Functions

func FromContext

func FromContext(ctx context.Context, query string) (*sql.Stmt, bool)

FromContext retrieves a SQL statement from the context chain that matches the given query. It performs a recursive search through the context chain until it finds a matching statement or reaches the end of the chain.

Note: It prevents infinite recursion by checking for self-referential contexts.

func Query

func Query(s *sql.Stmt) string

Query returns the underlying SQL query string from a *sql.Stmt. The offset of the query field is determined at init time using reflection, ensuring both safety and runtime performance.

Note: This is an internal function that relies on the sql.Stmt structure. It will panic during package initialization if the structure changes.

func WithContext

func WithContext(ctx context.Context, stmt *sql.Stmt) context.Context

WithContext creates a new context containing the provided SQL statement. It maintains a chain of contexts, allowing for statement reuse and lookup.
