SurrealQL Functions

SurrealDB ships hundreds of built-in functions grouped into namespaces (string::, array::, math::, type::, …). Function names and signatures change between releases, so the authoritative, version-current source is the SurrealQL tooling rather than memory:

• surrealql-language-server (LSP) — completions for built-in functions, hover with type info and function signatures, and signature help.
• surrealql-tree-sitter — the grammar the LSP parses with (targets SurrealDB v3+).

For mapping any function to authoritative documentation, see references/catalog.md.

When to use this skill

• Looking up which built-in function does what, or its exact arguments
• Getting live completions, hover, and signature help for .surql files
• Confirming a function exists / has the expected signature in the installed SurrealDB version (avoids emitting renamed or removed functions)
