Because all that data has to come across the network to you, increasing network load needlessly.
On the other hand, if you really want all the columns, then using * is OK.
|
|
|
|
|
If you explicitly specify the columns in a SELECT statement, they are guaranteed to be returned in the order you specify. Consequently, you may safely identify the columns as theReader(0), theReader(1), etc. rather than having to have the system look up the column names on every theReader("customerName") access. If, for whatever reason, the expected columns don't exist, it's probably better to have the problem caught in the SELECT statement than to throw an exception when the non-existent data is accessed.
If your code is genuinely interested in getting all the columns that are or ever will be in the database, including any that may be added in future, then SELECT * is appropriate. This may be the case, for example, in a database viewer (though unless a naming convention is used to indicate fields that should be regarded as confidential, such an approach could be dangerous even there). If you're only interested in a few fields, even if the fields of interest are at present the only ones in the database, you should specify explicitly the fields of interest.

Cross posting is considered rude...
In any case, what has this got to do with Oracle?
|
|
|
|
|
just hit the return key on the typewriter instead of space key.
|
|
|
|
|
Another option is to insert enough spaces if word wrapping is on...

Hi all,
I wrote a StoredProcedure which returns a dataset.
But when i drag that SP into .dbml file, the return type of SP is becomes int, not ISingleResultType<>. I dont know reason for this.
When i call that SP i got Error / Return vale 0
Plz Help me.
Here my SP:
ALTER PROCEDURE [dbo].[USP_GetAdNames](
@user varchar(50),
@specialization smallint = null,
@country smallint = null,
@state tinyint = null,
@city varchar(50)= null,
@from datetime = null,
@to datetime = null
)
AS
CREATE TABLE #TEMPADS
(
int_ID int,
str_Name varchar(50)
)
DECLARE @query nvarchar(1000)
BEGIN
SET @query = N'INSERT INTO #TEMPADS SELECT transAds.int_AdID,transAds.str_Name
FROM TRANS_ADS AS transAds
WHERE transAds.str_UserID = '''+@user+''''
if (@specialization != null OR @specialization != 0)
SET @query = @query + ' AND tansAds.smallint_Specialization = '+cast(@specialization as varchar(10))
if (@country != null OR @country != 0)
SET @query = @query + ' AND transAds.smallint_CountryCode = '+cast(@country as varchar(10))
if(@state != null OR @state != 0)
SET @query = @query + ' AND transAds.tinyint_FocusState = '+cast(@state as varchar(10))
if(Ltrim(Rtrim(@city)) != '' OR Ltrim(Rtrim(@city)) != null)
SET @query = @query + ' AND transAds.str_FocusCity = '''+@city +''''
if(@from IS NOT NULL)
SET @query = @query + ' AND transAds.dt_Modifiedon >='''+convert(varchar(25),@from,101)+''''
if(@to IS NOT NULL)
SET @query = @query + ' AND transAds.dt_Modifiedon <='''+convert(varchar(25),@to,101)+''''
print @query
EXECUTE sp_sqlexec @query
SELECT int_ID,str_Name FROM #TEMPADS
END
///// When i execute in SQl Management Studio iam getting records as dataset. But not in my program.
I am calling that sp like this:
var query = from temp in DataContext1.USP_GetAdNames("kvs",null,null,null,null,null,null) select temp;
.....................................................
I also tried creating a partial class in DataContextMapping.Designer.cs file but no use.
Please suggest me, what went wrong in my SP.

Try using table variables instead of temporary tables since the result set of a stored procedure with temporary tables can not be inferred.

Hi,
Take the SELECT statement to a separate statement and take the return values (for example username or COUNT) to a local variable and then test the variable value in IF statement.

Given that he has a syntax error (code won't even compile) how will checking the logic of the stored procedure help?
|
|
|
|
|
That's true, didn't notice the missing AS keyword  .
|
|
|
|
|
You are missing the keyword AS
CREATE PROCEDURE Name
@parameters parameter_types
AS
BEGIN
-- Code goes here.
END
|
|

Thank you guys,
But how can i forget such small thing.
Thanks a lot

It's pretty obvious that password hashes for SQL Server 8.0 and 9.0 are different. So when migrating a server from SQL server 2000 to SQL Server 2005, everyone's password pretty much gets jacked.
Is there a way to login to a SQL Server 2005 instance using SQL Server 200 credentials?
I've tried specifying the provider and driver in my connection string for my ADO objects but get an error thrown back at me saying that the "provider" keyword is not recognized.
|
|
|
|
|
So here's the story. I was wrong about the hashes.
But, 2005 uses case sensitive passwords by default. So when our vendor's application converts all passwords to upper before connecting, of course it'll do the same when it creates the users.
So I have the misfortune of being an idiot and writing supplementary applications for badly designed software. Yay for me, and all I have to do now is edit a few libraries.

Hello

You can use Visual Studio for debugging. Select the procedure from Server Explorer and "Step Into Stored Procedure"

iam passing a string example "hi this is john" then how i can i check whether the string john is there in the string or not in given string .
|
|
|
|

Just a sample how can you implement in your real data.
DECLARE @val AS VARCHAR(255)<br />
SET @val='hi this is john'<br />
<br />
IF(SELECT CHARINDEX('john',@val))>0<br />
BEGIN<br />
PRINT 'exists' <br />
END<br />
ELSE<br />
PRINT 'doesnt exists'
