Using RAW in Jave Bean to store data in Oracle 8i database

Question

I have a question about using RAW in java program to read write data in Oracle database. Is there any sample with key information for me to refer to? Your help will be appreciated.

Jane Jane,
here is a code snippet provided by our QA team
hope it helps

1. Create the table:
"CREATE TABLE rawtable (key VARCHAR2(30), rawcol RAW(2000), longrawcol
LONG RAW, moredata VARCHAR2(100))"
2. Write the data:
byte x[] = {1,2,3,4,5};
byte y[]= {6,7,8,9,10};
PreparedStatement pstmtR =
conn.prepareStatement("INSERT INTO rawtable (key, rawcol,
longrawcol, moredata) VALUES (?, ?)");
pstmtR.setString(1, "rawcol data");
pstmtR.setBytes(2, x);
pstmtR.setNull(3, Types.LONGVARBINARY);
pstmtR.setString(4, "Here's some more data!");
pstmtR.execute();
pstmtR.setString(1, "longrawcol data");
pstmtR.setNull(2, Types.BINARY);
pstmtR.setBytes(3, y);
pstmtR.setString(4, "Here's some more data!");
pstmtR.execute();
pstmtR.setRAW(1, RAW_obj) can be used to insert the RAW data.
You can also use setBinaryStream to insert RAW data:
CallableStatement cstmt =
conn.prepareCall ("begin insert into rawtab values (?,?); end;");
cstmt.setBinaryStream (1, (java.io.InputStream) new
ByteArrayInputStream(rawbuf), rawbuf.length);
cstmt.setBinaryStream (2, (java.io.InputStream) new
ByteArrayInputStream(lrawbuf), lrawbuf.length);
3. Read the data:
InputStream is = null;
byte rawbuf [];
byte lrawbuf [];
ResultSet rset = stmt.executeQuery("SELECT rawcol, longrawcol FROM
rawtable");
// You can retrieve the data with the following methods
rawbuf = rset.getBytes(1);
lrawbuf = rset.getBytes(2);
RAW raw1 = rset.getRAW(1);
is = rset.getBinaryStream(column);
is = rset.getAsciiStream(column);
is = rset.getUnicodeStream(column);
When using CallableStatement:
((OracleCallableStatement)cstmt).registerOutParameter(1,
OracleTypes.RAW);
