I have the Database bur error: SQL(query) error or missing database

Question

I created a database there is no problem, I can show it add data manually, but in the if else method it is not adding any value, I can see the values fit to the if method in the log but I think the problem is execSQL method I can not call it.

Near the bottom of second code I marked with the // line

Error:

android.database.sqlite.SQLiteException: near "s": syntax error (code 1): , while compiling: INSERT INTO myTable1(id, FAVCampaignName, FAVCampaigncampaignStartDate, FAVCampaigncampaignEndDate) VALUES(NULL,'Starbucks's','2019-04-01','2019-04-19'); ################################################################# Error Code : 1 (SQLITE_ERROR) Caused By : SQL(query) error or missing database.

                                SQLITEDATABASEFavCampaign.execSQL(SQLiteQueryFavCampaign); //execSQL gives the error

                                Toast.makeText(CampaignActivity.this,"FAV OK", Toast.LENGTH_SHORT).show();

Answer 1

FAVCampaignName contains a single quote so the database thinks the string ends at köy' and does not know what to do with de...

'Starbucks's 2.kahve %50 indirimli'

Either escape all single quotes with a \ or use a parameterized query.
