double quotes in column name - can't assign column to a variable

I'm using a query in the SQL Query node and the query references a column called UNION. Well, UNION is a keyword in Oracle (no, I didn't create the table, it's Lawson table) so I have to put double quotes around the name for a valid query. The query works fine but the problem is trying to access the "UNION" variable in the query (jobGradeQuery_"UNION"). The Assign node does not like those double quotes. When I try to assign the UNION string to a variable I get an error basically stating that the expression is invalid.

Here's the query:

SELECT ACTIVE, "UNION", SALARYSTRUCTUREGRADE, PAYGRADE FROM LTM.POSITION WHERE HRORGANIZATION = '500'

Here's the assign statement:

foobar = jobGradeQuery_"UNION"

Is there a way to get around this?

thanks,
Steve

I'm already doing that. The problem is trying to assign the data in the "UNION" column to a variable in a processFlow assign node.

Because of the quotes in "UNION" you get a sysax error when trying to assign the column data to a variable.

e.g.

foobar is a varible of type string-

jobGradeQuery is tghe query node name.

the following assignment (done in an assign node) generates a systax error:

foobar = jobGradeQuery_"UNION"

I was wondering since the field variable name is actually jobGradeQuery_UNION and not just UNION if the quote was really needed? If so then does it make sense that the quotes should go around the whole variable name and not just the end: "jobGradeQuery_UNION" ?

If you're getting an error on an Assign node, leave the quotes out completely.

The field variable name is jobGradeQuery_"UNION". The double quotes are part of the variable name! It can't be changed as it was generated by processFlow. Other field names don't have quotes, as there are no quotes used for those columns in the select clause.

e.g.,

SELECT ACTIVE, "UNION", SALARYSTRUCTUREGRADE, PAYGRADE FROM LTM.POSITION WHERE HRORGANIZATION = '500'

results in variable names of:

jobGradeQuery_"UNION"
jobGradeQuery_ACTIVE
jobGradeQuery_PAYGRADE

etc.


Maybe I could edit the processFlow xml file and try to change the jobGradeQuery_"UNION" variable name?

I had a similar issue which I resolved by using an alias in the sql query:

SELECT ACTIVE, "UNION" as myunion, SALARYSTRUCTUREGRADE, PAYGRADE FROM LTM.POSITION WHERE HRORGANIZATION = '500'

Then the variable would be:

jobGradeQuery_MYUNION

Unfortunately the variable becomes

jobGradeQuery_"UNION" as myunion

that's even more of a mess!

I also tried

SELECT ACTIVE, "UNION" "myunion", SALARYSTRUCTUREGRADE, PAYGRADE FROM LTM.POSITION WHERE HRORGANIZATION = '500'

which produces a variable of

jobGradeQuery_"UNION" "myunion"

thanks,
Steve

Can you reference "union" as r_union instead?

sorry, I don't follow you. Do you mean changing the query, or?

In S3, when the column name in dbdef is an oracle reserved word, the column name inside oracle is preceded by r_.
I am not sure if that is the case with LTM, if so, you could change the sql from select "union" to select r_union.

If that is not the case I am fairly sure that you can use the column number in the variable instead of the name:
jobquery_2 (if this is the second column returned).

ah! I'm new to Oracle...

I tried your suggestion and LTM doesn't recognize the r_. I get an "invalid identifier" error.

Nor can I use jobquery_2, it's not recognized as a variable...

Have you tried escaping the double quote character, e.g. "=

I tried escaping the processFlow variable name when I made the assignment:

foobar = jobGradeQuery_\"UNION\"

and

foobar = jobGradeQuery_'"UNION"'

and

foobar = jobGradeQuery_""UNION""

none of the above works. Is that what you had in mind?

thanks,
Steve

Steve,
Try to assign in the free form JavaScript area in the Assign node.(using the 'Add JavaScript' button).
And then, after the JS Expression, in the same assign node, put - foobar = foobar (using the usual Lawson Assign way). This way you'll be able to see the value in the WU logs.

Hope this helps!

Cheers,
KK

KK,

Adding

foobar = jobGradeQuery_LTM.POSITION."UNION"

in the javscript tab of the assign node results in the error msg:

Error while validating expression: foobar = jobGradeQuery_LTM.POSITION."UNION" missing name after . operator.

If Iuse another query variable that doesn't have the double quotes it works fine.

thanks,
Steve

Steve,
You may already have a solution to this issue since this posting is a couple of years old. Anyway, I found that you can use \ as the escape character for the double quote. For example: "\"" + UNION + "\"" will give you the result as "UNION".
