buildCopyFromBlobStatement
buildCopyFromBlobStatement(
__namedParameters):RawStatement&object
Defined in: packages/client/src/sync/copy.ts:288
Render the COPY <table> (<columns>) FROM '/dev/blob' WITH (FORMAT text) statement for rows,
together with the COPY TEXT bytes pgwasm must read for it — a RawStatement whose blob
carries the body (narrowed to a non-optional blob: this builder ALWAYS produces one).
This is the ONE implementation of the COPY-from-blob load: the sync applier’s bulk path
(applyMessagesToTableWithCopy) and the public raw seam both call it, so an app-owned table
bulk-loads on exactly the contract the applier is tested against.
Hand it to rawTransaction (to bulk-load inside one local transaction, e.g. delete-then-COPY) or
to rawQuery’s blob option for a single statement. On a worker-attached client the bytes are
TRANSFERRED, not copied — see RawStatement.blob: the buffer is detached after the call.
Tier ③ (ADR-0028 allow-list), exactly as the applier’s copy of this statement was: COPY … FROM '/dev/blob' is pgwasm’s blob-ingest grammar and has NO Drizzle builder form, so the statement text
stays a raw string. Every identifier in it is still derived — the table from getTableConfig, each
column through quoteIdentifier — so nothing in the string is a hand-written identifier.
