.net2.0 connection Mysql5 database configuration
I have always preferred Mysql. The main reasons are: 1. The database is small in size. 2. The database is open source and free. 3. The database has many useful client tools.
4. Cross-platform. 5. The performance and functions are relatively powerful (it is impossible to compare with those heavyweights). 6. Easy to transplant, deploy and install. Therefore, Mysql is generally the first choice for small projects I do. Recently, I am using the combination of .net sqlserver05, but I am suffering from the sqlserver enterprise version. The standard version only supports server 03. My computer is XP,
, so I am very depressed. I installed Express, which has too few functions. . It's not fun to use either. Can't even remove it cleanly. Finally, I even considered using someone else's Sqlserver2000 Enterprise
version remotely. But because .net also supports Mysql connection, I searched online for implementation and required tools. There is really no technical content. It seems that I can also consider the combination of
.net Mysql in the future. There is a lot of information on this aspect on the Internet, and I will only record my own implementation experience. If you don’t know it, please refer to it. If you know it, just take a detour.
Download tool:
Mysql connector/net5.0 download address:
http://dev.mysql.com/get/Downloads/Connector-Net/mysql-connector- net-5.0.6.zip/from/pickJust install it directly after downloading.
After the installation is complete, add a reference to the project and you can use it.
Let’s show the code below: The function is to read a user table from Mysql and execute the Mysql stored procedure. The example is not difficult, success is the answer. The execution of
on this machine has passed. Native environment: XP Mysql5 VS05 C# (ASP.NET2.0)
The code is very simple, mainly for testing:
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
using MySql.Data.MySqlClient;
namespace ConnectMysql
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack){
MySqlConnection con = DB.createCon();
string sql = "select * from t_user";
MySqlDataAdapter mda = new MySqlDataAdapter(sql,con);
DataSet ds = new DataSet();
mda.Fill(ds, "user");
this.GridView1.DataSource = ds;
this.GridView1.DataBind();
}
}
protected void Button1_Click(object sender, EventArgs e)
{
MySqlConnection con = DB.createCon();
MySqlCommand cmd = new MySqlCommand("getUsername", con);
cmd.CommandType = CommandType.StoredProcedure;
con.Open();
try
{
MySqlDataReader dr = cmd.ExecuteReader();
this.GridView2.DataSource = dr;
this.GridView2.DataBind();
con.Close();
}
catch(Exception ex)
{
ex.ToString();
con.Close();
}
}
}
}The question is quite attractive, in fact.net1.0 even Mysql is actually the same.

When might a full table scan be faster than using an index in MySQL?
Apr 09, 2025 am 12:05 AM
Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.
Can I install mysql on Windows 7
Apr 08, 2025 pm 03:21 PM
Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it.

Explain InnoDB Full-Text Search capabilities.
Apr 02, 2025 pm 06:09 PM
InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.
Difference between clustered index and non-clustered index (secondary index) in InnoDB.
Apr 02, 2025 pm 06:25 PM
The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.
MySQL: Simple Concepts for Easy Learning
Apr 10, 2025 am 09:29 AM
MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.
Can mysql and mariadb coexist
Apr 08, 2025 pm 02:27 PM
MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
The relationship between mysql user and database
Apr 08, 2025 pm 07:15 PM
In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.
Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial).
Apr 02, 2025 pm 07:05 PM
MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
