将日期传递给MySQL查询时的VBA运行时错误:VBA run-time error when passing dates to MySQL query

将日期传递给MySQL查询时的VBA运行时错误的处理方法

我从Excel VBA连接到MySQL以获取my_stored_procedure.正常运行,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.

用户在两个单元格中输入日期过滤器作为开始日期和结束日期.单元格定义为dateFrom和dateTo范围.

所以我正在使用这些范围来传递给mySql rs,但是VBA会返回:

运行时错误'-2147217900(80040e14)'

您的MySQL语法有误;检查相应的手册到您的MYSQL服务器版本...'my_stored_procedure'2015-10-01',第1行的"2015-10-30".

下面是我的VBA代码:

  Const ConnStr As String ="Driver = {MySQL ODBC 5.3 ANSI Driver};服务器= 0.0.0.0;数据库= db;用户=用户;密码= pw;选项= 3;端口= 3306;连接超时= 20;函数MySqlCommand(strSql As String)As Variant昏暗的conMySQL设置conMySQL = CreateObject("ADODB.Connection")设置cmd = CreateObject("ADODB.Command")conMySQL.ConnectionString = ConnStrconMySQL.Open设置cmd.ActiveConnection = conMySQLcmd.CommandText = strSqlReturnValue = cmd.ExecuteconMySQL.关闭结束功能函数MySqlRS(strSql作为字符串)作为ADODB.Recordset昏暗的conMySQL设置conMySQL = CreateObject("ADODB.Connection")设置rs = CreateObject("ADODB.Recordset")conMySQL.ConnectionString = ConnStrconMySQL.Open设置rs.ActiveConnection = conMySQLrs.Open strSql设置MySqlRS = rs结束功能_____公共子fetchReport()作为ADODB.Recordset的昏暗设置rs = MySqlRS("my_stored_procedure'"& Format(Range("dateFrom"),"yyyy-mm-dd")&','"& Format(Range("dateTo"),"yyyy-mm-dd)&"')昏暗的高清整数如果不是rs.EOF,则对于hd = 0到rs.Fields.Count-1Worksheets("data").Cells(1,hd + 1).Value = rs.Fields(hd).Name'插入列标题下一个Sheets("data").Range("A2").CopyFromRecordset rs'插入数据Sheets("data").Range("A1").CurrentRegion.Name ="rsRange"'设置数据透视表的命名范围万一ActiveWorkbook.RefreshAll结束子 

这是我的SP语法:

  CREATE DEFINER =`user` @`%`程序my_stored_procedure`(在fromDate日期,截止日期)开始选择 ...dateColumn> = fromDate和dateColumn< = toDate结尾 

感谢您的帮助.

解决方案

我希望这会有所帮助.自从我这样做已经很长时间了.

架构

 创建表myTable(id int auto_increment主键,dateColumn日期不为null,资料varchar(100)不为null);插入myTable(dateColumn,stuff)值('2014-12-21','dogs'),('2015-02-21','frogs'),('2015-07-21','snakes'),('2015-12-21','猫'); 

存储过程

 删除过程(如果存在)"my_stored_procedure";分隔符$$创建过程`my_stored_procedure`(在fromDate日期,截止日期)开始选择 *从myTable其中dateColumn> = fromDate和dateColumn< = toDate;结尾$$定界符;

我想探索对新函数 MySqlStoredProcRS 的更改,使用 call 的ADODB.RecordSet的处理以及将参数包装在调用字符串中的括号./p>

祝你好运.

From Excel VBA i connect to MySQL to fetch my_stored_procedure. Working fine except that when I use date filter as parameters to pass to MySQL SP i receive a run-time error.

The date filters are entered by the user in two cells as start-date and end-date. The cells are defined defined as ranges dateFrom and dateTo.

So I'm using these ranges to pass on to mySql rs, but VBA throws back:

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.

Below is my VBA code:

        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

And here is my SP syntax:

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

Any help is appreciated.

解决方案

I hope this is helpful. Been a long time since I have done this.

Schema

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');

Stored Proc

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

The Takeaway

I guess explore the changes to the new function MySqlStoredProcRS, the handling of the ADODB.RecordSet, using call, and parentheses wrapping the parameters in the call string.

Good luck.
