CUBRID学习笔记 37 ADO.NET Schema Provider

通常需要添加以下引用:

 

1 2 3

using System.Data; using System.Data.Common; using CUBRID.Data.CUBRIDClient;

定义连接字符串:

 

1 2	/* conection string, please modify before using. */ string _connString = "server=localhost;database=demodb;port=33000;user=public;password=";

用 CUBRIDConnectionStringBuilder生成连接字符串 这个我比较喜欢:

 

1 2 3 4 5 6 7 8

string server = "localhost"; int port = 33000; string database = "demodb"; string user = "public"; string password = ""; string encoding = "utf-8"; CUBRIDConnectionStringBuilder sb = new CUBRIDConnectionStringBuilder(server, port, database, user, password, encoding); string _connString = sb.GetConnectionString();

获取用户表:

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

/* create a new CUBRIDConnection instance */ using (CUBRIDConnection conn = new CUBRIDConnection()) {     try     {         /* set the connection string */         conn.ConnectionString = _connString;         /* connect to db server */         conn.Open();            /* create a new CUBRIDSchemaProvider instance */         CUBRIDSchemaProvider schema = new CUBRIDSchemaProvider(conn);         /* get all tables */         DataTable dt = schema.GetTables(new string[] { "%" });            /* print all tables */         for (int i = 0; i < dt.Rows.Count; i++)             Console.WriteLine(dt.Rowsi2.ToString());     }     catch (Exception exp)     {         Console.WriteLine(exp.Message);     } }

获取所有用户:

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

/* create a new CUBRIDConnection instance */ using (CUBRIDConnection conn = new CUBRIDConnection()) {     try     {         /* set the connection string */         conn.ConnectionString = _connString;         /* connect to db server */         conn.Open();           /* create a new CUBRIDSchemaProvider instance */         CUBRIDSchemaProvider schema = new CUBRIDSchemaProvider(conn);         /* get all users */         DataTable dt = schema.GetUsers(null);           /* print all users */         for (int i = 0; i < dt.Rows.Count; i++)             Console.WriteLine(dt.Rowsi0.ToString().ToUpper());     }     catch (Exception exp)     {         Console.WriteLine(exp.Message);     } }

获取所有视图: 

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

/* create a new CUBRIDConnection instance */ using (CUBRIDConnection conn = new CUBRIDConnection()) {     try     {         /* set the connection string */         conn.ConnectionString = _connString;         /* connect to db server */         conn.Open();           /* create a new CUBRIDSchemaProvider instance */         CUBRIDSchemaProvider schema = new CUBRIDSchemaProvider(conn);         /* get all tables */         DataTable dt = schema.GetViews(new string[] { "%" });           /* print all tables */         for (int i = 0; i < dt.Rows.Count; i++)             Console.WriteLine(dt.Rowsi2.ToString());     }     catch (Exception exp)     {         Console.WriteLine(exp.Message);     } }
