| 5 | In the extended BNF expression below white space is explicitly |
| 6 | denoted <WS>. Literals are quoted as in 'literal', while \' |
| 7 | indicates apostrophe character. |
| 8 | |
| 9 | Basic non-terminals used: |
| 10 | |
| 11 | <Name> ::= <Letter> { <NameEnd> } |
| 12 | <NameEnd> ::= ( <Letter> | <Digit> | '_' ) { <NameEnd> } |
| 13 | <Letter> ::= 'a' | 'b' | ... | 'z' | 'A' | 'B' | ... | 'Z' |
| 14 | <Digit> ::= '0' | '1' | ... | '9' |
| 15 | <Value> ::= <Integer> | <Real> | <Time> | \'<String>\' |
| 16 | <Time> ::= See SOI TN 94-116 |
| 17 | <Value_Increment> ::= <Integer> | <Real> | <Time_Increment> |
| 18 | <Time_Increment> ::= <Real><Time_Increment_Specifier> |
| 19 | <Time_Increment_Specifier> ::= 's' | 'm' | 'h' | 'd' |
| 20 | |
| 21 | |
| 22 | Main rules: |
| 23 | |
| 24 | <RecordSet> ::= <SeriesName> <RecordSet_Filter> |
| 25 | <SeriesName> ::= <Name> |
| 26 | |
| 27 | <RecordSet_Filter> ::= '[' ( <RecordQuery> | <RecordList> ) ']' |
| 28 | { <RecordSet_Filter> } |
| 29 | |
| 30 | <RecordQuery> ::= '?' <SQL where clause> '?' |
| 31 | |
| 32 | <RecordList> ::= ( ':'<RecnumRangeSet> | |
| 33 | {<Primekey_Name>'='}<PrimekeyRangeSet> ) |
| 34 | <RecnumRangeSet> ::= <IndexRangeSet> |
| 35 | <Primekey_Name> :: <Name> |
| 36 | |
| 37 | <PrimekeyRangeSet> ::= ( <IndexRangeSet> | <ValueRangeSet> ) |
| 38 | |
| 39 | <IndexRangeSet> ::= ( '#' <Integer> | |
| 40 | '#' <Integer> '-' '#' <Integer> { '@' <Integer> } | |
| 41 | '#' <Integer> '/' <Integer> { '@' <Integer> } |
| 42 | ) { ',' <IndexRangeSet> } |
| 43 | |
| 44 | <ValueRangeSet> ::= ( <Value> | |
| 45 | <Value> '-' <Value> { '@' <Value_Increment> } | |
| 46 | <Value> '/' <Value_Increment> { '@' <Value_Increment> } |
| 47 | ) { ',' <ValueRangeSet> } |
