使用sqlite3创建数据库

创建数据库

#include <stdio.h>
#include <stdlib.h>
#include <sqlite3.h> 

static int callback(void *NotUsed, int argc, char **argv, char **azColName){
int i;
for(i=0; i<argc; i++){
printf("%s = %s\n", azColName[i], argv[i] ? argv[i] : "NULL");
   }
printf("\n");
return 0;
}

int main(int argc, char* argv[])
{
   sqlite3 *db;
char *zErrMsg = 0;
int  rc;
char *sql;

/* Open database */
   rc = sqlite3_open("test.db", &db);
if( rc ){
fprintf(stderr, "Can't open database: %s\n", sqlite3_errmsg(db));
exit(0);
   }else{
fprintf(stdout, "Opened database successfully\n");
   }

/* Create SQL statement */
   sql = "CREATE TABLE COMPANY("  \
"ID INT PRIMARY KEY NOT NULL," \
"NAME TEXT NOT NULL," \
"AGE INT NOT NULL," \
"ADDRESS CHAR(50)," \
"SALARY REAL );";

/* Execute SQL statement */
   rc = sqlite3_exec(db, sql, callback, 0, &zErrMsg);
if( rc != SQLITE_OK ){
fprintf(stderr, "SQL error: %s\n", zErrMsg);
      sqlite3_free(zErrMsg);
   }else{
fprintf(stdout, "Table created successfully\n");
   }
   sqlite3_close(db);
return 0;
}

编译

gcc -o main test.c -l sqlite3
// * 链接 sqlite3 库

输出
