String data = “hello world”;
java.sql.Blob blob = org.hibernate.Hibernate.createBlob(data.getBytes());

Convert Blob to String

byte[] bdata = blob.getBytes(1, (int)blob.length());
String data1 = new String(bdata);

if the length of blob exceeds the maxvalue for the int, then u can use CLOB format.To store large data we can use CLOB format and to store an image, use a BLOB data types.

inside the Javascript tag,

startsWith to check if a string starts with a particular character sequecnce:

var data = “Helloo Good Morning”;
startsWith
String.prototype.startsWith = function(data)
{
return (this.match(“^”+data)==data)
}

eg:
data.startsWith(“Helloo”);
returns true

endsWith Function

endsWith to check if a string ends with a particular character sequecnce:

String.prototype.endsWith = function(data)
{
return (this.match(data+”$”)==data)
}

eg:
data.endsWith(“Helloo”);
returns false;

Javascript trim function

function

trim(stringToTrim) {

return
stringToTrim.replace(/^\s+|\s+$/g,”");

}

In this sample code, an exception occured i.e “Stream has already been closed; nested exception is java.sql.SQLException”, In case java – Oracle connectivity this kind of exception thrown out. Reason for this exception, the table contains a datatype (long) field.

sample code

selProcess = conn.prepareStatement  (“select data(this is Long raw column),
intername, transid, transorder, errorcount, emailsent from max_interdata
order by transid, transorder, rowstamp”);

ResultSet rsetMax = selProcess.executeQuery();

try
{
while (rsetMax.next())
{

//08/15/02, JB — using getBinaryStream() instead
of getBytes() to
//work around Oracle driver bug
InputStream inputStream = null;
try
{
inputStream = rsetMax.getBinaryStream(1);
data = readBinaryData(inputStream);
// method to convert the inputsream to my object
interfaceName = rsetMax.getString(2);
transID = rsetMax.getLong(3);
transOrder = rsetMax.getLong(4);
errorCount = rsetMax.getInt(5);
emailSent =  rsetMax.getString(6);
}

For example:

‘Customer is the table name contains a field ‘order’ long datatype

To solve this exception, replace the datatype ‘long‘ field to ‘number‘ datatype
