在vb.net datagrid视图中选择多个表sql --sql＆amp; vb.net

Question

我正在尝试在mysql中选择多个表，然后将其返回到我的应用程序的datagridview。下面的SQL查询不起作用。 sql是错的吗？我有两个名为＆＃34; bruker＆＃34; ＆安培; ＆＃34; blodgiver＆＃34;在mysql中

Dim searchQuery As String = "SELECT bruker INNER JOIN blodgiver WHERE CONCAT(bruker_id, fornavn, etternavn, epost, personnummer) like '%" & valueToSeach & "%'"

Dim command As New MySqlCommand(searchQuery, MysqlConn)
Dim adapter As New MySqlDataAdapter(command)
Dim table As New DataTable()

adapter.Fill(table)

DataGridView1.DataSource = table

Answer 1

你必须提供on条款。

SELECT * FROM bruker br INNER JOIN blodgiverbd on bd.<link_column1> = db.<link_column2>  WHERE CONCAT(bruker_id, fornavn, etternavn, epost, personnummer) like '%" & valueToSeach & "%'"
