Hello guys!
I am looking for the best DataType that makes it possible to store strings of variable length (from 15 to 300 caracters, rarely longer).
Thanks a lot for any help !
Regards,
Fabianus
my favorit hoster is ASPnix : www.aspnix.com !
My app is in a shared hosting environment. They use SQL Server authentication and I'm not wild about storing user ids and passwords in web.config. What's the best practice for storing this connection string information?
Thanks
Good afternoon,
I have an issue with an ssis variable datatype.
The scenario is as follows:
I have a stored procedure:
PROCEDURE [dbo].[sp_newTransaction]
@sourceSystem varchar(50),
@txOut NUMERIC(18,0) OUTPUT
AS
insert into scn_transaction (sourceSystemName) values(@sourceSystem);
SELECT @txOut = @@identity
Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).
I execute the stored proc with the following sql with an OLE DB connection manager:
exec sp_newTransaction ?, ?
The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:
User:ystxId output numeric 1 -1
User:ourceSys input varchar 0 -1
The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.
At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.
I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.
Thanks much,

How to parse a string to equal length substrings in SQL
I am getting a long concatenated string from a query (CTVALUE1) and have to use the string in where clause by parsing every 6 characters..
CREATE TABLE [dbo].[PTEMP](
[ID] [char](10) NULL,
[name] [char](10) NULL,
[CTVALUE1] [char](80) NULL
)
INSERT INTO PTEMP
VALUES('11','ABC','0000010T00010L0001000T010C0001')
select * from ptemp
after parsing I have to use these values in a where clause like this
IN('000001','0T0001','0L0001','000T01','0C0001')
Now ,the values can change I mean the string may give 5 values(6 character) today and 10 tomorrow..So the parsing should be dynamic.
Is there now any way to store connection strings for use in SSIS packages in the machine.config with SP2?

I have code being converted from a SQL 6.5 DB to SQL 7; SQL 7 does not concantenate NULLS like in 6.5, so i have replaced all occurances of concantenated NULLs with zero-length strings (''s); in SQL, the view displays the zero-length strings properly, but when i view the linked view in Access97, the zero-length strings are displayed as spaces; is this a SQL problem or an Access Problem? Is there a solution?
Example of display:
10132 Hampton, VA: A. Deepak Publishing
SELECT PublisherID, Info = CASE WHEN City IS NOT NULL
THEN City + CASE WHEN State IS NOT NULL
THEN ', ' + State ELSE '' END + ': ' ELSE ''
END + Publisher
FROM tblLibraryPublishers
When view is linked in Access97, the display will be:
10132 Hampton, VA : A. Deepak Publishing
(this spacing can produce a number of lookup/search problems if only the Publisher name is displayed because a space is added to the beginning of the Publisher name)
Thank you!

Hi all,I need to change a varchar from 35 to 50. In the SQL Server books online it says that SQL Server actually creates a new table when youchange the length. I ran a test in a test database and it appears theonly thing that changes is the length. All the data remains in tact.The table with the column I want to modify is very critical. Is thereany chance I would loose data if I change the length to a larger size? Iam making a back up of the table just in case. Thanks,Kelly

what is the best way to do with out dropping the table?
I have a bit of a dilema, that maybe someone can give a reccomendation on. I have a vb app that will calculate a duration that a process runs in hours:minutes:seconds. My question is should I store this in the database as a date/time field or calculate total seconds and store it as an integer field? I will be using this field for basic summing calculations in the future. Thanks for any help.

View 5 Replies View RelatedI am building a data warehouse. Some of the data comes from an AS 400 EPR system. I used the OLEDB connector when first pulling the data into SQL Server doing simple import data from table option. That worked great for getting the initial data load into SQL Server and creating the base SQL Server tables although it was excruciatingly slow (that was probably due to the transport from the AS 400).
Now, I need to get new records that are added to the AS400 side of things on a daily basis. For that, I was trying to use the OLEDB AS400 connector. However, I found that the OLEDB connector wouldn't work when I was trying to specify an SQL Statement for what to get; i.e., a simple query like Select * from TWLDAT.STKT where BYSDAT >= '2005-01-27' would simply not work. Found articles here explaining that it is probably a problem on the AS400 side of things and where people recommended using an ADO ODBC data reader source for this type of thing. So, I'm trying to implement that. However, I have a huge problem with it.
The original tables that got created were mapped to use NVARCHAR fields for character data. When the ADO ODBC data reader source accesses the AS400 data, it insists on interpreting the string type fields as being unicode strings and giving it a data type of DT_WSTR when what I need it to have is a plain old DT_STR data type. When the strings are interpreted as unicode strings, they cannot be converted in a way that allows the NVARCHAR fields to be filled with the data. The exact error message I get for all the fields that should wind up being nvarchar fields is as follows:
Column "BYStOK" cannot convert between unicode and non-unicode string data types.
Okay, so I try to change the data types in the ADO ODBC data reader to be plain DT_STR data types and I cannot do so.
Does anyone have any idea why the ADO ODBC data reader source insists on interpreting the string data coming from the AS 400 as unicode string data or why it refuses to allow that to be changed to DT_STR data type?
Thanks in advance for any info. By the way, if there is a better way than the ADO ODBC data source to get at this data when I need to specify an SQL command, I would love to hear about it. Not wild about using ODBC in the OLEDB age.

What is the maximun length of a string a variable in SSIS can handle?

Hi,
we can use 'sp_executesql' to execute any statemens. I have made a search and people, seems, need the dynamic sql only to process some table/cloumn unknown in advance. My idea is that the dynamic SQL feature is ideal for passing blocks of code (aka delegates). Particularily, you may require to execute different procedures under some acquired locks. A procedure would acquire the locks, execute the code and release the locks. The problem is, however, that I cannot find the specification for the variable length parameters. It seems not feasible for SPs. Nevertheless, the 'sp_executesql itself does accept the variable number of parameters. How? Can we look at the defenition?
Hi,
I want to export one CSV file to a SQL table.
My problem is my Csv File is variable length file like :
000;1;amruth;20000
000;1;amruth;20000;praveen;shell;floor11
000;1;amruth;20000;praveen;shell;floor11;aaa;aa;aa;aa;aa;aa;aa
Sql Table is like col1- - - - - - - Col 15
I want to make a package to import that variable length Csv to This Sql table like
000 amruth 20000 Null Null Null Null Null Null Null Null Null Null
000 amruth 20000 Praveen shell floor11 Null Null Null Null Null Null Null
000 amruth 20000 Praveen shell floor11 aaa aa aa aa aa aa aa
I hope you got the problem.
I tried with BulkInsert using ; as column Delimiter and as Row Delimiter
and Flat File connection with Same Delimiters but its not working.
its importing like :
000 1 amruth 20000
000 1 amruth 20000;praveen;shell;floor11
000 1 amruth 20000;praveen;shell;floor11;aaa;aa;aa;aa;aa;aa;aa
its inserting like this in 4th column.
If any body can help me on this please reply Asap.
Thanks in advance
I have created a kind of search function in my Excel sheet where the user can select multiple items from different listboxes.
To save the items I use an array. So in one case only 1 items off the array is filled, but another time maybe 3 items are filled in the array.
I use the array to search in a SQL database (this is string rva(i) in the code). But when the array is empty it results in an error.
This is what I have so far. (the rule at the bottom won't work also )
rc.Open "SELECT [Datum],[RvA_Nr], [RvA_Letter], [Afdeling], [EVAL], [Matrix], [Component], [AS3000], [AP04], [Rec] FROM dbo.QHSE_2ndline_history " _
& "WHERE [Afdeling] = '" & afd & "' AND [Datum] >= '" & datum1 & "' AND [Datum] <= '" & datum2 & "' AND " _
& "CASE WHEN '" & rva(1) & "' <> '' then [RvA_Nr] = '" & rva(1) & "' END AND" _
& "([Matrix] LIKE '%" & matrix(1) & "%' OR [Matrix] LIKE '%" & matrix(2) & "%' OR [Matrix] LIKE '%" & matrix(3) & "%' OR
[Code] .....
I'm new to SQL Server. I installed a copy of 6.5 on my server and set it up today. I received a db from a colleague and have been unable to find out what the variable types and lengths are. This may be very easy but I need to know.

Hi,
I'm trying simple code:
declare @varbinary varbinary(8000)
set @varbinary = 2592
print len( @varbinary )
number length
2590 4 bytes
2591 4 bytes
2592 3 bytes ????
2593 4 bytes
All number in range 1 - 9000 has length 4 bytes except these numbers:
32,288,544,800,1056,1312,1568,1824,2080,2336,2592,2848,3104,3360,3616,3872,4128,4384,4640,4896,5152,5408,5664,5920,6176,6432,6688,6944,7200,7456,7712,7968,8480,8736,8992
These numbers has length 3 bytes !
Why?
I´m using varbinary variable to transport ID values and parsing in loop
set @cnt = len( @binEmpIDList ) / 4 -- 4 length
....
insert into @List( ID ) values( substring( @varbinary, @i * 4 + 1, 4 ) )
...
but this algorithm malfunctioning in enumerated numbers.
Please help, how correct this.
ID values in @varbinary too much. I cannot using convert varbinary to bigint and convert bigint to string.

Hi,A query is exceeding the length of varchar and nvarchar variable.Because I'm picking the data from each record from table and giving itto the query.suggest me some way to do it.sample query:SELECT P1.*, (P1.Q1 + P1.Q2 + P1.Q3 + P1.Q4) AS YearTotalFROM (SELECT Year,SUM(CASE P.Quarter WHEN 1 THEN P.Amount ELSE 0 END) ASQ1,SUM(CASE P.Quarter WHEN 2 THEN P.Amount ELSE 0 END) ASQ2,SUM(CASE P.Quarter WHEN 3 THEN P.Amount ELSE 0 END) ASQ3,SUM(CASE P.Quarter WHEN 4 THEN P.Amount ELSE 0 END) AS Q4FROM Pivot1 AS PGROUP BY P.Year) AS P1GO---> even the P.QUARTER ....

i have a test
I have a requirement to import a file of rows containing fixed length data. The problem is that each row can be one of 5 different formats (i.e. different columns) -- where the "type" of row is indicated by the first two characters of the row. Each row gets inserted into its own table.
Could I use a simple Conditional Split to route the rows? Or is the split for routing similiar rows? Anyways, problems are never this simple...
In addition, each "grouping" of rows is related. The "first" row is considered the "primary" row (and gets a row id via IDENTITY, whereas the remaining rows in the group are "secondary" rows and have foreign key references back the the primary rows id.
Given (using spaces to separate columns and CrLf to show "grouping"):
01 MSFT blah blah
02 blahblah blahblahblah
03 boring boringblah
01 AAPL blah blah
02 blahblah blahblahblah
03 boring boringblah
01 CSCO blah blah
02 blahblah blahblahblah
02 blahblah blahblahblah
03 boring boringblah
So, the first 3 lines are all related to a MSFT record which needs to be spread across multiple tables. The next three lines are all related to AAPL, And the next FOUR lines (yes, each record can have zero, one, or more secondary rows) are related to CSCO.
(If this is still not clear, all the "01" rows will be written to [Table1] with each row having an IDENTITY value. All the "02" rows will be written to [Table2] the a FK pointing to the correct [Table1] row. All the "03" rows will be written to... and so on.
Any ideas would be appreciated.
I am running SQLServer 2000 to parse and store records in the EDIX12
format. This consists of variable length delimited records which
I am passing to the "transforms" tab to process with VBScript.
The problem is though each segment has a defined number of fields, N,
the standard states that if the final M fieds are empty/blank they are
not to be sent. Thus, a segment defined to have 20 fields may
have 6 the first time I see it, 13 the next time, etc. To access
the columns in VBScript I use DTSSource("Col001"). This works as
long as the columns are there, but gives an error when they are
not. Is there a parameter telling me how many columns are
defined? Or is there something akin to IFEXISTS("Colxxx") or
exceptions?
How can I handle this situation? One suggestion has been to pass
the entire segment to the Transforms section and break it up there.
Finally, what resources can yuo point me to for reference? I'd
like to get good at using DTS since my client wants their project
written for it.
Thanks for yuor help,

Can someone tell me how to store the results of a multi-row query in a text or varchar variable so that I might do something like this:

I know this can be done, because I saw it and tried it once. But did not use it at the time and consequently forgot how.
I am storing an expression to a variable @Var Varchar(50)
@Var = ('aa','bb','cc')
I want to:
Select * from Table WHERE Field IN @Var
Substituting my variable for the " ('aa',bb','cc') which I can build dynamically...thus the use.
Purpose:
I have an aggregate query that currently has a CASE statement based on the contents of ('aa',bb','cc'). However, those contents can change. The aggregate will not allow the subquery (SELECT Field FROM Table).
What I remember looked something like:
SELECT * FROM Table WHERE field in ' & @Var &'.
