Updating views in mysql
A relational database system contains one or more objects called tables.The data or information for the database are stored in these tables. A modern database is an efficient way to organize, and gain access to, large amounts of data.A relational database is able to create relationships between individual database elements, to organize data at a higher level than a simple table of records, avoid data redundancy and enforce relationships that define how the database functions.The other side will vehemently argue that you should avoid this because not all databases support this and the way each supports it is different so your code is less portable.I would start by saying those individuals who are vehemently on one side or the other should open their minds a little.value that was inserted by a client in a different time zone, you will get a value that is not the same as the value stored in the database.As long as you don’t change the time zone, you can get the same column can be automatically initialized to the current timestamp for inserted rows that specify no value for the column.
At this point I assume the reader has successfully installed My SQL and has logon authority in the system.) Start the My SQL command-line application I'll make this one concession to the differences between platforms: NOTE: There's an alternative to telling My SQL which database to use — one simply prepends the database name to each table reference, like this: "database_name.table_name".The fields in a view are fields from one or more real tables in the database.You can add SQL functions, WHERE, and JOIN statements to a view and present the data as if the data were coming from one single table. (Technically, My SQL is a relational database management system (RDBMS).) My SQL represents an excellent introduction to modern database technology, as well as being a reliable mainstream database resource for high-volume applications.
