Create a database table and save data in the PHPMySQL Getting Started Tutorial. In mysql, if we want to use PHP to create a database and a table, we can directly use mysql_query () to execute the mysql table creation command, CREATEDATABASEdatabase_name.

This article describes how to connect C # To the database through web. config configuration and call methods.
Connect to access, SQL Server, and Oracle databases through vs2005.
Next we will introduce C # connecting to the database:
First, create a new project and add a class for database connection.
Here we name this class database. cs. below is the content of this class.

background color of the view is nil or if the color is a little bit transparent, Then the rectangular area of the cgcontextclearrect will appear transparent, and the punched hole will pass through the view including its background color. If the background color is completely opaque, then the result of the cgcontextclearrect function will be black. This is because the background color of the view determines whether the graphics context of the view is transparent or opaque.Figure 5 Application of
In mysql, if we want to use PHP to CREATE databases and tables, we can directly use mysql_query () to execute the mysql table creation command, create database database_name.
The details are as follows:
To allow PHP to execute the preceding statement, we must use the mysql_query () function. This function is used to send queries or commands to MySQL connections.
Example
In the following example, we created a database named "my_db:

Today, I saw a post in the php forum asking my friend how to convert a string into an array. As a new php programmer, the first response is to think of explode (), implode () these two functions. The new one is also converted to an array using the functions in it. Con [1] 28 selt [1] 1con [2] 29 selt [2] 4con [3] 26 selt [3] 4con [4] 30 s
