of the index' name.
I tried setting the schema and catalog name to blank but that yields a ''.MST_STATE_N49 which still fails.
I am using MySQL Server 5.7.17 using the 5.1.42 version of the JDBC driver (yes, not the latest) on Data nucleus JDO 3.1
Any hints on how I can get rid of the schema/catalog name in the generated DDL?
Why are you putting "datanucleus.mapping.Schema" when using MySQL ? MySQL doesnt use schema last I looked. Similarly the "datanucleus.mapping.Catalog" is effectively defined by your URL! MySQL only actually supports JDBC catalog, mapping on to "database", as per this post. Since DataNucleus simply uses the JDBC driver then catalog is the only useful input.
Consequently removal of both schema and catalog properties will DEFAULT to the right place.
After the comment above from Neil Stockton, I commented out both the properties and it worked. Effectively, this is what is needed:
datanucleus.ConnectionDriverName=com.mysql.jdbc.Driver
datanucleus.ConnectionURL=jdbc:mysql://localhost:3306/geog
datanucleus.ConnectionUserName=geog
datanucleus.ConnectionPassword=geogPass
datanucleus.schema.validateTables=true
Hopefully, I can get the answer to the other question (Pt. 2 in my reply-comment above) as well.
I'm working with EntityFramework 5.0 and MySql. I have generated model from database, and my application now have to connect on multiple database with same structred data.
So i have to dynamic change connection string based on some info.
I try to change database name even from config section of connection string, and with EntityConnectionStringBuilder, but i had the same result: my new connection is stored correctly, but data returned are of the first database.
From WebConfig:
add name="dbIncassiEntities" connectionString="metadata=res:///DAL.Modelincassi.csdl|res:///DAL.Modelincassi.ssdl|res://*/DAL.Modelincassi.msl;provider=Devart.Data.MySql;provider connection string="user id=root ... database=dbname2"" providerName="System.Data.EntityClient" />
From code:
EntityConnectionStringBuilder entityBuilder = new EntityConnectionStringBuilder();
entityBuilder.Provider = providerName;
entityBuilder.ProviderConnectionString = "user id=...database=dbname2";
entityBuilder.Metadata = #"res://*/DAL.Modelincassi.csdl|res://*/DAL.Modelincassi.ssdl|res://*/DAL.Modelincassi.msl";
var context = new dbIncassiEntities(entityBuilder.ToString());
My constructor:
public dbIncassiEntities(string conn)
: base(conn)
{
}
What am i missing?
UPDATE
I can see that calling a query directly from SqlQuery, results returned are correct,
while using the generated entities i retrieve wrong data.
var test = context.Database.SqlQuery<string>(
"SELECT cognomenome FROM addetto limit 0,1").ToList();
But calling..
var oAddetto = from c in context.addettoes select c;
So my problem is only on the model itsself, and manually changing the generated schema
<EntitySet Name="addetto" EntityType="dbIncassiModel.Store.addetto" store:Type="Tables" Schema="dbname2" />
..i'll get the right information.
My question now is: how can i change in code these informations??
Any help is really appreciated!!
Thanks, David
Ok, i've found a workaround for now.
I simply clear the shema name on the designer, and now i can call the generated entities succesfully. Hope this can help anyone else.
David
While I could not remove the Schema in the designer, I removed it directly in the .edmx file. Do a full text search for Schema="YourSchema" in an XML editor of your choice and remove the entries. After that, changing the connection string is enough.
Downside is, the Visual Studio designer and mapping explorer won't work properly anymore.
This seems to be more of a dotConnect issue rather than MySQL, since the problem also exists for the Oracle adapter:

Hi there i have some sql tables and i want to convert these in a "Drupal Node Format" but i don't know how to do it. Does someone knows at least which tables i have to write in order to have a full node with all the keys etc. ?
I will give an example :
I have theses Objects :
Anime
field animeID
field animeName
Producer
field producerID
field producerName
AnimeProducers
field animeID
field producerID
I have used the CCK module and i had created in my drupal a new Content Type Anime and a new Data Type Producer that exist in an Anime object.
How can i insert all the data from my simple mysql db into drupal ?
Sorry for the long post , i would like to give you the chance to understand my problem
Thx in advance for your time to read my post
You can use either the Feeds module to import flat CSV files, or there is a module called Migrate that seems promising (albiet pretty intense). Both work on Drupal 6 or 7.
mmmmm.... i think you can export CVS from your sql database and then use
http://drupal.org/project/node_import
to import this cvs data to nodes.....mmmm i don know if there is another non-programmatically way
The main tables for node property data are node and node_revision, have a look at the columns in those and it should be fairly obvious what needs to go in those.
As far as fields go, their storage is predictable so you would be able automate an import (although I don't envy you having to write that!). If your field is called 'field_anime' it's data will live in two tables: field_data_field_anime and field_revision_field_anime which are keyed by the entity ID (in this case node ID), entity type (in the case 'node' itself) and bundle (in this case the name of your node type). You should keep both tables up to date to ensure the revision system functions correctly.
The simplest way to do it though is with PHP and the node API functions:
/* This is for a single node, obviously you'd want to loop through your custom SQL data here */
$node = new stdClass;
$node->type = 'my_type';
$node->title = 'Title';
node_object_prepare($node);
// Fields
$node->field_anime[LANGUAGE_NONE] = array(0 => array('value' => $value_for_field));
$node->field_producer[LANGUAGE_NONE] = array(0 => array('value' => $value_for_field));
// And so on...
// Finally save the node
node_save($node);
If you use this method Drupal will handle a lot of the messy stuff for you (for example updating the taxonomy_index table automatically when adding a taxonomy term field to a node)
Hibernate JPA Template fetches list of objects from database.
Can this be type casted to another class object list??
List<Class1> list1 = (List<Class1>) getJpaTemplate().findByNamedQuery("..someQuery..");
This is the code which i use now. Class1 relates to a table1 in database. Will I be able to fetch the records in table1 into another list<Class2> list2; which has all parameters as table1 and some extra parameters. If I will be able to fetch then will I be able to assign values to those extra parameters through namedQuery ??
Any help appreciated!!
Yes, you can. But before you have some more concrete questions, go read the following:
Hibernate inheritance
and JPA-QL reference, point 7.7, where they explain cat.class
