How to pass the comma separated string value in sql query?

I create one database related app. In this i create simple database and get the value from database using in in sql query. My problem is there i got the on string like a "2,6,8,9,10" this. first i split this string and store in one arraylist. with out comma. after this arraylist i merge with comma like a 2,6,8,9,10 this. i do all of this very well. i use this string in query to get the value from database. My query is ``` SELECT tm.icon,tm.topic_no,td.topic_id,td.name FROM topicmaster tm ,topicmaster_description td WHERE td.topic_id =tm.topic_id AND td.langid='3' AND tm.oraganisationid ='1' AND td.topic_id in(2,6,8,9,10); ``` this. but when i pass the merge string it`s look like a ``` SELECT tm.icon,tm.topic_no,td.topic_id,td.name FROM topicmaster tm ,topicmaster_description td WHERE td.topic_id =tm.topic_id AND td.langid='3' AND tm.oraganisationid ='1' AND td.topic_id in('2,6,8,9,10'); ``` so i can not run the query because the different of pass value in `in` cause. in above query work fine because it`s like a`in(2,6,8,9,10)` in second it look like a`in('2,6,8,9,10')` so what to do. how to remove this`'` from string? First i split String ``` //getTopicFile ArrayList with public ArrayList<String> getAssignTopicArrayList(String passString) { ArrayList<String> rtnArrayList=new ArrayList<String>(); try { StringTokenizer strTokens = new StringTokenizer(passString,","); while (strTokens.hasMoreElements()) { rtnArrayList.add(String.valueOf(strTokens.nextToken())); } } catch (Exception ex) { ex.printStackTrace(); System.err.println("Error in Fetch ArrayList-->"+ex.toString()); } return rtnArrayList; } //getTopicFile ArrayList with ``` After i merge in New String ``` genHelper.showErrorLog("Assign Topic-->"+chapterAssignTopicName); ArrayList<String> getTopicList=genHelper.getAssignTopicArrayList(chapterAssignTopicName); String passConcat = ""; for (int i = 0; i < getTopicList.size(); i++) { System.out.println("Topic List--->"+getTopicList.get(i)); if(getTopicList.size()==1) { passConcat=passConcat.concat(String.valueOf(getTopicList.get(i))); } else { if(getTopicList.size()-1 == i) { System.err.println("value if --> " + i); passConcat=passConcat.concat(String.valueOf(getTopicList.get(i))); }else { System.err.println("value else--> " + i); passConcat=passConcat.concat(String.valueOf(getTopicList.get(i)).concat(",")); } } } genHelper.showErrorLog("PassConcat String-->"+passConcat); ``` then i got New String and pass in query it` below ``` String topicQuery="SELECT tm.icon,tm.topic_no,td.topic_id,td.name FROM topicmaster tm ,topicmaster_description td WHERE td.topic_id =tm.topic_id AND td.langid='"+LanguageActivity.languageId+"' AND tm.oraganisationid ='"+genHelper.loadPreferences(String.valueOf(R.string.sharePrefin_Login_organizationid))+"' AND td.topic_id in('"+passConcat+"')"; ```
