I was trying to work with Oracle Database from Haskell and have faced with such problem.
So, there is this code.
module Main where
import Database.HDBC
import Database.HDBC.ODBC
main :: IO ()
main = do
let connectionString = "Driver={Microsoft ODBC for Oracle};Server=127.0.0.1;Uid=valera;Pwd=2562525;"
let ioconn = connectODBC connectionString
conn <- ioconn
vals <- quickQuery conn "SELECT * FROM PERSONS_TEST" []
print vals
return ()
Pretty simple, huh? But that won't work. With this connection string the error is
*** Exception: SqlError {seState = "[\"HY090\"]", seNativeError = -1, seErrorMsg = "sqlGetInfo SQL_TXN_CAPABLE: [\"0: [Microsoft][ODBC driver for Oracle]\\65533...
and then 65333 repeats many times. And with this
Provider=msdaora;Data Source=127.0.0.1;User Id=valera;Password=2562525;
the error is
*** Exception: SqlError {seState = "[\"IM002\"]", seNativeError = -1, seErrorMsg = "connectODBC/sqlDriverConnect: [\"0: [Microsoft][\\65533...
and 65333 repeats again till the end
I suppose, that the problem is in connection string, but I had tried a whole bunch of them (I've used http://www.connectionstrings.com/)
I'm using Haskell Platform 2011.4.0.0, GHC 7.0.4, Oracle Database XE 11.2 on Windows 7 64-bit. Microsoft MDAC SDK installed.
\65533 and so on is the symbols of ODBC driver error message string in your locale (RU?). I find the best way so on to develop in english locale system, thus error messages in ghci console shown in english language and can be read.

I try to make a connection between pyspark and oracle sql, so I could load tables in this way;
I am using the following code:
from pyspark import SparkConf, SparkContext
from pyspark.sql import SQLContext, Row
import os
spark_config = SparkConf().setMaster("local").setAppName("Project_SQL")
sc = SparkContext(conf = spark_config)
sqlctx = SQLContext(sc)
os.environ['SPARK_CLASSPATH'] = "C:\Program Files (x86)\Oracle\SQL Developer 4.0.1\jdbc\lib.jdbc6.jar"
df = sqlctx.read.format("jdbc").options(url="jdbc:oracle:thin:#<>:<>:<>"
, driver = "oracle.jdbc.driver.OracleDriver"
, dbtable = "account"
, user="...."
, password="...").load()
But I get the following error.
An error occurred while calling o29.load.:
java.sql.SQLRecoverableException: IO Error: The Network Adapter could not establish the connection
Could anyone help me to fix this? Do you think it is because of the firewall?
We have a very simple Java code which executes an Oracle stored procedure using CallableStatement API. An Oracle stored procedure doesn't have an OUTPUT parameter defined, however in the Java Code we are trying to register an OUT parameter and retrieve it :
cs = cnDBCon.prepareCall("{call "+strStoredProcedureName+ "}");
cs.registerOutParameter(1, Types.NUMERIC);
cs.execute();
int isOk = cs.getInt(1);
According to Java API ( https://docs.oracle.com/javase/8/docs/api/java/sql/CallableStatement.html#getInt-int- ) when a return value is SQL NULL, the result is 0.
It worked perfectly fine when we were running on Java7/WebLogic 12.1.3. Since we switched to Java8/WebLogic 12.2.1 we started to get the error :
java.sql.SQLException: Missing defines
at oracle.jdbc.driver.Accessor.isNull(Accessor.java:744)
at oracle.jdbc.driver.NumberCommonAccessor.getInt(NumberCommonAccessor.java:73)
at oracle.jdbc.driver.OracleCallableStatement.getInt(OracleCallableStatement.java:1815)
at oracle.jdbc.driver.OracleCallableStatementWrapper.getInt(OracleCallableStatementWrapper.java:780)
at weblogic.jdbc.wrapper.CallableStatement_oracle_jdbc_driver_OracleCallableStatementWrapper.getInt(Unknown Source)
The obvious choice is to update the stored procedure or java code, but I am wondering about the reason the behavior changed. Is it a more strict JDBC driver?
I try openning a .mdb file using CDaoDatabase, but at Open() catches an error: Unrecognised database format. I created the database first in MSAcces2007 and saved the file as .mdb, then i installed MSAcces2003 and created the file again, but there's the same error. Does anyone have a clue what's happening?
CString pathDB = "SMACDB\\Transports.mdb";
CDaoDatabase dbTransp;
try
{
dbTransp.Open(pathDB);
CDaoRecordset rs(&dbTransp);
COleVariant var1;
rs.Open(dbOpenSnapshot, "SELECT * FROM Transporturi");
while (!rs.IsEOF())
{
var1 = rs.GetFieldValue(1);
CString val = (LPCTSTR)var1.bstrVal;
g_carRestrict.pCarNmb.AddTail(val);
var1 = rs.GetFieldValue(2);
g_carRestrict.pAllowed.AddTail(var1.lVal);
rs.MoveNext();
}
rs.Close();
dbTransp.Close();
}
catch (CDaoException *pEx)
{
pEx->Delete();
}
Visual C++ 6 uses DAO 3.5 by default which does not support Access 2000 or later formats. To have MFC uses DAO 3.6, change the runtime version number to 6.01.

You receive an "Unrecognized database format" error message when you open a database created with Access 2000
When I am trying to upload an Image using below code, I am getting following error : java.sql.SQLException: ORA-01460: unimplemented or unreasonable conversion requested
File image = new File("D:/"+fileName);
preparedStatement = connection.prepareStatement(query);
preparedStatement.setString(1,"Ayush");
fis = new FileInputStream(image);
preparedStatement.setBinaryStream(2, (InputStream)fis, (int)(image.length()));
int s = preparedStatement.executeUpdate();
if(s>0) {
System.out.println("Uploaded successfully !");
flag = true;
}
else {
System.out.println("unsucessfull to upload image.");
flag = false;
}
Please help me out.
DB Script :
CREATE TABLE ESTMT_SAVE_IMAGE
(
NAME VARCHAR2(50),
IMAGE BLOB
)
Its first cause is incompatible conversion but after seeing your DB script, I assume that you are not doing any conversion in your script.
There are other reported causes of the ORA-01460 as well:
Incompatible character sets can cause an ORA-01460
Using SQL Developer, attempting to pass a string to a bind variable value in excess of 4000 bytes can result in an ORA-01460
With ODP, users moving from the 10.2 client and 10.2 ODP to the 11.1 client and 11.1.0.6.10 ODP reported an ORA-01460 error. This was a bug that should be fixed by patching ODP to the most recent version.

I am trying to connect to an Oracle database from R.
I used RODM_open_dbms_connection(dsn, uid = "", pwd = ""), but it doesn't work. I am not sure what kind of the error it is.
Here is the error screen from R.
> library(RODM) Loading required package: RODBC DB<-
> RODM_open_dbms_connection(dsn="****",uid="****", pwd="****") Error in
> typesR2DBMS[[driver]] <<- value[c("double", "integer", "character", :
> cannot change value of locked binding for 'typesR2DBMS'
Have you tried ROracle? After you get the instant client installed on your machine, connecting and fetching records from R looks like this:
library(ROracle)
con <- dbConnect(dbDriver("Oracle"), username="username", password="password", dbname = "dbname")
res <- dbSendQuery(con, "select * from schema.table")
dt <- data.table(fetch(res, n=-1))
I explored the RODM_open_dbms_connection. I commented out the part setSqlTYpeInfo(). After that I didn't receive that error.
Install RODM package from source then only you can edit the package.
