Does DESC/DESCRIBE Have An Equivalent In Transact-SQL
May 7, 2008
Hi,
I have been training in SQL on MySQL, and now that I am on TSQL, I can't seem to find an equivalent to the command:
Code Snippet
DESC table_name;--OR
DESCRIBE table_name;
In MySQL, either command returns a list of the columns of the table, as well specifications about these columns (whether or not they can accept NULL values, their default values, etc.)
Hi All, Once again I find myself smacking my head into a wall (and it will probably be for naught). I'm trying to find a specific character in a string within a specific record. I've tried substring, but it's not quite getting me where I want to be. I even tried "nesting" the substring and got nowhere (but I could have had the syntax wrong when I nested it).
Here is a sample
Select substring(productimagefile, 20, 5) from my table
What I need is something like this:
Select substring(findoneof(productimagefile, _r, 1), 1, 5) from my table
Actually, on the start of the substring, I need it to be where it finds the _r, just not sure how to tell it that. The replace function is the closest I've seen to what I need, but I don't want to replace it with anything, I just need to find it in the string.
So, if anyone has any ideas, I'd be grateful (and my head would stop hurting....)
my query is that in my database i've a table say Tb1 and another table called Tb2.
in TB1 there is a field called companyID (the data is for e.g "001")
similarly in TB2 there is a filed called productID (the data is for example "01")
now how can i create a field in another table say TB3 with a field called UserID and the data should be like the companyID from TB1 + productID from Tb2. The data should come like this for example " 001-01 ".
I am more familiar with writing SQL for Oracle than MS SQL Server. Within Oracle there is a simple command, 'Describe', which actually shows the data types, and whether or not an attribute accepts NULLS.
MS SQL Server does appear to support such a command, however I am looking for a way to describe the attributes of tables nonetheless.
Hey guys, I have a view with dates (TheDate) meant to be arranged in descending order. When I 'Execute SQL' while in the view, the DESC order works just fine and shows up with the latest date first going down. However, once I 'OPEN VIEW' the order keeps defaulting to ASCending order.
How do I keep it in DESC order for viewing? Here's the statement:
SELECT TOP (100) PERCENT TheDate FROM dbo.MyDates ORDER BY TheDate DESC
In my SSIS package I am trying to connect to a database in Oracle 10.2.0.3 using an Oracle Provider for OLE DB.

Why this is not working for 10.2? The same package works fine for Oracle 8.1.7 THANKS FOR YOUR HELP!
In the followinf portion of my SQL Statement, I cannot figure out how to specify ASC or DESC for the OrderBy... If I Put OrderDate ASC after the THEN, I get an error and if I put @SortDir after the END I get an error... Can Anyone help with this? WHERE OrderID IN(SELECT OrderID FROM #rsltTable WHERE ID >= @l_FirstRecord AND ID <= @l_LastRecord)ORDER BYCASE @OrderByWHEN 'OrderDate ASC' THEN OrderDateWHEN 'OrderDate DESC' THEN OrderDateEND Thank You,Jason
hi, i have headers at the top of my list and would like for people to click the pubs link and it orders the pubs alphabetically descending and when they click again to ascend also to do this with towns and addresses and postcodes?!
Does anyone have a general rule or guide on when to use this SQL 2000 option when creating indexes? I was thinking generally on nonclustered indexes where the column would be unique and incremental and usually filtered on by range and often used in the order by clause. Such as columns of datetime or integers datatypes. Thanks.
I have a column name "DESC" in SQL Server table and I am getting an error when trying to insert data into this column. I cannot rename this column as it's not in my hand.
Please anybody reply me with good solution I am new to SQL.
I have a stored procedure in my SQL 2005 Server database named Foo that accepts two parameters, @paramA and @paramB.In my ASP.NET page, I have these:<asp:GridView id="gv" runat="server" AutoGenerateColumns="true" DataSourceID="DS" AllowSorting="true" DataKeyNames="ID"/><asp:SqlDataSource ID="DS" runat="server" ConnectionString="<%$ ConnectionStrings:CS1 %>" SelectCommand="Foo" SelectCommandType="StoredProcedure" OnSelecting="DS_Selecting"> <asp:Parameter Name="paramA" Type="String" /> <asp:Parameter Name="paramB" Type="String" /></asp:SqlDataSource>In my setup, paramA and paramB are set in DS_Selecting(), where I can access the Command.Parameters[] of DS.Now, here's the problem. As you can see, the GridView allows for sorting. When you click on a header title to sort, however, the GridView becomes empty. My question is, how can I get the GV sorted and in the correct direction (i.e. asc/desc)? My first step in my attempt was to add another parameter to the SqlDataSource and sotred procedure Foo (e.g. @SortByColumn), then changed Foo appropriately: ALTER PROCEDURE Foo @paramA nvarchar(64), @paramB nvarchar(64), @SortColumn nvarchar(16) = 'SearchCount' AS SELECT * FROM Searches ORDER BY CASE WHEN @SortColumn='SearchCount' THEN SearchCount WHEN @SortColumn='PartnerName' THEN PartnerName ELSE ID ENDThat works find and dandy. But wait--I want to get the correct ORDER BY direction too! So I add another parameter to the SqlDataSource and Foo (@SortDirection), then alter Foo: ... SELECT * From Searchces ORDER BY CASE /* Keep in mind that CASE short-circuits */ WHEN @SortColumn='SearchCount' AND @SortDirection='desc' SearchCount DESC WHEN @SortColumn='SearchCount' SearchCount WHEN @SortColumn='PartnerName' AND @SortDirection='desc' PartnerName DESC WHEN @SortColumn='PartnerName' PartnerName WHEN @SortColumn='ID' AND @SortDirection='desc' ID DESC ELSE ID END ...But including DESC or ASC after the column name to sort by causes SQL to error. What the heck can I do, besides convert all my stored procedures into in-line statements inside the ASP page, where I could then dynamically construct the appropriate SQL statement? I'm really at a loss on this one! Any help would be much appreciated!Am I missing a much simpler solution? I am making this too complicated?
The following statement seems to ignore my sort expression....how can I fix this? Select TB.* FROM TblBlogs TB JOIN (select top 20 blogId, count(*) cfrom tblCommentsgroup by blogIdorder by count(*) desc) T20 ON TB.BlogId = T20.BlogId
There is a index: CustomerInfo_1 with keys: customerId, EnteryDate DESC I could not find where the order of index key (i.e. whether the key is ascending or descending) is stored? I tried system tables such as sysindexes and sysindexkeys tables. But could not find it. Any help in this regard will be truly appreciated.

I have come across a problem executing a select with a multi-part where clause that only shows up if there are multiple indexes on the table. The situation using a simplified table is shown below
create table tblTest( utcTimestamp datetime NOT NULL, testType int NOT NULL)go
insert into tblTest (utcTimestamp, testType) VALUES('6/1/2003 0:0:0', 100)go
Now, without adding any indexes to the table, I can execute the following select and it works fine, returning the single row in 2003:
select * from tblTest where utcTimestamp < '1/1/2004 0:0:0' and utcTimestamp > '1/1/2003 0:0:0' and testType = 100go
Furthermore, if I introduce a single descending index on just the utcTimestamp:
CREATE INDEX IX_tblTest_Timestamp ON tblTest (utcTimestamp DESC)go
the search still works.
HOWEVER, if I now introduce another index:
CREATE INDEX IX_tblTest_EntryType_Timestamp ON tblTest ( testType, utcTimestamp DESC)go
the search does **not** return the row. However, if I change the where clause to remove the test of testType:
select * from tblTest where utcTimestamp < '1/1/2004 0:0:0' and utcTimestamp > '1/1/2003 0:0:0'go
it works.
Also, strangely, if I populate the table with a number of records with different dates and execute the following search:
select * from tblTest where utcTimestamp > '1/1/2004 0:0:0' and testType = 100go
I get records from **earlier** than 1/1/2004 (i.e. like the sense of the compare is wrong)
Finally, as I was writing this report, I discovered that all of these problems go away if the DESC is removed from the indexes - so that's my workaround, but it still looks like a bug.
I am using sql statement like SELECT CREATEDBY,FIRSTNAME,BUSINESS,NOTES,NOTESDATE FROM BUSINESS ORDER BY NOTESDATE DESC, CREATEDBY ASC But NotesDate is sorting descending order, but only sorting based on the date and month not on year Please help me
Identity(1,1) column ID is primary key and only clustered index key.
Rows will be inserted regularly into this table, hundreds per day.
Queries will be mostly selecting on the most recent records.
In a year, the row will have half a million records or so and only the most recent records will be used. There will be a forward-rolling hot spot, of most recent records.
Does the direction of the ID column in the clustered index make a difference?
I'm thinking no, because query plan will go to that leaf in an index seek regardless of whether it is old or new, "bottom" or "top" of index, especially if the query is very specific on the ID.
I am trying to order by the field and direction as provided by input parameters @COLTOSORTBY and @DIR while using a CTE and assigning Row_Number, but am running into syntax errors.
Say I have a table called myTable with columns col1,col2,col3,
Here's what I'm trying to do
with myCTE AS ( Select col1 ,col2 ,col3 ,row_number() over (order by case when(@DIR = 'ASC') then
case when @COLTOSORTBY='col1' then col1 asc when @COLTOSORTBY='col2' then col2 asc else col3 asc end else
case when @COLTOSORTBY='col1' then col1 desc when @COLTOSORTBY='col2' then col2 desc else col3 desc end end from myTable )
Please let me know what i can do with minimal code repetition and achive my goal of dynamically sorting column and direction. I do not want to use dynamic SQL under any circumstance.
I have a SSIS package that reads data from a dump table, runs a custom script that takes date data and converts it to the correct format or nulls and formats amt fields to currency, then inserts it to a new table. The new table redirects insert errors. This process worked fine until about 3 weeks ago. I am processing just under 6 million rows, with 460,000 or so insert errors that did give error column and code.
Now, I am getting 1.5 million errors. and nothing has changed, to my knowledge. I receive the following information.
Error Code -1071607685 Error Column 0 Error Desc No status is available.
The only thing I can find for the above error code is
DTS_E_OLEDBDESTINATIONADAPTERSTATIC_UNAVAILABLE
To add to the confusion, I can not see any errors in the data written to the error table. It appears that after a certain point is reached in the processing, everything, or most records, error out.
Table 1: AddressBook Fields --> User Name, Address, CountryCode
Table 2: Country Fields --> Country Code, Country Name
Step 1 : I have created a Cube with these two tables using SSAS.
Step 2 : I have created a report in SSRS showing Address list.
The Column in the report are User Name, Address, Country Name
But I have no idea, how to convert this Country Code to Country name.
I am generating the report using the Layout tab. ( Data | Layout | Preview ) Report1.rdl [Design]
Anyone help me to solve this issue. Because, in our project most of the transaction tables have Code and Code description in master table. I need to convert all code into corresponding description in all my reports.
I have looked around and found the equivalent for IIF (Access) to be aSELECT CASE in SQL. I have tried this with no success. I am also lookingfor the equivalent of MAX and have had no luck.
