            MYSQL view is very slow
            Asked 2020-Jan-13 at 01:17

            I have created view by joining multiple tables to avoid loading time on dynamic query. but its giving the same result by taking more time.

            My system configuration is : 8GB RAM i5 Cpu and running this on MySQL 5.7.28. Here is my query :

            Reason to create this type of view is: I have generated this query using php loop. cause I need value as a column to everything should be in one view and i can easily access. in less time but not working. if you can suggest some better way to design view or avoid , generating query with help you php loop would be the best solution. Here is a definition of all tables.

            If we number your view's LEFT JOINS j1-j6, consider the following observations,

            attribute_value tbl has a redundant index, ADD KEY attribute_id (aval_id), should likely be ADD KEY attribute_id (attribute_id), to avoid the redundant index and be available for use in j2.

            attribute tbl has category_id varchar(255) default '0', should likely be DATATYPE category_id int(11) NOT NULL ..., for use in j6 AND add INDEX for the column.

            gemstone_attribute_value tbl has ADD KEY gemstone_abbribute_id (g_aval_id), that would be a redundant index and likely should be DROPPED.

            gemstone_attribute tbl has gemstone_id varchar(255) default '0', should likely be DATATYPE gemstone_id int(11) NOT NULL ..., for use in j5 AND add INDEX for the column,

            Your CASE WHEN lines for gv.gem_attr_id = 'nnn' could be without the single quotes to avoid DATATYPE conversions for every compare since gem_attr_id is INT datatype and save CPU cycles.

            For additional observations/suggestions, please view my profile to make contact.
