Moritz Eyssen 9701403ff5 Fix multi-threaded parsing (#110)
This should fix multi-threaded parsing. Not a clean solution, I am guessing the following block should be a single, state-less pattern? @mrks

```
\'                          { BEGIN singlequotedstring; strbuf = std::stringstream{}; }
<singlequotedstring>\'\'    { strbuf << '\''; }
<singlequotedstring>[^']*   { strbuf << yytext; }
<singlequotedstring>\'      { BEGIN 0; yylval->sval = strdup(strbuf.str().c_str()); return SQL_STRING; }
<singlequotedstring><<EOF>> { fprintf(stderr, "[SQL-Lexer-Error] Unterminated string\n"); return 0; }
```

Anyway, the following hyrise playground does not crash anymore, so Toni should be able to work with this for the time being.

```c++
#include <iostream>
#include <thread>

#include "types.hpp"
#include "tpch/tpch_queries.hpp"
#include "SQLParser.h"

using namespace opossum;  // NOLINT

int main() {
  std::vector<std::thread> threads;

  for (size_t t = 0; t < 200; ++t) {
    threads.emplace_back([&]() {
      for (size_t p = 0; p < 10'000; ++p) {
        hsql::SQLParserResult result;
        hsql::SQLParser::parse(tpch_queries.at(19), &result);
        std::cout << "Parsing " << p << " is valid: " << result.isValid() << std::endl;
      }
    });
  }

  for (auto& thread : threads) {
    thread.join();
  }

  return 0;
}
```

javrucebo cdd271490b Allow more variations of LIMIT/OFFSET
In addtion to already supported LIMIT/OFFSET variants allow more to be parsed

Legacy:
  - LIMIT int
  - LIMIT int OFFSET int

Enhancement:
  - OFFSET int             (no limit)
  - LIMIT ALL              (no limit)
  - LIMIT NULL             (no limit)
  - LIMIT ALL OFFSET int   (no limit, but offset)
  - LIMIT NULL OFFSET int  (no limit, but offset)

Also ensures negative limits / offsets are set to kNoLimit/kNoOffset

javrucebo 66688f7199 Adjust Table Join Types
Consolidate LeftOuter/Left and RightOuter/Right as they are
by definition the same.
Similar consolidate FullOuter/Outer/Full ... with Outer (as in the
parser) not part of standard, but "full" missing. Allowing all three.

This commit potentially breaks other programs as kJoinLeftOuter and kJoinRightOuter
are eliminated

javrucebo 66804a6281 Allow '==' to be parsed as equal operator in expressions.
SQLite allows for this and it is in the same spirit as allowing both != and <>
for non equality.

Moritz Eyssen 074bce4d90 dix and adapt casecasewhen 2018-01-17 13:11:39 +01:00
javrucebo daf8fe7a45 Changing Grammar to extend CASE WHEN statement:
- allow multiple WHEN statements
- allow for syntax like `CASE x WHEN 1 THEN 2 WHEN 3 THEN 4 ELSE 5 END`
NOTE: This changes also the way the CASE operator is stored:
- CASE [expr] exprList [ELSE expr2] END
- exprList holds each of the WHEN statements with:
  expr := WHEN, expr2 := THEN

Added also tests in test/select_tests.cpp
and adapted the existing one to reflect the new storage
