[tarantool-patches] [PATCH v4 5/5] sql: check new box.sql.execute()
imeevma at tarantool.org

Fri Nov 30 22:01:26 MSK 2018
This commit checks that new implementation of box.sql.execute() is
able to pass all tests. This is temporary commit and should be
dropped later. Even though this commit is temporary it shows that
this patch-set should be pushed after patch for issue #3832.
Needed for #3505
