Apostrophe in sql string how can I remove - mysql

I need some help. I use a combo box to create a sql query. Here is the query string
SQlstr = "UPDATE maindata SET " _
& "?theoption1 = ?therec1 " _
& "WHERE acct = ?theaccount AND clientnumber=?theclient;"
?theoption1 is a field name but it comes out with an apostrophe like 'xxxxx' , and this causes an error. How do I get around this. I cant use Replace because I am using parameters.
Thanks for any help I can get.

strSQL formatting in Access

I am having some trouble formatting an SQL string in Access, I can never seem to debug these syntax issues with SQL strings. I have this string:
strSQL = "SELECT * FROM FXData WHERE ShortCode=" & Forms!FXVolatility.cboCurve.Value & " AND MaxOfMarkAsOfDate=#" & MaxOfMarkAsofDate & "# ORDER BY MaxOfMarkAsOfDate "
debug.print strSQL
Set rs = CurrentDb.OpenRecordset(strSQL, Type:=dbOpenDynaset, Options:=dbSeeChanges)
which prints
SELECT * FROM FXData WHERE ShortCode=USD.XS AND MaxOfMarkAsOfDate=#3/31/2016# ORDER BY MaxOfMarkAsOfDate
However this gives me a "Too Few Parameters, expected 1" error.
All the fields and their associated values that are referenced in strSQL exist in the referenced table. What could the error be?
Also if you've got any resources on how to debug/identify these specific access SQL formatting issues I'd be happy to hear them.
In SQL, strings need to be put in single or double quotes. Thus, your output should look like this:
... WHERE ShortCode='USD.XS' ...
Thus, your code becomes:
strSQL = "SELECT * FROM FXData WHERE ShortCode='" & _
Replace(Forms!FXVolatility.cboCurve.Value, "'", "''") & _
"' AND MaxOfMarkAsOfDate=#" & MaxOfMarkAsofDate & _
"# ORDER BY MaxOfMarkAsOfDate "
The Replace ensures that any single quotes occurring within cboCurve.Value are properly escaped.
Note that it is recommended to use parameters instead of string concatenation to "fill" values into an SQL statement. An example for how to do this in MS Access can be found in the answer to this question:
VBA OpenRecordset Producing Too few parameters. Expected 2. Error

Pass in Delimited String to Access Query as Parameter

I am trying to pass in a string to an Access query that has a parameter "companyType" . The sql is "where companyType in ([forms]![formname].[fieldname])"
This works fine with one value but for string e.g "CompanyType1","CompanyType2" it does not work.
I know the in operator needs to have each element in quotes if the data type for that field is a Short Text or Long text type. I have tried wrapping them in single quotes also to no avail.
When I hard code the values in the query e.g "in ('CompanyType1','CompanyType2')" query returns rows so I believe it is something with escaping the quotes but not exactly sure.
You won't be able to put this into an access query as a parameter; However you could build the query in vba:
dim qry as new QueryDef
qry.SQL = _
"SELECT some_column, ... " & _
"FROM some_table [INNER JOIN ...] " & _
"WHERE CompanyType IN (" & [list] & ")"
qry.Execute

Error 3061 Too few parameters 2 expected

I have been facing the error 3061 with error message "Too few Parameters: Expected 2". I have done all of the following to resolve the issue but still couldn't it.
I ran the query in SQL mode and it gives me result
I checked all the field names
I checked all the "&" s are placed. I find them correct.
Here is my code:
Private Sub cmbYear_Change()
Dim db As Database
Dim rs As DAO.Recordset
Dim Query As String
Query = " SELECT Yrs_Teaching, Highest_Edu, AD_Descr FROM ClassSurvey" & _
" WHERE ClassSurvey.Program/School_ID = " & Me.cmbProgId.Value & _
" AND ClassSurvey.ClassID = " & Me.cmbClassId.Value & _
" AND ClassSurvey.Teacher_ID = " & Me.cmbTeacherID.Value & _
" AND ClassSurvey.SYear = " & Me.cmbYear.Value
Set db = CurrentDb
Set rs = db.OpenRecordset(Query)
If rs.RecordCount > 0 Then
Me.TB1 = rs!Yrs_Teaching
Me.TB2 = rs!Highest_Edu
Me.TB3 = rs!AD_Descr
Else
Me.TB1 = "N/A"
End If
Set rs = Nothing
Set db = Nothing
End Sub
It appears your table includes a field named Program/School_ID. Bracket that field name in the SELECT statement so the db engine can properly recognize it as one field name.
That change might be all you need. But if you have another problem, give yourself an opportunity to examine the completed SELECT statement you're giving to the db engine. It might not be what you expect.
Dim db As Database
Dim rs As DAO.Recordset
Dim strQuery As String
strQuery = "SELECT cs.Yrs_Teaching, cs.Highest_Edu, cs.AD_Descr FROM ClassSurvey AS cs" & _
" WHERE cs.[Program/School_ID] = " & Me.cmbProgId.Value & _
" AND cs.ClassID = " & Me.cmbClassId.Value & _
" AND cs.Teacher_ID = " & Me.cmbTeacherID.Value & _
" AND cs.SYear = " & Me.cmbYear.Value
Debug.Print strQuery
Set db = CurrentDb
Set rs = db.OpenRecordset(strQuery)
If you get an error, you can go to the Immediate window (Ctrl+g), copy the statement text from there, open a new query in the query designer, switch to SQL View, paste in the statement text and try running it there. This tip is especially useful when the db engine complains about a missing parameter because when you try to run the query from the designer, Access will show you an input box asking you to supply a value and that box also contains the name of whatever Access thinks is the parameter.
I came across this when I was looking for a solution to the same problem. Turns out one of the values from a control on the form was not passing the value to the statement, sending it to the debug window (Debug.print) helped me spot the problem after a long time because I was using a global variable which the sql query was parsing. So load your controls' values into variables first!
This error may be because the column names in the query have special characters. Try surrounding the column names with square brackets in the SQL query. Column name with special symbols should be within square brackets and variables should be inside single quotes.
I had this issue too, I realized it was because I did not put quotes around my variables.
This was fixed by adding '& Chr(34)' around my variables
My fixed code looks like:
TextProducer = [Forms]![MyFormName]![TextInputBoxName]
strQuery = "SELECT FILEMASK" & _
" FROM TABLE_NAME" & _
" WHERE Producer = " & Chr(34) & TextProducer & Chr(34)

Combining 3 strings in Access VBA

I have a form that filters data by user, date range and specific value for a column, depending if checkbox is ticked or not, as below;
strWhere = " WHERE [user] in (" & Left(strIN, Len(strIN) - 1) & ") And [Month] Between [forms]![frm_user]![txtStartDate] And [forms]![frm_user]![txtEndDate]"
If Me!checkbox = True Then
strtcheck = " (Satified Vs Dissatisfied Like Dissatisfied) "
End If
strSql = strSql & strwhere & strtcheck
So what I want and I can't get it to work is, if Me!checkbox is true, than the Satified Vs Dissatisfied must be equal to Dissatisfied and then I want to pass it to the strSql, however when i run it in Access it doesn't work, can someone help?
If your string is intended to include a WHERE condition for a field named Satified Vs Dissatisfied, enclose the field name in square brackets. And enclose the string you compare to the field in quotes.
strtcheck = " ([Satified Vs Dissatisfied] Like 'Dissatisfied') "
Actually that condition doesn't use pattern matching, so you could just use = instead of Like.
strtcheck = " ([Satified Vs Dissatisfied] = 'Dissatisfied') "
Also you likely need to include SQL AND to combine that condition with the other WHERE conditions.
strtcheck = " AND ([Satified Vs Dissatisfied] = 'Dissatisfied') "

MS-Access 2003 - Expression in a Text Box on a form

just wondering when using an expression on a form in a text box, to return a value from a table, can the expression have multiple tables in the expression to return the value?
the tables are linked and I can return the value in a query, so I figured that Access would be able to do it with this method as well????
=DSum("[tblMain]![Revenue]","tblMain","[tblMain]![Quarter]=3 AND [tblMain]![Region]='NorthEast'" AND [tblOffice]![Location]='NewYork'")
this is the expression that I entered into my text box, without the reference to the 2nd table it works fine, but once I had it, I get the flickering error message in the text box (just as on a report)......
I know this method is probably used more in reports than forms, but I am novice, and trying to come up with a dashboard solution that returns lots of facts quickly per department. I am using this in the "Control Source" field of the data tab of the properties window, not VB. Mainly because I do not know how to get it to work with VB.
Thanks for the help as always!
As far as I know, you cannot refer to more than one table or query in a domain aggregate function. As grazird says, how are these tables related? Let us say it is on tblMain ID, you can build a query called, say, qryMainOffice, the SQL (SQL View, Query Design window) would look something like:
SELECT [tblMain].[Revenue],[tblMain]![Quarter],[tblMain]![Region],
[tblOffice]![Location]
FROM tblMain
INNER JOIN tblOffice
ON tblMain.ID = tblOffice.MainID
DSum would then be (remove line break):
=NZ(DSum("[Revenue]","qryMainOffice",
"[Quarter]=3 AND [Region]='NorthEast' AND [Location]='NewYork'"),"Not found")
You could also use a recordset or query in VBA to return the value.
EDIT re COMMENT
To use the above in VBA, you either need to add parameters or use a string:
''Reference: Microsoft DAO 3.x Object Library
Dim rs As DAO.Recordset
Dim db As Database
Dim strSQL as String
Set db= CurrentDB
strSQL = "SELECT Sum(t.[Revenue]) As TotalNY" _
& "FROM tblMain t " _
& "INNER JOIN tblOffice o " _
& "ON t.ID = o.MainID " _
& "WHERE t.[Quarter]=3 AND t.[Region]='NorthEast' " _
& "AND o.[Location]='NewYork' " _
'' I have use aliases for simplicity, t-tblMain, o-tblOffice
'' If you wish to reference a control, use the value, like so:
'' & " AND [Location]='" & Me.txtCity & "'"
'' Dates should be formated to year, month, day
'' For joins, see http://www.devshed.com/c/a/MySQL/Understanding-SQL-Joins/
Set rs = db.OpenRecordset strSQL
If Not rs.EOF Then
Me.txtAnswer = rs!TotNY
Else
Me.txtAnswer = "N/A"
End If
You can also use different queries to return several results that can be shown with a list box or a subform:
strSQL = "SELECT TOP 5 o.[Location]," _
& "Sum(t.[Revenue]) AS TotRevenue" _
& "FROM tblMain t " _
& "INNER JOIN tblOffice o " _
& "ON t.ID = o.MainID " _
& "WHERE t.[Quarter]=3 AND t.[Region]='NorthEast' " _
& "GROUP BY o.[Location]"
The above would return revenue for quarter 3 for all locations in NorthEast region. If you want the top values of each group, you are looking at a more complicated query, which I will leave for now.
How are these tables related? Can you describe the relationship and any primary/foreign keys?
Also, referencing the table name is not necessary in the first parameter of this function (since it is already taken care of in the second one).
For example, your code could be:
=DSum("Revenue","tblMain","Quarter=3 AND Region='NorthEast'" AND [tblOffice]![Location]='NewYork'")
Just trying to save you some keystrokes and increase its readability. :)
