[英]How to use access pass-through query in a form
I'm using pass-through query code below on access. 我在访问时使用下面的传递查询代码。 The code isn't a problem.
代码不是问题。 My problem is to make a form on access that enters the varible on the place indicated and returns me the table from que SQL select.
我的问题是要在访问时形成一个表格,在指定的位置输入变量,然后从que SQL select中返回表。 The regular solution: [Form]![Variable] doesn't work, because pass-through query doesn't support it I imagine (I'm not an Access expert).
常规解决方案:[Form]![Variable]不起作用,因为我想直通查询不支持它(我不是Access专家)。 Does anyone have a solution for this problem?
有人对此问题有解决方案吗?
SELECT instalacao
,tipounidade
FROM sgdprd.useccionadora us
INNER JOIN (
SELECT bloco
FROM sgdprd.redeprimaria rp
WHERE rp.useccionadora IS NOT NULL CONNECT BY rp.nox = PRIOR rp.fontex
AND rp.noy = PRIOR rp.fontey START
WITH rp.utransformadora = (
SELECT utransformadora
FROM sgdprd.redeprimaria rp
INNER JOIN sgdprd.consumidor con ON rp.utransformadora = con.instalacao
WHERE con.conta = '**VARIABLE GOES HERE**'
)
) lista ON lista.bloco = us.instalacao
WHERE us.tipounidade = 'DJ'
OR us.tipounidade = 'RL'
You don't mention what you want to do with the results of this query? 您没有提及要对该查询的结果做什么?
Any pass-through query is read only. 任何传递查询都是只读的。
However, you can use the following code: 但是,您可以使用以下代码:
Dim strSQL As String
strSQL = "your sql goes here where con.contra='[P1]' bla bla"
strSQL = Replace(strSQL, "[P1]", Me.SomeControl)
With CurrentDb.QueryDefs("QryPass")
.SQL = strSQL
End With
It is assumed that me.SomeControl in the form is say restricted to a number column since if it is a free form text box, then you are open to sql injection. 假定表单中的me.SomeControl被限制为一个数字列,因为如果它是自由格式的文本框,则您可以进行sql注入。 QryPass is simply a saved pass-though query and you can re-use that query over and over in code for any T-sql or server side commands you wish.
QryPass只是一个保存的传递查询,您可以在代码中一遍又一遍地重复使用该查询,以获取所需的任何T-sql或服务器端命令。
As noted, you have to share additional information as to what you want to do with the pass-through query (such as assign to a recordset, combo box, report or even perhaps the forms recordsource - so addtitional info is needed to complete this problem, but the above provides a working example. 如前所述,您必须共享有关传递查询要执行的操作的其他信息(例如,分配给记录集,组合框,报表甚至表单记录源),因此需要其他信息才能解决此问题,但以上提供了一个有效的示例。
