# xyDb

Definition of general database operation interface and implementation of specific database operations for each database  

  

Currently includes: SQLite64, PostgreSQL, SqlServer, MySql    

## Sample

Please read code details in project xyDbSample.  

### Create DbService

IDbAccess dbAccess = new SQLite64DbAccess();  

//IDbAccess dbAccess = new PostgreSQLDbAccess();  

//IDbAccess dbAccess = new SQLServerDbAccess();  

string ConnectionString = @"Data Source=testDb;";  

//string ConnectionString = @"Server=localhost;Database=testdb;User Id=testuser;Password=testPassword;";  

//string ConnectionString = @"Server=localhost\\SQLEXPRESS;uid=testUser;pwd=testPassword;database=testDb;Packet Size=8192;Max Pool Size=1000;Connect Timeout=30;";  

DbService = new DbService(ConnectionString, dbAccess);  

await DbService.openAsync();  

### New record and query

maxId++;  

string sql = "INSERT INTO COMPANY(ID, NAME, AGE) " + "VALUES(" + maxId + ", '', 0)";  

await dbService.exeSqlAsync(sql);  

sql = "SELECT * From COMPANY WHERE ID=" + maxId;  

DataTable dt = await dbService.exeSqlForDataSetAsync(sql);  

int i = dataGridView1.Rows.Add(dt.Rows[0].ItemArray);  

dataGridView1.Rows[i].Tag = dt.Rows[0];  

### Edit record

string colName = dataGridView1.Columns[e.ColumnIndex].Name;  

string cellValue = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();  

string rowID =  dataGridView1.Rows[e.RowIndex].Cells["ID"].Value.ToString();  

string sql = "UPDATE COMPANY SET " + colName + "='" + cellValue + "' "  + " WHERE ID=" + rowID;  

await dbService.exeSqlAsync(sql);  

### Delete record

int rowIndex = dataGridView1.SelectedRows[0].Index;  

int rowID = Convert.ToInt32(dataGridView1.Rows[rowIndex].Cells["ID"].Value);  

string sql = "DELETE FROM COMPANY " + " WHERE ID=" + rowID;  

await dbService.exeSqlAsync(sql);  

dataGridView1.Rows.RemoveAt(rowIndex);
