THE ERROR -

You should remove the + from your code. That + is meant to indicate that it is the continuation of a line and is merely aesthetic.
Use ?factor for information on parameters and syntax for using a function.

'=' expected near var_y

I have this code:
function var_leafdrop(var_inc, var_restpos)
If var_y >= var_restpos then
var_y = var_restpos
else
var_y = var_y + var_inc
end
return var_y
end
I get error:
error 18: '=' expected near 'var_y'
18 being the line:
If var_y >= var_restpos then
I've tried:
Changing the variable name
Changing its declaration
Removing the if then block
Moving the entire function to the beginning of the script file
This is using the built in script editor for Watchmaker.
I can't see any error!? I just don't get it. Is this some dumb idiosyncrasy with Watchmaker...?
As mentioned in the comments, Lua is case sensitive.
So use if instead of If.

ODI - Call SQLLDR via Jython on Windows Shell

I'm testing some interfaces with Oracle Data Integrator 11g on Windows 7.
All the interfaces use the LKM MSSQL to Oracle (BCP/SQLLDR), while running them I got an error on the "Call SQLLDR via Jython" command. After some invesetigation I found that the root of the problem was the following line of code:
exitCode = os.system(sqlldr + " control=" + tempSessionFilePrefix + ".ctl log=" + tempSessionFilePrefix + ".log " + "userid=" + "<% out.print(odiRef.getInfo("DEST_USER_NAME")); %>" + "/" + "<% out.print(odiRef.getInfo("DEST_PASS")); %>" + tnsnameOption + " > " + tempSessionFilePrefix +".out" );
It should run on the Windows Shell a string in the form of:
sqlldr control=control_file.ctl log=log_file.log userid=ODI_STAGE/ODI_STAGE > shell_output.out
I did run the string generated directly on the command prompt and it worked without any problem.
So after playing a bit with the code, I couldn't make the os.system working so I replaced it with subprocess.call. I also have to remove the last part of the string where it attempts to save the ouput of the command prompt (> shell_output.out) to make the whole thing work:
exitCode = subprocess.call([sqlldr, "control=" + tempSessionFilePrefix + ".ctl", "log=" + tempSessionFilePrefix + ".log", "userid=" + "<% out.print(odiRef.getInfo("DEST_USER_NAME")); %>" + "/" + "<% out.print(odiRef.getInfo("DEST_PASS")); %>" + tnsnameOption], shell=True);
This one works smoothly.
Regarding the shell output, I suspect that the problem is the string part that starts with the '>' charcater that is parsed as part of the arguments of SQLLDR instead of a command to the prompt.
Now, while I can live without it, I would like to ask if someone knows any simple workaround to get also the shell output.
Ok I was finally able to get also the shell output.
I edited the "Call SQLLDR via Jython" command with the following:
from __future__ import with_statement
import subprocess
...
with open(tempSessionFilePrefix + ".out", "w") as fout:
exitCode = subprocess.call([sqlldr, "control=" + tempSessionFilePrefix + ".ctl", "log=" + tempSessionFilePrefix + ".log", "userid=" + "ODI_STAGE" + "/" + "<#=snpRef.getInfo("DEST_PASS") #>" + tnsnameOption], stdout=fout, shell=True);
Now everything work as intended.

SELECT * INTO Incomplete Query Clause

I seem to be doing something wrong in my OleDbCommand, but I don't know what it is. I am trying to create another table in my access database that is exactly the same as the first but with a different name, by copying everything from one and using SELECT INTO. I don't know why it doesn't work.
OleDbCommand copyAttendanceCommand = new OleDbCommand("SELECT * INTO '" + "Attendance " + DateTime.Now.Day + "/" + DateTime.Now.Month + "/" + DateTime.Now.Year + "' FROM Attendance",loginForm.connection);
copyAttendanceCommand.ExecuteNonQuery();
The Error message that I get says "Syntax error in query. Incomplete query clause." Does anyone know what that means?
Table or field names with spaces are not specified with '' around them, but with square brackets.
Your command should be:
"SELECT * INTO [Attendance " + DateTime.Now.Day + "/" + DateTime.Now.Month + "/"
+ DateTime.Now.Year + "] FROM Attendance"
You may even format your date to make the code more readable:
string today = DateTime.Today.ToString("d'/'M'/'yyyy");
string sql ="SELECT * INTO [Attendance " + today + "] FROM Attendance";
OleDbCommand copyAttendanceCommand = new OleDbCommand(sql, loginForm.connection);
copyAttendanceCommand.ExecuteNonQuery();

Understanding the output log's auto layout data

I'm debugging a crash that I believe is auto layout related. When the crash occurs, I get an enormous dump of information on the output area that begins like this:

I would like to understand this data better as an aid to debugging my problem.
Is there a document or a posting that I can access that explains the format and meaning of this data?
Like, for instance, what does something like <500:1,250:-1> represent?
What is a negError?
And, most importantly, can something like {id: 3600} be tied back to a specific control that auto layout is laying out for me?
I'm particularly interested in the last questions because I've read here that very small numbers, when seen in these dumps, can indicate a crash due to accumulated loss of floating point precision in the auto layout engine.
You'll note that I have such a number on the very last line of my output data. So, if I can relate {id: 3600} back to one of my controls, I hope that will put me close to the origin of the problem.

How to insert line break in a return statement for D3

I have the following code d3 code:
tooltip.select("#popupCount").text(function(){
if (varToGraph == "rough_top_cost"){
return " " + textValue + ": $" + addCommas(allCountyData[countyName][varToGraph]) + "\n" +
"Count:"
}})
I want the word count to appear on a new line. However, the above code results in everything being on one line. How can I get the output to be on two lines?
Thanks,
AH
Untested answer, but FWIW this may get close;
tooltip.select("#popupCount").html(function(){
if (varToGraph == "rough_top_cost"){
return " " + textValue + ": <br/>$" + addCommas(allCountyData[countyName][varToGraph]) + "\n" +
"Count:"
}})
Working from the example provided on page 80 of D3 Tips and Tricks which includes tooltips with line breaks.
Uses html element instead of text which allows line breaks. Check out the document for more detail.
