mysql - 将日期传递给 MySQL 查询时出现 VBA 运行时错误

Question

我从 Excel VBA 连接到 MySQL 以获取 my_stored_procedure。工作正常，除了当我使用日期过滤器作为参数传递给 MySQL SP 时，我收到运行时错误。

日期过滤器由用户在两个单元格中输入，即开始日期和结束日期。单元格被定义为范围 dateFrom 和 dateTo。

所以我使用这些范围传递给 mySql rs，但 VBA 会返回:

Run-time error '-2147217900 (80040e14)'

You have an error in MySQL syntax; check the manual that corresponds to your MYSQL server version... 'my_stored_procedure '2015-10-01', '2015-10-30'' at line 1.

下面是我的 VBA 代码:

        Const ConnStr As String = "Driver={MySQL ODBC 5.3 ANSI Driver};Server=0.0.0.0;Database=db;User=user;Password=pw;Option=3;PORT=3306;Connect Timeout=20;"

Function MySqlCommand(strSql As String) As Variant
    Dim conMySQL
    Set conMySQL = CreateObject("ADODB.Connection")
    Set cmd = CreateObject("ADODB.Command")
    conMySQL.ConnectionString = ConnStr
    conMySQL.Open
    Set cmd.ActiveConnection = conMySQL
    cmd.CommandText = strSql
    ReturnValue = cmd.Execute
    conMySQL.Close
End Function

Function MySqlRS(strSql As String) As ADODB.Recordset
    Dim conMySQL
    Set conMySQL = CreateObject("ADODB.Connection")
    Set rs = CreateObject("ADODB.Recordset")
    conMySQL.ConnectionString = ConnStr
    conMySQL.Open
    Set rs.ActiveConnection = conMySQL
    rs.Open strSql
    Set MySqlRS = rs
End Function
_____
Public Sub fetchReport()

Dim rs As ADODB.Recordset
    Set rs = MySqlRS("my_stored_procedure '" & Format(Range("dateFrom"), "yyyy-mm-dd") & "' ,'" & Format(Range("dateTo"), "yyyy-mm-dd") & "' ")
Dim hd As Integer


    If Not rs.EOF Then
            For hd = 0 To rs.Fields.Count - 1
                Worksheets("data").Cells(1, hd + 1).Value = rs.Fields(hd).Name  'insert column headers
            Next

        Sheets("data").Range("A2").CopyFromRecordset rs  'insert data
        Sheets("data").Range("A1").CurrentRegion.Name = "rsRange"  'set named range for pivot
    End If

ActiveWorkbook.RefreshAll

End Sub

这是我的 SP 语法:

CREATE DEFINER=`user`@`%` PROCEDURE `my_stored_procedure`
(
in fromDate date,
in toDate date
)
BEGIN
SELECT ...
WHERE dateColumn >= fromDate AND dateColumn <= toDate 
END

感谢任何帮助。

我希望这对您有所帮助。自从我这样做以来已经很长时间了。

架构

create table myTable
(   id int auto_increment primary key,
    dateColumn date not null,
    stuff varchar(100) not null
);
insert myTable(dateColumn,stuff) values
('2014-12-21','dogs'),('2015-02-21','frogs'),('2015-07-21','snakes'),('2015-12-21','cats');

存储过程

drop procedure if exists `my_stored_procedure`;
DELIMITER $$
CREATE PROCEDURE `my_stored_procedure`
(
    in fromDate date,
    in toDate date
)
BEGIN
    SELECT * 
    from myTable
    WHERE dateColumn >= fromDate AND dateColumn <= toDate; 
END
$$
DELIMITER ;

VBA

Function MySqlStoredProcRS(strSql As String) As ADODB.Recordset
    Dim conMySQL
    Set conMySQL = CreateObject("ADODB.Connection")
    Set rs = CreateObject("ADODB.Recordset")
    conMySQL.ConnectionString = ConnStr ' not shown but like yours in Op Question
    conMySQL.Open
    Set rs.ActiveConnection = conMySQL
    rs.CursorLocation = adUseClient
    rs.Open strSql, conMySQL, , , adCmdText
    Set MySqlStoredProcRS = rs
End Function
Public Sub fetchReport()

Dim rs As ADODB.Recordset
Dim sql As String
sql = "call my_stored_procedure ('" & Format(Range("dateFrom"), "yyyy-mm-dd") & "' ,'" & Format(Range("dateTo"), "yyyy-mm-dd") & "')"
Set rs = MySqlStoredProcRS(sql)
Dim hd As Integer


    If Not rs.EOF Then
            For hd = 0 To rs.Fields.Count - 1
                Worksheets("data").Cells(1, hd + 1).Value = rs.Fields(hd).Name  'insert column headers
            Next

        Sheets("data").Range("A2").CopyFromRecordset rs  'insert data
        Sheets("data").Range("A1").CurrentRegion.Name = "rsRange"  'set named range for pivot
    End If

ActiveWorkbook.RefreshAll

End Sub

要点

我想探索一下新函数 MySqlStoredProcRS 的更改、ADODB.RecordSet 的处理、使用 call 以及将参数括在调用字符串中的括号。

祝你好运。
