Java.sql.Types.??????

I know clob columns in an oracle database are java.sql.Types.CLOB. What are long raw columns defined as java.sql.Types.???
Thanks in advance,
kmw

Hi ,
Long has no correspondng type in Oracle.sql.Types.So u can access it using the getOBject and setObject.Why do u need to defing the long ?Is it for use i the getter and setter methods of ResultSet or Statements.If so , u have to use streaming and so there is really no need to worry abt the type definition as u are defaulting to an AsciiStream.
Hope it helps.

Java.sql.types and oracletypes

There appear to be difference in the way the constants are mapped in java.sql.types vs oracletypes(). For example date is '91' in oracletypes and '93' in java.sql.types. The DatabaseMetaData.getColumns() function reports data_type as a java.sql.type. Is there any mapping available from one to the other.
Thanks

Erm,
One way to find out, I reckon.
Good Luck,

Create table dinamically using java sql types?

Hi! I've an application that reads an XML file. This file contains de definitions of some tables, using java sql types. For example:
<dbtable>
<dbtablename>Name of table</dbtablename>
<dbtablefield>
 <name>Name of table field</name>
 <type>java.sql.Types.VARCHAR</type>
 <length>10</lenght>
 <canNull>0</canNull>
 <isPK>1</isPK>
</dbtablefield>
</dbtable>That's a little example of one table, with one field. Is a java.sql.Types.VARCHAR (or is equivalent in int), which has a size of 10, it cannot be null and is a primary key for the table.
Now, the lenght, null, and primary keys are not problem at all. What I want to know, is how do I create de table using the java.sql.Types. I mean, I don't want to hard code:
String s = "CREATE TABLE name (COLUMN VARCHAR(10)...";Instead, I want to use some "wild cards", as are used in PreparedStatement. The idea of this is that no matter what DB I'm using, I must always be capable of creating the tables not worrying for the DB. I mean, I must be able to create the table in Oracle, SQL Server, DB2, etc., using the same XML and the same java class.
Something like:
String s = "CREATE TABLE name (COLUMN ? (10)...";
someobject.setObject(1,java.sql.Types.VARCHAR);
someobject.execute(); //create tableIs this possible? Or do I have to make a map for each DB?
Thanks a lot for your help! Dukes available!

you can provide some fields at runtime..
for example
"CREATE TABLE name (COLUMN" + arg[1] +"(10)..."
here arg is the string array passed into the main.

Name of an int ( e.g. java.sql.Types )

I have the sql.Types code as an int number and want to display the name. Is there a straightforward method or do I have to search it in a loop like here ?
String getName(int i) {
for (Field f: java.sql.Types.class.getFields()) {
     if (f.getType().equals(int.class)) {
          if (f.getInt(f.getType()) == i) {
          System.out.println( i + " = "+f.getName() );
          // e.g.               8 = DOUBLE
          return f.getName();
}This question is not specific to java.sql.Types I guess (that's why I post here).
A dedicated hint for sql is appreciated as well, however ;)

Seems the loop is required and it works (in no time, there aren't too many Fields)
     if (f.getInt(f.getType()) == i) {Having a closer look, I do not understand the inner f.getType() , however.
f.getInt() requires an object, but anything, including null, works ?!
Any hint, or link where to learn about java.lang.reflect.Field, please ?

SetNull(2, java.sql.Types.DATE);

If I use setNull(1, java.sql.Types.DATE); function, it will insert null on my table's column.
I want to select the date from another table and insert into my table's column, what should I do?
I am sure I cannot call setNull(1,java.sql.Types.DATE), it will insert NULL in my column.
Thanks in advance.

Hi,
I think you will be better of in asking ths question in Java forum or Oracle Developer forum.

Java.sql.Types.RAW

I know you can map a LONG RAW sql type to the java class oracle.sql.RAW when wrapping the java code in your pl/sql wrapper. The problem I am having is that within my java code I am returning result set and using reslutSetMetaData to determine if the column is a varchar or clob with a switch statment and a case comparison using java.sql.Types.whatever sql type i am looking for. I am running into a problem when trying to write a case statement for long raw columns. What would be the statement to use for this. Below is an example of the code.
int type = rsmd.getColumnType(1);
switch (type) {
case java.sql.Types.CLOB:
code to execute when CLOB type
break;
case java.sql.Types.Raw:
code to execute when LONG RAW type
break;
Thanks in advance,

...the return type which is defined inside DBMS_XDB_VERSION package
I think there are some threads somewhere that points to Oracle documentation somewhere that says that is not possible with JDBC.
I could certainly be mistaken however.
If I am not mistaken then you would need to
1. Wrap the call to that in another proc.
2. That proc extracts the result into something that is visible in the jdbc driver.

Java.sql.Types.CLOB not returned

When I run the following on an oracle 8.1.7 server using thin/OCI driver on a table with a CLOB column,
DatabaseMetaData dbmd = conn.getMetaData();
ResultSet rs = dbmd.getColumns( null, null, tableName, "%" );
while (rs.next()){
int colType = (int)rs.getShort(5);
I dont get java.sql.Types.CLOB returned in colType, instead I get java.sql.Types.OTHER.
However, after a query on the same table, the result set metadata.getColumnType() returns java.sql.Types.CLOB.
Any ideas?
Thanks in advance

You can't do that. You can't do it in SQL either: there's no way to call a stored procedure without providing parameters of a specific type.
There are two things you can do, however: one is to declare the parameter as VARCHAR and hope it's not a BLOB or something that the db will not automatically convert to VARCHAR and the other is to do a SELECT in the procedure you are calling instead of returning the value as an output parameter. The second option is better in that you can then use ResultSet.getObject() from Java and obtain the correct object type, not a String you might need to parse afterwards.

Java.sql.Types.BOOLEAN in 9i

I am trying to figure out what data type i need to set on columns in 9i that will represent java.sql.Types.BOOLEAN data. The docs that i have read around the web say to use a "Byte" type but this is not in the list on my server; in MS SQL2000 i use the "Bit" type and it works great.. is there something simlar in Oracle?

If DB Column java.sql.Types=CHAR = Workshop autogen EJB CMP Filed=Boolean

Hi everybody 
When a user automatically
creates/generates an Entity Bean via BEA Workshop EJB Project option: â€˜new
Entity bean from database tableâ€™ and DB Table Column is of type CHAR,
Workshop creates a @ejbgen:cmp-field of Java type Boolean, NOT of
Character!
I completely agree that the developer
must be acquainted with the Data Base and DB Tables as well and he can manually
correct SET & GET
Boolean to Character in EJB source code view or heâ€™ll receive an error if he
tries to setFieldName(String/Character) in ejb
methods.
But suppose that a developer has
urgently received an order to build an EJB Project for a thousand of DB Tables
and he hasnâ€™t been acquainted with all of them. He has created the EJBs via 
â€˜new -> Entity bean from database tableâ€™. He has created some EJB Finders,
for example a finder:Â ejbgen:finder Collection findAll().
(Suppose he hasnâ€™t used group-name finder property)
He has invoked findAll()
method and depends on the JDBC Driver used, he will receive an 
ERROR,
printed within the Server start console at least OR the result after 
getFieldName() will be 'false', not an expected char
symbol.
Anxious conclusion: 
If Â DB Column Â java.sql.Types
= CHAR Â Â Â thenÂ Â
getJavaObjectType = BooleanÂ then corresponding
EJB CMP FiledÂ will always be Â Â BooleanÂ in BEA Workshop !
Following description considers the
PROBLEM:
Class
weblogic.jdbc.utils.schema.Column from weblogic.jar and its method
String getJavaType() has a switch(getType()) with case:
Â if(this.getSize() == 1) 
Â Â Â return "boolean"; 
else 
Â Â Â return "String";
and 

another Â method String getJavaObjectType() 
{
String s = this.getJavaType();
...
Â Â Â Â
if(s.equals("boolean")) 
Â Â Â Â Â Â Â return "Boolean";
Â Â Â Â
if(s.equals("char")) 
Â Â Â Â Â Â Â return "Character";
... } 
but according to switch(getType()) which
has NOTÂ a 'case' return char, 
'Character' will never be returned, so:
@ejbgen:cmp-field of Java type 
Character will never be generated by Workshop.
More often than not Â Iâ€™ve
ran into this little but disturbing problem, so Iâ€™ve corrected 
weblogic.jdbc.utils.schema.Column.getJavaType switch case as:
â€¦
Â Â Â Â Â Â Â
case 1: Â Â Â Â // '\001'Â //CHAR

Â Â Â Â Â Â Â Â Â Â Â if(this.getSize() == 1)
Â Â Â Â Â Â Â Â Â Â
Â Â Â Â Â return "char";Â 
â€¦
private
static final boolean 
CHAR_TO_BOOLEAN = false;Â Â Â Â //as
a field variable
â€¦
Â 
Using this
correction and precompiled class Iâ€™ve built and tested a lot of projects w/o
problems so far.
Best regards: George Moykin
P.S. I appologize to site Admins for posting the same topic in EJB forum, but it refers to EJBs too.

Hi, 
In your database, we have some columns of CHAR type and this is the decision of our DB architects. I understand the case â€˜maleâ€™ or â€˜femaleâ€™, true or false, either; but only if I must choose between 2 variants. Our DB columns contain char symbols such as â€˜:â€™, â€˜;â€™,â€™-â€™ etc. and for some inner purposes our architects decided DB columns to be of type CHAR, not VARCHAR. In this case, the Workshop transformation â€˜CHAR to BOOLEANâ€™ doesnâ€™t do useful work. So, Iâ€™ve decided to modify some weblogic.jar classes (as described) and now Iâ€™m able to generate Entity EJB from DBMS Tables w/o manual intervention. 
Best Regards

Help on java.sql.Types class

Hai Friends ,
I want some help on java.sql.Types class .
What is the use of the above class ?
Some details about this class.

Good Morning Yekesa
First of all i would like to thank U for looking into my problem.
I am using java.sql.Types.OTHER for
{"?=CALL(storedprocedurename.functionname(?))"}
registerOutParameter(1,javal.sql.Types.OTHER)
setString(2,"user")
here the
second parameter passes an argument to function name ( viz. username say "user")
and the function will return the ref cursor as follows:
// declaration in pl/sql procedure
begin
rc ref cursor
open rc for select * from ss_user where login_name="user";
return rc;
end
now the stored procedure has a return value (i.e. stored function) which it needs to register as
registerOutParameter(1,javal.sql.Types.OTHER)
and it finally results in the following errors :
Loading driver
Before conn stmt
After conn stmt
Calling Stored procedure
Stored procedure called
java.sql.SQLException: Invalid column type

at sptest.<init>(sptest.java:28)
at sptest.main(sptest.java:49)
T couldn't understand why it is saying Invalid Column Type because its working fine with both
java.sql.Types.INTEGER
and
java.sql.Types.VARCHAR
Pl help me at the earliest as i have wasted a lot of time on it.

Sql type to Java class?

I want to write a utility class to generate a java source file (bean) from out of the metadata of a database table. the metadata returns the column type as a java.sql.Types constant (int value). now, i want to map these int values to Java classes. (e.g. Types.INT => java.lang.Integer). Is there already such a method in the API or do i have to write my own switch ... case Types.INT ... result = Integer.class ... method?

well, i wrote my own utility method to generate such beans:
     * Convert SQL type code to corresponding Java class.
     * @param sqlType One of java.sql.Types.xxx.
     * @return Class that corresponds to the given type.
    public static Class toClass(int sqlType) {

Java.sql.SQLException: Internal Error: Inconsistent catalog view

Hi all,
I have an Oracle procedure defined like:
pkgoms.p_oms_audit ( in_tab_oms_audit in tab_oms_audit,out_status out number)
tab_oms_audit is a collection of t_oms_audit
Here is the structure for the type (with 16 fileds)
create or replace type t_oms_audit as object(
Username_ VARCHAR2(101),
d_Date_ Date,
<other fields>) ;
In my Java code I have:
// conn is the connections to db
oracle.sql.StructDescriptor structDesc = oracle.sql.StructDescriptor.createDescriptor("TAB_OMS_AUDIT", conn);
Object[] attributes = new Object[16];
// Fill out the array: attributes[] in the same structure that t_oms_audit is defined
// Receive the following error on the next line:
// java.sql.SQLException: Internal Error: Inconsistent catalog view
oracle.sql.STRUCT struct = new oracle.sql.STRUCT(structDesc, conn, attributes);
anOracleCallableStatement.setObject(1, struct, java.sql.Types.STRUCT);
anOracleCallableStatement.execute();I searched for the above error and the only thing I could find was that its a permission issue; I can execute select, update, insert, delete, ... on db, so not sure if its in fact a permission issue or I am doing sth. else wrong. Any help is greatly appreciated.

Hi all
I have the same problem.
it's not a GRANT problem because in PL/SQL the object works fine.
JDBC Release problem?
Any help is greatly appreciated.

Please help. I am using weblogic 8.1 and MS SQL Server 2000. Using JDBC. I have am calling a stored procedure which outputs a CURSOR. I haveing problems specifying the right java.sql.Type for this. I tried java.sql.Type.OTHER but it fails. The code is as follows
I am planning to return more cursors from the Stored Procedures.
====
Connection conn = null;
CallableStatement stmt = null;
String sqlProc = "{ call GetDocumentDetails(?,?) }";
try {
conn = this.getConnection();
stmt = conn.prepareCall(sqlProc);
stmt.setInt(1, docId);
stmt.registerOutParameter(2,Types.OTHER);
stmt.execute();
ResultSet rs = (ResultSet) stmt.getObject(2);
while(rs.next()) {
The exception that I get is
java.sql.SQLException: [BEA][SQLServer JDBC Driver]The specified SQL type is not supported by this driver.
     at weblogic.jdbc.base.BaseExceptions.createException(Unknown Source)
PLEASE HELP.

my javabeans code snippets is as follows.
Connection con;
CallableStatement cstmt;
private static String theaddcall = "{ ? = call sp_ins_client1_defect ( ?,?,?,?,?,?,?,?,?,?,?,?,?,?,? )}";
con = DbUtil.getConnection("dts");
cstmt = con.prepareCall(theaddcall);
session.setAttribute("attack","akraman2");
cstmt.registerOutParameter( 1, java.sql.Types.VARCHAR ); //ret code
cstmt.setInt ( 2, getDefectstatus());
session.setAttribute("attack","2");
cstmt.setInt ( 3, priority );
cstmt.setInt ( 4, complexity);
cstmt.setInt ( 5, defecttype);
cstmt.setString( 6 ,desc);
cstmt.setString( 7, sourcefile);
session.setAttribute("attack","3");
cstmt.setString( 8, sourcefileloc );
cstmt.setString( 9, testcasefile );
session.setAttribute("attack","4");
cstmt.setString( 10, testcaseno );
cstmt.setString( 11, steps2rep );
cstmt.setString( 12, comments );
session.setAttribute("attack","5");
cstmt.setString( 13, prodver );
cstmt.setInt ( 14, projids );
cstmt.registerOutParameter(15, java.sql.Types.VARCHAR );
session.setAttribute("addd","1");
boolean result=cstmt.execute();
session.setAttribute("addd","2");
while (result=cstmt.getMoreResults()) {};
/* rest of the code is here */
if possible please solve there query.
From ShivNarayan

"{ ? = call sp_ins_client1_defect ( ?,?,?,?,?,?,?,?,?,?,?,?,?,?,? )}";When I count the about I get 16 '?' (one return and 15 args)
The stored proc only has 14 args and you only populate 14.

Java.sql.SQLException: Invalid column index error While getClob()

I have code which works fine in Iplanet or stand alone Java program using WLS Connection Pool, But not from the the WLS servlet.
This uses 9.1 Oracle JDBC Thin Driver
Code snippet:
cstmt.setString(1, servicename);
cstmt.setString(2, params);
String resultXmlString = null;
cstmt.registerOutParameter(3,java.sql.Types.CLOB);
cstmt.execute();
Clob clob = cstmt.getClob(3);
int val;
long size = clob.length();
StringBuffer full_text = new StringBuffer();
if (clob != null)
java.io.Reader clobReader = clob.getCharacterStream();
while((val = clobReader.read()) > 0)
full_text.append((char) val);
resultXmlString = full_text.toString();
