Can help me see the problem?Below is my code Create.sql create table student (No integer primary key autoincrement, Date1 varchar(20), Time varchar(10),Name varchar(10), Id_no integer); insert into student (Date1 , Time, Name, Id_no) values ('10/10/2012', '9.35am', 'Kean Heng', '091021434'); insert.c # include <stdio.h> # include <sqlite3.h> # include <stdlib.h> int main(void) { sqlite3 *conn; sqlite3_stmt *res; int error = 0; int rec_count = 0; const char *errMSG; const char *tail; char sql_lite[900]=" "; char name[50]; int date=0,month=0,year=0,matrix_number=0,number,x; float time =0; error = sqlite3_open("hong.sl3", &conn); if (error) { printf("Can not open database"); } printf("Enter the number of data to be inserted\n"); scanf("%d",&x); for(number=x;number>0;number--) { printf("Enter the name of the student for insert\n"); scanf("%s",name); printf("Enter the date, month, year of the student\n"); scanf("%d%d%d",&date,&month,&year); printf("Enter the time \n"); scanf("%f",&time); printf("Enter the matrix number of the student for insert\n"); scanf("%d",&matrix_number); } sprintf(sql_lite, "insert into student values ('%d/%d/%d','%.2fam','%s',%d);",date,month,year,time,name,matrix_number); error = sqlite3_exec(conn, sql_lite, 0, 0, 0); error = sqlite3_prepare_v2(conn, "select * from student order by No",1000, &res, &tail); if (error != SQLITE_OK) { printf("We did not get any data!"); exit(0); } printf("=======================================\n"); while (sqlite3_step(res) == SQLITE_ROW) { printf("%d|", sqlite3_column_int(res, 0)); printf("%s|", sqlite3_column_text(res, 1)); printf("%s|", sqlite3_column_text(res, 2)); printf("%s|", sqlite3_column_text(res, 3)); printf("%u\n", sqlite3_column_int(res, 4)); rec_count++; } printf("=======================================\n"); printf("We received %d records.\nTotal rows=%d\n", rec_count,SQLITE_ROW); sqlite3_finalize(res); sqlite3_close(conn); return 0; }
  8. How to insert data in the last row but not in the first row using C language.Do sqlite have function that control the row of the insert?I want the sequential row numbers from insert query.Thanks.
  9. #include <stdio.h>#include <sqlite3.h>#include <stdlib.h>static char *createsql = "CREATE TABLE Employee(" "ID INTEGER PRIMARY KEY," "Name VARCHAR(10)," "BadgeID VARCHAR(10));";static char *insertsql = "INSERT INTO Employee VALUES(NULL, 'Danny', '12345');";static char *querysql = "SELECT * FROM Employee;";void main(void){int i,j;int rows, cols;sqlite3 *db;char *errMsg = NULL;char **result;/* Open database file */if (sqlite3_open("my_example.db3", &db, SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE, NULL)){ return ;}/* Build Table */ sqlite3_exec(db, createsql, 0, 0, &errMsg);/* Add a new record */ sqlite3_exec(db, insertsql, 0, 0, &errMsg);/* Get the last insert record's ID */ printf("%d\n", sqlite3_last_insert_rowid(db));/* Get all records in database */ sqlite3_get_table(db , querysql, &result , &rows, &cols, &errMsg);/* List all the data */ for (i=0;i<rows;i++){ for (j=0;j<cols;j++) { printf("%s\t", result[i*cols+j]); } printf("\n");} /* Free table */ sqlite3_free_table(result);/* Close database */ sqlite3_close(db);} Above is the code...When I'm compile it,I get the error in the terminal: hong@ubuntu:~/test$ gcc -lsqlite3 -o sqlite_exp sqlite_exp.csqlite_exp.c: In function ‘main’:sqlite_exp.c:18:1: error: too many arguments to function ‘sqlite3_open’/usr/include/sqlite3.h:2579:16: note: declared heresqlite_exp.c:32:1: warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘sqlite3_int64’ [-Wformat] Can anyone help me point out the correction?thanks...
