Member Function Documentation

constructor()

FreetdsSqlUtil::FreetdsPrimaryKey::constructor	(	string	n,
		*hash	c,
		*string	ts
	)

creates the object with the given attributes

Parameters

n	name of the constraint
c	column hash
ts	optional filegroup name

memberGate()

FreetdsColumn FreetdsSqlUtil::FreetdsPrimaryKey::memberGate

(

string

k

)

returns the FreetdsColumn value of the given key if it exists, otherwise throws a KEY-ERROR exception

Example:

any v = c.name;

Parameters

k	the name of the key to access

Returns

the value of the given key in the contained hash if it exists

Exceptions

KEY-ERROR

the given key does not exist in the contained hash

Note

this method is called automatically when an unknown or inaccessible member name is accessed from outside the class
