+// writeTableRecordCollectionDecl writes the PL/SQL declarations needed to
+// define a custom record type and a collection of that record type,
+// based on the schema of the given table.
+//
+// Specifically, it generates:
+//   - A RECORD type (`t_record`) with fields corresponding to the table's columns.
+//   - A nested TABLE type (`t_records`) of `t_record`.
+//
+// The declarations are written into the provided strings.Builder in the
+// correct PL/SQL syntax, so they can be used as part of a larger PL/SQL block.
+//
+// Example output:
+//
+//	TYPE t_record IS RECORD (
+//	  "id" "users"."id"%TYPE,
+//	  "created_at" "users"."created_at"%TYPE,
+//	  ...
+//	);
+//	TYPE t_records IS TABLE OF t_record;

+//   - plsqlBuilder: The builder to write the PL/SQL code into.
+//   - dbNames: The slice containing the column names.
