SQL statements

This section describes the subset of SQL statements and elements.

create-table-statement ::=
  CREATE TABLE base_table_name
  (column_identifier data_type [,
      column_identifier data_type]...)

Important As the data_type in a create_table_statement, applications require a data type from the TYPE_NAME column of the result set returned by SQLGetTypeInfo.

delete_statement_searched ::=
DELETE FROM table_name [WHERE search_condition]

drop_table_statement ::=
DROP TABLE base_table_name

select_statement ::=
    SELECT [ALL | DISTINCT] select_list
    FROM table_reference_list
    [WHERE search_condition]
    [order_by_clause]

Update_statement_searched ::=
    UPDATE table_name
    SET column_identifier = {expression |
        NULL}
    [, column_identifier = {expression |
        NULL}]...
    [WHERE search_condition]

SQL statement elements

base_table_identifier ::= user_defined_name

base_table_name ::= base_table_identifier

boolean_factor ::= [NOT] boolean_primary

boolean_primary ::= predicate | ( search_condition )

boolean_term ::= boolean_factor [AND boolean_term]

character_string_literal :: = "{character}..."

character is any character in the character set of the driver/data source. To include a single literal quote character (') in a character_string_literal, use two literal quote characters ("").

column_identifier ::= user_defined_name

column_name ::= [table_name.]column_identifier

comparison_operator ::= < | > | <= | >= | = | <>

comparison_predicate ::= expression comparison_operator expression

data_type ::= character_string_type

character_string_type is any data type for which the ""DATA_TYPE"" column in the result set returned by SQLGetTypeInfo is either SQL_CHAR or SQLVARCHAR.)

digit ::= 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9

dynamic_parameter ::= ?

expression ::= term | expression {+|-} term

factor ::= [+|-]primary

insert_value ::= dynamic_parameter | literal | NULL | USER

letter ::= lower_case_letter | upper_case_letter

literal ::= character_string_literal

lower_case_letter ::= a | b | c | d | e | f | g |
h|i|j|k|l|m|n|o|p|q|r|s|
t|u|v|w|x|y|z

order_by_clause ::= ORDER BY sort_specification [, sort_specification]...

primary ::= column_name | dynamic_parameter | literal | ( expression )

search_condition ::= boolean_term [OR search_condition]

select_list ::= * | select_sublist [, select_sublist]...

(select_list cannot contain parameters.)

select_sublist ::= expression

sort_specification ::= {unsigned_integer | column_name } [ASC | DESC]

table_identifier ::= user_defined_name

table_name ::= table_identifier

table_reference ::= table_name

table_reference ::= table_name [,table_reference]...

term ::= factor | term {*|/} factor

unsigned_integer ::= {digit}

upper_case_letter ::= A | B | C | D | E | F | G | H|I|J|K|L|M|N|O|P|Q|R|S| T|U|V|W|X|Y|Z

user_defined_name ::= letter[ digit | letter| _ ]...
