SQL toolkit

I've added sqldistsupp.dsn and sqldistsupp.exe in my distribution kit to configure a database's connection automatically.
In order to get connection to SQL Server instead MS Access what changes in the sqldistsupp.dsn I have to do?
Thanks

Hello YG,
I have not been able to find an example for this, but you may want to check out the LabWindows CVI SQL Toolkit Reference Manual. Chapter 2 has more useful info on the database connections that are possible.

Why do I get a class conflict between the Prepare SQL.vi and the Get Column Name.vi with the SQL Toolkit compatibility vis from the Database Connectivity Toolkit?

I have done extensive programming with the SQL Toolkit with LabVIEW versions through 6.1. My customer now wants to upgrade to Windows 7, so I am trying to upgrade to LabVIEW 2009 (my latest purchased version) using the Database Connectivity Toolkit, and the SQL Toolkit Compatibility vis. Everything seemed to be going okay with the higher level SQL operations, but I ran into trouble with the Get Column Name.vi.
The pictures below show the problem. The original SQL Toolkit connected the Prepare SQL.vi with the Get Column Name.vi with a cluster of two references, one for connection, and one for sql. The new compatibility vis have a class conflict in the wire because the Prepare SQL.vi contains a cluster with connection, and command references, but the Get Column Name.vi expects a cluster with connection and recordset references.
How do I resolve this conflict?
Thank You.
Dan

I've never worked with the old version of the toolkit, so I don't know how it did things, but looking inside the SQL prep VI, it only generates a command, and the the column name VI wants a recordset. I'm not super familiar with all the internals of ADO, but my understanding is that is standard - you only have the columns after you execute the command and get the recordset back. What you can apparently do here is insert the Execute Prepared SQL VI in the middle and that will return what you need.
I'm not sure why it worked before. Maybe the execute was hidden inside the prep VI or maybe you can get the column names out of the command object before execution. In general, I would recommend considering switching to the newer VIs.

Help, Cannot connect to ODBC database using SQL Toolkit!

Hello All,
I am toying around with the SQL Toolkit evaluation (2.2 + the patch) and I am having difficulty.
I ran the example program "connect" and it seems to work fine.
However, I try to write my own program and I keep getting the same message:
"Function DBConnect: (return value == -10 [0xFFFFFFF6]).
Native error code - 2147467259 0x80004005
The message differs from time to time, but the return value is constant.
I am using both Microsoft SQL Server 2012 and MySQL.
For MySQL I have installed the latest ODBC connector, 5.3.4. Inside the Control Panel/Data Sources(ODBC), I have a DSN named test_mysql in both User DSN and System DSN.
I ran a test on the connection and the test passes. I am not sure if I should use the ansi or unicode driver, I have tried both with the same success.
I am not sure I had configured the SQL Server connection properly, and will attempt that again.
My CVI Code is simple enough:
hdbc = DBConnect ("DSN=test_mysql");
Every time I get a -10 from DBConnect. Either I have something configured wrong or I am missing something.
Does anyone have any suggestions?

Update 2:
After getting off the phone with Tech Support the problem has been identified!
LabWindows SQL toolkit requires 32 bit DNS. My PC is a 64 bit, so my DNS manager defaulted to 64 bit.
I needed to use the 32 bit DNS manager when working with the toolkit.
Once I created my DNS connections using the 32-bit version of the ODBC Datga Source manager, everything worked fine.

How can I use SQL TOOLKIT concurrently with Database Connectivity ?

I have installed LabVIEW 6.1 with the Database Connectivity Toolkit and the SQL Compatibility Toolkit (e.g. _SQL folder). I am trying to make the transition from the SQL Toolkit VIs to the Database Connectivity toolkits, but for compatability with existing systems I would like to be able to run the two sets of VIs concurrently (but not in the same app).
When I read into 6.1 a connection VI that I wrote with LabVIEW 6.0 and the SQL toolkit the connection reference type gets changed from a number to type connection (see attachments) . Does compatbility mean that my SQL toolkit VIs are converted to a form compatible with the new ADO ?
Can I use the SQL Toolkit VIs or the Database connectivit
y VIs in the same installation of 6.1 ?
Can I have the SQL Toolkit VIs appear on the functions pallette and function as they did when only the SQL toolkit was installed ?

In response to your #2 below:
Actually it is possible to have the old SQL Toolkit and new Database
connectivity in the same installation of LabVIEW. I have only tried it on
6i, but don't see why it wouldn't work on 6.1. The trick is not to install
the SQL toolkit compatabitily VI's. The old SQL toolkit uses the Intersolve
dll through ODBC while the new Database connectivity uses ADO so it is
possible to use both methods not only in the same LabVIEW install, but it
the same running application. It has been a while since I originally did
this, so I am posting only to mention that it is possible and not exactly
how to do it. If anyone is interested in more details just respond.

I want to use the SQL Toolkit of NI and SQL Server as my databasis on a server. Do I need to install a client in each computer I want to handle the data into SQL tables or I need only a ODBC driver?

I want to use the SQL Toolkit of NI and SQL Server as my databasis on a server. Do I need to install a client in each computer I want to handle the data into SQL tables or I need only a ODBC driver?

You only need the ODBC driver on each computer. If you are distributing the SQL Toolkit app as an executable and do not install the whole toolkit on each computer, you'll need the SQL Toolkit support files. This is about a dozen files. You can get the list at http://digital.ni.com/public.nsf/websearch/b814be005f9da9258625658700550c75?OpenDocument.

Set password for DSN (SQL Toolkit)

Hello everybody,
I'm working on WinNT4.0 with LV5.1.1 and SQL Toolkit v5.0. I've got an ODBC
DSN for an Oracle7 database. I'm asked for a password when I make a connection
to the DSN, which I now enter manually.
After that I can read and write data to the database.
Does anybody know how I can set the password automatically with the SQL Toolkit
to avoid the dialog ?
Otherwise there always has to be a user present when a connection to the
database is made, which would be very unkomfortable.
Is there any solution ?
Many thanks in advance.
Ralf.

Wire a string constant to the SQL Connect VI's Connection Parameters input
and include the appropriate connection parameters. For MS SQL7 the info
looks like this:
UID=username;PWD=password
I don't use Oracle, but I imagine it would be similar. If your unsure, create
a file DSN using the ODBC administrator in NT and mimic the parameters it
creates.

How to compact and repair a MS Access database with NI CVI 8.5 (and SQL Toolkit)

Hello
I'm using the SQL Toolkit with CVI 8.5 for accessing MS Access Databases.
Is there a possibility to compact and repair the .mdb file with CVI?
Thanks in advance.

Hello Ulrich,
with compact and repair I mean the MSAccess function "Compact and Repair".
Please follow the link below for more details:
http://office.microsoft.com/en-us/access-help/compact-and-repair-an-access-file-HP005187449.aspx
Normally you can execute this function directly in Access or with the Windows ODBC Data Sources Administrator => "Control Panel" => "Administrative Tools" => "Data Sources (ODBC)"...
I want to execute this function via cvi code and not by hand ;-).
Thank you for your support.

MySQL database with SQL Toolkit

Hi,
we are using CVI 2012 and the SQL Toolkit 2.2 and we want to connect to a MySQL database.
The MySQL database was created with MySQLServer. When we try to connect with DBConnect we get an error.
How can we connect the MySQL Database?
What do we have to type in the connection string in DBConnect? Is it the name of the database, the path to the database or anything else?
Does any one have experience with the SQL toolkit?
Thanks in advance

You need to install the mysql connector odbc and then create an ODBC dns for your database.

LabWindows CVI and SQL Toolkit cursor/schema error

We are using CVI 8.5 and SQL Toolkit 2.0.6 to write data to a SQL Server 2008 database. We are utilizing the Microsoft ODBC SQL Server (non-native) driver. We build a transaction that calls stored procedures on the database to write the data. Occasionally we get the following error:
"Could not complete cursor operation because the table schema changed after the cursor was declared"
The error is unusual since we only use one cursor and it is in a stored procedure that gets called by other software hundreds of times a day and never fails. Our database is also designed to only append records, not change existing ones. We're trying to pinpoint the error and I'm wondering if anyone knows if the SQL Toolkit uses cursors to build transactions or if this error has been seen by others. Since upgrading the toolkit or drivers takes a lot of effort, I want to make sure that I understand the problem before I start throwing darts at it. Thanks in advance for any insight.

I've attached the function that's failing. Unfortunately, the code isn't designed with much resolution as to what SQL toolkit call failed, since these calls haven't failed once validated and put into the production environment. Can you tell if any of these functions use a cursor. I could certainly try adding more resolution to the error handling, but since we've only seen errors occasionally in the production environment, I'd need to release a temp version and monitor it. Let me know what you think. Thanks.

SQL toolkit 2.2 Stored Procedure Memory Leaks

Hi
we are using CVI 2012 and SQL Toolkit 2.2. My db is "MySql 5.5.28" and I use "MySQL Connector/ODBC 5.2(w)"
I use only stored procedure (with and without the output parameters). If I call continuously a stored procedure,
with Sql toolkit code, I have memory leaks!!
My code (without error handler) is:
// iDbConnId is the handle of DBConnect() called when program starts
iStmt = DBPrepareSQL(iDbConnId, "spGetPrData");
DBSetStatementAttribute(iStmt, ATTR_DB_STMT_COMMAND_TYPE, DB_COMMAND_STORED_PROC);
DBExecutePreparedSQL(iStmt);
DBBindColLongLong(iStmt, 1, &llPrId, &lStatus1);
DBBindColInt(iStmt, 2, &iIpPort, &lStatus2);
while(DBFetchNext(iStmt) != DB_EOF)
//get data
DBClosePreparedSQL(iStmt);
DBDiscardSQLStatement(iStmt);
If I call the same stored procedure by sql code ("CALL spProcedure()")
I don't have memory leaks!!
The code is (without error handler):
// iDbConnId is the handle of DBConnect() called when program starts
iStmt = DBActivateSQL(iDbConnId, "CALL spGetPrData();");
DBBindColLongLong(iStmt, 1, &llPrId, &lStatus1);
DBBindColInt(iStmt, 2, &iIpPort, &lStatus2);
while(DBFetchNext(iStmt) != DB_EOF)
//get data
DBDeactivateSQL (iStmt)
It seems to me that the DBDeactivateSQL function free the memory correctly,
while the functions DBClosePreparedSQL and DBDiscardSQLStatement do not release properly the memory,
(or I use improperly the library functions!!!)
I also have a question to ask:
Can I open and close the connection every time I connect to the database or is it mandatory to open and close it just one time?
How can I check the status of the database connection, if is mandatory to open and close the db connection just one time?
Thanks for your help.
Best Regards
Patrizio

Hi,
one of the functions "DBClosePreparedSQL and DBDiscardSQLStatement" is a known problem. In fact, there is a CAR (Corrective Action Request 91490) reporting the problem. What version of the toolkit are you using?
About this function you refer to the manual:
http://digital.ni.com/manuals.nsf/websearch/D3DF4019471D3A9386256B3C006CDC78
Where functions are described. To avoid memory leaks DBDeactivateSQL must be used. DBDeactivateSQL is equivalent to calling DBCloseSQLStatement, then DBDiscardSQLStatement. DBDeativateSQL will work at all for parameterized SQL, as well.
Regarding the connection mode advice to you is to open the connection once and close it at the end of your operations. What do you mean with "state of the database connection"? Remember that if you have connection problems or something goes wrong, the errors appears in any point in your code where you query the database. Bye

Hi !
Thank you very much for your reply.
That line I want to set the time format and it could use the funtion
DBBindColChar (hstmt, 2, 27, date, &status, "");
I do not know it is right or wrong.I could not see any response in this line.
My original idea is recording the date and time when saving the datas.
Would you have any good idea according to it ?

PL/SQL TOOLKIT + STORED PROC / APEX VAR

Hi guys,
i can't find a good example on how to use pl/sql toolkit with var taken from the page or stored proc:
An example. I want to build a thumbnails of img:
Let's say i use this to build my image grid:
for x in 1..5 loop
htp.p('<table border=1><tr>');
for x in 1..5
loop
htp.p('<td>a</td>');
end loop;
htp.p('</tr></table>');
Now how i would like to use a code as follows to
<img src="#OWNER#.display_thumb?p_photo_id=' (PHOTO_CATALOG_ID,80) || ' "/ WIDTH=100 HEIGHT=100>'
Assuming that all my code is working how should i rewrite the <td>a</td> tag with an img src tag
a)htp.p
b)htp.img
Other question: is apex developed using pl/sql toolkit?
Thanx a lot for this

SQL Toolkit -- problem searching Date/Time field in Access

I have got an application where I need to query a database (Access) between
two dates (usually the same date, a couple of hours apart). I have set up
the date field within Access as a 'General Date' but can't seem to get the
right format on the SQL query. I am always getting some error. I enclose
the date with {}, '', [], and () (and anything else I can think of) and I
still get a problem. It is now to the point where I think it might be a
problem with SQL Toolkit and Access working together.
I tried making the Date field into a string field (instead of a Date field),
but I can't search between time (I can search between dates, but not date
and time i.e. MM/DD/YY 00:00:00).
Any ideas?

Sorry, the database type is Access.
I just tried the following query SELECT * FROM ValveMeritData WHERE MeritTestDateTime >= '2006/05/01 13:24:28'
and SELECT * FROM ValveMeritData WHERE MeritTestDateTime >= '2006/05/01' (which gave a data mismatch error).
I am going to try the query in access now. I had pretty good success with other types of queries, just writing them in
Labview and testing.
Any other suggestions?

Data to sql server using labview and labview sql toolkit

Hello everyone,
I am using mssqlserver 7.0, labview 6.1 and labview sql toolkit.
I am getting error while i try to store (large) data of size more than 4000bytes. Has anyone come accross such problem .
Looking for your solutions or suggestion for the
above said problem.

Check if the threshold is actual 4095 or 4096.
If so it is probably a default size of the field you are trying to write. If so, change table properties.
