- File src/select.c — part of check-in [3ad687b7] at 2014-02-26 19:05:53 on branch open-only-once — Only run the OP_OpenRead opcodes for a correlated subquery once, on the initial iteration. Keep the cursor open for subsequent runs. This was suppose to be a performance enhancement, but it is difficult to come up with a query where is makes a significant difference. Hence, the change is getting parked in a branch. (user: drh size: 191690)
