问题描述
我正在使用弹性搜索7.6.2版本。将参数传递给在kibana中不起作用的查询。当我尝试添加参数查询时,如果我们尝试使用参数查询,将无法在kibana开发工具中正常工作。
POST /_sql?format=txt
{
"query": "SELECT count(*) as aa from student where st_category = ?","params": [
39
]
}
```
{
"error" : {
"root_cause" : [
{
"type" : "x_content_parse_exception","reason" : "[5:3] [params] Expected START_OBJECT but was: END_ARRAY"
}
],"type" : "x_content_parse_exception","reason" : "[5:3] [sql/query] Failed to parse field [params]","caused_by" : {
"type" : "x_content_parse_exception","reason" : "[5:3] [params] Expected START_OBJECT but was: END_ARRAY"
}
},"status" : 400
}
解决方法
转载于7.6.0群集上,但不适用于我的7.9+ 此功能首先出现在7.7。 因此,不幸的是,如果要使用群集,则必须对其进行升级。
