I have a routine built to take query results and write them to an xls file. The problem is that I am only getting the column headers and 2 of the 3 rows of data. What am I doing wrong that the last row of data is not being written to the file?

I am currently attempting to write a program that will take a SQL query saved as a .sql or .txt and execute it against a specified database, and output the results to file. I have seen some sample code of executing a SQL query line by line,
and writing individual results to file.
The query that needs to be run is only reading information from multiple tables, but is pretty lengthy to do line by line. Is it possible to execute or read the whole query from the .sql file, or a text file, and run it against a specified database, and
have the results of the query output to file in vb.net?
We have a directory with a list of PDF files.Each file name has an Employee ID (eg 001213.pdf). What I need to do is loop through each file name, grab the employee id (001213) and pass it to Oracle query. The query wilbasically retrieve employee data (Firstname, lastname etc).

If this is in the wrong section, I have a program that queries a database and puts the info in a specific format in a txt file. Now my problem comes w/ how to format the date.
Should I format the date in the SQL query OR is there a way to take the result from the query and format sometime before it is writen to the txt file? I'm not exactly sure how to do either. Would I need a subquery to get the desired date format?

I think probably the biggest help would be an explaination of what the code in bold is actually doing. I pulled this from a book but don't think I completely understand.

UPDATE: I've verified that the issue is with the statement where sh.is_available = 1, which doesn't make sense since this is a bit field.
