I'm wondering if there's a way to pass a variable to assigning a decimal datatype;
declare @intPrecision int
set @intPrecision = 3
declare @decVariable decimal(38, @intPrecision)
I've basically been given the task by my mentor to create a script to round a decimal to a given number of decimal places.
ie; 1234.56789; 2 dp => 1234.57 and not 1234.57000
Any advice would be great.
Is there a way to write such a query where we can declare the variable dynamically ? Currently I am using the query as shown below :
declare @pYear_Internal as NVarchar(100)
set @pYear_Internal = [D FISCALPERIOD].[FP CODE].[FP CODE]
WITH
MEMBER MEASURES.[REVENUE] AS [Measures].[TOTAL REVENUE]
SET LAST5YEARS AS STRTOMEMBER(@pYear_Internal).Lag(4) : STRTOMEMBER(@pYear_Internal)
[code]....
While executing the above query, getting the error - Query (1, 9) Parser: The syntax for '@pYear_Internal' is incorrect. Â It looks like it doesn't recognize DECLARE keyword as it does with SQL queries. Â I just want a query that runs directly against the server.Â

I am reviewing some code we have inherited (riddled with multiple nested cursors) and in the process of re-writing some of the code. I came across this and it has me puzzled.
As I understand it, if you declare a variable and then try to re-declare a variable of the same name an error is generated. If I do this inside a While loop this does not seem to be the case. What ever is assigned is kept and just added to (in the case of a table variable)
I understand things are in scope for the batch currently running but I would expect an error to return (example 1 and 2)
--Table var declaration in loop

DECLARE find_dates CURSOR FOR

I have the following lines embedded in a stored procedure
---

----
select @querystr = "select @lkinpos = pos_lkin_pos from "+@database+" where pos_clnt_id = "+str(@clntid)+" and pos_isin ="+"'"+ @isinno+"'"
print @querystr
exec(@querystr)
---
---

When i execute the above stored procedure, it returns an error as follows:
Server: Msg 137, Level 15, State 1, Line 1
Must declare the variable '@lkinpos'.
When i see the print @querystr statement, it returns the query str as follows:
select @lkinpos = pos_lkin_pos from nsdldpm..pos_mstr where pos_clnt_id = 10000045 and pos_isin ='ine227a01011'
This when executed independently, gives me the required output.
Can anybody solve this for me?

I've been curious why some variables don't need to be declared with a value type in a stored procedure. Please see the example below in the bolded area.

Hey,
I am filling a temp table with various float variables and I need to format one particular column to 2 decimal places.
Does anyone know the correct syntax to do this, and should it be done before filling the temp table or when I select what I needs from the temp table?

In the old DTS package, we can use Active-x script to set the variable value:

Hi guys
I have a trigger which retrieves database names from a table.
I need to use this retrieved database name in another sql insert statement as a variable
e.g. set @mydbname = Select .... from.. (to get the database name)
then..
insert into @mydbname.dbo.emplTable
At the moment it reads @mydbname as the string "@mydbname" not the value the variable holds
I need the database name as a variable because i have to write to the correct database (there are 15)

I've a roblem with table variables in dynamic sql context.
If i use it with normal sql there is of course no problem.
Simplified it looks like this:

DECLARE @TestTable as TABLE(MyBigInt bigint NOT NULL, Myint int NOT NULL);
INSERT @TestTable SELECT 4711,10
SELECT* FROM @TestTable

If i do the same thing in dynamic sql, i get errors.

Is there any better method to compare read these 52 table variables?

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?

Ok, so I have this stored procedure that Inserts a record and I need to return the ID inserted to pass to another procedure. I ended up having to use sp_executesql because I need to dynamically add the schema to the table. The issue that I am having is that the variable that I try to pass to the other procedure always ends up null, but it shows the correct output.

Hi I'm new to MS SQL and trying to write a very small dynamic stored procedure which is giving me a headache.
What I have is:
CREATE PROCEDURE busy_report
@TableName varchar(255),
@reporteddate datetime=NULL
AS
if @reporteddate is null
select @reporteddate = CURRENT_TIMESTAMP
-- Create a variable @SQLStatement
DECLARE @SQLStatement varchar(255)
SET DATEFORMAT dmy
-- Enter the dynamic SQL statement into the
-- variable @SQLStatement
SELECT @SQLStatement = "SELECT vendor, reporteddate, count(vendor) FROM " +
@TableName + "WHERE reporteddate = ' "
+ @reporteddate + " '"
-- Execute the SQL statement
EXEC(@SQLStatement)
GO
The error I keep getting is:
Server: Msg 8114, Level 16, State 4, Procedure busy_report, Line 0
Error converting data type varchar to datetime.
Any ideas appreciated.
(Edit:)
I've also tried it this way:
CREATE PROCEDURE UK_busy_report
@TableName varchar(255),
@reporteddate datetime=NULL
AS
-- Create a variable @SQLStatement
DECLARE @SQLStatement varchar(255)
SELECT @reporteddate=CONVERT(datetime, @reporteddate)
IF @@ERROR <> 0 BEGIN
/* Do some error processing */
PRINT 'Error Occured' END
ELSE
-- Enter the dynamic SQL statement into the
-- variable @SQLStatement
SELECT @SQLStatement = "SELECT vendor, reporteddate, count(vendor) FROM " +
@TableName + "WHERE reporteddate = ' "
+ @reporteddate + " '"
-- Execute the SQL statement
EXEC(@SQLStatement)
GO
Which gives me the same error!
.logic.
Not wishing to derail the other recent thread on loading a local variable, I've posted this query (hee,hee,hee...I kill me) on a separate thread...though I think I am trying to do something similar...that is to build a dynamic select statement, but return a count of the rows it finds/doesn't find to a local variable...using the (amazingly timely) responses above, I tried this:
Note that the local variables @TargetDate and @TLevel are necessary because they are being passed into the procedure as variables....
DECLARE @SQLCmd varchar(256)
DECLARE @TargetDate smalldatetime
DECLARE @TLevel int
DECLARE @n int
SET @TargetDate = '2004-05-24'
SET @TLevel = 1
SET @SQLCmd = 'SELECT @n = count(*) FROM EventLog WHERE ((CONVERT(varchar(10), [Date], 101) = ''' +
CONVERT(varchar(10), @TargetDate, 101) + ''') AND (MsgLevel = ' +
CONVERT(varchar(3), @TLevel) + '))'
exec (@SQLCmd)
if @n > 0
print 'yep'
else print 'nope'
and, it's TRYING to work...but apparently the local variable @n is not recognized in the execution of the dynamic statement, as this is the output:
Server: Msg 137, Level 15, State 1, Line 1
Must declare the variable '@n'.
nope
Thoughts?
HiI'm grateful for any light you can shed on this!!I've to admit, it's an unusual design but I've multiple contact tables namede.g. i2b_ash_contact or i2b_ted_contact.'i2b_' and '_contact' are static but the middle part is dynamic.Storing all contacts in one table with an identifier of e.g. 'ash' or 'ted'for each record is not possible.Returning the value from the dynamic Query is no problem but I don't knowhow to assign it to a variable.When I try doing this it either runs into problems with evaluating thevariables or doesn't retuen anything at all e.g. if I say at the end 'Print@AddressID'. The variable remains empty.How can I do something like:DECLARE@AddressID int,@ProgClient (varchar(10),@Table varchar(10)Note: @Prog is a string e.g. 'ash' or 'ted'SET @Table = 'i2b_ + @ProgClient + '_contactSET @AddressID = (SELECT AddressID FROM @Table WHERE ContactID = @ContactID)
View 2 Replies View RelatedI am trying to use the idea as mentioned by Jamie at:
http://blogs.conchango.com/jamiethomson/archive/2005/12/09/2480.aspx
which is to build dynamic SQL using a variable evaluated as an expression.
Set Expression="SELECT * FROM MyTable WHERE MyColumn = " + @[VariableContainingFilterValue]
Everything works fine. The entire package works.
My next step is to log the variable so that I know, after package execution, exactly what SQL statement the package is executing.
I tried to do it by a couple of ways in a Script task:
1) Dts.Events.FireInformation(0, String.Empty, String.Format("SQL: {0}", Dts.Variables("SourceSQL").Expression), String.Empty, 0, False)
Gives me just an expression without actually evaluating it
2) Dts.Events.FireInformation(0, String.Empty, String.Format("SQL: {0}", Dts.Variables("SourceSQL").Value), String.Empty, 0, False)
Produces an error:
The expression for variable €œSourceSQL€? failed evaluation. There was an error in the expression.
