Question

我正在使用C＃和Asp.Net。我有以下数据适配器和数据集：

SqlDataAdapter da_Select_Matching_Records;
DataSet ds_for_showing_X_Rows_Cols = new DataSet();

我想用查询结果填写数据集ds_for_showing_X_Rows_Cols。这是我的代码：

    con = new SqlConnection("Data Source=local;Initial Catalog=Test;Integrated Security=True");

da_Select_Matching_Records = new SqlDataAdapter("Select BusinessSector5.Description_DE, SubCategory.Kategorie "+
"FROM   Match_Subcategory_BusinessSector5 INNER JOIN "+
" SubCategory ON Match_Subcategory_BusinessSector5.SubCategoryID = SubCategory.ID INNER JOIN "+
" BusinessSector5 ON Match_Subcategory_BusinessSector5.BusinessSector5ID = BusinessSector5.ID", con);

//Filling of Data Set
da_Select_Matching_Records.Fill(ds_for_showing_X_Rows_Cols, "Description_DE, Kategorie");

我收到此错误，在我填充数据集的行上。我在Sql Server管理工作室中使用了查询并且运行正常。

Incorrect syntax near the keyword INNER.

Answer 1

您需要在此行的末尾添加空格：

"FROM   Match_Subcategory_BusinessSector5 INNER JOIN"+

即

"FROM   Match_Subcategory_BusinessSector5 INNER JOIN "+

这条线也一样：

"SubCategory ON Match_Subcategory_BusinessSector5.SubCategoryID = SubCategory.ID  INNERJOIN"+

INNER和JOIN之间也没有空格。

因此，要确认，请为所有行添加尾随空格，并在内部和连接之间添加空格

使用数据适配器查询结果C＃Asp.Net填充数据集
