Direction to create a frontend/GUI for simple SQL query? - sql

I work on a team that creates adhoc SQL queries for a large database for users that are performing research. These searches are done with Excel via ODC files with ODBC connection.
I'm looking for a program / best language suggestion to create an app for users to run the simpler queries themselves that they request. Basically a window that has a few text boxes for the variables as well as some date range boxes. Runs query and exports to a spreadsheet etc.
So far I've only found tools that run the raw SQL query code itself.
Thanks in advance. -Steve

Transferring data from Excel to SQL multiple indexed tables

I have like 20 tables and one general table in SQL. That main table has indexes in in its columns. Using these indexes I create a view by getting the data from other 20 tables.
My question would be what would be the most efficient way to create a process of updating all of those tables accordingly using an Excel source. It should be future proof (new excel data being inputted once a month e.g.).
If it is a SSIS package how would it look, maybe you have any examples of something similar?
Thank you for the help.
I for one do not like SSIS. I find it a pain to troubleshoot, but for some tasks it's fine. If I were you I would:
Use the data import wizard from within Microsoft SQL Studio to import the Excel file.
Simply get the data into a staging table in SQL.
You'll have the option to save this as an SSIS package, good for automation
Now, write a pile of SQL to sort and update the data as you wish. Perhaps make a series of stored procedures
Create a job in SQL that runs your package, and then runs each stored procedure
Writing a solution in this fashion will allow you to troubleshoot each step and make reporting easy. You can just do the whole thing is SSIS but like I said, I'm not a fan of that tool. I like my code on the command line as much as possible for troubleshooting :)
I used this app from windows store to convert Excel into SQL script.
Then send script to our DBA.

Export SQL code from Excel into SQL

My skill level: basic user of VBA, know next to nothing about SQL (though I’ve recently learned how to execute code, etc).
I’ve created a user interface in an Excel worksheet to allow user input of report variables (dates, etc). These pass into a second Excel worksheet that, through the use of various Excel statements, creates the necessary SQL code. My macro then copies this worksheet and opens Microsoft SQL Server 2008 Rx via a shell command. Currently, I then manually click “connect” on the resultant Microsoft SQL Server 2008 R2 connect-to-server window (which does not need a password, just requires me to click “connect”), I create a new query, I paste the code in and then execute in SQL. So it is these latter steps (opening SQL, click “connect”, copy/paste code, execute) that I’m trying to automate via VBA.
To offer more context, once the SQL code has run, I then have a second macro that uses the Excel Data Connection wizard to bring the resultant SQL data back into my worksheet. This is working well.
I’ve researched this for several days on various boards. None seem to observe my approach of creating the code in Excel (probably because it is an inelegant approach). Or the post responses are beyond my skill level to understand. But I do fear that I’m asking a question that has been answered before (apologies in advance).
Thanks for whatever advice/time can be offered.
I’m using:
Excel/Office 2010
Microsoft SQL Server2008 R2 (is this the same as Microsoft SQL Server Management Studios? My SQL application shows both names)
Microsoft ActiveX Data Objects 6.1 Library (this is NOT currently checked off. One post I saw referenced the need for this. I have multiple prior AciveX Library versions available as well.)
What you're doing is very ingenious, but it's probably not necessary. Excel has a number of features for importing external data.
I would look at the Data tab in Excel and the From Other Sources section of the ribbon. You have at least three options: the From SQL Server, From Data Connection Wizard, and From Microsoft Query options.
All of these will set up a connection to a database server and execute SQL against it. They return data to your spreadsheet in different ways.
Where VBA will come into play again is in automating the generation and parameterization of the queries these will execute.
But I would set up something that works, with constants for your parameter values, first, so you get an idea of the possibilities, and then read and research dynamically setting your SQL with VBA.
You might also investigate PowerPivot, by the way.

Crystal Reports vs. SQL Queries

I'm a programmer (mostly C++) who has moved into a non-software workplace. However, I don't have much experience with database stuff at all.
TL;DR: If we compare Crystal Reports to just writing scripts that execute SQL queries and parse the results, is there anything that CR can do that isn't possible via SQL queries & scripts? I'm talking purely in terms of extracting data - not making pretty documents.
Detail:
At my workplace they have a process where you run a bunch of Crystal Reports, modify the date range to the current month, manually export each to excel, delete the rows and columns that aren't needed, and then cut and paste into a summary excel document that is used by management.
To me, this is pretty crazy and stupid. I'd like to automate/script most of it.
So I have two options:
Learn Crystal Reports and try to modify the existing reports to be more automated.
Dump CR and just learn SQL and do the whole thing programmatically with scripts working with CSV files or something.
I'd much rather learn SQL since it's more general and useful. But I need to be assured that I can get the data output that I need (without writing a million lines of code to reproduce CR myself.)
So yeah, I'm looking for an answer like, "The two are equivalent. Anything you can do in CR you can do easily via scripts and SQL," or "If you need to group records into categories based on a parameter and then sum their one of their fields, then CR will do it much more easily than raw code," to push me in one direction or another.
Edit:
Some additional detail. At the moment my crystal reports run a database query, and then crystal does things like, "don't display the records that are returned, instead group the records by Field A and then display the count of how many records in each group."
Is functionality like this difficult to reproduce via SQL coding? I wouldnt want to have to write a python (or whatever) script to parse and manipulate the data from plaintext CSV, for example.
You can't just compare SQL and CR - they have different purpose. SQL (in this context) is data source, CR is pretty output formatter. For excel you would need data, not formatted output. Excel combined with SQL can give you all CR options (dynamic crosstab reports, charts etc) what you can't get directly from SQL data.
BTW, creating SQL views or procedures is often needed to overcome CR limitations; from this standpoint SQL has lot of more options than CR.
I personally would go with SQL+Excel route. In our company we're using simply SQL+CR without postprocessing, sometimes SQL+Excel. Our customers are using different approaches.
But like said by other people, choice of tools depends on more things. Who has to redesign reports? Who will maintain these reports? How often requirements change? Are there more uses for CR reports besides sourcing Excel tables? Who will be waked up at night, if reports do not work?
Management perpective:
In many I will say mostly cases management does not know SQL. So if a manager for E.g.HR wants to know staus about something then how he will get that status?? This is where Crystal reports come into picture, Using crystal reports they do not have to worry about SQL; they will just enter required fields and get their data.
Programmer perspective:
Simple data outputs can be achieved through SQL but consider a scenario where you need to pull details as well as summary. I agree it can be done via SQL but consider the overhead of time and proficiency required to develop such output using sql. I bet it wont be that easy to develop such output using sql as compared to crystal. So I will say learn both SQL and crystal, you will get to choose the tool to apply for your requirement.
You can write SQL and drop it into the Crystal Report. Best of both worlds, and possibly faster performance than the drag-and-drop Crystal functionality.
You will see some response time lag when the report runs.
There are actually a few things that Crystal Reports can do that are very tricky using plain SQL Queries as Crystal Reports can access the entire dataset in a single formula and can do things at runtime.
However unless you have some really crazy complex Crystal Reports I would recommend building a tool in Excel that can one click the info straight into a new sheet.
I did this and it got me a promotion, not kidding :P
I have a custom Excel Addin I can give you code to that basically does this:
On open, connects to the database and downloads a list of menu options connected to views and procedures
Adds these menu options into a new Ribbon tab within Excel
When one is clicked, runs the view and dumps the entire dataset (properly formatted) into a new sheet
Advantage of this is you can update the main menu list and each view it references without making any changes to the file or re-issuing anything to everyone.
Crystal could be helpful if you want to create a document with a specific layout , logos etc. and show some data on it. Export to excel from Crystal repot is not easy - usually there are a lot of empty columns and rows and each report should be tweaked to avoid that.
If you need to export some data from a SQLServer database to excel your best option will be SSIS ( I guess you have a license for SQL Server). If you don't have license for SSIS or you are using for example Access database there are also some inexpensive tools, which can retrieve data from any database ( not just SQLServer) and export it to excel. I would suggest you to check this one: http://www.r-tag.com. It can run Crystal reports and SQL reports so you can start using your crystal reports immediately and start transforming them to SQL reports whenever you have time for that. Both reports could be exported to excel.
i fixed this by editing excel sql, Left(Column_maxLength, 250)
this resolved my issue
in my case if even if i read left 250 character is enough

End user friendly sql query run inside excel

I have an Oracle 11G database and sql developer 3.0.04. I have a SQL query which collects useful data for users across a system. The query prompts for two values (using the "&" trick) and then returns a number of columns and rows reflecting their choices. For example, entering "2" at the location prompt, will use the sql query to pull revelant data for that particular location only.
I can connect to the database using Excel 2003. (ODBC Connect) I want to store an excel file on the server, that my users can access to run this query - (as sql developer wouldn't be suitable for these users, too complex)
We have Excel 2003 installed. What do I need to do to let users run the sql query from excel, which will show them the result also in excel?
Thanks!
For what it's worth...
I'd recommend just turning this query into a report in SQL Developer. There's nothing complex about that for your end-users -- they just click on the report they want to run, and it runs (output looks like a table, and they can export it if/as they choose from there). Distributing the report simply requires that you store on a share drive or email it to them (then they import it) -- it's a lot easier than it sounds, and also very convenient for distributing updates / additional reports. With reports, your users won't have to see the SQL, for example (unless they really want to), and the prompts will appear to them as little dialog boxes with plain-english messages (whatever you want them to say).
Anyway, you might find this easier to support / modify / maintain, and I think your users should be happy enough with it (unless they're really grumpy types... :-)

How to automatically report an SQL query into an Excel spreadsheet in regular intervals

I am currently working on an application that is meant to be relaying realtime data on screens. I would like to know how to automatically report the resultset of a SQL query to a Microsoft excel sheet using SQL Server 2005.
Many thanks for your audience and anticipated help.
Cheers,
Tunde
Probably the simplest way of exporting from SQL Server to Excel in TSQL with OPENROWSET. Find out more.
Then schedule the running of the TSQL using SQL Server Agent.
The best would be to write a program Or even a excel Plugin in .net that writes your query result to a csv file at certain intervals that you can open with excel.
