Inconsistent results when limiting select to specific columns

[sanketsarang]

In version 1.7.10, it is observed that when limiting a select to specific columns, the database occasionally misses a few records in the response.

The following are logs for the same query fired twice on the same table. The query was expected to respond with 2 records on both occasions.

blobcity>sql test: select col1, col2 from test.test
{"p":[{"col2":2,"col1":1}],"time(ms)":24,"ack":"1","rows":1}
blobcity>sql test: select col1, col2 from test.test
{"p":[{"col2":4,"col1":2},{"col2":2,"col1":1}],"time(ms)":3,"ack":"1","rows":2}

However, the following queries deliver consistent results
select col1 from test.test
select * from test.test
