Some basic SQL (structured query language) queries are regarding how to be more efficient and productive as you have to have a detailed knowledge of how to use the structure of the database for it to be useful. Queries generally involve basic formatting of the system and how to use it.
The basic parts of a SQL Select query are: SELECT column names FROM table name WHERE conditions ORDER BY column names The basic parts of an insert query would be: INSERT INTO table name (VALUES) The basic parts of a delete query would be DELETE FROM table name WHERE conditions The basic parts of an update query would be UPDATE TABLE table name SET column name = value WHERE conditions
You select all columns of all rows from a table with the select * from table_name sql statement. Be careful, this can potentially be a very expensive, poor performance, network intensive type of operation - it is better to select only the columns and rows needed.
An SQL Delete statement is a code used for programming. It allows you to delete a single record or multiple records from a graph or table. These codes can be very useful.
