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.
Thanks,

I'm trying to build a process within SSIS and running into a large number of road blocks. I could just drop out into T-SQL and code this entire thing, but I'm trying not to do that so that I can take advantage of the parallel processing pieces as well as learn a few things along the way.
Here's the overview of what I need to do on a daily basis:
1. FTP files to a local directory which I haven't already grabbed
2. Make a copy of the files into an archive directory
3. gunzip the files in my working directory
4. Remove any zero length files
5. For each file in the directory, run a data flow task
6. At the successful completion of the data import, log the imported filename into a table, along with the row count
7. If 6 is true, delete the file from the working directory
I gave up trying to get the FTP task to do #1 and I also gave up trying to get a script task written to do this. So, I wrote a stored procedure that will grab any files off an FTP site that are not already in my archive directory.
I figured out that the File System Task is incapable of handling wildcard characters to basically do "copy *.gz...". I could have done this in very little code within TSQL as well, but decided to use a for each loop to go 1 file at a time and use the file system task to copy the file.
I've already setup the for each loop with the execute process task to do the gunzip of each file in the directory. I also figured out how to suppress the pop up window as well as make it ignore any error messages. (Some of our files get an "unexpected eof" from gunzip, so that I know when we're done with the process, anything with a .gz extension had an error unzipping and needs to be kicked back to the provider.) I do have one issue with the fact that the execute process task leaves a copy of gzip.exe running in memory that leaves the last file locked and has to be killed manually.
Now, I'm to the zero length files issue. There isn't anything in the file system task to let me perform operations based on a file attribute. I can do this using TSQL by shelling out through xp_cmdshell and running a dir /-C, piping that to a file, BCP the file into a table, and then string parse the file names for everything with a length of 0 and then issue a delete command. I would really rather not do that. I'm fairly certain that I can do this in WMI, but I have no idea how to code that. Essentially, what I want to do is fire off a WMI query that pulls back a list of files in a given directory with a length of zero, hand that list to a for each loop, log each zero length file name into a table within SQL Server that it was processed with 0 records, then delete the file.
Two questions:
1. Anyone know how to get the Execute Process task to not leave the last instance of the exe running when it completes?
2. Anyone know how to get a list of zero length files from a specified directory to feed to a for each loop?
What is the maximun length of a string a variable in SSIS can handle?
I assume it is 8000 ?
Hello folks!
I have written a stored proc that selects data from this table:
A1 AA
A2 BB
B1 AAA
B2 BBB
and puts it another table in this manner:
A1 AA BB
A2 AA BB
B1 AAA BBB
B2 AAA BBB
In short, I wanted to concatenate data in the second column.
My question is for some reason, SQL Server is limiting the length of the string to only 256 characters, even though I have defined the local variables in the storeds proc as varchar(1000) and the table has that field defined as text.
Any ideas how I can get around this problem?
Thanks!

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 need to store quite along description in the database, which in anyother database i would choose the data type 'text', however, can someone tell me why the length is set to just 16 in sql server..... i have seen a text field with far greater than 16 chars, set at length 16, so what does this length of 16 mean?????
also what is the max length of the text field?
thanks
Below is a SQL statement that shows what columns belong to a certain view. My next question is how can I get a third column that shows the column type ?
VARCHAR(100), or UNIQUEIDENTIFIER or INTEGER or TEXT or NVARCHAR(256) or ........????
select top 100 a.name, b.name, from sys.views a inner join sys.columns b
on a.object_id = b.object_id where a.name like '%Case_Times%'
Folks:
I would like to know the total length of data type in a table. I ran the following query. Will this give me the correct information? I also ran sp_columns <table name> and it too give the length. But There is a difference in the numbers. Am I doing something wrong and which is the correct the query or sp_column.
select sum(length) from syscolumns
where id in (select id from sysobjects
where name = 'XYZABC')
sp_columns XYZABC
Thanks !
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.

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 !
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,

I have an SSIS package that creates a csv file based on a execute sql task.
The sql is incredibly simple select singlecolumn from table.
In the properties of the execute sql task I specify the result set as "full result set" when I run it I get the error that: Error:
The type of the value being assigned to variable "User::CSVoutput" differs from the current variable type.
Variables may not change type during execution. Variable types are strict, except for variables of type Object.
If I change the resultset to single row then I only get the first row from the DB (same if I choose none), If I choose XML then I get the error that the result is not xml. What resultset type do I need to choose in order to get all the rows into the CSV? The variable I am populating is of type string and is User::CSVoutput
Hi guys, is there any way to solve my problem as title ? Assuming my stored proc is written as below :

AS
BEGIN
DECLARE @B nvarchar(MAX);
SET @B = 'SELECT * FROM C WHERE ID IN ( ' + @A + ')'
EXECUTE sp_executesql @B
END

I have this doubt and want to be sure if my thinking is correct.
Lets consider 2 tables one with Fixed length columns (char) and other table with Variable length columns (Varchar).
The table with fixed length column will always allocate same size within a Page however, table with variable length column will allocate actual length of data within a page.
I think that updates happening on table with fixed length columns will have more possibility of InPlace updates at least from data length perspective, however updates on table with variable length columns will have more split updates from data length perspective.
I have a situation where I need to determine which type this record is. If type ID is 20, 23, or 25, then select F otherwise it is P.
Select FirstName
,Lastname
,address
, (If typeid = 20, 23, or 25 then F else P) as TypeDesc
From sometable
The number(20,23,25) are hardcoded in the stored procedure and I have them in a variable because there are over 30 different numbers.
Is there a way to check the type of a variable in SQL? I want to knowif a variable is a float or a string.Thanks,Ramzi
View 1 Replies View RelatedHi all,
I am trying to extract certain data from MySQL

variables and then copy the values from the variables and insert them
into a new table in sql server 2005 and has two columns in it (COLUMN1
of type nvarchar and COLUMN2 of type int). I can map the first output
(COLUMN1) correctly to variable type String and store them in the new
table in sql server 2005 (store the value in a variable type String and
then use insert and store it into sql server using parameter in Execute
Sql Task set the data type to NVARCHAR, but I cannot map the second
output (COUNT(COLUMN2)) using the same method, I could not even get it
to store into a variable of any type. Anyone have any idea how to go
about it? Thanks in advance.
The output of the sql statement for MySQL should look like:

is there any way or a tool to identify if in procedure the Parameter length was declarated less than table Column length ..
I have a table
CREATE TABLE TEST001 (KeyName Varchar(100) ) a procedure
CREATE PROCEDURE SpFindNames ( @KeyName VARCHAR(40) )
AS
BEGIN
SELECT KeyName FROM TEST001
WHERE KeyName = @KeyName
END
KeyName = @KeyName
Here table Column with 100 char length "KeyName" was compared with SP parameter "@KeyName" with length 40 char ..
IS there any way to find out all such usage on the ALL Procedures in the Database ?
For those of you who would like to reference my exact issue, I'm dealing with the RSExecution SSIS package at the "Update Parameters" data flow task, at the Script Component.
The script tries to split parameter data into name and value. Unfortunately, I have several reports that are passing parameters that are very large. One example has over 65,000 characters all in the normal "¶mname=value&parm2=value..." format.
The code in the script works fine until it gets to one of these very large parameter sets. I have figured out what is causing the issue. Here's some code:
Dim paramBlob as Byte()
paramBlob = Row.BlobColumn.GetBlobData(0, Row.BlobColumn.Length)
The second parameter of the .GetBlobData function takes an INTEGER as its count! Therefore, no matter what kind of datatype I pass to the string that the script will later split, it will be limited to 32767 characters.
THIS IS A PROBLEM!!!
Does anyone know a workaround for this issue? I need all of the parameter data to be reported, and I would hate to have to skip over rows like this. Also, if I'm missing something, please fill me in!
Thanks for your help in advance,

Is there anyway to change the data type of a variable while in an expression?
My problem is I am trying to compare a variable w/ a string data type to a variable w/ an object data type. I would change the data type of the variable from object to string but if I do that my sql task fails when it tries to write a value to that variable. The variable w/ the object data type is the result of an openquery sql stmnt. So I guess there are two ways around my problem.
1. Change data type of variable while in an expression..ie flow constriant
or
2. Change data type of vraiable from object to string and still get the openquery result to work.
Any help???
Thanks !!
