查询数据表时出错 [英] error querying the datatable
问题描述
我的数据表只包含一个字段cl_mt,另一个数据表包含3个字段cl_id,cl_description,cl_mt我正在尝试编写以下代码:
i have a datatable that contains only a single field "cl_mt" and another datatable that contains 3 fields "cl_id","cl_description","cl_mt" i'm trying to write the following code:
Dim dt() As DataRow
dt = serviceTable.Select("cl_id,cl_description where cl_mt='" & CInt(mt_combo.SelectedValue) & "'")(0).Item("cl_cl_id")
i需要从我的数据表中获取所有cl_id和cl_description cl_mt等于另一个数据表中的某个值
我写的代码给我索引错误和语法错误
< b r />
请注意两个数据表都被填充组合框
任何想法如何改进我的查询?
i need to get all the cl_id and the cl_description from my datatable where the cl_mt is equal to a certain value in the other datatable
the code i'm writing is giving me index error and syntax error
note that both datatables are being filled a comboboxes
any idea how can i improve my query?
