I have a text box and search button same as stackoverflow, I have a field in database "Title", Now i want a sql query or some kind of logic which actually filter the string from "Title" field.
Eg. if I type "Stackoverflow is good website" in a searchbox.
Now I want those records from the table which contains
"Stackoverflow" OR "is" OR "good" OR "website".
I don't know if this is possible using a query or I have to write a logic.
FYI I am using salesforce.
I must have a reputation of 50 to comment so I'll post an answer instead. Using a dynamic query with the like comparison and or operator is the best method for the SOQL method. Depending on the size of your record sets I would look into front end solutions for better filtering methods. If you have several hundred results even, frameworks like angular or even custom solutions (show / hide) can create very nice user experiences with the data.

I would like to use parameters in Invantive control.
For example, I would like to retrieve only the hours, of Exact Online Project management which, are in the given data parameters.
There are three often used approaches:
Use parameters in the model editor.
Use Excel values.
Use data from the databases involved.
Model Parameters
To use parameters in the model editor, you define them in the model editor:
Select a unique code.
Possibly provide a default value (always string, use to_... or casting to change it in the queries).
Define list-of-values providing a quick pick.
The unique code is in general all in uppercase and in the format P_..., but as long it is a legal identifier anything should work.
To use them in one or more block queries or triggers:
Use the building blocks button.
Or type $P{CODE} in the SQL or trigger for Excel.
The values can be entered using the parameters button (the green funnel in the Control ribbon):
Please note that parameters are always bound as parameters, and not lexicographically substituted so you can NOT say: select * from $P{TABLE_NAME}.
Please note that parameters can be dependent on each other, so in the query for the parameter you can use another parameter. Such as first choosing the country of a project and then showing a list of projects in that country. But be wise, avoid recursion and other overly complex scenarios; the user will not easily understand it.
Excel values
To use Excel values, you can define them as follows:
Enter a value somewhere in Excel.
Optionally define a named range to make it easier to change the location.
You can of course assign lists as normal in Excel as a pop-up or other validations. Also cell locking works fine.
To use the actual value in a query or trigger of Invantive Control you can use the building blocks in the query editor or use something like select * from table where code = $X{projectcode} or select * from table where code = $X{B2&C2&D2}. The last one shows that you can also use other type of Excel expressions.
Note that Excel parameters are also bound as parameters to the query, but that they are also typed, so the following query can be different depending on the general format of the Excel cell:
select *
from table
where code like $X{CELL}
When cell is a text, the database or Exact Online in this case will retrieve:
select *
from table
where code like :ex0
With ex0 being a text such as '8%'. But when cell is a percentage, the contents might still display in Excel as '8%', but the actual query will be with identical to the outcome of:
select *
from table
where code like 0.08
Caused me some headaches, but typing is in general a useful feature, especially with dates.
Parameter using database data
Option 3 is practically not feasible with Exact Online, since they are little possibilities to create your own tables and/or fields.
On other platforms such as Oracle you might want to enter new rows in Invantive Control in Excel and them upload them on sync to provide parameters. Especially handy in case of complex risk models.
I have job in Talend that is designed to bring together some data from different databases: one is a MySQL database and the other a MSSQL database.
What I want to do is match a selection of loan numbers from the MySQL database (about 82,000 loan numbers) to the corresponding information we have housed in the MSSQL database.
However, the tables in MSSQL to which I am joining the data from MySQL are much larger (~ 2 million rows), are quite wide, and thus cost much more time to query. Ideally I could perform an inner join between the two tables based on the loan number, but since they are in different databases this is not possible. The inner join that is performed inside a tMap occurs after the Lookup input has already returned its data set, which is quite large (especially since this particular MSSQL query will execute a user-defined function for each loan number).
Is there any way to create a global variable out of the output from the MySQL query (namely, the loan numbers selected by the MySQL query) and use that global variable as an IN clause in the MSSQL query?
This should be possible. I'm not working in MySQL but I have something roughly equivalent here that I think you should be able to adapt to your needs.
I've never actually answered a Stackoverflow question and while I was typing this the page started telling me I need at least 10 reputation to post more than 2 pictures/links here and I think I need 4 pics, so I'm just going to write it out in words here and post the whole thing complete with illustrations on my blog in case you need more info (quite likely, I should think!)
As you can see, I've got some data coming out of the table and getting filtered by tFilterRow_1 to only show the rows I'm interested in.
The next step is to limit it to just the field I want to use in the variable. I've used tMap_3 rather than a tFilterColumns because the field I'm using is a string and I wanted to be able to concatenate single quotes around it but if you're using an integer you might not need to do that. And of course if you have a lot of repetition you might also want to get a tUniqueRows in there as well to save a lot of unnecessary repetition
The next step is the one that does the magic. I've got a list like this:
'A1'
'A2'
'B1'
'B2'
etc, and I want to turn it into 'A1','A2','B1','B2' so I can slot it into my where clause. For this, I've used tAggregateRow_1, selecting "list" as the aggregate function to use.
Next up, we want to take this list and put it into a context variable (I've already created the context variable in the metadata - you know how to do that, right?). Use another tMap component, feeding into a tContextLoad widget. tContextLoad always has two columns in its schema, so map the output of the tAggregateRows to the "value" column and enter the name of the variable in the "key". In this example, my context variable is called MyList
Now your list is loaded as a text string and stored in the context variable ready for retrieval. So open up a new input and embed the variable in the sql code like this
"SELECT distinct MY_COLUMN
from MY_SECOND_TABLE where the_selected_row in ("+
context.MyList+")"
It should be as easy as that, and when I whipped it up it worked first time, but let me know if you have any trouble and I'll see what I can do.
I am looking for a scripted/automated way (presumably VBA?) to take an Access query and generate some kind of savable, searchable, publish-able documentation on the data lineage. So if there were a bunch of layered/nested queries, or even passthrough queries, along the way I want a way to trace the final fields in the specified query back until I get back to the original source tables/fields.
Everything I've found seems to do database documentation focused on how the table relationships are configured. I'm looking for a way to get the documentation of the user-created portion, down to the field. I'm very open-minded on what format the output is in. I'm convinced this must be possible, but haven't had any luck yet.
I'm also open to recommendations for a third-party application if it could do this.
Thanks in advance!
Access does have a built in “dependency” feature. The result is a VERY nice tree-view of those dependencies, and you can even launch such objects using that treeview of your application to “navigate” the application so to speak.
The option is found under database tools and is appropriately called Object Dependencies.
The result looks like this:
While you don't want to use auto correct, this feature will force on track changes. If this is a large application, then on first run a significant delay will occur. After that, the results can be viewed instantly. As noted, not only do you have a hierarchical tree view, but objects in the tree view can be clicked on to launch the object in question.
And the above will work for a query that based on a query etc. all the way down to the base table.

This is a set of queries I wrote to provide the kind of documentation you're looking for. It seems a bit kludgy, but it works for me. It's not a simple as the other response, but it provides output that can be incorporated into other documentation.
Note - the documentation is out of date with respect to Union queries. The query I have to analyze Union queries seems to only pick up the 1st two things that go into the Union, so I changed this to a Make Table query, and manually edit the resulting table to add the missing relationships.
To use the queries:
Copy the table and all the queries into your database
Run the "Mapping Unions Make Table" query
Manually edit the Unions table if necessary
When you run any of the 3 main output queries, you are prompted for the Top object you want to analyze. Enter the name of a query or table to find all the dependencies for that object. The three main outputs are:
Mapping Summary - lists all of the objects that go into the top object and all of the objects that go into them, to a depth of about 10 (depth is controlled in the "Mapping all parents" query)
Mapping summary without duplicates
Mapping summary duplicates
I especially like the 2nd output - this is in a format that can be saved in Excel and input to Visio's Org Chart Wizard to get a simple graphical representation of the relationships. Then the 3rd output query can be used to manually add in the queries that go into more than one other query, which Visio's wizard cannot handle.
just facing a little problem right now.
I have a layout-table that contains one field pages. This should specify for which pages the layout should be applied.
The possible contents are "closed" ranges like '3-5' or open ranges like '3-*'. But it should also be possible to add single pages.
So is there a good way to accomplish a content like that
'3-5;11;15;17-*'
in a single field?
Or do you know better ways?
Is there a possibility to query this field like
SELECT * WHERE IN_RANGE(pages, '5') (Pseudo-Code)
I want to prevent creating a table page because it would contain nothing else and also don't want to do the validation in php.
I am happy to provide more information if necessary.
This is a tricky question i dont see "native" sql option for this.
My first idea was to store information about pages as varchar and implement method to tokenize that string so youll have values which you can then process by sql query.
I am not looking for actual code, more like a tutorial that I could reference and adjust for my own purposes or the name of a plugin that will do what I am trying to do. I have looked online and cannot seem to find what I am trying to achieve. I am probably just not searching for the right name.
I have a mysql database with several columns. I would like to make a search area on the left side of the screen next to the displayed database (the database is displayed with PHP) that would search the database based on the user's search criteria. I would like them to be able to search by name, Date of the week, and also have a keyword search.
The only way I can describe the look of the search area would be to have it look like Walmart's Refine Results (http://www.walmart.com/browse/Computers/Desktop-Computers/_/N-96fg?browsein=true&catNavId=3951&ic=48_0&ref=+428236).
As I said, I have looked online, but can't find anything. Hopefully someone can provide me with a point in the right direction.
Well, MySQL's LIKE operator will work for the "keyword" search. The reference manual can be found at http://dev.mysql.com/doc/refman/5.0/en/string-comparison-functions.html. When you say "name," is this something they type in, or will they select from a list of some sort? Same question goes for the date, I suppose.
Also, what language are you looking to code the app itself in?
AJAX can be used with PHP to create more user-friendly and interactive searches.
AJAX can be used for interactive communication with a database.
Results are shown as you type.
Results narrow as you continue typing.
If results become too narrow, remove characters to see a broader result.
You can use this instead of combobox when a user types a character in the input field some function is triggered by the "onkeyup" event:
like on this http://www.w3schools.com/php/php_ajax_livesearch.asp
And as u want to search data from database
u can refer following..
http://www.w3schools.com/php/php_ajax_database.asp
I think proper combination of both will help u to solve ur problem....
