SPI_GETARGTYPEID(3)

✨ SPI_GETARGTYPEID(3) — the PostgreSQL 16.15 Documentation page, but make it bestie-coded ✨

Okay so this is the manual page for SPI_getargtypeid, and it's giving “tell me the data type OID for an argument of a statement prepared by SPI_prepare” energy. 💅

---

🌸 NAME 🌸

SPI_getargtypeid — return the data type OID for an argument of a statement prepared by SPI_prepare. No cap, that's literally the whole vibe. 🫶

---

🎀 SYNOPSIS 🎀

Oid SPI_getargtypeid(SPIPlanPtr plan, int argIndex)

---

🦋 DESCRIPTION 🦋

So SPI_getargtypeid returns the Oid representing the type for the argIndex'th argument of a statement prepared by SPI_prepare. First argument is at index zero. Yes bestie, zero is the first one — iconic indexing behavior, honestly. ✨

---

💖 ARGUMENTS 💖

• SPIPlanPtr plan — prepared statement (returned by SPI_prepare) 🌈
• int argIndex — zero based index of the argument 🍓

---

👑 RETURN VALUE 👑

The type OID of the argument at the given index. 💜

If the plan is NULL or invalid, or argIndex is less than 0 or not less than the number of arguments declared for the plan, SPI_result is set to SPI_ERROR_ARGUMENT and InvalidOid is returned. 🚨 Like, read that part twice, bestie — it's the important boundary-check tea. 😭
