mysql_stmt_bind_param(3)

💅 NAME 💅

mysql_stmt_bind_param — bestie, this is the one that binds parameters to a prepared statement. It's from MariaDB Connector/C, and it's literally the moment your placeholders get their little outfits on. 👑

✨ SYNOPSIS ✨

#include <mysql.h>

my_bool mysql_stmt_bind_param(MYSQL_STMT * stmt,
                              MYSQL_BIND * bind);

🦋 DESCRIPTION 🦋

Okay so picture this: you already handed your statement to mysql_stmt_prepare(3), and now it's just sitting there with all these sad empty parameter markers like ? ? ? going "girl, where's my data". Not anymore. 🎀

This function binds variables for the parameter markers in that prepared statement — the one you passed to mysql_stmt_prepare(3). You're basically doing matchmaking: each variable in your MYSQL_BIND array gets paired up with a parameter marker. 💖

Return value, listen up:

• zero → success, we ate, no crumbs ✨
• non-zero → failure, it's giving tragedy 😭

🌸 PARAMETERS 🌸

• stmt — a statement handle, which was previously allocated by mysql_stmt_init(3). You can't just roll up with a random pointer, bestie, it has to be one you actually made.
• bind — an array of MYSQL_BIND structures. And the size of this array must be equal to the number of parameters. No more, no less. It's giving "exact headcount at the party" energy. 🎀

👑 NOTES 👑

• The number of parameters can be obtained by mysql_stmt_param_count(3). That's your little count-keeping bestie, always knows how many seats are at the table.
• If the number of parameters is unknown — for example when using mariadb_stmt_execute_direct(3) — then the number of parameters have to be specified with the mysql_stmt_attr_set(3) function. Yeah, you have to tell it. It's not psychic, it's a C library. 🫶
