--mappings 

-- objectClass mappings: these may be viewed as structuralObjectClass, the ones that are used to decide how to build an entry
--      id              a unique number identifying the objectClass
--      name            the name of the objectClass; it MUST match the name of an objectClass that is loaded in slapd's schema
--      keytbl          the name of the table that is referenced for the primary key of an entry
--      keycol          the name of the column in "keytbl" that contains the primary key of an entry; the pair "keytbl.keycol" uniquely identifies an entry of objectClass "id"
--      create_proc     a procedure to create the entry
--      create_keyval   a query that returns the id of the last inserted entry
--      delete_proc     a procedure to delete the entry; it takes "keytbl.keycol" of the row to be deleted
--      expect_return   a bitmap that marks whether create_proc (1) and delete_proc (2) return a value or not

-- attributeType mappings: describe how an attributeType for a certain objectClass maps to the SQL data.
--      id              a unique number identifying the attribute       
--      oc_map_id       the value of "ldap_oc_mappings.id" that identifies the objectClass this attributeType is defined for

--      sel_expr        the expression that is used to select this attribute (the "select <sel_expr> from ..." portion)

--      join_where      the expression that defines the condition to select this attribute (the "select ... where <join_where> ..." portion)

--      delete_proc     a procedure to delete the attribute; it takes the value of the attribute that is added, and the "keytbl.keycol" of the entry it is associated to
--      param_order     a mask that marks if the "keytbl.keycol" value comes before or after the value in add_proc (1) and delete_proc (2)
--      expect_return   a mask that marks whether add_proc (1) and delete_proc(2) are expected to return a value or not
