The T script and management studio are seen in the following figure. Next we'll use a Transact-SQL query to collect the server name, database name and file information.

How to write a mysql script

Sometimes it is needed to run some MySQL queries from the Linux command-line interface without accessing the interactive MySQL prompt. For example, when it is required to schedule a backup of MySQL database or to automate execution of some SQL queries with a Bash script. --help. Display a help message and exit. --basedir=dir_name The path to the MySQL installation directory. --core-file-size=size The size of the core file that mysqld should be able to create. The option value is passed to ulimit -c. This is an example script showing how to output a product table from a Mysql database. Note: the table must fit in a single page. For a more advanced script, see Table with MySQL.

Introduction A growing number of applications today use data represented in the form of XML documents. As a result, many standardized XML processing tools has been written.

What is the impact of these developments for users of the MySQL database system? Many of the most popular languages for writing MySQL applications also have XML support, so these languages provide a natural bridge for spanning the gap between XML and relational databases.

The following list indicates just some of the possibilities open to you for employing XML processing techniques to make more productive use of your MySQL server: XML as a data transfer medium. Writing a query result as an XML document results in a platform-neutral ASCII file that can be used by other applications, even those that are not necessarily database-oriented.

The recipient of such a document can employ standard XML tools to parse it and recover the original data values. This works in the other direction, too.

XML as a web delivery format. For example, you can set up an information feed that clients can use on an automated basis: Define XML formatting conventions with which to express the information and provide access to it through a web script.

Clients can send requests to the script, which connects to MySQL, retrieves the desired information, and formats it as an XML document that is returned to the client. The client then extracts information from the document using standard XML tools. Using XML to write web pages. As the limitations of HTML for writing web pages become more keenly felt, web developers turn increasingly to the greater expressive capabilities of XML.

For example, an XML document can incorporate the results of database queries and then, with the help of a rendering engine such as AxKit, be transformed into a format that matches the type of client you wish to serve. Or, as indicated in the previous item, you can serve the document directly to clients that understand XML.

Contrast this with HTML, which does not render well into other formats. You can of course store XML itself in your database. You might store templates for documents such as form letters that you combine with customer records to produce mailings, for example.

To help you get started, this article focuses on the tasks described in the data transfer and web delivery items in the preceding list. It shows how to create XML documents from query results, how to create new database records from information contained in XML documents, and how to set up a web-based XML delivery service.

You can use XML from within any language that has the appropriate processing tools available. MySQL can be obtained at www. The examples shown here assume that you have a MySQL database named test on the local host, accessed through a MySQL account with a user name and password of testuser and testpass.

Suppose that you want to produce XML output from a table named animal that has two string columns: The two methods shown in the following discussion demonstrate how to write an XML document "manually" by adding the XML tags yourself, or by using one of the available Perl modules to do most of the work.

Connect to MySQL, issue the query, fetch the results, and wrap them within the appropriate tags required to produce a properly formatted XML document: However, it also has some specific disadvantages: Knowledge of the table structure is built in, such as the column names to use for element tags within the rows.

This means the code could not be used for a different query without modifying the processing loop. The animal table does not have any, but another table might, in which case any output generated from it would be malformed. The script could be rewritten to be less query-specific and to perform encoding, but an easier approach is to use existing Perl modules that do the work for you.

This module is designed to work in concert with DBI, which makes it especially convenient for writing scripts that fetch information from MySQL or other databases.

DBI consists of two methods: Pass the database handle and the SAX object to new to obtain an object to use for executing queries. The following script shows how to use XML:: YAWriter yet another writer module. For example, to generate XML for a different query, all you have to do is change the argument to the execute call.The MySQL server maintains many system variables that configure its operation.

Each system variable has a default value. System variables can be set at server startup using options on the command line or in an option file.
