be reordered. [forum:/forumpost/6650cd40b5634f35|forum post 6650cd40b5634f35].
This is probably more strict that necessary to get correct behavior,
but for the first release that supports RIGHT/FULL JOIN it is perhaps better
to be correct than fast.  A less strict constraint might be to prohibit
FROM-clause terms that originate on the left side of a RIGHT JOIN from
crossing from the right side to the left side of a LEFT JOIN.  Revisit this
later.

compatibility, unless there is a RIGHT or LEFT join someplace in the query,
in which case there is no legacy to support.

43baa1de76 Do not run the subroutine that materializes a view or subquery until just 
before the materialization is actually needed, so that if the materialization
turns out to never been needed, unnecessary work can be avoided.

71eacead76 WASM: removed the in64-related bindings, as MDN says that calling a wasm function which has an int64 type in its signature will currently throw because JS has no 64-bit integer support. Those bindings now use doubles and simply hope that the user doesn't exceed their integer precision (2^53-1, approx 9 quadrillion).

f6868562ce Implemented Stmt.get() and friends for WASM OO #1 wrapper. Added basic tests for prepare/step/get. Restructured module init output to introduce only 1 global-scope symbol instead of 2.

40b5b19a0f WASM: added bindings for sqlite3_compileoption_get/used(), moved OO #1 into sqlite3-api.js since it can only be used from the same thread as that API and separating them complicates client-side use. Started adding test utilities and tests for the OO1 API.

b800bd63aa Use the newer OP_BeginSubrtn opcode instead of OP_Integer to start the 
subroutine used to matrialize a view.  This does not change execution but
does make the byte code a little easier to read.
