iphone - how to inserting data after completion of inserting and updating the data -

i developing 1 application. in iam facing problem @ inserting info database. first insert , update performed well. after updating if want perform insert operation app crashed. code inserting , updating below

+(bool)update:(calendarinfo*)clinfo { nsstring *query = [nsstring stringwithformat:@"update abc set = '%@' b =%d , c=%d",clinfo.a,clinfo.b,clinfo.c]; sqlite3_stmt *ststatement; if(sqlite3_prepare_v2(database, [query utf8string], -1, &ststatement, nil)==sqlite_ok) { if(sqlite_done == sqlite3_step(ststatement)) nsassert1(0, @"error while inserting data. '%s'", sqlite3_errmsg(database)); else nslog(@"updation successful"); } homecoming 0; } +(bool)insert:(calendarinfo*)clinfo{ sqlite3_stmt *addstmt = nil; sqlite3 *contactdb; nsarray *docpatharr = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes); nsstring *destpath = [nsstring stringwithformat:@"%@/example.sqlite",[docpatharr objectatindex:0]]; if (sqlite3_open([destpath utf8string], &contactdb)==sqlite_ok) { nsstring *query2 = [nsstring stringwithformat:@"insert abc(c,b,a) values(%d,%d,'%@')",clinfo.c,clinfo.b, clinfo.a]; if(sqlite3_prepare_v2(database, [query2 utf8string], -1, &addstmt, null) != sqlite_ok) nsassert1(0, @"error while creating add together statement. '%s'", sqlite3_errmsg(database)); } if(sqlite_done != sqlite3_step(addstmt)) nsassert1(0, @"error while inserting data. '%s'", sqlite3_errmsg(database)); else nslog(@"insertion successful"); sqlite3_reset(addstmt); homecoming 0; }

so please tell me how solve problem.

from limited code you've posted, think reply has have two different sqlite3 instances here. intentional?

you phone call sqlite3_open([destpath utf8string], &contactdb);

and effort error result off sqlite instance:

sqlite3_errmsg(database)

either utilize database or contactdb , should set.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
