'boolean' datatype does not exist in MS SQL Server, nor 'void' datatype for NULL literal. They are used internally. IMPORTANT: The order of these datatypes is important AND SHOULD NOT BE CHANGED, as these values are used when decorating operators to find the "winning" datatype among multiple operands.

E.g.    10 + 12.3        When an "int" and a "numeric" are added, the "int" operand is cast to a "numeric" datatype, and the "+" operator will add two "numeric" values.

CATEGORY_MAP is a static map, to get the string representation of a Category_t.

var Check_column_not_null func(context *Context, gtabledef *GTabledef, column_name string) *Error

Check_column_not_null contains a function defined in rsql/csr, but used in rsql/dict. This variable is created here to avoid circular import issue.

var Execute_basicblock func(context *Context, basicblock *Basicblock) (retval int64, rsql_err *Error)

pointer to vm.Execute_basicblock, needed to avoid circular import. Indeed, rsql/csr cursors need to call this function to evaluate ON and WHERE clauses, but vm already imports csr.

var Fill_index_with_records func(context *Context, table_qname Object_qname_t, gtabledef *GTabledef, indexdef *Tabledef) *Error

Fill_index_with_records contains a function defined in rsql/stmt, but used in rsql/dict. This variable is created here to avoid circular import issue.

var G_BATCH_INSERTS_MAX_COUNT int

var G_BATCH_TEXT_MAX_SIZE int

If too large, there is a risk that too much memory will be used by the batch for all the Token_primaries, which size is more than 300 bytes. This value is sent to the client, which stores it in session.server_batch_text_max_size when connection is established.

rsql collation name to golang collation name.

NOTE: "bs_cyrl" is mapped to "bs-Cyrl". Notice the underscore, replaced by a hyphen in the mapping. Same for "fr_ca" etc.

This map is created from the list of locales returned by function Supported(), in package "code.google.com/p/go.text/collate".

VERSION OF COLLATION DATA:
      In file code.google.com/p/go.text/collate/tables.go, it is written that the collation table was created by running:
      maketables -root=http://unicode.org/Public/UCA/6.2.0/CollationAuxiliary.zip -cldr=http://www.unicode.org/Public/cldr/23/core.zip

      In 2015, all packages in code.google.com/p/ have been migrated to golang.org/x/.

      In file golang.org/x/text/collate/collate.go, it is written:
      go:generate go run maketables.go -cldr=23 -unicode=6.2.0

If a collation is not listed here, like italian "it", it means it is the same as "en" collation.

TODO
THIS PROBLEM WILL BE SOLVED WHEN TABLES WILL BE CREATED WITH CLDR VERSION 25. WE JUST HAVE TO WAIT.
Indeed, in cldr release 25, all missing collations like "it" have been added, with empty body:
In http://unicode.org/cldr/trac/browser/tags/release-25/common/collation/it.xml, as it is written "The root collation order is valid for this language".

func Get_collator(collation_string string) (*collate.Collator, *Error)

get_collator creates a new Collator from string.

collation must be a supported locale, with a suffix like "_cs_as", or an error is returned.

2014.03.19 text/collate package is still buggy.

Normally, with a collator with Strength = colltab.Primary and CaseLevel = true, 'role' == 'rôle', because comparison is accent insensitive and case sensitive.
But text/collate.CompareString('role', 'rôle') gives -1.

That's why we only allow Primary, Secondary and Tertiary Strength. CaseLevel setting is not used, as it is buggy.

func New_Error

func New_Error(category_id Category_id_t, message_id Message_id_t, severity_id Severity_id_t, message_args ...interface{}) *Error

func Normalize_collation

func Normalize_collation(collation_str string) (string, *Error)

Normalize_collation returns the normalized version of a collation string. For e.g. "French_cs_as", "FR_CS_AS", the string "fr_cs_as" is returned. For "French_CA_ci_ai", "fr_ca_ci_ai" is returned.

Returns error if invalid collation.

func (*Error) Error

func (rsql_err *Error) Error() string

func (*Error) Error_short

func (rsql_err *Error) Error_short() string

func (*Error) More_info

func (rsql_err *Error) More_info(more_fmt_string string, more_args ...interface{})

E.g. when a parsing error occurs during BULK INSERT, it is nice to have also the line number of import file which caused the error.

type GTabledef

type GTabledef struct {
	Gtblid int64

	Gdbid                int64
	Gschid               int64
	Gtable_name          string // table name
	Gtable_name_original string // original cased, for display usage

	Base     *Tabledef            // CLUSTERED base table (for base table, Td_tblid == Td_base_gtblid == Gtblid)
	Indexmap map[string]*Tabledef // contains all NONCLUSTERED index tables
	Colmap   map[string]*Coldef

	Identity_seed      int64

func (*GTabledef) Has_IDENTITY_column

func (gtabledef *GTabledef) Has_IDENTITY_column() bool

func (*GTabledef) Modify_native_key

func (gtabledef *GTabledef) Modify_native_key(index_name string, index_name_original string, index_type Td_index_type_t, keyname_list []string) *Error

Modify_native_key changes the native key of gtabledef. It modifies all indexes, so all Tabledefs in gtabledef are modified.

*** IMPORTANT *** If error, gtabledef is in a garbage state. YOU MUST ALWAYS PASS A CLONE OF gtabledef AS RECEIVER, so that you can discard it if the function returns an error.

                  Also note that the tblid of all Tabledefs are not changed, but they are useless, as CREATE TABLE will overwrite them with new values.

func (*GTabledef) Primary_key

func (gtabledef *GTabledef) Primary_key() (tabledef_pk *Tabledef)

	Td_status Td_status_t // TD_STATUS_BEING_CREATED, TD_STATUS_VALID, TD_STATUS_BEING_DROPPED, TD_STATUS_CORRUPTED
}

Description of physical storage, for a table or index.

A nonclustered index is a real index, and is physically like a normal table :
  - native key is made of columns from the index key list. If not PRIMARY KEY or UNIQUE, ROWID column is included, as native key must be unique.
  - it is followed by the native key columns of the base table, unless the column already exists in native key of this index.

The clustered index is the base table, which contains all columns. Records are physically sorted by the native key.
  - native key is made of columns from the index key list. If not PRIMARY KEY or UNIQUE, ROWID column is included, as native key must be unique.

PERMANENT TABLES and FLASHTABLES

If Td_tblid >= 0: ordinary table
                  permanent which definition (GTabledef) is stored in master.db.
                  Use wcache.wpc_journal for modifications, which are copied at commit to the table data file.

If Td_tblid <  0: flashtable (variable table (DECLARE @a TABLE) or grouptable or sorttable).
                  temporary table, which is created during parsing stage, and deleted when batch terminates.
                  Td_tblid is unique only in the batch.
                  GTabledef for variable table (not grouptable nor sorttable) is put in parser.Temptable_bag during batch duration.
                  Use wcache.wpc_flashjournal, and no table data file. Flashtables are never committed, but only live in the logfile.
                  In GTabledef and Tabledef, Td_dbid is trashdb and Td_schid is dbo. This is because some functions could use these info for display usage, but it should not happen.
                       So, there is no need to lock trashdb nor the flashtable when a flashtable is used.

type Tuple

type Tuple []byte

Tuple is a serialized Row, stored on disk as a stream of bytes.

Its structure is:

     offset of field 0                 uint16    number of fields == offset of field 0 / 2 - 1
     offset of field 1                 uint16
     ...
     offset of field n-1               uint16
     offset of sentinel field n        uint16    this field n doesn't really exists, This offset value it just one byte past the end of field n-1. It is the length of the tuple, in bytes.

     serialized value of field 0       bunch of bytes, starting at "offset of field 0"
     ...                               bunch of bytes
     serialized value of field n-1     bunch of bytes, starting at "offset of field n-1"

The illustration of the layout is:
      ======================= header of offsets ==================----------------------------- data ------------------------------------
      | offset 0 | offset 1 | ... | offset n-1 | offset sentinel | serialized field 0 | serialized field 1 | ... | serialized field n-1 |
      ============================================================-----------------------------------------------------------------------
