I am making an app with many database operations. Since SQLite caches data, in my applicationDidReceiveMemoryWarning method, I am closing the database and opening it again to delete the cached data.

When the do this, I get this error

*** Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘Error: failed to open database with message ‘not an error’.’

Here’s the code I am using to close the database and open again where database is of type sqlite3* [MySQLInter finalizeStatements];

 if(sqlite3_close(database) == SQLITE_OK){  //open again NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);  NSString *documentsDirectory = [paths objectAtIndex:0];  NSString *path = [documentsDirectory stringByAppendingPathComponent:@'mydb.sql'];       if(sqlite3_open([path UTF8String], &database) != SQLITE_OK){           NSAssert1(0, @'Error: failed to open database with message '%s'.', sqlite3_errmsg(database));  }   }   else{  NSAssert1(0, @'Error: failed to close database on memwarning with message '%s'.', sqlite3_errmsg(database));   }

How to avoid this?

  1. Are you sure you don’t mean ‘!= SQLITE_OK’ on the sqlite3_open call?
