1】下載安裝好mySQL環境

2】FDConnection1的設置

3】執行增刪改SQL語句和查詢Select語句

4】客戶端鏈接

1】下載安裝好mySQL環境，注意32位/64位。本篇爲32位

用戶命令行,修改密碼 。增長DataBase，db1

---

cd c:\mysql-5.7\bin
mysqld --install
mysqld --initialize --console//有默認密碼，記得保存
net start mysql

mysql -u root -p //輸入密碼
     alter user 'root'@'localhost' identified by 'root';

     create database db1;

use db1;

 show tables;

create table tb1 (id int);

insert into tb1 values (2);

Path路徑系統變量加入c:\mysql-5.7\bin

---

 將libmysql.dll拷到C:\Windows\System32

 確保MySQL服務啓動，也能夠命令行啓動MySQL服務            net start mysql

---

 2】FDConnection1的設置

 FDConnection1.LoginPrompt: = False;//不提示登陸窗口。

---

 3】執行,增insert，改update ，刪除delete 語句SQL語句

procedure TForm3.Button1Click(Sender: TObject);
begin
 FDConnection1.ExecSQL('insert into tb1 values(5);');
  button1.Caption := FDConnection1.ExecSQLScalar('select MAX(id) from tb1');
end;

    3-2】執行select 查詢語句，要新加FDQuery1，設置FDQuery1的Connection爲FDConnection1

FDQuery1.Open('select * from tb1 where id>5');

---

4】客戶端鏈接

http://www.javashuo.com/article/p-mboezxyd-by.html

1、SQLConnection1: TSQLConnection
ConnectionName = 'MYSQLCONNECTION'
DriverName = 'MySQL'
GetDriverFunc = 'getSQLDriverMYSQL'
LibraryName = 'dbxmys.dll'
LoginPrompt = False
Params.Strings = (
'HostName=localhost'
'Database=mysqldb'
'User_Name=root'
'Password=pswd'
'MaxBlobSize=-1

ServerCharSet=utf8')
VendorLib = 'libmysql.dll'
Connected = True

2、 SQLTable1: TSQLTable
GetMetadata = False
MaxBlobSize = -1
SQLConnection = SQLConnection1
TableName = 'human'


3、DataSource1: TDataSource
DataSet = ClientDataSet1

4、DataSetProvider1: TDataSetProvider
DataSet = SQLTable1

5、ClientDataSet1: TClientDataSet
Active = True
ProviderName = 'DataSetProvider1'


6、DBGrid1: TDBGrid
DataSource = DataSource1

7、 DBNavigator1: TDBNavigator
 DataSource = DataSource1
 

8、Button1: TButton
Caption = 'Button1'
OnClick = Button1Click

須要的控件

procedure TForm1.Button1Click(Sender: TObject);
begin
  ClientDataSet1.ApplyUpdates(0);//更新
end;

最後找到兩個庫文件一同發佈就能夠了。

LibraryName = 'dbxmys.dll'VendorLib = 'libmysql.dll'
