Thanks. I got the information from INFORMATION_SCHEMA COLUMNS.
While retrieving the data from the result of query I faced following problem.
mysql> select select COLUMN_NAME, DATA_TYPE, IS_NULLABLE, CHARACTER_MAXIMUM_LENGTH, NUMERIC_PRECISION from INFORMATION_SCHEMA.COLUMNS where table_name='account');
In coding I run the query using mysql_real_query() whose result is stored in
pResult = mysql_store_result(pMySQLDB);
fields = mysql_fetch_field(pResult);
my_ulonglong noOfRows = mysql_num_rows(pResult);
row = mysql_fetch_row(pResult);
it will not return any rows.
But in fields I get select COLUMN_NAME, DATA_TYPE, CHARACTER_MAXIMUM_LENGTH, NUMERIC_PRECISION that I don't want.
I want the value of these field like "amit, "MY_VAR_STRING", '10', '0'.
I want to store these data inot another variable however not getting it.
Can you please tell me how do I fetch the data what I want from the query output or I am doing anything wrong?

apache::session::store::mysql
Session::Store::MySQL(3) User Contributed Perl Documentation Session::Store::MySQL(3)
NAME
Apache::Session::Store::MySQL - Store persistent data in a MySQL database
SYNOPSIS
use Apache::Session::Store::MySQL;
my $store = new Apache::Session::Store::MySQL;
$store->insert($ref);
$store->update($ref);
$store->materialize($ref);
$store->remove($ref);
DESCRIPTION
Apache::Session::Store::MySQL fulfills the storage interface of Apache::Session. Session data is stored in a MySQL database.
SCHEMA
To use this module, you will need at least these columns in a table called 'sessions', or another table name if you provide the TableName
argument:
id char(32) # or however long your session IDs are.
a_session text
To create this schema, you can execute this command using the mysql program:
CREATE TABLE sessions (
id char(32) not null primary key,
a_session text
);
If you use some other command, ensure that there is a unique index on the table's id column.
CONFIGURATION
The module must know what datasource, username, and password to use when connecting to the database. These values can be set using the
options hash (see Apache::Session documentation). The options are:
DataSource
UserName
Password
TableName
Handle
Example:
tie %hash, 'Apache::Session::MySQL', $id, {
DataSource => 'dbi:mysql:database',
UserName => 'database_user',
Password => 'K00l',
TableName => 'sessions'
};
Instead, you may pass in an already-opened DBI handle to your database.
tie %hash, 'Apache::Session::MySQL', $id, {
Handle => $dbh
};
