Effect Of A SELECT Stored Procedure On Tables Or Database
Jul 25, 2007
Hi all,
I have a few stored procedures which all perfom SELECT queries on a table in the database. Do these kind of stored procedures affect any other processes or procedures working on that table. I am talking about locks, blocks etc.
For example, the database has a table which gets updated periodically by some process which I don't know. Now I wrote some stored procedures just to do the SQL SELECT with some conditions in WHERE clause. Is there any possibility that my stored procedure failed and the because of this, the process that runs on the table was not executed?
SELECT @stateabr=state_abr FROM Public.dbo.state WHERE state_id=@state_id
INSERT INTO registration_form VALUES(@firstname,@lastname,@job_title,@manager,@cost_center,@address,@city,@stateabr,@zip,@email,@phone,@roommate,@arrival,@departure,@special_needs)
IF @@rowcount>0 SET @result=1 GO
This is the specific line where I'm trying to access a different database:
SELECT @stateabr=state_abr FROM Public.dbo.state WHERE state_id=@state_id
I want my application to create a new database/tables when run for thefirst time. I have created a stored procedure to create the newdatabase named "budget". When I run the stored procedure, it createsthe budget database but the tables are created in the "master"database. Please help.
I executed them and got the following results in SSMSE: TopSixAnalytes Unit AnalyteName 1 222.10 ug/Kg Acetone 2 220.30 ug/Kg Acetone 3 211.90 ug/Kg Acetone 4 140.30 ug/L Acetone 5 120.70 ug/L Acetone 6 90.70 ug/L Acetone ///////////////////////////////////////////////////////////////////////////////////////////// Now, I try to use this Stored Procedure in my ADO.NET-VB 2005 Express programming: //////////////////--spTopSixAnalytes.vb--///////////
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim sqlConnection As SqlConnection = New SqlConnection("Data Source = .SQLEXPRESS; Integrated Security = SSPI; Initial Catalog = ssmsExpressDB;")
Dim sqlDataAdapter As SqlDataAdapter = New SqlDataAdaptor("[spTopSixAnalytes]", sqlConnection)
'Pass the name of the DataSet through the overloaded contructor
'of the DataSet class.
Dim dataSet As DataSet ("ssmsExpressDB")
sqlConnection.Open()
sqlDataAdapter.Fill(DataSet)
sqlConnection.Close()
End Sub
End Class ///////////////////////////////////////////////////////////////////////////////////////////
I executed the above code and I got the following 4 errors: Error #1: Type 'SqlConnection' is not defined (in Form1.vb) Error #2: Type 'SqlDataAdapter' is not defined (in Form1.vb) Error #3: Array bounds cannot appear in type specifiers (in Form1.vb) Error #4: 'DataSet' is not a type and cannot be used as an expression (in Form1)
Please help and advise.
Thanks in advance, Scott Chang
More Information for you to know: I have the "ssmsExpressDB" database in the Database Expolorer of VB 2005 Express. But I do not know how to get the SqlConnection and the SqlDataAdapter into the Form1. I do not know how to get the Fill Method implemented properly. I try to learn "Working with SELECT Statement in a Stored Procedure" for printing the 6 rows that are selected - they are not parameterized.
Is it possible to execute a stored procedure in one database, which thenitself executes a stored procedure from another database? We have decide tosplit our data into a tree structure (DB1) and data blobs (DB2) (we areusing MSDE and we have a 2gb limit with each DB so we've done it this wayfor that reason). I would like to, say, execute a stored procedure in DB1,passing in the data blob and other details, DB1 will create a tree node inDB1 and then add the blob record to DB2. DB1 will wrap in a transaction ofcourse, as will DB2 when it adds the blob. Is this possible?
Hello all, thanks in advance for any advice here. My question is, what's the effect of the Enterprise Manager > Tasks > Shrink Database function? It seems to reduce the used space on the device. Testing it on some dev machines, I've seem to have gotten back as much as 20g of space. I know it should grow back to that, but the time it took was minimal, and it didn't seem to affect my developers. They tend to add alot and delete alot during testing. What negative effects of running this should I look out for? Will it affect the DB long term? Is is preferable to schedule once a month or so? Is this done on Production DB's? Thanks for any guidence on the usage of this.
I had run a stored procedure in my server that update statistics against all user defined tables in my database (MSSQL 7.0).
Since then I am getting errors in my ASP application where I am reffering to adovbs.inc.
Here is an example of errors I get.
Microsoft VBScript runtime error '800a0411'
Name redefined: 'adOpenForwardOnly'
/Essai/adovbs.inc, line 14
Below is the stored procedure I have run against the database.
Can anybody help tank you guys.
CREATE PROCEDURE update_all_stats AS /* This PROCEDURE will run UPDATE STATISTICS against ALL user-defined tables within this database. */ DECLARE @tablename varchar(30) DECLARE @tablename_header varchar(75) DECLARE tnames_cursor CURSOR FOR SELECT name FROM sysobjects WHERE type = 'U' OPEN tnames_cursor FETCH NEXT FROM tnames_cursor INTO @tablename WHILE (@@fetch_status <> -1)
BEGIN IF (@@fetch_status <> -2)
BEGIN SELECT @tablename_header = "Updating " + RTRIM(UPPER(@tablename)) PRINT @tablename_header EXEC ("UPDATE STATISTICS " + @tablename ) END FETCH NEXT FROM tnames_cursor INTO @tablename END PRINT " " PRINT " " SELECT @tablename_header = "************* NO MORE TABLES" + " *************" PRINT @tablename_header PRINT " " PRINT "Statistics have been updated FOR ALL tables." DEALLOCATE tnames_cursor
I have a stored procedure that calls a msdb stored procedure internally. I granted the login execute rights on the outer sproc but it still vomits when it tries to execute the inner. Says I don't have the privileges, which makes sense.
How can I grant permissions to a login to execute msdb.dbo.sp_update_schedule()? Or is there a way I can impersonate the sysadmin user for the call by using Execute As sysadmin some how?
How do I search for and print all stored procedure names in a particular database? I can use the following query to search and print out all table names in a database. I just need to figure out how to modify the code below to search for stored procedure names. Can anyone help me out? SELECT TABLE_SCHEMA + '.' + TABLE_NAME FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE = 'BASE TABLE'
Hi, I want to set the max and min of a query to the variable @Value1 and @Value2. However, when I do the following, both @Value1 and @Value2 pointed to the latest data. Do I have to use a subquery to do that or is that possible to do it directly? DECLARE @Value1 DECIMAL(7,2) DECLARE @Value2 DECIMAL(7,2) SELECT TOP 20 @Value1=MIN(Value1), @Value2=MAX(Value2)FROM OrdersGROUP BY OrderID, Date
I have the stored procedure snipet below and it does not return anything. What am I doing wrong here? I works ok if I need all the records for the dataset and don't use the WHERE and LIKE. CREATE PROCEDURE dbo.search @Field VARCHAR (20), @KeyWord VARCHAR (200), @errCode INT OUTPUT ASBEGIN DECLARE @guid uniqueidentifier DECLARE @subject NVARCHAR SELECT @guid = guid, @subject = subjectFROM myTable WHERE @Field LIKE @KeyWord SELECT guid, subjectFROM myTable WHERE @Field LIKE @KeyWord
In Informix you can use a stored procedure as part of a SELECT statement:
SELECT ord_num, ord_date, ship_date, business_day_diff(ord_date, ship_date) FROM order_table
business_day_diff is a stored procedure that uses a custom calendar to compute business days. In fact, Informix stored procedures can return any data type. Apparently SQL Server stored procedures cannot be used in a SELECT like this.
Does anyone know of a straightforward way to accomplish the same purpose?
How do you use the value of one select statement within another select statement inside the same stored proc?
Here is my scenario: I need a row id from one select statement to make another select statement. I figured instead of making two calls from within my code I could just call one stored procedure which would have to be faster!
I have written plenty of select statement sp's but this is the first time I ever needed to do something like this.
How could I use SELECT TOP in stored procedure For ex I want convert this line to Stored procedure
"Select Top "&intArticles&" * From tblArticles WHERE published = 1 ORDER BY Adate DESC, Atime DESC;"
I dont want use ROWCOUNT because its not working good it will not show some data of some fields for example if I have Subject and Body fields, in results it does not show body content, and it will show just subject :confused:
this is my current code
CREATE PROCEDURE [dbo].[SP_Articles] ( @Articles int ) AS SET ROWCOUNT @Articles SELECT tblArticles.* FROM tblArticles WHERE published = 1 ORDER BY Adate DESC; SET ROWCOUNT 0 GO
Hey all! I have a quick question. Is it possible do formulate a select query where one of the tables is a recordset returned from a stored procedure? If so, what's the syntax?
In other words, if I have a stored proc whose last command is:
selectt.[Region_Code], t.[Country_Code], sum([Total]) as [Total] from#tmp t group by[Region_Code], [Country_Code] order by[Region_Code], [Country_Code]
Then can I somehow get a handle on that cursor and join it to another table etc? Thanks!
I have a stored procedure that has many select statements in it. I want to call and execute the procedure in my c# code and put data returned by each select statement into separate grids. I could just write the select into the c# code and then execute as a dataset making that dataset the datasource for whatever grid but that defeats the purpose of stored procedures. Can I capture the data returned by each select in the stored procedure and have it put into a grid when the c# code is ran.
HelloI have many different tables, that most have the same structure.. they allhave some primary key, some fields and mylinkid ... so what I want to makeis to create a stored procedure, where I can pass the table-name, primarykey, and the new mylinkid, what should happen is, that the procedure copiesthe entrie, where i passed the id, to a new row and the mylink-id should getthe new value...example:mytable 1id=1 (primary key autoincrement)mylinkid=233field1=asdffield2=blablai call my procedure like: duplicate_entry 'mytable',1,4the result should then beid=2 (primary key/autincrement)mylinkid=4field1=asdffield2=blablaI was thinking to make a Stored Procedure, that copies the entier row with aselect * into mytable (SELECT * from mytable where id=1) and afterwards iupdate the mylinkid ..... but there i have problem with the primary key.The other solution that will work, but I won't like is to get with thesp_fields all fields from that specific table, build the select into withthe correct fields without the id-field... that should work, but was askingmyself if there is somethign better...Has someone a good idea for that?Thanks
I have code simililar to the following in a stored procedure:
CREATE PROCEDURE GetGroupMembers ( @GroupID INT )
AS SELECT TMembers.MemberID, VCurrentMemberGroups.GroupID, THonorsMembers.HonorID FROM THonorsMembers LEFT OUTER JOIN TMembers ON THonorsMembers.MemberID= TMembers.MemberID LEFT OUTER JOIN VCurrentMemberGroups ON TMembers.MemberID= VCurrentMemberGroups.MemberID WHERE (VCurrentMemberGroups.GroupID = @intGroupID) AND TMembers.DeleteDate IS NULL ORDER BY TMembers.MemberID
RETURN GO
When I call this stored procedure in Query Analyzer, it takes two minutes to execute. The web pages that rely on it time out before that. If I copy just the select statement and substitute the group I'm working with for @GroupID, it takes less than a second for the statement to run and display results.
Can anyone tell me why a select statement called through a stored procedure would take minutes longer than one ran from Query Analyzer? I have many other stored procedures that are just select statements like this with a variable or three and they have no problems completing execution in a timely manner.
I have a complex stored procedure that returns one or more nvarchar values given a syntax similar to this:
sp_MyProcedure 'Param1', 'Param2'
My issue is that the end goal is to get these values into a SQL query that I can call directly from something like Excel (no VBA or anything can be used). So far, I have come up with this:
INSERT INTO [#tmpTable] EXEC sp_MyProcedure 'Param1', 'Param2'
SELECT * FROM AnotherTable
WHERE (AnotherTable.ID IN (select * from [#tmpTable])) AND (AnotherTable.Year>2007)
drop table [#tmpTable] ********************************************************************************************************
That works, but it is incredibly sloppy once I have need to make 4 or 5 temp tables like that and then select from all of them inside the same query. So does anyone have any suggestions? Can I use a function to help out?
I am currently building an electricity quoting facility on my website. I am trying to insert the data which the user enters into 3 linked tables within my database. My stored procedure therefore, includes 3 inserts, and uses the @@Identity, to retrieve the primary keys from the first 2 inserts and put it as a foreign key into the other table. When the user comes to the quoting page, they enter their contact details which goes into a client_details table, then they enter the supply details for their electric meter these get inserted into the meter table which is linked to client_details. The supply details which the users enters are used to calculate a price. The calculated price, then gets put into a quote table which is linked to the meter table. This all seems to work fine with my stored procedure. However I want to be able to allow a user to enter more than one meter supply details and insert this into the meter table, with the same client_id for the foreign key. This will also generate another quote to insert into the quoting table. However I do not know how to get this to work. Should I be looking at using Sessions and putting a SessionParameter on the client_id for the inserts for these additional meters??
Hello, Is it possible to search in two tables, let's say table # 1 in specific field e.g. (age). If that field is empty then retrieve the data from table #1, if not retrieve the data from table # 2. Is it possible to do it by using SQL Stored Procedure?? Thank you
ok, ill lay it out like this, and try not to be too confusing.

Hi,If one uses a temporary table/ table variable within a storedprocedure, will it use the compiled plan each time the stored procedureis executed or will it recompile for each execution?Thanks in advance,Thyagu
So I have simply procedure: Hmmm ... tak sobie myślę i ...
Czy dałoby radę zrobić procedurę składową taką, że pobiera ona to ID w ten sposob co napisalem kilka postow wyzej (select ID as UID from aspnet_users WHERE UserID=@UserID) i nastepnie wynik tego selecta jest wstawiany w odpowiednie miejsca dalszej procedury ?[Code SQL]ALTER procedure AddTopic @user_id int, @topic_katId int, @topic_title nvarchar(256), @post_content nvarchar(max)as insert into [forum_topics] (topic_title, topic_userId,topic_katId) values (@topic_title, @user_id, @topic_katId) insert into [forum_posts] (topic_id, user_id,post_content) values (scope_identity(), @user_id, @post_content)Return And I want to make something more. What I mean - in space of red "@user_id" I want something diffrent. I make in aspnet_Users table new column uID which is incrementing (1,1). In this way I have short integer User ID (not heavy GUID, but simply int 1,2,3 ...). I want to take out this uID by this :SELECT uID from aspnet_Users WHERE UserId=@UserId.I don't know how can I put this select to the stored procedure above. So I can have a string (?) or something in space of "@user_id" - I mean the result of this select query will be "@user_id". Can anyone help me ? I tried lots of ways but nothing works.
