Embedding SQLite in a c programm
Embedding SQLite in a c programm
The following program demonstrates how to embed SQLite into a c program.
I compiled the program with MinGW without any problems (Using this makefile)
In order to compile the program, you have to download the SQLite sources (version 3.0.1, the zip file) as well as the following c program (embed_sqlite.c). I don't know how easy or hard it is to compile it with another compiler than MinGW.
The program does the following:
Creates a database (filename: countries.db).
Creates a table in this database (table name: countries).
Inserts many countries with their size and population.
Queries the table for the countries with the most/fewest people/area.
The programm
embed_sqlite.c
#include <string.h>
#include <stdio.h>
#include "sqlite3.h"
sqlite3* db;
int first_row;
int select_callback(void *p_data, int num_fields, char **p_fields, char **p_col_names) {
int i;
int *p_rn = (int*)p_data;
if (first_row) {
first_row = 0;
for(i=0; i < num_fields; i++) {
printf("%20s", p_col_names[i]);
}
printf("\n");
for(i=0; i< num_fields*20; i++) {
printf("=");
}
printf("\n");
}
(*p_rn)++;
for(i=0; i < num_fields; i++) {
printf("%20s", p_fields[i]);
}
printf("\n");
return 0;
}
void select_stmt(const char* stmt) {
char *errmsg;
int ret;
int nrecs = 0;
first_row = 1;
ret = sqlite3_exec(db, stmt, select_callback, &nrecs, &errmsg);
if(ret!=SQLITE_OK) {
printf("Error in select statement %s [%s].\n", stmt, errmsg);
}
else {
printf("\n %d records returned.\n", nrecs);
}
}
void sql_stmt(const char* stmt) {
char *errmsg;
int ret;
ret = sqlite3_exec(db, stmt, 0, 0, &errmsg);
if(ret != SQLITE_OK) {
printf("Error in statement: %s [%s].\n", stmt, errmsg);
}
