Name
Conf::SQL - The file backend for Conf.
Abstract
Conf::SQL is an SQL backend for Conf. It handles a table $table with identifiers that are assigned values. The identifiers are specified on a per user basis. Conf::SQL tries to get the user account of the user self.
Note
This module can be ommitted from the Conf bundle. One can optionally neclegt it's existence by using perl Makefile.PL --no-sql.
Description
Each call set() will immediately result in a commit to the database.
new(DSN = ...,DBUSER => ..., DBPASS =>, [TABLE => ...])> --> Conf::SQL
Invoked with a valid DSN, DBUSER and DBPASS combination, will return a Conf::SQL object that is connected to the database.
TABLE defaults to conf_table.
This function will try to create a TABLE table in the given DSN, if it does not exist.
Creating the table $table in your database
If it cannot create a table for you, because it doesn't know the database you are using, you can create your own. The table used has following form:
CREATE TABLE $table(uid varchar,var varchar,value varchar)The form presented here is a PostgreSQL form. You will want at least following specifications for uid, var and value:
uid varchar(250)
var varchar(250)
value text, bigtext, mediumtext, varchar(1000000000), etc.You may also want an index on $table, like this one:
"CREATE INDEX $table"."_idx ON $table(uid, var)"DESTROY()
This function will disconnect from the database.
set(var,value) --> void
Sets config key var to value.
get(var) --> string
Reads var from config. Returns undef, if var does not exist. Returns the value of configuration item var, otherwise.
variables() --> list of strings
Returns all variables in the configuraton backend.
