    <p>I have written this code using the DBI module , Here is the code</p> <pre><code>#!/usr/local/bin/perl -w use DBI; use strict; # Open a connection my $dbh = DBI-&gt;connect("dbi:DB2:awdrt", "db2inst1", "db2inst1", {RaiseError =&gt; 1}); # use VALUES to retrieve value from special register my $stmt = "select RTRIM(substr(A.TBSP_NAME,1,30)),A.TBSP_TYPE as TYPE,A.TBSP_FREE_PAGES as FREE,B.CONTAINER_NAME as CON_PATH from SYSIBMADM.TBSP_UTILIZATION A ,SYSIBMADM.CONTAINER_UTILIZATION B where A.TBSP_ID=B.TBSP_ID and A.TBSP_AUTO_RESIZE_ENABLED=0 with UR"; my $sth = $dbh-&gt;prepare($stmt); $sth-&gt;execute(); # associate variables with output columns... my ($col1,$col,$col3,$col4); $sth-&gt;bind_col(1,\$col1); $sth-&gt;bind_col(3,\$col3); $sth-&gt;bind_col(4,\$col4); while ($sth-&gt;fetch) { if ($col3 &lt;= 2000){ print "$col1 has $col3 pages with container $col4\n";} } $sth-&gt;finish(); $dbh-&gt;disconnect(); </code></pre> <p>Here's the O/p : </p> <pre><code>TRANS_DATA has 1616 pages with container /adrst/bdts/trans_data_container MASTER_INDEX has 1872 pages with container /adrst/bdts/master_index_container TRANSACTION_INDEX has 1856 pages with container /adrst/bdts/transaction_index_container </code></pre> <p>And the table data when the query is executed is :</p> <pre><code>1 TYPE FREE CON_PATH ------------------------------ ---------- -------------------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- USERSPACE1 DMS 15056 /adrst/bdts/userspc_container USERSPACE1 DMS 15056 /adrst/bdts/userspc_container1 MASTER DMS 3584 /adrst/bdts/master_container TRANS_DATA DMS 1616 /adrst/bdts/trans_data_container MASTER_INDEX DMS 1872 /adrst/bdts/master_index_container TRANSACTION_INDEX DMS 1856 /adrst/bdts/transaction_index_container TEMP_SYS DMS 2192 /adrst/bdts/temp_sys_container AUDIT_DATA DMS 3360 /adrst/bdts/audit_data_container TEMP_USR DMS 2672 /adrst/bdts/temp_usr_container TSASNCA DMS 2840 /home/db2inst1/db2inst1/NODE0000/SQL00002/TSASNCA TSASNUOW DMS 2880 /home/db2inst1/db2inst1/NODE0000/SQL00002/TSASNUOW TSASNAA DMS 3712 /home/db2inst1/db2inst1/NODE0000/SQL00002/TSASNAA TSCDADDRESSMASTER DMS 2048 /home/db2inst1/db2inst1/NODE0000/SQL00002/CDADDRESSMASTER 13 record(s) selected. </code></pre> <p>What i am trying here basically report tablespaces with less than 2000 pages , Now my question is how do i do it without this module , What would be the better options , Hash,regex,grep? if so i need three columns to be reported as o/p , How do i do that using these or any thing that may come use? </p> <p>Help is appreciated.....</p>

    1. COWhy don't you use the DBI and related modules? If you don't, you have to write a lot of code to avoid it

    2. COThre really isn't a proper alternative to the `DBI` module for accessing databases. There are a few modules that subclass it to provide additional facilities, but nothing that avoiuds it altogether. Why do you want to write your program without it?

    3. COI have seen in a blog post that not every client will allow to intall the CPAN modules ......if that the case im looking for alternative . Hmm... but the same table data i can take in shell and could manipulate it to my use , so i was wondering if that table data could be sent to array or hash and get my required O/P

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
