C＃插入数据到SQL表中

Question

我得到的sqlException是未处理的。 'nvarchar'附近的语法错误，'Name'附近语法不正确。我使用SMO来创建这样

Table TechOpsProjectTracker = new Table(db, "TechOpsProjectTracker"); 

//Add column ID 
DataType dt = new DataType(SqlDataType.Int); 
Column idColumn = new Column(TechOpsProjectTracker, "ID", dt); 
TechOpsProjectTracker.Columns.Add(idColumn); 

//Add Column Alignment 
DataType dt1 = new DataType(SqlDataType.NVarChar, 50); 
Column Column1 = new Column(TechOpsProjectTracker, "Alignment", dt1); 
TechOpsProjectTracker.Columns.Add(Column1); 

//Add Column Project Name 
DataType dt2 = new DataType(SqlDataType.NVarChar, 50); 
Column Column2 = new Column(TechOpsProjectTracker, "Project Name", dt2); 
TechOpsProjectTracker.Columns.Add(Column2); 

//Add Column Project Description 
DataType dt3 = new DataType(SqlDataType.NVarChar, 255); 
Column Column3 = new Column(TechOpsProjectTracker, "Project Description", dt3); 
TechOpsProjectTracker.Columns.Add(Column3); 

//Add Column Currently Assigned To 
DataType dt4 = new DataType(SqlDataType.NVarChar, 50); 
Column Column4 = new Column(TechOpsProjectTracker, "Currently Assigned To", dt4); 
TechOpsProjectTracker.Columns.Add(Column4); 
TechOpsProjectTracker.Create(); 

string connectionString = "Server=GSOPS4;Database=MyDatabaseName;Trusted_Connection=True;"; 

System.Data.SqlClient.SqlConnection sqlConnection1 = 
    new System.Data.SqlClient.SqlConnection(connectionString); 

System.Data.SqlClient.SqlCommand cmd = 
    new System.Data.SqlClient.SqlCommand(); 
cmd.CommandType = System.Data.CommandType.Text; 
cmd.CommandText = "INSERT TechOpsProjectTracker (ID, Alignment, Project Name, Project Description, Currently Assigned To) VALUES (@ID, @Alignment, @Project Name, @Project Description, @Currently Assigned To)"; 

SqlParameter ID = new SqlParameter("@ID", SqlDbType.Int); 
ID.Value = 5; 
cmd.Parameters.Add(ID); 

SqlParameter Alignment = new SqlParameter("@Alignment", SqlDbType.NVarChar, 50); 
Alignment.Value = "Right"; 
cmd.Parameters.Add(Alignment); 

SqlParameter ProjectName = new SqlParameter("@Project Name", SqlDbType.NVarChar, 50); 
ProjectName.Value = "Right Project Name"; 
cmd.Parameters.Add(ProjectName); 

SqlParameter ProjectDesc = new SqlParameter("@Project Description", SqlDbType.NVarChar, 255); 
ProjectDesc.Value = "Right Project Description"; 
cmd.Parameters.Add(ProjectDesc); 

SqlParameter Assignment = new SqlParameter("@Alignment", SqlDbType.NVarChar, 50); 
Assignment.Value = "corp\\shress2"; 
cmd.Parameters.Add(Assignment); 

cmd.Connection = sqlConnection1; 
sqlConnection1.Open(); 
cmd.ExecuteNonQuery(); 
sqlConnection1.Close(); 

我得到cmd.ExecuteNonQuery(); 任何原因，这些例外什么可能导致它的表？ TIA

有几个问题。

您的INSERT语句在列名中包含空格，因此您必须将它们括在括号中。
另外，参数名称中不能有空格，所以您需要将这些单词粘在一起。

cmd.CommandText = "INSERT TechOpsProjectTracker (ID, Alignment, [Project Name], [Project Description], [Currently Assigned To]) VALUES (@ID, @Alignment, @ProjectName, @ProjectDescription, @CurrentlyAssignedTo)"; 

然后，当你添加参数，同样的东西，粘在一起的话：

SqlParameter ProjectName = new SqlParameter("@ProjectName", SqlDbType.NVarChar, 50); 
ProjectName.Value = "Right Project Name"; 
cmd.Parameters.Add(ProjectName); 


SqlParameter ProjectDesc = new SqlParameter("@ProjectDescription", SqlDbType.NVarChar, 255); 
ProjectDesc.Value = "Right Project Description"; 
cmd.Parameters.Add(ProjectDesc);
