[tarantool-patches] [PATCH v2] sql: prohibit negative values under LIMIT clause
Stanislav Zudin

Tue Feb 5 11:56:36 MSK 2019
If LIMIT or OFFSET expressions can be casted to the
negative integer value VDBE returns an error.
If expression in the LIMIT clause can't be converted
into integer without data loss the VDBE instead of
SQLITE_MISMATCH returns SQL_TARANTOOL_ERROR with
message "Only positive numbers are allowed in the
LIMIT clause". The same for OFFSET clause.
Closes #3467
