MS SQL Server :: Dynamic SQL Reading Statements From Table

Returning And Reading Multiple Select Statements From One Stored Procedure

Dec 3, 2006

Hey Guys. I’m having a little trouble and was wondering if you could help me out. I’m trying to create a custom paging control, so I create a stored procedure that returns the appropriate records as well as the total amount of records. And that works fine. What I’m having problems with is reading the data from the second select statement within the code. Anyone have any idea on how to do this? Also.. how can I check how many tables were returned?
Here's my code. I'm trying to keep it very generic so I can send it any sql statement:public DataTable connect(string sql)
{
DataTable dt = new DataTable();

SqlConnection SqlCon = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["MyDB"].ToString());
SqlDataAdapter SqlCmd = new SqlDataAdapter(sql, SqlCon);
System.Data.DataSet ds = new System.Data.DataSet();
SqlCmd.Fill(ds);

dt = ds.Tables[0];

//Here's where I don't know how to access the second select statement

return dt;
} Here's my stored procedure:
ALTER PROCEDURE dbo.MyStoredProcedure
(
@Page int,
@AmountPerPage int,
@TotalRecords int output
)

AS

WITH MyTable AS
(

Select *, ROW_NUMBER() OVER(ORDER BY ID Desc) as RowNum
From Table
where Deleted <> 1
)

select * from MyTable
WHERE RowNum > (((@Page-1)*@AmountPerPage)) and RowNum < ((@Page*@AmountPerPage)+1);

Select @TotalRecords = COUNT(*)
from Table
where Deleted <> 1
RETURN

Thanks

Using DTS For Reading Dynamic .CSV Files From A Folder

Sep 20, 2006

Hi All,

I have a challenge i am trying to overcome, hopefully soneone would have come across this issue before..

I am creating a DTS package that will be scheduled to run at a certain time everyday. A source folder exists that get a set of new files everyday.The DTS Package will then read each file and copy the data into a load table in my database the challenge is this:

I am trying to load files from a source folder into my load table, Within each file, the entires are in a specific format using pipes to seperate the data that goes into which column e.g

example of a file entry:

column1 | column2 | column3

data1 | data2 | data3

data1 | data2 | data3

data1 | data2 | data3

And now i am using DTS to specify the file format and map the cloumns as apprporiate to my table...all this is well and good, but my problem is each file has a different name as well as being timestamped, now how do i use DTS to specify the source folder, open each file sequentially and read (or more appropriate, copy the entries into my table, inserting new data from each file into my load table as well as overwriting old data in the load table from the files in the folder ?) is there a way in specifying your source folder in DTS rather than specifying the file in the Menu options (in the transformation data task properties )given, and or do i need to write a script for this(reading the file?)

can someone please give me a solution and how to approach this?

thanks in advance

Dynamic SQL Statements In A Stored Procedure

Mar 18, 2004

Hi

I have a small problem writing a stored procedure in a SQL Server 2000 database.

I would like to generate som part of the SQL inside this stored procedure that is used in an IN expression of my WHERE clause. There is no problem for me to generate a string containing my expression, the problem is that SQL-Server don�t generate a resulting SQL-statement.

Example:

CREATE PROCEDURE spDynStatement
AS

DECLARE @sPartOfSQLStatement NVARCHAR(100)

-- Some T-SQL that generates the dynamic part of the SQL-statement
-- .
-- .
-- .

-- As substitute I insert the string expression
SET @sPartOfSQLStatement = '''1''' + ', ' + '''1.5'''

-- SELECT @sPartOfSQLStatement results in: '1' , '1.5'

SELECT * FROM BBNOrganization WHERE OrgStructureID IN( @sPartOfSQLStatement ) -- does not work

SELECT * FROM BBNOrganization WHERE OrgStructureID IN( '1', '1.5' ) -- works!!!
GO

Thankfull for ideas on how to solve my problem,

Peter

The Dynamic SQL Statements With Output Parameters

Nov 15, 2005

The dynamic SQL statements with output parameters, unfortunately, in the documentation are not described.
À) Simple example of the dynamic SQL statement with output parameters

-- dynamic SQL statements expects parameter of type 'ntext/nchar/nvarchar'.
declare @SQLString nvarchar(4000), @ParmDefinition nvarchar(4000)
-- the third parameter passed in the dynamic statement as by output, returns the length of
-- the hypotenuses of a right triangle, two first parameters are lengths of legs of a triangle
declare @nHypotenuse float
select @SQLString = 'select @nHypotenuse = sqrt(square(@nLeg1_of_a_triangle)+square(@nLeg2_of_a_triangle))',
@ParmDefinition = '@nLeg1_of_a_triangle float, @nLeg2_of_a_triangle float, @nHypotenuse float out'
-- we call the dynamic statement in such a way
exec sp_executesql @SQLString, @ParmDefinition, @nLeg1_of_a_triangle = 3.0, @nLeg2_of_a_triangle = 4.0, @nHypotenuse = @nHypotenuse out
-- or in such a way
exec sp_executesql @SQLString, @ParmDefinition, 3.0, 4.0, @nHypotenuse out
select @nHypotenuse -- Displays 5.0

B) Example of usage of the dynamic statement with output parameter and the function GETALLWORDS.
The following stored procedure get all words from a field of the type text or ntext, the word length should not exceed 4000 characters.

CREATE PROCEDURE SP_GETALLWORDSFROMTEXT
@TableName sysname, @FieldIdName sysname, @FieldIdValue sql_variant, @FieldTextName sysname, @cDelimiters nvarchar(256) = NULL
AS
-- this Stored procedure inserts the words from a text field into the table.
-- WORDNUM int – Sequence number of a word
-- WORD nvarchar(4000) – the word
-- STARTOFWORD int – position in the text field, with which the word starts
-- LENGTHOFWORD smallint – length of the word
-- Parameters
-- @TableName name of the table with the text or ntext field
-- @FieldIdName name of Id field
-- @FieldIdValue value of Id field
-- @FieldTextName name of field text or ntext
-- @cDelimiters Specifies one or more optional characters used to separate words in the text field
begin
set nocount on

declare @k int, @wordcount int, @nBegSubString int, @nEndSubString int, @nEndString int, @divisor tinyint, @flag bit, @RetTable bit,

select @TableName = object_name(object_id(lower(ltrim(rtrim(@TableName))))), @FieldIdName = lower(ltrim(rtrim(@FieldIdName))), @FieldTextName = lower(ltrim(rtrim(@FieldTextName))),
@cDelimiters = isnull(@cDelimiters, nchar(32)+nchar(9)+nchar(10)+nchar(13)), -- if no break string is specified, the function uses spaces, tabs, carriage return and line feed to delimit words.

select @RetTable = 1
end
-- we use the dynamic SQL statement to receive the exact name of text field
-- as we can write names of fields by a call of the given stored procedure in the arbitrary register

Reading And Writing To Same Table

Feb 16, 2008

I need to select all the records in a table, loop through them one by one, calculating some new field data, and then write the new data back to the same table. Here is the basic structure of what I've come up with:<CODE>SqlCmd = SqlConn.CreateCommandSqlStatement = "SELECT ProductID, Name FROM tblProducts"SqlCmd.CommandText = SqlStatementSqlRdr = SqlCmd.ExecuteReaderIf SqlRdr.HasRows Then While SqlRdr.Read If SqlRdr.FieldCount > 0 Then ... SqlWriteCmd = SqlConn.CreateCommand SqlStatement = "UPDATE tblProducts SET Name = '" & NewName & "' WHERE ProductID = " & CStr(ProductID) SqlWriteCmd.CommandText = SqlStatement SqlWriteCmd.ExecuteNonQuery() SqlWriteCmd = Nothing End If End WhileEnd IfSqlRdr.Close()SqlCmd = Nothing </CODE>I get an error that tells me to close out the Reader before trying to execute the write query. But I can't close it out for the loop to work properly. So I assume that there must be another way to do this simple task, but I'm so new to all of this that I need some help! Thanks!

Reading From One Table And Then Storing It Into Another Table

Feb 13, 2007

I want to (and succeeded) read information from one table in my database ([services] in this case) and display them in a table with an additional column with a textbox so that I can enter volumes in it. So far so good, this works fine. But I now want to store all the volumes together with the ID's in a seperate table ([service_volume]) by clicking the Submit button.
Does anyone know how to achieve this?

T-SQL (SS2K8) :: Reading A Control Table - Avoid Using A Cursor

Jan 21, 2015

I am trying to think of a way to read a control table, build the SQL statement for each line, and then execute them all, without using a cursor.

To make it simple... control table would look like this:

CREATE TABLE [dbo].[Control_Table](
[Server_Name] [varchar](50) NOT NULL,
[Database_Name] [varchar](255) NOT NULL,
CONSTRAINT [PK_Control_Table] PRIMARY KEY CLUSTERED

[Code] ....

So if we then load:

insert into zt_Planning_Models_Plant_Include_Control_Table
values ('r2d2','planing1'), ('r2d2','planing7'), ('deathstar','planing3')

Then you would build a SQL script that would end up looking like the following (note all the columns are the same):

insert into master_models
Select * from r2d2.planning1.dbo.models
insert into master_models
select * from r2d2.planning7.dbo.models
insert into master_models
Select * from deathstar.planning3.dbo.models

How To Get Statistics On DML Statements Per Table

Aug 18, 2006

Can I get statistics on which type of DML statements (e.g. insert, delete, update) that are executed by users on a table without creating triggers? I want to be able to show the number of executed statements per statement type. I have tried the 2005 Profiler but it outputs the entire batch statement which makes it a bit more difficult to create statistics.

Transactions And Create Table Statements

Jan 27, 2007

I have some problems getting my SSIS package to run in a transaction, I wonder if anyone can assist.

What I want to do is run one package, which consists of a

- 1) create staging table SQL statement

- 2) read (all) from Access MDB to staging

- 3) copy (only new) from staging table to real table

- 4) drop the staging table

I changed the package to "require" a transactions, and left all containers in it to "supported" (default, I think). I left all the transaction type to default "serializeable".

The package does not work, since the table I created on step one is not "seen" when step 2 wants to insert into it. If I set the package transaction back to "supported" (default) the package works, but an error on step 2 or 3 will not rollback changes and not remove the staging tables...

So, my question really is: How do I make step 1 results visible to step 2 in the same transaction? Or do I need to take a completly different approach for this?

Stupid question I think, but I seem to not be able to find the right way to handle this situation...

Thanks for reading!

How To Make Sure No Other Table Writes Happen Between 2 SQL Statements ?

Nov 25, 2007

Ok, here is my situation.....
When someone navigates to a user's profile page on my site, I present them with a slideshow of the user's photos using the AJAX slideshow extender. I obtain the querystring value in the URL (to determine which user's page I'm on) and feed that into a webservice via a context value where an array of photos is created for the slideshow. Now, in order to create the array's size, I do a COUNT of all of that specific user's photos. Then, I run another SQL statement to obtain the path of those photos in the file system. However, during the time of that first SQL query's execution (the COUNT statement) to the time of the second SQL query (getting the paths of the photos), the owner of that profile may upload or delete a photo from his profile. I understand this would be a very rare occurrence since SQL statements 1 and 2 will be executed within milliseconds of each other, but it is still possible I suppose. When this happens, when I try to populate the array, either the array will be too small or too large. I'm using SqlDataReader for this as it seems to be less memory and resource intensive than datasets, but I could be wrong since I'm a relative beginner and newbie. This is what I have in my vb file for the webservice.....Public Function GetSlides(ByVal contextKey As String) As AjaxControlToolkit.Slide()     Dim dbConnection As New SqlConnection("string for the data source, etc.")     Try          dbConnection.Open()          Dim memberId = CInt(contextKey)          Dim photoCountLookupCmd As New SqlCommand _               ("SELECT COUNT(*) FROM Photo WHERE memberId = " & memberId, dbConnection)          Dim thisReader As SqlDataReader = photoCountLookupCmd.ExecuteReader()          Dim photoCount As Integer          While (thisReader.Read())               photoCount = thisReader.GetInt32(0)          End While          thisReader.Close()          Dim MySlides(photoCount - 1) As AjaxControlToolkit.Slide          Dim photoLookupCmd As New SqlCommand _               ("SELECT fullPath FROM Photo WHERE memberId = " & memberId, dbConnection)          thisReader = photoLookupCmd.ExecuteReader()
          Dim i As Integer          For i = 0 To 2               thisReader.Read()               Dim photoUrl As String = thisReader.GetString(0)               MySlides(i) = New AjaxControlToolkit.Slide(photoUrl, "", "")          Next i          thisReader.Close()          Return MySlides     Catch ex As SqlException     Finally          dbConnection.Close()
     End Try
End FunctionI'm trying to use the most efficient method to interact with the database since I don't have unlimited hardware and there may be moderate traffic on the site. Is SqlDataReader the way to go or do I use something else? If I do use SqlDataReader, can someone show me how I can run those 2 SQL statements in best practice? Would I have to somehow lock writing to that table when I start the first SQL statement, then release the lock after I execute the second SQL statement? What's the best practice in this kind of scenario.
Thanks in advance.

DataSet With Multiple SELECT Statements To The Same Table

Apr 29, 2008

Hi,
OK, trying to return the results from two SQL statements into a DataSet using SqlDataAdapter. The SELECT statements query the same table but are looking for different records based on the date that the records were inserted - the 1st query looks for records fro the current month and the 2nd one looks at the same records but for the previous month. The goal is to be able to do some math within a repeater and get the difference between the two records.
Sounds easy enough and it has worked for me in different variations of the same idea but not this time - here's the code:
Protected Sub buildPartsReport(ByVal varHC) objConn.Open() sSQL = "SELECT ap.id,item_model,item_sn,aircraft_id,item_loc=item_type+ ' on ' +(SELECT tnum FROM T_Aircraft WHERE id=aircraft_id),apt.tot_time As endTimes,apt.tot_cycles as endCycles FROM T_Aircraft_Parts ap, T_Aircraft_Parts_Totals apt WHERE ap.id=apt.part_id AND report_date= '" & rD & "' AND item_type LIKE 'engine%';SELECT ap.id,apt.part_id,apt.tot_time as startTimes,apt.tot_cycles as startCycles FROM T_Aircraft_Parts ap, T_Aircraft_Parts_Totals apt WHERE ap.id=apt.part_id AND report_date= '" & oldRD & "' AND item_type LIKE 'engine%'" Dim objCommand As New SqlDataAdapter(sSQL, objConn) DS = New DataSet() objCommand.Fill(DS) Repeater1.DataSource = DS Repeater1.DataBind() DS.Dispose() objCommand.Dispose() objConn.Close() End Sub
Sorry if it wrapped a bit. The "rD" and "oldRD" are the variables for the date ranges (currently set to static numbers for testing). I'm getting the following error when I run this on an ASP.Net page:
System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'startTimes'.
The code works fine when run via the Query Tool on the SQL server (SQL 2005 Std) though it produces two distinct "tables" which I'm guessing is the problem. I've tried variations on the code including creating a 2nd dataset and then attempting a merge (no joy) and I've tried the ".TableName" route but it complains about trying to add the tablename twice.
Thoughts? I need to get this to work - it is part of a reporting component for an application that I'm developing and I'm stuck. Thanks as always...

Running UPDATE Statements In Parallel On The Same Table

Feb 23, 2007

Hi all,

Does an UPDATE statment lock the entire table or just the rows that will be affected by the UPDATE?

I ask because -

Can I run UPDATE statements in parallel on the same table on the same column. The need for doing this is because the table is a large fact table. I plan to execute the same UPDATE statements on different time sections of the data to expedite the processing.

If the UPDATE statment lock the entire table then I cannot run an UPDATE in parallel. If the UPDATE statement just locks the rows that will be affected then maybe I can because rows affected will be different for each UPDATE.

Let me know.

Thanks,

Vivek

SQL 2012 :: Take Rows From A Table And Display INSERT STATEMENTS

Oct 13, 2015

There is a valuable script out there that will take the rows from a table and display INSERT STATEMENTS.

Good thing is this script converts the data to HEXADECIMAL ( or some other ) and we don't have to worry about dealing with apostrophies embedded in varchar fields.

SQL 2012 :: Automatically Create Insert Statements For Table Data

Jun 10, 2014

How to create insert statements of the data from a table for top 'n' rows. I know we can create using generate scripts wizard, but we can't customize the number of rows. In my scenario i got a database with 10 tables where every table got millions of records, but the requirement is to sample out only top 10000 records from each table.

I am planning to generate table CREATE statements from GENERATE Scripts wizard and add this INSERT STATEMENT at the bottom.

EX : INSERT [dbo].[table] ([SERIALID], [BATCHID] VALUES (126751, '9100278GC4PM1', )

Transact SQL :: Method To Generate Insert Statements For Data In A Table

May 30, 2013

I have a database which will be generated via script. However there are some tables with default data that need to exist on the database.I was wondering if there could be a program that could generate inserts statments for the data in a table.I know about the import / export program that comes with SQL but it doesnt have an interface that lets you copy the insert script and values into an SQL file (or does it?)

Export Table Data Into A Series Of Insert Statements (or Alternative)

Jan 29, 2008

Hi all,

I have a table which I would like to export to a series of insert statements (in a file maybe). Is this possible somehow?

Alternatively, I could use an existing xml document which contains table metadata (table name, column names,types etc) to transfer data from these particular columns to another database replica.

Thanks,
Yannis

SQL Server 2012 :: Find Subset Of Records From A Table - Multiple Except Statements

May 13, 2015

I created a CTE which finds a subset of records from a table

I then ran a SELECT statement against the same table as

SELECT * FROM TABLE
EXCEPT (SELECT * FROM CTE)

Is it possible to add another EXCEPT statement after the CTE EXCEPT statement to cover a condition not incorporated in the CTE definition?
