SPI_FNAME(3)

✨ SPI_FNAME ✨

okay bestie, so this is the PostgreSQL 18.6 docs page for SPI_fname, and it's literally one of those tiny little functions that does exactly one thing and does it gorgeously 💅

---

🎀 NAME 🎀

SPI_fname — she tells you the column name for the column number you asked about. that's it. that's the whole job. icon behavior 👑

---

🌸 SYNOPSIS 🌸

char * SPI_fname(TupleDesc rowdesc, int colnumber)

---

💖 DESCRIPTION 💖

so SPI_fname gives you back a copy of the column name of the column you specified. not a pointer into the original, a whole fresh copy, she's generous like that 🫶

and because it's a copy, you can use pfree to release it once you don't need the name anymore. pls do that. don't just leave her hanging in memory forever, that's not the vibe 🙈

---

🦋 ARGUMENTS 🦋

• TupleDesc rowdesc — the input row description. your little map of what's in the row 🗺️
• int colnumber — the column number. and heads up bestie: the count starts at 1, not 0. no zero-indexing here, we're not doing that today ✨

---

⭐ RETURN VALUE ⭐

you get the column name back, slay. but if colnumber is out of range, you get NULL — no name for you 💀

and on error, SPI_result gets set to SPI_ERROR_NOATTRIBUTE. so like, always check, okay? don't just assume she came through 🥺

---

🌈 reminder: it's a copy, so pfree it when you're done. main character energy means cleaning up after yourself 💜

---

and that's the whole page, no notes. this is from the PostgreSQL 18.6 documentation, dated 2026, and it's the SPI_FNAME(3) page — catch you in the next one, mwah 🎀💖✨
