Basic CUCM SQL Queries-1

Lets learn some basics of SQl Queries and try it on CUCM.

What SQL?

SQL is used to communicate with a database. According to ANSI (American National Standards Institute), it is the standard language for relational database management systems. SQL statements are used to perform tasks such as update data on a database, or retrieve data from a database. Some common relational database management systems that use SQL are: Oracle, Sybase, Microsoft SQL Server, Access, Ingres, etc. Although most database systems use SQL, most of them also have their own additional proprietary extensions that are usually only used on their system. However, the standard SQL commands such as “Select”, “Insert”, “Update”, “Delete”, “Create”, and “Drop” can be used to accomplish almost everything that one needs to do with a database.

Selecting Data

The select statement is used to query the database and retrieve selected data that match the criteria that you specify. Here is the format of a simple select statement:     select “column1″  [,”column2”,etc]   from “tablename” 

The column names that follow the select keyword determine which columns will be returned in the results. You can select as many column names that you’d like, or you can use a “*” to select all columns.

The table name that follows the keyword from specifies the table that will be queried to retrieve the desired results.
