Javascript Alasql:UNION（或UNION ALL）仅给出表1中的结果

使用alasql在GROUP BY查询中使用UNION或UNION ALL时，仅检索表1中的结果

相反，运行单独的查询会输出正确的结果

看到这把小提琴了吗

刚发现：好像是个虫子

看

:

var data= [
{"label":"transport - car","value":800},
{"label":"airplane","value":234},
{"label":"train","value":500},
{"label":"glider","value":123},
{"label":"transport - motorbike","value":50},
{"label":"transport - bike","value":150}
];


var query1 = alasql('' +
        'SELECT \'transport\' AS label, SUM(CAST([value] AS INT)) AS [value] ' +
        'FROM ? ' +
        'WHERE label LIKE \'%transport%\' ' +
        'GROUP BY \'transport\' ' +
        '',
[data]);

 var query2 = alasql('' +
        'SELECT label, SUM(CAST([value] AS INT)) AS [value] ' +
        'FROM ? ' +
        'WHERE label NOT LIKE \'%transport%\' ' +
        'GROUP BY label' +
        '',
[data]);

var queryUnion = alasql('' +
        'SELECT \'transport\' AS label, SUM(CAST([value] AS INT)) AS [value] ' +
        'FROM ? ' +
        'WHERE label LIKE \'%transport%\' ' +
        'GROUP BY \'transport\' ' +
        'UNION ALL ' + //or UNION, same result!
        'SELECT label, SUM(CAST([value] AS INT)) AS [value] ' +
        'FROM ? ' +
        'WHERE label NOT LIKE \'%transport%\' ' +
        'GROUP BY label' +
        '',
[data, data]);


$("#res").html("<br/>UNION IS WRONG (length is correct, but query2 results are missing!!!)!<br/>" + JSON.stringify(queryUnion) + " LENGTH: " + queryUnion.length);

$("#info").html("<br/>Query1 is correct:<br/>" 
+ JSON.stringify(query1) 
+ " LENGTH: " + query1.length
+ "<br/><br/>Query2 is correct<br/>" + JSON.stringify(query2) 
+ " LENGTH: " + query2.length);
