DATABASE-NAME-FROM-SPEC — Return the database name string corresponding to the given connection specification.
Generic Function
database-name-from-spec connection-spec database-type => name
A connection specification, whose structure and interpretation are dependent on the database-type.
A database type specifier, i.e. a keyword.
A string denoting a database name.
This generic function takes a connection specification and a database type and returns the database name of the database object that would be created had connect been called with the given connection specification and database types.
This function is useful in determining a database name from the connection specification, since the way the connection specification is converted into a database name is dependent on the database type.
(database-name-from-spec '("dent" "newesim" "dent" "dent") :mysql) => "dent/newesim/dent" (connect '("dent" "newesim" "dent" "dent") :database-type :mysql) => #<CLSQL-MYSQL:MYSQL-DATABASE {48391DCD}> (database-name *default-database*) => "dent/newesim/dent" (database-name-from-spec '(nil "template1" "dent" nil) :postgresql) => "/template1/dent" (connect '(nil "template1" "dent" nil) :database-type :postgresql) => #<CLSQL-POSTGRESQL:POSTGRESQL-DATABASE {48392D2D}> (database-name *default-database*) => "/template1/dent" (database-name-from-spec '("www.pmsf.de" "template1" "dent" nil) :postgresql) => "www.pmsf.de/template1/dent" (find-database "dent/newesim/dent") => #<CLSQL-MYSQL:MYSQL-DATABASE {484E91C5}> (find-database "/template1/dent") => #<CLSQL-POSTGRESQL:POSTGRESQL-DATABASE {48392D2D}> (find-database "www.pmsf.de/template1/dent" nil) => NIL (find-database **) => #<CLSQL-POSTGRESQL:POSTGRESQL-DATABASE {48392D2D}>

None.
If the value of connection-spec is not a valid connection specification for the given database type, an error of type clsql-invalid-spec-error might be signalled.
