How to get record from a database table using parameterized SELECT query in SQLite in C programming | C programming
We will get records from the employee table using source code and print all records on the console screen.
#include <sqlite3.h>
#include <stdio.h>
#include <string.h>
int main(void)
{
sqlite3* db_ptr;
sqlite3_stmt* stmt;
char* errMesg = 0;
int ret = 0;
ret = sqlite3_open("MyDb.db", &db_ptr);
if (ret != SQLITE_OK) {
printf("Database opening error\n");
}
char sql_stmt[64];
strcpy(sql_stmt, "SELECT * FROM Employee where eid=");
strcat(sql_stmt, "201");
ret = sqlite3_prepare_v2(db_ptr, sql_stmt, -1, &stmt, 0);
if (ret != SQLITE_OK) {
printf("\nUnable to fetch data");
sqlite3_close(db_ptr);
return 1;
}
printf("Employee records\n");
while (sqlite3_step(stmt) == SQLITE_ROW) {
printf("%s %s %s\n", sqlite3_column_text(stmt, 0), sqlite3_column_text(stmt, 1), sqlite3_column_text(stmt, 2));
}
sqlite3_finalize(stmt);
sqlite3_close(db_ptr);
return 0;
}
