My problem is that Intellisense does not provide complete auto suggest for the columns that I have in my tables .
Here is an example:
As you can see on SSMS it does give me auto suggest for my tables, but does not for columns. I have read couple articles about solving some Intellisense issues, but nothing helped. Here is things I tried described in this article: http://www.mssqltips.com/sqlservertip/2591/troubleshooting-intellisense-in-sql-server-management-studio-2012/
Any suggestions would be greatly appreciated, thank you for your time!
IntelliSense can't predict which table you're going to select from, and will wait until you have at least one table in the FROM clause, and probably only until you specify an alias. before populating the columns in the case of a join or other multi-table query.
There's a good reason for this. Imagine if you have CustomerID or InvoiceID in 20 different tables in your database. Should it list this 20 times? Which one should you pick? Do you really want all the columns in your entire database in a drop-down list? In a lot of scenarios this will be a very long list. And not pretty either, in things like SharePoint, NAV Dynamics, etc.
If you're not happy with the way the native IntelliSense works, there are 3rd party tools that might do what you want, but I'm not sure what you want will actually help you work any better.
First, that's because at the time of the screenshot SSMS does not know from what object you are selecting. In other words, it cannot guess what columns you're interested in when there is not a from clause in your select statement. If you try to type in the columns in the following select statement...
select from dbo.Invoices
you will see that SSMS will start to pick up your columns because you have already specified a from clause, so SSMS knows how to suggest you column names...because there is a table specified in the from clause
This is mainly occurs when you add any table in the Database OR Add any Column in the Table.
This is the known issue of the SQL Server 2012. You need to refresh the Cache for that.
You can achieve using 2 ways..
1) You can Refresh the Local Cache of the IntelliSense.
Open New Query window and Navigate to following menu.
Edit > IntelliSense > Refresh Local Cache
Shortcut key for this is (Ctrl + Shift + R)
2) ReConnect Your Database.

I've been searching the internet for hours trying to figure out if the following is even possible:
To choose the AS400 query records directly from Excel.
I haven't found any solution or description of how this could be achieved, which makes me guess that it's simply not possible. However, I haven't seen anyone confirm that it is impossible.
So my question is: Is this possible? And if it is, could you point me in the right direction in order for me to start learning how to do it?
I know its possible to run a query from Excel, and then adding parameters via SQL statements, but in my case, this presents several problems that could be avoided by choosing the records before the query is executed.
Example:
I have a query with a column (lets call it ColVal) that can hold the values 1 and/or 2. In the AS400 program under the menu "Work with queries" and then "Choose records" I can specify which records the query should contain when it has run based on the value in ColVal. This means i can get three different situations (A, B and C) when i run the query:
A) The query only contains records where the value in ColVal is 1
B) The query only contains records where the value in ColVal is 2
C) The query contains records where the value in ColVal is either 1 or 2
The goal is to be able to choose which situation I want from Excel in order to circumvent opening and using the AS400 program.
However, using situation C and then editing the query in Excel with an SQL statement to mimic situation A or B is not an option, as this means the query still contains undesired records.
This whole thing boils down to the following: Is it even possible to run the query from Excel essentially changing the data it contains and not just outputting it to excel? If this is possible, is it then possible to pass a parameter to the AS400 system and use it to create situation A, B or C?
I hope this example makes sense.
Edit - New example
Say i have different customers A and B. I can open the AS400 program and run a query in which i have specified that I only want data on customer A. I can then open Excel and use filters (as Hambone described) on the query to determine which records I want to output. However, if I want to work with data from customer B, I have to open the AS400 again and run the query with different parameters. I would like to be able to "change" my dataset from customer A to B from Excel, without having to include both in my recordset and then filter out one of them.
I imagined this is doable if you could pass a parameter to the AS400. The AS400 then runs the query using this parameter as the criteria for which records should be stored in the query. This means that if the parameter is Customer B, then there is no way to acces data from customer A, without running the query through AS400 again.
Any ideas are greatly appreciated :)
Follow up to my comment, here is a quick primer on how to run an ODBC query directly in MS Excel using Microsoft Query. This is very different than Power Query, which you referenced, in that MS Query is standard with Excel -- it's not a plug-in. This is relevant because it means everyone has it. If you are deploying a solution to others, that's an important consideration.
To start an MS Query in Excel, go to the data tab, select "From Other Sources" -> "Microsoft Query."
A list of your ODBC connections will come up. Pick the one that you want and select "OK."
It may or may not ask you for a login (depending on which ODBC connection you use and how its configured).
The next part is important. MS Query is going to try to have you use its builder to create the query. If you have the SQL, skip this part. It's horrible. Click "Cancel" on the query wizard, and then click the "SQL" button to enter your own SQL. If you can, make sure the result set is small (like use where 1 = 2 in the query).
When MS Query returns results, click the button next to the SQL Button to have it return the results to the spreadsheet. It looks like a little door.
From here, any time you want to refresh the query, you can simply right-click the data table in Excel and select "refresh." Alternatively you can go to the data tab on the ribbon and select "Refresh."
By the way if you have linked pivot tables and charts, the "Refresh All" option will refresh those as well, in the correct order.
To edit your query at any time, right-click on the table in Excel, go to Table-External Data Properties:
Then Click on the Connection Properties icon (highlighted below)
Click on the second tab (Definition) and edit the SQL Directly.
Parameters can be declared simply by inserting a bare "?" in place of your literal.
In other words, if your query looks like this:
select *
from users
where user_id = 'hambone'
Just change it to:
select *
from users
where user_id = ?
Excel will prompt you for a user id before it runs the query. From here, you also have the option of putting the parameter value in a cell within the spreadsheet and having the query read it from there. You'll see these when you right-click the table and go to the "Parameters" menu option.
Let me know if this helps or is unclear.
-- EDIT 7/23/2018 --
To follow up on your latest edit, it is possible to handle the scenario you describe, where you want to be able to filter on a value, or if none is given, then not have a filter. You see this a lot when you present multiple filter options to the user and you want a blank to mean "no filter," which is obviously counter to the way SQL works.
However, you can hack SQL to still make it work:
select * from activities
where
(activity = ? or ? is null) and
(energy = ? or ? is null)
In this example you have to declare four parameters instead of two, two for each.
You might also have to play with datatypes, depending on the RDBMS (for example for numerics you might have to say ? = 0 instead of ? is null or even ? = '' for text).
Here is a working example where a single filter was applied on the query above and you can clearly see the second one did not have an impact.
Yes it's possible. You need to use an ODBC driver to connect to the AS400 and retrieve the data. The driver and documentation are Here
Using JetBrains' DataGrip 2017.3.4 I have it linked to a Sybase TSQL database. All I wish to do is find a table in it so that I can find the structure.
I have selected all nodes and opened them 3 times - once for the dbo, once for the tables and procedures and once for the list of tables and procedures - and can now select the top line and "simply type the table I am a looking for", or so I am told.
If looking for tb_AllSaints, this does not seem to be a problem. However, when looking for tb_ZZTop, the table tb_MaxZZTop keeps "helpfully" popping up first and there doesn't seems to be a way to find the "next" table in the list. If it is a particularly long list, scrolling through by hand is murder.
The alternative, Ctrl-N, will enable me to select data from any table but I cannot get the table structure at all.
Help...
There are two solutions.
When using Speed Search with tb_ZZTop, press Down arrow - it will navigate you to the next match. There are some issues there, not always works: https://youtrack.jetbrains.com/issue/DBE-5927
If in your case it also doesn't work, please, comment with the screenshot there.
When using Ctrl+N navigation (it can be handy if the tree is not expanded or you have no idea where your table is), click on DDL button in the data editor. There you will see the DDL, where structure information is stored.
I was hoping someone out there may have experienced this before.
I have a database that (as far as I'm aware) is in perfect working order. I have no problems with it whatsoever. I'm trying to add a column to some of the tables but when I save the changes I get the following message
This error message is then stuck in a loop and the only thing I can do is kill the SQL Management Studio process.
The database exists, the table exists, I can run any query I want against it, I just can't make any changes to it.
The steps I'm taking are:
Right click table
Select "design"
Right click "add new column" in designer
Fill in the details as normal
Click Save
Anyone know how I can resolve this?
Thanks.
It's telling you that you haven't specified the name of the table. The name of the table should be between the two single quotes.
Without knowing how you're doing this it's hard to tell more, but the first two possibilities off the top of my head are:
If you're looping through tables in code to do something, you may be hitting a record with no table name.
If it's pure SQL, perhaps an error in your syntax
This is with respect to search of a text in a table
Table_Name:
Details
Columns:
Fname,Mname,Lname,NName
This table contains nearly one lakh records
We are using Oracle forms for some querying option
The user input one name the form searches the table for the name and based on the name either(Fname/Mname/Lname/NName) in which column its is present further actions are proceeeded.
The search is taking a long time since we have huge amount of data present in the table.
I tried with Functional indexes for the table but t did not work its also taking more time
Later i tried with something like this
concatenated all the names into one name and put it into a cursor.
Using the cursor output i tried with Instring but it is hanging
I also tried with searching for building a dynamic cursor but it did not work.
My database is Oracle
Can u help me to out to find an effective solution or please help me if i have missed something.
Thanks
First of all, 1 lakh (100,000) records is not in itself a large table.
The problem I can see is the query appears to be doing an OR against the Fname/Mname/Lname/NName columns.
This means the query will be doing at least one full-table scan to obtain the results.
You may wish to use debug to obtain the query it is firing against the database and attempt to tune this at the SQL prompt using auto trace.
You may need to clarify if the search is also doing something like a LIKE against these columns rather than an EQUALS. As a LIKE will impact the query further and affect indexes.
Certainly the use of INSTR will disable indexes on your searched column.
It is not clear if what your block is based on ie. table, view, query, procedure
You may want to try using the hint on the block properties of the form FIRST_ROWS.
I made a GUI for generation of SQL, something much similar to MS Access Visual Query Designer, the purpose was to let our Customer Service team make their own reports. But even after designing the whole thing and I can see that they are unsure on how to proceed for generating a new report.
SQL is much intuitive for me after long experience, but things like grouping, aggregate functions, various date/string functions are not easy for a non programmer.
How can I make it easier for a non programmer to build the SQL using a GUI?
Maybe you can apply a simplifying transcription of the SQL. Think something like https://ifttt.com/wtf. This in combination with the visual part might make it easier to understand what's happening.
Please follw up :
1) combo box for selecting database
2) combo box for selecting table for selected database
3) One Grid is display columns for selecting table.
4) user select,update column display name, order of display, aggregate of column option, group on column option.
5) finally display result in grid as per selection of column setting.
