回答1:

to get all that have meta_name price and propertyvalue and meta_value 1000 and 10000 respectively, you need to do this.

SELECT * FROM `table` WHERE (meta_name = 'price' and meta_value = '1000') OR (meta_name = 'propertyvalue' and meta_value = '10000')

this will select both from table where meta_name = 'price' and meta_value = '1000' and meta_name = 'propertyvalue' and meta_value = '10000'
