最满意答案
SELECT case when barcode='your_value' then 1 else 0 end as matches_bar_code , col1 , col2 , col3 , col4 FROM stuff WHERE barcode = '123123' OR product like '%123123%'
不要
select *
。 不好的做法。 列出您需要的列。SELECT case when barcode='your_value' then 1 else 0 end as matches_bar_code , col1 , col2 , col3 , col4 FROM stuff WHERE barcode = '123123' OR product like '%123123%'
Don't do
select *
. Bad practice. List the columns you need.
