SYNOPSIS

package foo;
use Meta::Db::Ops qw();
my($scod)=Meta::Db::Ops::act($connection,$dbdef);

DESCRIPTION

This module does various database related tasks like exporting from databases in a generic fashion, translating database names so that development environments could use the same DB server as production environments and not have to worry about messing with the same actual databases, cleaning out databases and other tasks that fall in no other modules ballpark.

FUNCTION DOCUMENTATION

act($$)

This will actually do the work of creating. You need to supply a connection object and a definition object.

export_writ($$$$)

This method will export the content of a database to an XML::Writer object. This method does not prepare statements since when you prepare a statement you have to know the exact number of parameters that you want and we dont: for each table the statement should be "SELECT (f1,f2,f3,...,fn) FROM table;" and the number of fields is changing. We do NOT wish to use a stupid: "SELECT * FROM table;" since we know which fields are there and we could avoid errros by doing this.

export_hand($$$$)

This method does the same as export_writ except it writes everything to a file handle and takes care of the writer itself.

export_file($$$$)

This method does the same as export_hand except it actually creates a new file.

import($)

This method will import the content of an XML file into a database. It uses a parser to achieve this (the idea is not store the entire XML in RAM and then import it but rather do it record by record).

san($$$$$$$$)

This will actually do the sanity tests.

sindex($$$)

This will check that all indices are ok in the database.

clean_sa($)

This is a clean stand alone method. Give it a database handle already connected to a database and it will clean it out by finding out which tables it has and issuing a DELETE statement for each.

dbname_name_to_deve($)

This method translates a db name from cannonical to development.

dbname_deve_to_name($)

This method translates a db name from development to cannonical.

dbname_name_to_prod($)

This method translates a db name from cannonical to production.

dbname_prod_to_name($)

This method translates a db name from production to cannonical.

dbname_deve_to_prod($)

This method translates a db name from development to production.

dbname_prod_to_deve($)

This method translates a db name from production to development.

TEST($)

Test suite for this object.

SUPER CLASSES

None.

BUGS

None.
