- [ ] sql or expression
- [ ] equal(=) support
- [ ] not equal(!=) support
- [ ] gt(>) support
- [ ] gte(>=) support
- [ ] lt(<) support
- [ ] lte(<=) support
- [ ] sql in (eg. id in (1,2,3) ) expression
- [ ] sql not in (eg. id not in (1,2,3) ) expression
- [ ] paren bool support (eg. where (a=1 or b=1) and (c=1 or d=1))
- [ ] sql like expression (currently use match phrase, perhaps will change to wildcard in the future)
- [ ] sql order by support
- [ ] sql limit support
- [ ] sql not like expression
- [ ] field missing check
- [ ] support aggregation like count(\*), count(field), min(field), max(field), avg(field)
- [ ] support aggregation like stats(field), extended_stats(field), percentiles(field) which are not standard sql function
- [ ] null check expression(is null/is not null)
- [ ] join expression
- [ ] having support
Usage
-------------
`> composer require meysampg/eql`
Demo :
```php
1 order by id desc limit 100,10
";
function main()
{
$dsl = Parser::buildFrom($sql);
print_r(json_encode($dsl));
}
```
will produce :
```json
{
"query": {
"bool": {
"must": [
{
"match": {
"a": {
"query": "1",
"type": "phrase"
}
}
},
{
"match": {
"x": {
"query": "三个男人",
"type": "phrase"
}
}
},
{
"range": {
"create_time": {
"from": "2015-01-01T00:00:00+0800",
"to": "2016-01-01T00:00:00+0800"
}
}
},
{
"range": {
"process_id": {
"gt": "1"
}
}
}
]
}
},
"from": 100,
"size": 10,
"sort": [
{
"id": "desc"
}
]
}
```
If your sql contains some keywords, eg. order, timestamp, don't forget to escape these fields as follows:
```
select * from `order` where `timestamp` = 1 and `desc`.id > 0
```
