Hi, I'm developing a script which contains a multi dimensional array, however for some reason the array is not iterating.
When executing the script, services are listed as arguments from argument 2. Ex voice data sms.
service=${@:2};
for services in $service

I have an array of names. Each one of the name, has a number represented to it.
For example A has an ID 8, B has an ID 2.
What I am after is a for loop that when the array is in position 1, a particular variable is set to the value of position 1 in array 2
declare -a arr=("A" "B" "C"... (6 Replies)
I cant get out of this while loop at the beginning of my program. Just reading from stdin one char at a time and storing it into a multi-array. Need to fix it with in two hours.

Hi.
I am reasonably new to awk, but have done quite a lot of unix scripting in the past. I have resolved the issues below with unix scripting but it runs like a dog. Moved to awk for speed and functionality but running up a big learning curve in a hurry, so hope there is some help here.

So, I'm fooling around with multi demtional arrays, and I made this in a short amount of time:
#include <stdio.h>
main(int argc, char *argv) {
char blah = {
{'a', 'b'},
{'b', 'a'}
};
int i = 0;
while (i < 2) {
if (argv == blah)
printf("%c\n", blah);
i++;
}
}
The goal... (3 Replies)

Tangram::Relational - Orthogonal Object Persistence in Relational Databases
SYNOPSIS
use Tangram;
$schema = Tangram::Relational->schema( $hashref );
Tangram::Relational->deploy($schema, $dbh);
$storage = Tangram::Relational->connect( $schema,
$data_source, $username, $password );
$storage->disconnect();
Tangram::Relational->retreat($schema, $dbh);
DESCRIPTION
This is the entry point in the vanilla object-relational persistence backend. Vendor-specific backends should be used when they exist. Cur-
rently Mysql, Sybase and Oracle have such backends; see Tangram::mysql, Tangram::Sybase and Tangram::Oracle.
More backends could be added in the future; they might implement persistence in XML documents, pure object databases, using C database
libraries to bypass the need for an RDBMS, etc.
CLASS METHODS
schema
$schema = Tangram::Relational->schema( $hashref );
Returns a new Schema object. See Tangram::Schema.
deploy
Tangram::Relational->deploy($schema);
Tangram::Relational->deploy($schema, HANDLE);
Tangram::Relational->deploy($schema, @dbi_args);
Writes SQL statements for preparing a database for use with the given $schema.
Called with a single argument, writes SQL statements to STDOUT.
Called with two arguments, writes SQL statements to HANDLE. HANDLE may be a DBI connection handle or a file handle.
Called with more than two arguments, passes all but the first to DBI::connect() and writes statements to the resulting DBI handle, which is
automatically closed.
The SQL code is only guaranteed to work on newly created databases.
connect
$storage = Tangram::Relational->connect( $schema,
$data_source, $user, $password, \%options )
Connects to a storage and return a handle object. Dies in case of failure.
$schema is a Schema object describing the system of classes stored in the database.
$data_source, $user and $password are passed directly to DBI::connect().
\%options is a reference to a hash containing connection options. See Tangram::Storage for a description of available options.
retreat
Tangram::Relational->retreat($schema);
Tangram::Relational->retreat($schema, HANDLE);
Tangram::Relational->retreat($schema, @dbi_args);
Remove the tables created by deploy(). Only guaranteed to work against a database that was deployed using exactly the same schema.
For an explanation of the possible argument lists, see deploy.
WRITING A VENDOR DRIVER
Like Charles Moore (inventor of Forth) used to say, "standards are great, everybody should have one!".
Tangram can take advantage of extensions available in some SQL dialects.
To create a vendor-specific driver, call it "Tangram::Foo" (where "Foo" is the name of the DBI driver, as would be selected with the DBI
connection string "dbi:Foo:"), and derive "Tangram::Relational".
For now, the existing back-ends should be used as examples of how to extend Tangram to support different databases or utilise some of their
more exotic features.
