How to insert data befor some field in a row of data depending up on values in row
Hi
I need to do some thing like "find and insert before that " in a file which contains many records. This will be clear with the following example.
The original data record should be some thing like this
but due to some system errors the file generated has got one missing information and it looks like
both has got 248 charaters length. but in the second record one data is missing i.e 441
i need to insert 441 exactly in that position if 442 is available as next data.
its some thing like case statements...
i will be having different values instead of 442 and their corresponding previous position data
How to go about this...any one help me out...
Am having lot of error files like this to be treated, hence can i do anything like upload in a DB and insert data based on the values in the row at the position i told before (442)
I have a datafile having structure like
col1,col2,col3
col1,col2,col3,col4,col5
col1,col2,col3,col4,col5
.....
Can we take only first row of values from datafile and put into respective variable.
How col1 can be captured in a variable called v_col1 from unix script.
like first row(only)... (1 Reply)
Guys -- I am noob and I am really strugging on this one. I cant even write the pseudo code for it. I have a file that spits values in individual rows as such:

Hello,

Where '_' is a space. The data is in a table. Is there a way for the program to prompt the user for x1,y1 and x2,y2, where x1,y1 is the desired number (for example x=6 y=4 is a value of 4) and move to a desired spot... (2 Replies)

alzabo::runtime::uniquerowcache
Alzabo::Runtime::UniqueRowCache(3pm) User Contributed Perl Documentation Alzabo::Runtime::UniqueRowCache(3pm)NAME
Alzabo::Runtime::UniqueRowCache - Implements a row cache for Alzabo
SYNOPSIS
use Alzabo::Runtime::UniqueRowCache;
Alzabo::Runtime::UniqueRowCache->clear();
DESCRIPTION
This is a very simple caching mechanism for "Alzabo::Runtime::Row" objects that tries to ensure that for there is never more than one row
object in memory for a given database row.
To use it, simply load it.
It can be foiled through the use of "Storable" or other "deep magic" cloning code, like in the "Clone" module.
The cache is a simple hash kept in memory. If you use this module, you are responsible for clearing the cache as needed. The only time it
is cleared automatically is when a table update or delete is performed, in which case all cached rows for that table are cleared.
In a persistent environment like mod_perl, you should clear the cache on a regular basis in order to prevent the cache from getting out of
sync with the database. A good way to do this is to clear it at the start of every request.
METHODS
All methods provided are class methods.
* clear
This clears the entire cache
* clear_table( $table_object )
Given a table object, this method clears all the cached rows from that table.
* row_in_cache( $table_name, $row_id )
Given a table name and a row id, as returned by the "Alzabo::Runtime::Row->id_as_string" method, this method returns the matching row
from the cache, if it exists. Otherwise it returns undef.
* delete_from_cache( $table_name, $row_id )
Given a table name and a row id, as returned by the "Alzabo::Runtime::Row->id_as_string" method, this method returns the matching row
from the cache.
* write_to_cache( $row_object )
Given a row object, this method stores it in the cache.
AVOIDING THE CACHE
If you want to not cache a row, then you can pass the "no_cache" parameter to any table or schema method that creates a new row object or a
cursor, such as "Alzabo::Runtime::Table->insert()", "Alzabo::Runtime::Table->rows_where()".
