C# SqlSugar框架的学习使用（四）-- 插入数据的详细用法

前言web

上一篇《C# SqlSugar框架的学习使用（三）-- 查询的多种用法》咱们已经把SqlSugar的查询多种用法实现了，这篇咱们就来讲说插入数据的多种用法。数据库

数据表 POSTemp框架

咱们仍是用前面介绍的数据库，由于此次插入时要讲一下存在自增加类型的数据，因此咱们如今用POSTemp这个表，结构以下图：ide

程序中加入插入的功能按钮等，以下图：性能

POSTemp类学习

using System;using System.Linq;using System.Text;using SqlSugar;
namespace Model{ ///<summary> /// ///</summary> public partial class POSTemp { public POSTemp() {

 } /// <summary> ///  /// </summary> [SugarColumn(IsPrimaryKey = true, IsIdentity = true)] public int sn { get; set; }
 /// <summary> /// Desc: /// Default: /// Nullable:False /// </summary> public string Posno { get; set; }
 /// <summary> /// Desc: /// Default: /// Nullable:False /// </summary>  public string Posname { get; set; }
 /// <summary> /// Desc: /// Default: /// Nullable:True /// </summary>  public string OrgCode { get; set; }
 /// <summary> /// Desc: /// Default: /// Nullable:True /// </summary>  public string status { get; set; }
 }}

代码演示

插入返回影响行数ui

 private void tsmnuinsertcount_Click(object sender, EventArgs e) { try { POSTemp pos = new POSTemp(); pos.Posno = "0001"; pos.Posname = "01款台"; pos.OrgCode = "001"; pos.status = "1";
 int count = _db.Insertable(pos).ExecuteCommand(); TextShow("插入了" + count + "条数据"); } catch (Exception ex) { TextShow(ex.Message); } }

插入返回自增列
url

 private void tsmnuinsertident_Click(object sender, EventArgs e) { try { POSTemp pos = new POSTemp(); pos.Posno = "0002"; pos.Posname = "02款台"; pos.OrgCode = "001"; pos.status = "1";
 int count = _db.Insertable(pos).ExecuteReturnIdentity();  TextShow("插入数据成功，自增列序号为：" + count ); } catch (Exception ex) { TextShow(ex.Message); } }

插入返回实体

 private void tsmnuinsertcls_Click(object sender, EventArgs e) { try { POSTemp pos = new POSTemp(); pos.Posno = "0003"; pos.Posname = "03款台"; pos.OrgCode = "001"; pos.status = "1";
 POSTemp retPosTemp = _db.Insertable(pos).ExecuteReturnEntity(); TextShow("插入数据成功"); TextShow("sn:" + retPosTemp.sn + " Posno:" + retPosTemp.Posno + " PosName:" + retPosTemp.Posname); TextShow("OrgCode:" + retPosTemp.OrgCode + " status:" + retPosTemp.status); } catch (Exception ex) { TextShow(ex.Message); } }

只插入对应列

 private void tsmnuinsertcolumn_Click(object sender, EventArgs e) { try { POSTemp pos = new POSTemp(); pos.Posno = "0004"; pos.Posname = "04款台"; pos.OrgCode = "001"; pos.status = "1";
 int count = _db.Insertable(pos) .InsertColumns(t => new {t.Posno, t.Posname}) .ExecuteReturnIdentity(); TextShow("只插对应列数据成功，自增列序号为：" + count); } catch (Exception ex) { TextShow(ex.Message); } }

不插入对应列

 private void tsmnuinsertignore_Click(object sender, EventArgs e) { try { POSTemp pos = new POSTemp(); pos.Posno = "0005"; pos.Posname = "05款台"; pos.OrgCode = "001"; pos.status = "1";
 int count = _db.Insertable(pos) .IgnoreColumns(t => new { t.OrgCode }) .ExecuteReturnIdentity(); TextShow("不插对应列数据成功，自增列序号为：" + count); } catch (Exception ex) { TextShow(ex.Message); } }

根据条件指定不插入列

 private void tsmnuinsertignorewhere_Click(object sender, EventArgs e) { try { POSTemp pos = new POSTemp(); pos.Posno = "0006"; pos.Posname = "06款台"; pos.OrgCode = "001"; pos.status = "1";
 int count = _db.Insertable(pos) .IgnoreColumns(t => t == "status") .ExecuteReturnIdentity(); TextShow("根据条件不插对应列数据成功，自增列序号为：" + count); } catch (Exception ex) { TextShow(ex.Message); } }

List中全部列不插入

 private void tsmnuinsertignorelist_Click(object sender, EventArgs e){ try { POSTemp pos = new POSTemp(); pos.Posno = "0007"; pos.Posname = "07款台"; pos.OrgCode = "001"; pos.status = "1";
 List<string> list= new List<string>(); list.Add("OrgCode"); list.Add("status");
 int count = _db.Insertable(pos) .IgnoreColumns(t => list.Contains(t)) .ExecuteReturnIdentity(); TextShow("根据条件不插对应列数据成功，自增列序号为：" + count); } catch (Exception ex) { TextShow(ex.Message); } }

插入使用锁

 private void tsmnuinsertlock_Click(object sender, EventArgs e) { try { POSTemp pos = new POSTemp(); pos.Posno = "0008"; pos.Posname = "08款台"; pos.OrgCode = "001"; pos.status = "1";
 int count = _db.Insertable(pos) .With(SqlWith.UpdLock) .ExecuteReturnIdentity(); TextShow("插入使用锁数据成功，自增列序号为：" + count); } catch (Exception ex) { TextShow(ex.Message); } }

批量插入（性能很快不用操心）

 private void tsmnuinsertarray_Click(object sender, EventArgs e) { try { List<POSTemp> listpos = new List<POSTemp>(); for (int i = 0; i < 3; i++) { POSTemp pos = new POSTemp(); pos.Posno = "001"+i; pos.Posname = pos.Posno + "款台"; pos.OrgCode = "001"; pos.status = "1"; listpos.Add(pos); }
 int count = _db.Insertable(listpos.ToArray()) .ExecuteCommand(); TextShow("List插入数据，成功插入" + count + "条数据"); } catch (Exception ex) { TextShow(ex.Message); } }

匿名对象和字典的支持

 private void tsmnuinsertdictionary_Click(object sender, EventArgs e) { try { int count = _db.Insertable<POSTemp>( new { Posno = "0013", Posname = "13款台" }) .ExecuteReturnIdentity(); TextShow("匿名对插成功插入成功，自增序号为：" + count);
 count = _db.Insertable<POSTemp>( new Dictionary<string, object>() { { "Posno","0014"}, {"Posname","14款台" } }) .ExecuteReturnIdentity(); TextShow("字典方式插成功插入成功，自增序号为：" + count); } catch (Exception ex) { TextShow(ex.Message); } }

将A表数据插入B表

咱们将POSTemp的表数据插入到POS中，先看下图，POSTemp中有13条数据，POS中没有数据

插入代码

 private void tsmnuinsertAtoB_Click(object sender, EventArgs e) { try { int count = _db.Insertable(_db.Queryable<POSTemp>() .Select<POS>().ToList()).ExecuteCommand(); TextShow("从POSTemp表中向POS表中成功插入了" + count + "条数据"); } catch (Exception ex) { TextShow(ex.Message); } }
