I want to connect vertica with JDBC. But I got errors.
Here is my code :
....
Class.forName("com.vertica.jdbc.Driver");
....
connection= DriverManager.getConnection
(
"jdbc:vertica://192.168.2.116:5433/schema", "dbadmin", "pass123"
);
But I got this error(if I open the netbeans database section I got same error message. But I connect to vertica with client(Dbeaver)) :
ex = (java.sql.SQLException) java.sql.SQLException: [Vertica]No enum const class com.vertica.dsi.dataengine.utilities.MetadataSourceColumnTag.COLUMN_SİZE
How can I fix this?
So if you need jdbc client for vertica in netbeans or intellij use this vertica jdbc driver. It's the one that worked for me. (taken from dbvisuzlizer).
i think it is because of your locale. in this case turkish i guess.
COLUMN_SİZE has upper case i -> İ
it is verticas fault to use toUpper digressivly.
Vertica's connect string uses databasename, not schema name after the host:port. See the doc for details:
https://my.vertica.com/docs/CE/6.0.1/HTML/index.htm#1395.htm
Connection conn = DriverManager.getConnection(
"jdbc:vertica://VerticaHost:portNumber/databaseName",
"username", "password");
By default, users have a search path of "$user, public, v_catalog, v_monitor and v_internal", therefore, you can create and use a matching username to connect directly to the desired SCHEMA.
Its about 32 bit - 64 bit issue I think, because it is working on 32 bit windows I cant understand
make sure the connector (vertica-jdbc-xxxx.jar) is in the JDK\jre\lib\ext folder

I am converting a FeathersJS system from MySQL to Postgres and facing some problems.
After changing the connection string
"mysql": "mysql://user:password#server:port/database"
to
"postgres": "postgres://user:password#server:port/database"
at config/default.json, I changed the dialect from mysql to pg at feathers/sequelize.js.
But when I started with npm run dev I got the following JSON error message, never seen before.
{
"_bitField":18087936,
"_fulfillmentHandler0":{
"name":"SequelizeConnectionError",
"parent":{
"name":"error",

}
}
After researching a bit with no success, here I am to ask if someone has ever seen this message.
I already tried the dialect as pg and postgres at feathers/sequelize.js, just to check if it would make any difference, but it didn't.
A true beginner error! My fault!
When I created the Postgres (Docker) container, I forgot to create the database itself!
I created the role and gave it the needed permissions, but forgot to create the database corresponding to my connection string.
The Postgres error code mentioned in my question (3D000) corresponds to invalid_catalog_name, i.e., no database corresponding to the connection string.
One may easily check this at Postgres documentation, but I was mistakenly looking for this error code at FeathersJS documentation.
I am new to Hibernate. Using the 5.2.10 FINAL version connecting to Oracle 11g using the Oracle10gDialect with JPA 2.1 and ojdbc8.jar
I try to access a simple stored procedure taking a String input parameter and output a Oracle SYS_REFCURSOR.
StoredProcedureQuery call = session.createStoredProcedureCall("sp_get_profile");
call.registerStoredProcedureParameter(1, String.class, ParameterMode.IN);
call.registerStoredProcedureParameter(2, Class.class, ParameterMode.REF_CURSOR);
call.execute();
An exception occur when I access the function
ERROR SqlExceptionHelper Invalid column type: 2012
DatabaseException::error=[Error registering REF_CURSOR parameter [2]]
I try to write a simple program connecting to DB with the Oracle Driver only. I will have the same error if I register Types.REF_CUSOR as the output parameter to CallableStatement.
cs.registerOutParameter(2, Types.REF_CURSOR);
And the problem can be solved by changing to OracleTypes
cs.registerOutParameter(2, OracleTypes.CURSOR);
Anyone know what is wrong? I need to fall back to use the traditional SQL programming if I cannot get the stored procedure access success. . . please help.
Finally got it work, I should check the Oracle JDBC document first before implementation.
ojdbc8 should be good for Oracle 12c + JDK8 + JPA2.1 with Oracle12cDialect.
For Oracle 11g, need to use ojdbc6.jar
I solved that issue by debugging OJDBC and Hibernate, the building from sources a patched Hibernate CORE library (5.4.15-Final).
I have patched the method ExtractedDatabaseMetaDataImpl.supportsRefCursors which returns always false.
I am trying to connect to DB2 in my local LAN using worklight 6.1.0 and firing a Select Query for lookup of data if exist. But i am getting below error:
{
"errors": [
"Runtime: DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=DATABASE_NAME.REGISTRATION, DRIVER=3.58.82.\nPerformed query:\nSELECT * FROM DATABASE_NAME.registration where DATABASE_NAME.registration.Mob_No = ?"
],
"info": [
],
"isSuccessful": false,
"warnings": [
]
}
My SQL adapter configuration looks like below:
<connectionPolicy xsi:type="sql:SQLConnectionPolicy">
<!-- Example for using a JNDI data source, replace with actual data source name -->
<!-- <dataSourceJNDIName>java:/data-source-jndi-name</dataSourceJNDIName> -->
<!-- Example for using MySQL connector, do not forget to put the MySQL connector library in the project's lib folder -->
<dataSourceDefinition>
<driverClass>com.ibm.db2.jcc.DB2Driver</driverClass>
<url>jdbc:db2://172.21.11.129:50000/MOBILEDB</url>
<user>db2admin</user>
<password>Newuser123</password>
</dataSourceDefinition>
</connectionPolicy>
And js file which has procedure looks like:
var selectStatement1 = "SELECT * FROM DATABASE_NAME.registration where DATABASE_NAME.registration.Mob_No = ?";
var procStmt1 = WL.Server.createSQLStatement(selectStatement1);
function registrationLookup(mobile){
WL.Logger.debug("Inside registrationLookup");
return WL.Server.invokeSQLStatement(
{
preparedStatement : procStmt1,
parameters : [mobile]
}
);
}
I did some Research about connecting DB2 with Worklight and came to know that i need to put below data in worklight.properties file.
wl.db.username=db2admin
wl.db.type=DB2
wl.db.password=Newuser123
wl.db.driver=com.ibm.db2.jcc.DB2Driver
But after adding it, i am not able to deploy Adapter and error says 'db2admin' does not exist. So i have skipped this step in the context of current question. But after going through error which i am getting without adding this worklight.properties data it seems to me that 'Object doesn't exist' as per http://www-01.ibm.com/support/docview.wss?uid=swg21613531 or user table does not exist. Any suggestion would be helpful.
NOTE:
My IP address is 172.21.11.125 from where i am invoking Adapter for DB2.
DB2 instance is running on 172.21.11.129 # 50000.
Already Added db2jcc_license_cu_9.5.jar & db2jcc_9.5.jar in server/lib. It had name appended with '_9.5' which i have removed from both jar and kept only db2jcc_license_cu.jar and db2jcc.jar.
The error message is saying that your SQL statement is invalid, and I therefore infer that your connection to the DB is fine.
To diagnose this first run the SQL using DB2 command line or other tools. My guess is you mean
LARSEN.registration
whereas you are saying DATABASE_NAME.registration
Got Answer to my own Question and its really interesting one. Thanks to https://stackoverflow.com/users/2260967/glen-misquith [Glen Misquith]
Problem was with SQL Query framing which is Different what i did with MYSQL.
Adapter's Java Script file:
var selectStatement4 = "UPDATE \"LARSEN\".\"registration\" SET \"LARSEN\".\"registration\".\"Pass\"=?, \"LARSEN\".\"registration\".\"Re_Pass\"=? WHERE \"User_Name\" = ?";
var procStmt5 = WL.Server.createSQLStatement(selectStatement4);
function updatePassword(username,pass,repass){
WL.Logger.debug("Inside updatePassword "+username+" "+pass+" "+repass);
return WL.Server.invokeSQLStatement(
{
preparedStatement : procStmt5,
parameters : [pass,repass,username]
}
);
}
This is quite a Strange thing Slashes need to be used in SQL Statement while Preparing it.
I would really like to understand this behavior of DB2. And also i cant directly write 'Select * from schema.table_name' and precisely write column name from which data needs to be fetched.
After the sub of the exec JCL, i've got the following error :
SQLCODE = -991
Error = ALL ATTACH WAS UNABLE TO ESTABLISH AN IMPLICIT CONNECT OR OPEN TO DB2
This error is triggered when i call a module that allows to query a table.
PS : i have the necessary privileges for the table.
Thanks.
From IBM's page:
-991 CALL ATTACH WAS UNABLE TO ESTABLISH AN IMPLICIT CONNECT OR OPEN TO DB2. RC1= rc1 RC2= rc2
And some general links for SQL return code information:
http://en.wikipedia.org/wiki/DB2_SQL_return_codes

It is possible you are not running on the same LPAR as DB2 and you don't have sharing enabled.
Ensure you included DSNALI in your program bind (aka link) step, and that you're running on the correct LPAR.
Is there a way to disable the Postgresql translation of messages? I´m running my appl and Postgresql on a pt_BR Windows machine and when a exception is thrown the error message is translated to Portuguese, like:
Caused by: org.postgresql.util.PSQLException: ERRO: relação "unidade_federacao" não existe
Posição: 25
I would like the messages to appear in English.
I´m using the driver postgresql-8.4-701.jdbc3.jar on a Java (with Hibernate) app.
thanks in advance,
Fabrício Lemos
You could change lc_messages in postgresql.conf or just per database:
ALTER DATABASE dbname SET lc_messages=en_us;
See also the manual.
Under Windows, some psql error messages are getting translated corresponding to the format setting in Windows settings -> Clock, Language, and Region -> Change location -> Formats -> Format.
To prevent a mix of translated and untranslated messages, I've set this format to "English (United States)".
execute the following query to your database in order to find the postgres.conf file which is loaded for the configuration:
SHOW config_file;
Edit your postgres.conf file with your prefered lc.... lc_messages,lc_numeric...etc.
i think you can change all with lc_ALL
example : lc_ALL=en_US.UTF-8
Finally execute the following command to reload conf.
SELECT pg_reload_conf();
