结果总是假的。这应该是正确的，因为我的观点在（包含在）多边形中。

Answer 1

根据ST_ContainsAPI reference，它需要两个几何图形作为输入。但是在您的情况下，您传递的是文本和几何图形。

ST_Contains(ST_AsText(...),geometri)

相反，您需要使用ST_GeomFromText 再进行一次转换，如下所示：

ST_Contains(ST_GeomFromText(ST_AsText(...)),geometri)

因此，最终查询可能如下所示：

select ST_Contains(ST_GeomFromText(ST_AsText('<replace_with_your_value>')),geometri) As smallinsmall, nama_file,geometri from table_survey;

Answer 2

正如@learningloop 所说，您的查询在语法上是错误的，而且您的坐标也是错误的。该点有坐标：

 POINT(5.55109592209746 95.3190735176197)

但是多边形有

POLYGON((95.3157049187059 5.54820325451167,95.3163919590383 5.54806823349114.......

您在构建多边形或点时显然反转了坐标。

我不知道，是多边形错还是点错了，但是如果你把点的坐标倒过来的话：

POINT(95.3190735176197 5.55109592209746)

ST_contains 查询返回 true：
