This code works when the connection is made to an accdb database:
Dim customer = connection.Query(Of Klantgegevens)("Select Actief,Onderhoudscontract From Klantgegevens Where Klantnummer=#Idx", New With {.Idx = customerId}).SingleOrDefault
But the code below gives the error about the Idx parameter when the connection is made to a SQL server database that has a table with the same structure:
Dim customer = connection.Query(Of Klantgegevens)("Select Actief,Onderhoudscontract From [dbo.Klantgegevens] Where Klantnummer=#Idx", New With {.Idx = customerId}).SingleOrDefault
What is going wrong here? I had hoped that by using Dapper I would be able to write database agnostic code. But it seems that is not the case!
If you are using an ODBC/OLEDB connection, then my first suggestion would be: move to SqlClient (SqlConnection). Everything should work fine with SqlConnection.
If you can't do that for some reason - i.e. you're stuck with a provider that doesn't have good support for named parameters - then you might need to tell dapper to use pseudo-positional parameters. Instead of #Idx, use ?Idx?. Dapper interprets this as an instruction to replace ?Idx? with the positional placeholder (simply: ?), using the value from the member Idx.
This is also a good fix for talking to accdb, which has very atypical parameter usage for an ADO.NET provider: it allows named parameter tokens, but all the tokens all replaced with ?, and given values from the positions of the added parameters (not via their names).
I'm trying to build a Data Integration job uses pass through to extract data from a view in a MySQL database.
Wev'e been using pass through a lot in the project, mostly extracting data from Redshift,
however with MySQL I was not able to do make it work properly.
It keeps complaining a table is missing even though when pass through is off, view is found and data is extracted...
tried every trick I know, starting from enabling case-sensitive DBMS object names, to manually remove single/double quotes from the statement just in case MySQL confuses confuses it with something else...
No luck.
ODBC driver is [MySQL][ODBC 5.3(a) Driver][mysqld-5.5.53].
Ran on a Windows environment.
Any idea how to solve this?
Thank you in advance.
EDIT
So, first of all, one correction (even though not that important - I extract from a view, not a table).
This is the code generated by SAS Create Table transformation, pass through enabled. I only put an asterisk instead of the full list of columns:
proc sql;
connect to ODBC
(
READBUFF=10000 DATASRC="cmp.web_api" AUTHDOMAIN="MYSQL_CMP_Auth"
);
create table work."W7ZZZKOC"n as
select
*
from connection to ODBC

disconnect from ODBC;
quit;
And again, when I extract data without pass through - works successfully,
I found out the problem was a column name exceeds 32 positions.
As SAS supports up column names up to 32,
the query fails to find PRIMARY_ACCOUNT_OF_THIS_CUSTOMER as the original column name is PRIMARY_ACCOUNT_OF_THIS_CUSTOMER__C.
EDIT
One more thing I found out is, MySQL doesn't like specifying schema name nor aliases.
Therefore,
From clause to only specify table name i.e : 'from v_bi_account' rather than 'web_api.v_bi_account'
and do not use aliases i.e use 'from v_bi_account' rather than 'from v_bi_account as v_bi_account'
Thank you guys so much for your help.
I'm having difficulties in retrieving and displaying records from a table in a database. I'm using a MySql database and VB.NET 2012.
I'm getting the following error message
"End of statement expected"
Remove the space between Form2 and _Load. Your SQL statement is also broken, the AND being in blue shows this. You have your single and double quotes confusing it, the statement is being ended before the AND due to incorrect syntax. In any case, you should, probably, be using
"SELECT * FROM bigregdb WHERE regID = '"1"' OR regID = '"2"'"
I am creating a SilkTest script in which am storing a string in a List of String variable
List of STRING FaultDn
This variable reads the string from a file.
FaultDn = ReadFile("C:\FaultDn.txt")
Then I try to connect to SQL database to retrieve a value by providing this string
HSQL hstmnt = DB_ExecuteSql (hdbc, "select Id from openview.dbo.OV_MS_Message where OriginalServiceId like #FaultDn")
But it returns an error
Error: (42000) [Microsoft][SQL Server Native Client 10.0][SQL Server]Must declare the scalar variable "#FaultDn".
Can you please help in correcting this SQL Query in SilkTest Script?
I think you need to change your query to
HSQL hstmnt = DB_ExecuteSql (hdbc, "select Id from openview.dbo.OV_MS_Message where OriginalServiceId like '{FaultDn}'")
The difference being at '{FaultDn}'. You need to add the curly braces so Silk Test interprets it as a variable name, and the quotes because it is a string literal within the SQL query.
What I'm not exactly sure about it whether you're intentionally passing the whole list into the query, if you just want to pass the first line, you should change it to '{FaultDn[1]}'.
We've just upgraded from Access 2003 to Access 2010 and string comparisons are failing with an invalid procedure call error when default conditions are used. I’ve recreated two presumably related problems in a new Access 2007 format database containing only the default table, a query with the SQL below and a module containing only the code below, so I seriously doubt that this is a corruption issue.
First the following sub fails on the If Then line with Run-time error 5: Invalid procedure call or argument
Option Compare Database
Option Explicit
Sub checkStrCmp()
Dim str As String
str = "s"
If str = "s" Then
MsgBox "works"
End If
End Sub
If I change Option Compare Database to Option Compare Text the sub works as expected, but this seems like a bad idea as I may want to preform text as well as numeric comparisons inside a single sub.
I’m also getting “Invalid procedure call” errors in string comparison functions inside of SQL. The Replace function is requiring the supposedly optional compare parameter.
Select replace("foo-bar-baz", "-", "|", 1,-1);
Generates the “Invalid procedure call” error
Setting the compare parameter to any of the available values (0 -3) works as expected:
SELECT replace("foo-bar-baz", "-", "|", 1,-1, 0);
produces “foo|bar|baz”
Has anyone else seen this? Is there a setting that needs to be tweaked? Any other ideas outside of “Database corruption” which is all I’ve been able to find via Google.
TIA
apoligies for the sloppy code blocks I can't for the life of me get them to work right.
UPDATE: I should have mentioned that I'm running XP Pro sp3.
The problem seems limited to databases I create on my box. When I opened the test database I created on my box from other workstations on our network I saw the issue, but was then unable to recreate it when creating a new database as described above on those workstations. The databases I created on the two other workstations (same OS and MS Office versions installed) also worked correctly when opened on my machine. I was also unable to recreate the issue when I inserted new modules in those DBs from my machine.
In short the problem seems to only exist on databases created on my machine (and in old 2003 format databases I've converted to 2007 format on my machine). My best guess is that my install is hosed but I’d like to have some idea of how and why before I approach IT with a request to reinstall Office. I’d also like to rule out a conflict with other software on my box.
Your code modules do not all need to share the same Option Compare setting. So you could place those procedures which should use text comparisons in a module which has Option Compare Text in its Declarations section.
However, I don't understand your statement, "I may want to preform text as well as numeric comparisons inside a single sub." According to Access' help topic, the Option Compare Statement is "Used at module level to declare the default comparison method to use when string data is compared". In other words, Option Compare has no effect on the comparisons of numeric values.
Edit: Since the problem is limited to Option Compare Database for database files created on only one machine, I'll suggest you check Access' "New database sort order" setting on that machine. Change it to a choice which starts with "General" if it is set to anything else. Then create a new database and see whether you still have the problem.
The reason for this suggestion is that Option Compare Database tells Access to use the database's codepage setting for sorting. And "New database sort order" can set the codepage to the one which never gives me such troubles. However, my understanding of codepage details is pretty shallow; I never change it and don't know what the consequences of other settings would be.
