func Infer ¶

func Infer(q *pluginv1.Query, cat *irv1.Catalog, d *catalog.Diagnostics)

Infer mutates q by:

1. Walking the AST to collect ParameterRef nodes → QueryParameter entries.
2. Attempting shallow type inference for parameters by examining operator operands — if a param appears beside a resolved ColumnRef, the param inherits the column's type.
3. For SELECT queries, resolving SelectTarget nodes to QueryColumn entries.

Unresolvable items produce a diagnostic but never a panic.

func ParseQueries ¶

func ParseQueries(sql, sourceFile string) ([]*pluginv1.Query, error)

ParseQueries scans sql for named query blocks, parses each, and returns the resulting []*pluginv1.Query.

A query block begins with a header comment:

-- name: QueryName :command

and extends until the next header (or EOF). If a body fails to parse it is silently skipped; the caller may emit a diagnostic.
