Request: How to Parse dynamic SQL query to pad extra columns to match the fixed number of columns
Hello All,
I have a requirement in which i will be given a sql query as input in a file with dynamic number of columns. For example some times i will get 5 columns, some times 8 columns etc up to 20 columns.
So my requirement is to generate a output query which will have 20 columns all the times irrespective of number of input columns.
Sample input file
Expected output
Can someone one please help me achieve this in UNIX KSH/BASH?
Hi,
I need a script that will run a dynamic Oracle SQL. Dynamic meaning the SQL statement depends on the parameter.
For instance, something like this:
#!/bin/ksh -x
# Set environment
. /home/mine/set_vars
sqlplus $LOGINID <<! >> /home/mine/log.txt
select count(1) from $1

I have data extracted like this:
A=%123% B=%456% C=%789%
A=%111% B=%222% C=%333%
A=%777% B=%888% C=%999%
Can someone please help me with a script to remove all the % signs and get the totals for A, B and C.
So output will be:
A=1368
B=666
C=2664
Thank you! (2 Replies)

class::dbi::query
Class::DBI::Query(3pm) User Contributed Perl Documentation Class::DBI::Query(3pm)NAME
Class::DBI::Query - Deprecated SQL manager for Class::DBI
SYNOPSIS
my $sth = Class::DBI::Query
->new({
owner => $class,
sqlname => $type,
essential => @columns,
where_columns => @where_cols,
})
->run($val);
DESCRIPTION
This abstracts away many of the details of the Class::DBI underlying SQL mechanism. For the most part you probably don't want to be
interfacing directly with this.
The underlying mechanisms are not yet stable, and are subject to change at any time.
OPTIONS
A Query can have many options set before executing. Most can either be passed as an option to new(), or set later if you are building the
query up dynamically:
owner
The Class::DBI subclass that 'owns' this query. In the vast majority of cases a query will return objects - the owner is the class of which
instances will be returned.
sqlname
This should be the name of a query set up using set_sql.
where_clause
This is the raw SQL that will substituted into the 'WHERE %s' in your query. If you have multiple %s's in your query then you should supply
a listref of where_clauses. This SQL can include placeholders, which will be used when you call run().
essential
When retrieving rows from the database that match the WHERE clause of the query, these are the columns that we fetch back and pre-load the
resulting objects with. By default this is the Essential column group of the owner class.
METHODS
where()
$query->where($match, @columns);
This will extend your 'WHERE' clause by adding a 'AND $column = ?' (or whatever $match is, isntead of "=") for each column passed. If you
have multiple WHERE clauses this will extend the last one.
