Cannot Run Dynamic Sql Using 'USE DB_Name' Statement

Feb 4, 2002

For whatever reason, the following when executed does not take the context of the supplied Database name. Any ideas as to why? More importantly is there a work around. I am trying to create a database level batch job.

declare @sql nvarchar(100)
set @sql = 'USE Northwind'
print @sql
EXEC sp_executesql @sql


Thanks,

Mark

SQL Server 2012 :: Create Dynamic Update Statement Based On Return Values In Select Statement

Jan 9, 2015

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".

Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

Dynamic SQL Statement

Apr 14, 2008

 I am trying to write a dynamic sql insert statement in c#, but given this is my first run at creating sql statements dynamically I am having issues.  My reason for creating the sql statement dynamically is because I do not want to insert any items that are null.  Will I have to have a separate string for each section of the statement?  For example:sql1 = "Insert Into Table [test]";sql += "(Column1, Column2, Column3," ;sql2 = "Values" ;sql2 += "(field1, field2, field3";  and then a third section if I were to use parameters.  My thinking here is how do you append to a string in numerous locations?  I will populate the sql strings first with those columns and fields that I know will not be null, and then use if statements to add to each sql string if the field in question != null.  in other words, little help.

How Do You Build A Dynamic WHERE Statement?

Mar 9, 2006

I have 5 drop down lists and 1 text box, and I need to build the WHERE portion of my SELECT statment (stored procedure). the drop down lists are named client, ptype, apptdate, inspdate, state, and the textbox is named text. they all need to be this=something AND that=another AND...AND text LIKE mytext.
How would I go about building this efficiently?
Would I Declare a bit value in the sp called WhereSet = 0
IF @client IS NOT NULL     IF @WhereSet = 0          SET @Where = 'WHERE ClientID=@client'          SET @SetWhere = 1    ELSE          SET @Where = @Where + ' AND CleintID=@client'    .    .    ....
Or would this be a lot easier using adhoc SQL instead of a Stored Procedure?
(note: I am using a SQL DataSource)
Please help, I am going bald from pulling my hair our...

Dynamic Statement Needed?

Apr 23, 2014

I have a stored procedure that populates a table. I want to query the table using column names as variables, however the data is in decimal format so I am getting errors converting varchar to numeric. My table consists of columns labeled D1, D2, etc. for every possible day of any month, DOW1, DOW2, etc. for every day of the week. I also have values labeled midDpct and midDOWpct. My query is as follows:

select *
from Table
where D10 > midDaypct * 2 and DOW6 > 0
union
select *
from Table
where DOW6 >midDOWpct * 2 and D10 > 0

We are targeting a specific day of the month and a specific day of week, day 10 and day of week 6 in this example. I want to make these variables so we can easily change out the target day and dow.

Using A Dynamic Top Statement With A Cursor

Help please,Have a situation when converting from Oracle SP's to SQL SP's. The oldoracle cursor was roughly as followsCURSOR cur_rsStock ISselect*from(select StockRowId, CategoryIdfromSTOCKDISPOSABLEwhereSTOCKDEFID=numDefIdORDER BYSTOCKROWID)whereROWNUM <= numQuantity;The closest I can get in MS SQL is as follows :declare cur_rsStockCURSOR forselect top @numQuantityStockRowId, CategoryIdfromSTOCKDISPOSABLEwhereSTOCKDEFID=numDefIdORDER BYSTOCKROWIDBut, SQL doesn't allow variables next to top. I know I can assign the wholeselect statement to a string and use exec to exec the string to get arecordset but how can I point a cursor to receive its output?i.e.set @strSQl = select top ' + @numQuantity + ' StockRowId, CategoryId.......exec @strSQLbut how do I dodeclare cur_rsStockset cur_rsStock = ( exec @strSQL)Flapper

Dynamic Select/Update Statement Possible?

Dec 3, 2004

Would it be possible to retrieve a "dynamically" named field from a table by using an input parameter?

For example, if a table has fields named Semester1, Semester2, Semester3, Semester4, and I was lazy and only wanted to create one stored procedure for all semesters could I do the following...

ALTER PROCEDURE u_sp_x
@semester int
AS
Select Semester@semester
From ThisTable

Just curious.

Thanks,

Dynamic Statement In Variable - Parseerror

May 8, 2006

I am trying to use this statement in a variable, including another variable:

"SELECT * FROM my_table WHERE CAST([timestamp] AS INT) > " + @[User::LastTimestamp]

But the variable value insists on giving me this error:

The expression for variable "VariableName" failed evaluation. There was an error in the expression.

I cast the columntype "timestamp" to int, and the variable "LastTimestamp is stored as int32, and has a default value of 0. I simply can't grasp what it is I am missing.

Is it because the expression is part string and part integer? If so, how is that avoided?

Thanks in advance

SQL Statement For Querying Data With Dynamic Fields

Sep 19, 2006

I am working on a project in which a customer wants to be able to list and search their inventory and display the items in a table/grid on a web page.Each item in their inventory has a set of properties - for example, manufacturer, price, serial number, name, etc.  The complicated part is that they want an admin to be able to modify/add/delete the set of properties.  So for example, they could add the attribute "size."   Given that, I think what is needed is 3 tables - one to store the set of properties schema, one for the items, and one to store the actual properties for each item.  I know i COULD use alter table statements to add and delete columns, but that doesn't seem like the "right" solution.I would like to be able to write a query such that each row returns the item and all its properties - then i can easily bind to a datagrid.  However, what would the query be to do this?  I also need to be able to allow the customer to query for items with certain properties - i imagine the sql for that to be similar to this:SELECT * FROM items d WHERE d.Id IN(SELECT a.ItemId FROM attributes a WHERE a.Name = "Manufacturer" AND a.Value = "Samsung") AND d.Id IN(SELECT a.ItemId FROM attributes a WHERE a.Name = "SerialNumber" AND a.Value = "3223")

Spooky Semi-dynamic Sql Update Statement

Nov 9, 2006

Hi,
I rewrote my working Sql statement to prevent Sql Injections. I copied some code I used in another project but this time I can't get it to work, possibly because it's an update statement and not an Insert one, which I used before.
Sorry for the boring question, but does anyone have a clue what's wrong with the syntax?
Here's the original code (I changed the parameter names for clarity and security):
    Dim conn As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString)    Dim strSQL As String = "Update MyTable Set " & typ & num & " = '" & pname & "' WHERE personID = " & fid    Dim cmd As SqlCommand = New SqlCommand(strSQL, conn)
Here's the code from codebehind:
    Dim conn As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString)    Dim strSQL As String = "Update MyTable Set (" & typ & num & ") Values (@" & typ & num & ") WHERE personID = " & fid    Dim cmd As New SqlCommand(strSQL, conn)    With cmd.Parameters       .Add(New SqlParameter("@" & typ & num, pname))    End With    TestLabel.Text = strSQL & "        " & pname    cmd.Connection.Open()    cmd.ExecuteNonQuery()    cmd.Connection.Close()   
Here's my test message; first the sql, then the new string to be inserted:
Update MyTable Set (picturename) Values (@pname) WHERE personID = 2       2_adin.jpg  
Here's my error code:
Line 1: Incorrect syntax near '('. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Line 1: Incorrect syntax near '('.
Source Error:
Line 489:            TestLabel.Text = strSQL & "  " & pnameLine 490:            cmd.Connection.Open()Line 491:            cmd.ExecuteNonQuery()Line 492:            cmd.Connection.Close()Line 493:        End If 
I could understand it if I'd get an error in VWD Express for using dynamic variables, but they work correctly in the text message so I'm clueless. Any help is deeply appreciated!

Building A Dynamic Sql Statement Into Stored Procedure

Apr 19, 2008

Hi i have a page whereby the user can make a search based on three things, they are a textbox(userName), dropdownlist(subcategoryID), and region (regionID). The user does not have to select all three, he or she can enter a name into the textbox alone and make the search or enter a name into the textbox and select a dropdownlist value, my question is how can i build this procedure, this is what another user suggested but i am having trouble;
ALTER PROCEDURE [dbo].[stream_UserFind]

@userName varchar(100),
@subCategoryID INT,
@regionID INT
)AS
declare @StaticStr nvarchar(5000)set @StaticStr = 'SELECT DISTINCT SubCategories.subCategoryID, SubCategories.subCategoryName,Users.userName ,UserSubCategories.userIDFROM Users INNER JOIN UserSubCategories ON Users.userID= UserSubCategories.userIDINNER JOINSubCategories ON UserSubCategories.subCategoryID = SubCategories.subCategoryID WHERE UserName like @UserName'
if(@subCategoryID <> 0) set @StaticStr = @StaticStr + ' and SubCategories.subCategoryID  = @subCategoryID 'if(@regionID <> 0) set @StaticStr = @StaticStr + ' and SubCategories.RegionId  = @regionID '

Dynamic Column Names In Select Statement

Oct 13, 2001

I have a quick question on SQL Server. Lets say I have table Order which has column names OrderId, CustomerName, OrderDate and NumberofItems. To select the OrderID values from the table I say
Select OrderId from Order.
But in the select if I want the column name to be variable how do I do it. I tried the following code through a stored procedure.

declare @order_id nvarchar(10)
select @order_id = 'OrderID'
SELECT @order_id from Order.

The code above gave me the string "OrderID" as many times as there were rows in the table but I could never get the actuall values in the OrderId column. Can you please send me some ideas or code where I can get values from the column names and at the same time change the column name dynamically.

Dynamic CREATE TABLE Or SELECT INTO Statement

Jul 27, 2004

In SQL Server you can do a SELECT INTO to create a new table, much like CREAT TABLE AS in Oracle. I'm putting together a dynamic script that will create a table with the number of columns being the dynamic part of my script. Got any suggestions that come to mind?

Example:

I need to count the number of weeks between two dates, my columns in the table need to be at least one for every week returned in my query.

I'm thinking of getting a count of the number of weeks then building my column string comma separated then do my CREATE TABLE statement rather then the SELECT INTO... But I'm not sure I'll be able to do that using a variable that holds the string of column names. I'm guess the only way I can do this is via either VBScript or VB rather then from within the database.

BTW - this would be a stored procedure...

Any suggestions would be greatly appreciated.

T-SQL (SS2K8) :: Generate Dynamic Update Statement

Aug 14, 2014

I'm trying to generate an update statement based off select statement results. A very basic example,

SELECT ListID FROM DListing WHERE Status = 2Results return 3 rows.
1234
2345
3456

How can I take those results and turn them into WHERE criteria for UPDATE statement?

Generated UPDATE statement should look like this.

UPDATE DListing SET Status = 1 WHERE ListID IN (1234,2345,3456)

I have started by creating a temp table to hold my SELECT results, but I don't know how to get those results into format for IN condition. Right now I get 3 UPDATE statements with 1 ListID in each IN condition.

CREATE TABLE #TempStatusUpdate(ListID INT)
INSERT INTO #TempStatusUpdate
SELECT ListID FROM DListing WHERE Status = 2
SELECT 'UPDATE DListing SET Status = 1 WHERE ListID IN (' + CONVERT(VARCHAR(30),ListID) + ') AND Status = 2'
DROP TABLE #TempStatusUpdate

Dynamic CASE Statement Based On List Of Dates

Oct 5, 2007

I have the following table of data.  I need to take a date from a large table and do the following case:CASEWhen date < date(0)     Then '0'When date between date(0) and date(1)      Then '1'When date between date(1) and date(2)     Then '2'When date >= date(3)      Then '3'What I need is to be able to read all the dates the the Date table, sort then chronologically, and build the dynamic CASE statement so that the first When statement is < Date(0) and the last When statement is >= Date(Last)I hope I am making sense.  Dates will be added to the table about once a year or so and I don't want to keep going back into the sql function and rewrite it with the latest date.  Any ideas how to manipulate these dates into a case statement?  Don't worry about the second table below.  I just wanted you to see why I need to return an int from the Case function.thanksMilton

T-SQL (SS2K8) :: Dynamic Column Names For Insert Statement?

I would like to provide the names of columns in an insert statement from a schema table, so that when running through a number of Bus Rule checks I can reference the schema table and only maintain the columns in the schema table rather than maintain named columns in multiple insert statements. So my query for one check looks like below. I'm using dynamic sql to execute the insert statement. My question is, is there a better way or different way to do this without using dynamic sql? Ie, Is there a way that I can use the columns parameter like this instead?

Insert
('+@columns+',KickoutID) Values('+@columns+',1);

Dynamic code:

Declare @columns as nvarchar(max);
Declare @InvSQL as nvarchar(max);
SELECT @columns =
STUFF ((
SELECT ', [' + name + ']'
FROM syscolumns WHERE id = OBJECT_ID('dbo.table_pvt')

[Code] ....

Dynamic Select Statement Using Parameterized SqlCommand Or Multiple Possible .CommandTexts

Jul 30, 2007

I'm trying to create an interface for filtering profiles from an SQLServer 2005 database using an html form. The form allows filtering based on a minimum level required in between one and four different columns. The first (and only mandatory) column to be filtered on has its name hard-coded into the base query. In trying to get the other three possible criteria to work, I've taken several approaches, all of which failed.The other three potential criteria are selected from a drop down menu on the form and ideally these choices are passed into a query to be used as column names. My first attempt looked like this:    query = "SELECT * FROM profiles_tbl WHERE (EngSkill >= @english)"    ....    if ReqSkill1 <> "" then                level1 = Convert.ToInt32(Request.form("minskilllvl1"))                query = query & pickclmleft & ReqSkill1 & pickclmright1                cmd.Parameters.Add("@ReqSkill1", SqlDBtype.text)                cmd.Parameters("@ReqSkill1").value = ReqSkill1                cmd.Parameters.Add("@level1", SqlDBtype.int)                cmd.Parameters("@level1").value = level1    end if   above If statement was repeated for 2nd and 3rd optionsSecond approach was to remove all parameters from sections of the query that were appended onto the original statement. This involved lots of strings containing AND clauses with hard-coded column names which were appended on when the corresponding option was selected in the form. Code looked like this:     query = "SELECT * FROM profiles_tbl WHERE (EngSkill >= @english)"     ASPqry = " AND (ASPlevel >= "    try             con = new SqlConnection()            con.ConnectionString = “**************string was correct****************â€?                        cmd = new SqlCommand()            cmd.Parameters.Add("@english", SqlDBtype.int)            cmd.Parameters("@english").value = english                                    if ReqSkill1 <> "" then                if ReqSkill1 = "ASPlevel" then                    query = query + " AND (ASPlevel >= "                    level1 = Convert.ToInt32(Request.form("minskilllvl1"))                    if level1 = 0 then                        query = query + "0)"                    end if                    if level1 = 1 then                        query = query + "1)"                    end if                    if level1 = 2 then                        query = query + "2)"                    end if                    if level1 = 3 then                        query = query + "3)"                    end if                end if            end ifFinally when this too failed, I created four entirely separate queries, detected how many criteria were used, and used the appropriate query, passing necessary skill level in as a parameter. I'll provide code if needed here. Queries were written as strings and then used to set the CommandText property for an SqlCommand variable. I think it's important to note that in all cases the most basic version of the query worked. In the first, if only the first criteria was used the statement executed fine. Same in the second. In the third, whatever query could be assigned first (even though only one could be assigned because of logical structure of if statements) worked and none of the others would. This last case was tested even with completely hard-coded queries that SQL Server 2005 validated as correct and would run. Any help is greatly appreciated. Will post as much code as people want/need, and if I can get any one of these methods working I'll be thrilled. I have no need for all three. A.S. Moser

SQL Server 2012 :: Convert Hardcoded SP Into Dynamic Merge Statement

Feb 13, 2015

I am working on to convert my static Store procedure to Dynamic.

I have created a Store procedure with Merge statement which is inserting new record and updating existing record.

This SP I will use in SSIS Insted of Data Flow Task I will run in Execute SQL Task.

Now my biggest problem is I dont know how to convert static code toi dynamic

Below is my Store procedure code.

As you can see my Source Query

I have a filemaster table as shown below which consist of Input filename,Source table ,Destination table and BBX expression.

Input_FilenameSourceTableName DestinationTableName BBxKeyDerExpr
CCTFB ImportBBxCctfb ArchiveBBxCctfb SUBSTRING(Col001,1,6)
CEMXR ImportBBxCemxr ArchiveBBxCemxr SUBSTRING(Col001,1,10)

In my source query I want to change the value of Source table ,Destination table and BBX expression dynamically on the basis of input file.

Purpose of making dynamic is that I have created separate sp for all the input, my clients want to have sungle dynamic sp which will execute on the basis of input file.this input file name I wil get fromm variable which i have created in SSIS Package.

Lets consider @File_name is the variable in package which store the file name

if file name is CCTFB then my query should take the Source table ,Destination table and BBX expression value from file master table.

Like that I have 100 of source query and evry query have diffrent number of columns. How can I change the column number in uodate and insert statement dynamically on run time.

CAST(SUBSTRING(Col001,1,6) + SUBSTRING(Col002,1,10) AS varchar(100)) :-It creates a key for comparing, this value i can take it from filemaster
HASHBYTES('MD5', CAST(CHECKSUM(Col001, Col002,Col003,Col004) AS varchar(max))) -here numberv of column need to be changed .
(SUBSTRING(SOURCE.Col001,1,6) + SUBSTRING(SOURCE.Col002,1,10)) this condition also i can take it from file master.

[Code] ....

I am able to get inserted and updated rowcount, but not able to get the matching records count.

Need Info About Dynamic Reporting (Read Problem Statement, Inside)

Jun 21, 2007

Hi All!

I have a specific requirement.

I have to generate a report on the fly.
The display fields, parameters and sort conditions would be user specified at run time in a ASP.NET web form. There will be a superset of the display, filter and sort fields out of which the user cans select one or more.

From the web form, i am taking these three parts as three strings and sending them as parameters to a Stored Procedure. The Stored Procedure will read each string, and identify what are the individual fields and generates the result accordingly.

So here my requirement is that Reporting Services must read the Stored Procedure, create a dataset and even create the User Interface all at run-time as we do not know what fields are displayed at design time. The Headers for each field come from the Stored Procedure. I have to show the report based on what are the fields in the Stored procedure at that instance of time.

I hope i have explained very clearly.

I would be grateful for your contributions.

Thanks
