 SQL Definition
We define SQL |
SQL - This is a means of managing data in a relational database. There is a SQL standard, and there are also many vendor-specific SQL packages which combine relational databases with tools SQL tools to manage them. Statements in SQL can be used to read or request data from a database, such as, "select * from geek," which would return an entire table of data from the table named "geek." Queries can also be much more complex such as, "select * from geek where name=sam" which would return records from the database where the field "name" was set to "sam." SQL statements can also be used to delete and update data. |
