I am trying to insert the values in two different tables in a single statement, first insert query in working second query is not working.
sqlite3_stmt * statement= NULL;
const char *dbpath =[databasePath UTF8String];
if (sqlite3_open(dbpath, &mySqliteDB)== SQLITE_OK)
{
for (PostObject * post in in_PostObject)
{
**query**
NSString * postSql =[NSString stringWithFormat:#"insert or ignore into %#_post (postid,data,active) values (\"%#\",?,\"%d\");",tblPrefix,post.post_ID,post.active];
/*Appending First query with second query*/
NSString * insertSQl =[postSql stringByAppendingString:[NSString stringWithFormat:#" insert into %#_forumuser (uid,utype,name) values (1,'parent','javid');",tblPrefix]];
NSLog(#"%#",insertSQl);
const char * insert_stmt=[insertSQl UTF8String];
sqlite3_prepare_v2(mySqliteDB, insert_stmt, -1, &statement, NULL);
sqlite3_bind_text(statement, 1, [post.jsonData UTF8String], -1, SQLITE_TRANSIENT);
if (sqlite3_step(statement)==SQLITE_DONE)
{
success =TRUE;
}
else
{
NSLog(#"DB Error: %s", sqlite3_errmsg(mySqliteDB));
}
}
}
sqlite3_finalize(statement);
sqlite3_close(mySqliteDB);

You need to check the return code from the sqlite3_prepare_v2 to make sure there aren't any problems.
Also you shouldn't need to open and close the database for each statement you want to execute, there you could process them as 2 statements
if(sqlite3_prepare_v2(mySqliteDB, insert_stmt,-1, &statement, NULL) != SQLITE_OK) {
NSLog(#"%s Prepare failure '%s' (%1d)", __FUNCTION__, sqlite3_errmsg(db), sqlite3_errcode(db));
}
