在vb.net datagrid視圖中選擇多個表sql-sql＆vb.net

Question

我試圖在mysql中選擇多個表，然后將其返回到我的應用程序的datagridview中。 SQL查詢失敗，無法正常工作。 sql錯誤嗎？ 我在MySQL中有兩個表叫做“ bruker ”和“ blodgiver ”

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

您必須提供on子句。

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