Over a prescribed timeinterval (nominally one hour), an array of inferred wind velocities,indexed by height, with typical vertical resolutionsof 250 meters to altitude below seven kilometers (see sample data at left). Rather than air, the solar wind is a stream of charged particles-a plasma-ejected from the upper atmosphere of the Sun at a rate of 400 kilometers per second (890,000 mph). It means that MySQL reads the data from the table present in the first row, then finds the matching row in the table present in the second row, and so on. For example, If it is optimized to fetch all the required columns from an index directly using the index scan then MySQL can use the index scan instead of the data row scan. It shows all the possible indexes from which MySQL can use the index to find the rows in the table. If the table is not partitioned then it shows a NULL value, or it may be possible that this column is not present in the output result if none of the tables is partitioned.

So it may be possible that none of the keys is used. We can use EXPLAIN to find the keys used in the query and how we can optimize them.

Keep seeds or potted plants readily available in case of plant loss. Touching any of them will result in a loss of life, and the game is over when your lose your last life. This blog is about how we can get useful information from the result of EXPLAIN. But this key is not dependent on the order of the table in the output result i.e it does not depend on the order of the table in which MySQL process the query. 1.2 Subquery: Any select query used in another select query but not in the FROM clause. The output of ‘explain’ contains information on each table used in the query and in the order in which MySQL read the tables while processing the query. When we write complex queries, understanding the effect of the query is essential. Sometimes poorly written complex queries can be the reason for a database's poor performance. Some used to be simple, and some queries used to be complex that includes even more than 4 - 5 tables. It's no secret.

It shows the actual key that is used to find the rows in the table. This column shows the types of select.
