// -------------------------------------------------------------------------
// This table contains defaults used in SQLARK.
// To add a default, put it in sqlcomp/DefaultConstants.h and in this table.
//
// The #define declares the domain (allowed range of values) of the attr-value;
// typically it is Int1 or UI1 (signed or unsigned integral, >=1)
// to prevent division-by-zero errors in the calling code.
//
// The first column is the internal enum value from sqlcomp/DefaultConstants.h.
// The second column is the default value as a string.
//
// The DDxxxx macro identifies the domain of the attribute
// (the range and properties of the possible values).
//
// XDDxxxx does the same *and* externalizes the attribute
// (makes it visible to SHOWCONTROL; *you* need to tell Pubs to document it).
//
// SDDxxxx does the same and externalizes the attribute to HP support personnel
// (makes it visible to HPDM when support is logged on; *you* need to tell Pubs
//  to document it in the support manual. You can set the
//  SHOWCONTROL_SUPPORT_ATTRS CQD to ON to see all the externalized and
//  support-level CQDs).
//
//  For instance, DDflt0 allows any nonnegative floating-point number, while
//  DDflte allows any positive float (the e stands for epsilon, that tiniest
//  scintilla >0 in classical calculus, and something like +1E-38 on a Pentium).
//  DDui allows only nonnegative integral values (ui=unsigned int),
//  DDui1 allows only ints > 0, DDui2 only nonzero multiples of 2, etc.
//
//  DDkwd validates keywords.  Each attribute that is DDkwd has its own subset
//  of acceptable tokens -- the default behavior is that the attr is bivalent
//  (ON/OFF or TRUE/FALSE or ENABLE/DISABLE).  If you want different keywords,
//  see enum DefaultToken in DefaultConstants.h, and NADefaults::token() below.
//
//  Other DD's validate percentages, and Ansi names.  Certainly more could be
//  defined, for more restrictive ranges or other criteria.

// *************************************************************************
// NOTE: You must keep the entire list in alphabetical order,
// or else the lookup will not work!!!!!!! Use only CAPITAL LETTERS!!!!!!!!!
// *************************************************************************
// NOTE 2: If you choose to "hide" the default default value by setting it to
// "ENABLE" or "SYSTEM" or "", your code must handle this possibility.
//
// See OptPhysRelExpr.cpp's handling of PARALLEL_NUM_ESPS,
// an unsigned positive int which also accepts the keyword setting of "SYSTEM".
// See ImplRule.cpp's use of INSERT_VSBB, a keyword attr which allows "SYSTEM".
//
// A simple way to handle ON/OFF keywords that you want to hide the default for:
// Take OPTIMIZER_PRUNING as an example.  Right now, it appears below with
// default "OFF", and opt.cpp does
//	DisablePruning = (NADEFAULT(OPTIMIZER_PRUNING) == DF_OFF);
// To hide the default default,
// you would enter it below as "SYSTEM", and opt.cpp would do
//	DisablePruning = (NADEFAULT(OPTIMIZER_PRUNING) != DF_ON);
// (i.e., DF_OFF and DF_SYSTEM would be treated identically, as desired).
// *************************************************************************
// NOTE 3: The user is always allowed to say
//	CONTROL QUERY DEFAULT attrname 'SYSTEM';   -- or 'ENABLE' or ''
// What this means is that the current setting for that attribute
// reverts to its default-default value.  This default-default value
// may or may not be "SYSTEM"; this is completely orthogonal/irrelevant
// to the CQD usage.
//
// One gotcha:  'ENABLE' is a synonym for 'SYSTEM', *EXCEPT* when the
// SYSTEM default (the default-default) is "DISABLE".
// In this case, 'ENABLE' is a synonym for 'ON'
// (the opposite of the synonyms DISABLE/OFF).
// *************************************************************************
// NOTE 4: After modifying this static table in any way, INCLUDING A CODE MERGE,
// for a quick sanity check, run w:/toolbin/checkNAD.
// For a complete consistency check, compile this file, link arkcmp, and
// runregr TEST050.
