在SQLDeveloper（oracledb）中执行该语句时，该语句非常有效。

select id,name,street,post_code,town,phone_number,web_site,email,short_description,    
description, latitude,longitude,external_id,facebook_page_id 
FROM poi WHERE ( 6371 * acos( cos( radians( 5 ) ) * cos( radians( latitude ) ) * cos(    
radians( longitude ) - radians( 3 ) ) + sin( radians( 5 ) ) * sin( radians( latitude ) ) ) ) <= 1000000 ; 

如果我通过java查询执行它：

if (requestedDistance) {
String raw = "SELECT         
id,name,street,post_code,town,phone_number,web_site,email,short_description, description,             
latitude,longitude,external_id,facebook_page_id"
+ " FROM poi WHERE ( 6371 * acos( cos( radians( "
+ posLatitude.toString()
+ " ) ) * cos("
+ " radians( latitude ) ) * cos( radians( longitude ) -"
+ " radians( "
+ posLongitude.toString()
+ " ) ) + sin( radians( "
+ posLatitude.toString()
+ " ) ) * sin( radians( latitude"
+ " ) ) ) ) <= "
+ thresholdDistance.toString() + " ;";

日志中出现以下异常：

从日志文件复制语句并在sqldeveloper中再次执行它将返回有效的输出。。

谢谢你的帮助！
