java 的 Oracle SODA API - 异常 - 缺少右括号
Oracle SODA API for java - Exception - missing right parenthesis
我正在为 JAVA 使用 Oracle SODA API。我正在使用 oracle 12c 数据库。我正在尝试使用字段上的 desc 排序从集合中获取所有记录。
我写了这样的查询，
{ "$query" : {}, "$orderby" : { "LmCreatedOn" : -1}}
这是java代码，
// connection code goes above
final OracleDocument document = db.createDocumentFromString("{ \"$query\" : {}, \"$orderby\" : { \"LmCreatedOn\" : -1}}");
final OracleCursor cursor = db.openCollection(SC_LMS_ADMIN_COURSE).find().filter(document).getCursor();
List<JsonNode> listDto = new ArrayList<JsonNode>();
while(cursor.hasNext()) {
final OracleDocument doc = cursor.next();
listDto.add(JacksonUtils.getObjectMapper().readTree(doc.getContentAsString()));
}
但是我遇到了一个例外，

我通过以下方式解决了这个问题，
If you use Oracle Database Release 12c (12.1.0.2) then you must specify either $scalarRequired or $lax; otherwise a syntax error is raised.
因为我使用的是 Oracle 数据库版本 12c (12.1.0.2)。我在没有 $scalarRequired 的情况下使用查询 json。这就是它抛出语法错误的原因。
更新后的查询是，
{ \"$query\": {}, \"$orderby\" : { \"$fields\" : [{ \"path\" : \"LmCreatedOn\", \"datatype\" : \"varchar2\", \"order\" : \"desc\"}], \"$scalarRequired\" : true }}
这里我也根据oracle doc更新了查询格式。我提供了一些额外的 fields 和额外的细节。此功能出现在最新 soda jar 1.1.0
