NAME
Conf::SQL - An SQL 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.
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.
