How To You Convert An Oracle Long Field To Varchar 8000
Jan 17, 2007
I need to handle this conversion in SSIS and not on oracle.
The following expression is executed on a datatype of dt_str with a length of 8000.
SUBSTRING((DT_STR,8000,1252)Column_name,1,8000)
Records longer then 4000 bytes take an error path
The next expression with 4000 bytes works but there is truncation.
SUBSTRING((DT_STR,4000,1252)Column_name,1,4000)
Basically I need to know how to cast a text or ntext into a varchar or nvarchar using ssis but I need to capture the first 8000 byes without truncation.
is this possible?
Using SSIS Reading From oracle I can convert to a text or ntext field but I am having a hard time going directly to a varchar.

I am trying to change a text field into a varchar 8000.
I get his error message when trying to convert.
Unable to modify table.
ODBC error: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot create a row of size 8317 which is greater than the allowable maximum of 8060.
[Microsoft][ODBC SQL Server Driver][SQL Server]The statement has been terminated.
Anyone know of a way to either truncate the text field or
to select only those that are over the 8000 character mark?
Please advise
Thanks

Does anyone know of a way to execute sql code from a dynamically builttext field?Before beginning, let me state that I know this db architecture isbuilt solely for frustration and I hope to make it better soon.Unfortunately, there is never a non-crucial time in which we can do anupgrade, so we are stuck for now.Point 1:There are multiple tables: students, courses, cross-referencestudent/courses, teachers, cross-reference teacher/courses, andothers.Point 2:Yearly archiving is done by appending a 2 digit year suffix to thetable and rebuilding the table structure for the current year. Thatis, each of the tables named above has an archive table for 1999,2000, 2001, etc. This leads to many tables and a big mess whenunioning them.Point 3:A history report is run by building a big query that unions each unionof tables (students, courses, etc) by year. This query has grown toobig for a varchar(8000) field. Actually, it's too big for 2 of them.Point 4:I don't want to write code to maintain any more varchar(8000) fieldsfor this query. It should be much more easily handled with atemporary table holding each bit of yearly archive data. I have builtthis and it works fine. I have also figured out how to pull the rowsfrom that table, concatenate them, and insert the resulting lump intoa text field in another table.Point 5:I haven't figured out how to grab the 5 or so records from that tableand execute them on their own. I figured I could grab them, put theminto a text field that's big enough to hold the whole query and thenselect and execute that text field. I've had no luck with that and Ihaven't had any luck finding any references that might help me withthis problem. I keep thinking of nesting execute() calls, but thatdoesn't work.I'm open to questions, potential solutions, hints about different wayto approach the problem, anything.Many thanks in advance,Rick Caborn

I am having a problem while converting datetime to varchar with code 106. Here is the code and result I get:
TSQL Code:
SELECT CONVERT(VARCHAR(100), GETDATE(), 106)
Result:
"26 10 2007"
My expected result:
"26 Oct 2007" or "26 October 2007"
Have you encountered this problem before? Is it related to the SQL server setting? Please help and thank you in advance.

Hello,
I have a table with a column that is currently a varchar(50), but I want to convert it into an int. When I try to just change the type in design mode I get an error that conversion cannot proceed. When I look at the field it appears some of the entries have special characters appended at the end, I see a box after the value.
How can I remove all speical characters and then convert that field to an int?
Also I tried the following query which did not work as well, same error about conversion.
UPDATE myTable SET field = CAST(field AS int)

I'm trying to convert a column in my source table of datatype varchar(6) to a column of datatype int in my destination. I tried using the Derived Column/Data Conversion transformations but none of them worked. So, I tried using the following C# (credits to the original poster) and getting an error during compilation.
Note: "MyCol" is the Input Column I've specified in the Script Component and "CleanCol" is the Output column I've specified as datatype [DT_I4].
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
int colOut = 0;
if (!Int32.TryParse(Row.MyCol, out colOut))
{
Row.CleanCol_IsNull = true;
} else {
Row.CleanCol = colOut;
}
}
The best overloaded method match for 'int.TryParse(string, out int)' has some invalid arguments
The other expression I've tried was:
ISNULL(MyCol) ? (dt_i4)"" : (dt_i4)MyCol
From the above code, you might have understood that the source field has some blank records as well in the MyCol field.
What is the best possible way to do the conversion from a String to Int or fixing the error from the above.

Any way to parse out a text value (not varChar, using text data type) that is > than 8000 characters long? I'm looping through 1 big string passed to the DB that is pipe delimited, but I find myself needing the substring function to keep track of which segment I'm acting on (after an update, I then need to take that segment and remove it from the string)...but the subString function won't take anything larger than 8000 chars.
Say I have this string that is text data type...
'aaa|bbb|ccc|ddd|....'
..and so on, surpassing 8000 char length, how could you parse it out using the pipes as the delimter, then do an Update using that segment? Afterward, return to that string and find the next segment, then use it, and so on (in a loop). I tried using an update to set the string = replace(string, segmentJustUsed, '') to "erase" it, but replace can't take text as the datatype. Any help? Hope this isn't to confusing.

Hi,
I had a VARCHAR(MAX) parameter declared in my stored procedure and trying to concatenat single column from a table which has~500 rows into a string and keep in this variable, if i am not mistaken, i read that the VARCHAR(MAX) actually can hold up to 2GB of data, so it make me confuse why the variable which i declared as MAX size, can only hold up 8000 characters, any idea?
Regards,

I was trying to build a string based on one field from one table in Stored Procedure. I know if I declare A VARCHAR variable for the string, it won’t allow to exceed 8000. If does, it will truncate the reminding parts of the fields. What might be the simple solution for that? Even though I know I might need to use several substrings but how?
Thanks!

hi all, I'm after a way to produce a single-lined output of a char/varchar string replicated over 8000 times.
basically I've been given a task to create a stored procedure which can accept any integer to replicate a string X times.
From what I've read the replicate() fn will covert to varchar of max 8000 bytes.
I've thought about creating a UDF to accept the varchar and int and run a loop to keep outputting but 'print' will pass an endline to the buffer which is no good for my loop.
Any help would be great on this. Thanks.

Hello,
We have migrated a sql server 2000 database to sql server 2005, this was done through scripts (table, stored procedures and data).
To access this database we are using an ASP.Net 2.0 application which uses the sqlhelper Aplication Block to connect to the database.
Everything works fine except one Stored Procedure which has an OUT varchar(8000) parameter.
We use the following .Net Code to execute the stored procedure this stored procedure:
aParams[2] = sSerDatos.GetParameter("@DominiosMenu", DbType.String, 8000);
aParams[2].Direction = ParameterDirection.Output;
sSerDatos.ExecuteNonQuery("VM_SDominiosMenu", aParams)
When we invoque the sqlcommand we get this sqlexception:
The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 3 ("@DominiosMenu"): Data type 0xE7 has an invalid data length or metadata length.
If we change the DbType.String Size to 4000 in the .Net code everything works, this same procedure work correctly in SQL Server 2000 with the same .Net code.
Any help would be appreciated.
Thanks,
Sam

I have this sql statement in a stored procedure
SELECT @sql=@sql + '''' + convert(varchar(100), pivot) + ''' = ' + stuff(@sumfunc,charindex( '(', @sumfunc )+1, 0, ' CASE ' + @pivot + ' WHEN ' + @delim + convert(varchar(100), pivot) + @delim + ' THEN ' ) + ', ' FROM ##pivot
in the statement, where @sql is defined as DECLARE @sql varchar(Max). the problem is that this statement produces results that are in excess of 8000 characters and the results are truncated. Is there anyway to avoid this? I know that it's not possible to user ntext/text as a local variable, and if i try to return the result as an ouput paramater, only the first result is returned.
my code is based off of this article http://www.sqlteam.com/article/dynamic-cross-tabs-pivot-tables
Thanks for any suggestions.

Hi
I need to pass the where clause of my statement as an input parameter for a stored procedure. As this is built dynamically within the program (Borland C++), it could sometimes exceed the maximum 8000 bytes of a varchar. I thought of sending in two input paramenters and concatenating them into a memo in the sql, but cannot seem to be able to execute the memo variable (i.e. exec(memo) doesn't work). Is there any other options for passing in such a huge parameter.
Also, I do not think there is any other option than passing in the where clause: passing in seperate parameters and building the clause in sql would require over 300 parameters to be passed, and as the possible number of combination is indefinate, I cannot have a different Stored Procedure for each potential case.
Thank you

I have a table containing URLs. I want to be able to look up an URL veryfast, so I used an nvarchar to store the URL, and put an index on it(maybe naive).Anyway, I bump into:"The index entry of length 911 bytes for the index 'UQ__URL__1367E606'exceeds the maximum length of 900 bytes."What's the best way to handle this? I want to do the look up fast. Theonly thing I could think up was adding an extra column containing a digestfor the URL, and look up all URLs with the same digest, *and* having thesame value (which could give either 1 or 0 results).I am new to MS SQL, so I might describe a silly solution, basically I wantto look up URLs to ID the fastest way possible.--John MexIT: http://johnbokma.com/mexit/personal page: http://johnbokma.com/Experienced programmer available: http://castleamber.com/Happy Customers: http://castleamber.com/testimonials.html

(I'm using MS SQL 2000)
I've two tables that I've made from some query subsets. Each table has a varchar field with notes/memos and I want to concatenate the fields into one long field.
The problem I'm running into is that when I run the query to check the concatenation, the field is truncated maybe 256 chars in.
I tried converting and casting the field as nvarchar 4000, and I've also done the same for the fields in the two tables, but that doesn't seem to help.
I can query for the fields from each table and none of them are truncated by themselves. It only happens after I concatenate them.
I've created a new table and inserted the results into it, but the field in it is also truncated.
Am I missing something obvious here?

I've noticed that when a dataflow task returns an Oracle LONG field. If the query involves one table, the LONG is returned normally. If the query involves any simple joins, the LONG will be truncated at the first 100 characters.
The Microsoft driver does work correctly.
Has anyone else experienced this with the Oracle driver and are there any known work-arounds?

Hi.
I need to convert a vb function into a user-defined function in a stored procedure.
The vb function converts a long datatype into Date datatype.
Here is the VB function:
Function LongToTime(lTime As Long) As Date
LongToTime = (lTime 10000) / 24 + ((lTime Mod 10000) 100) / 1440 + (lTime Mod 100) / 86400
End Function
The function is used to convert a timestamp(hhmmss) into a more readable format.
Would it be possible to create a function similar to this in an SQL stored procedure?
Thanks in advance

I am trying to run this statement
Select Calims, ProCode From Inquiry Where ProCode Between 80000 and 89999
ProCode is a varchar but I am still checking a range on it.
It seem to work fine but then there is some invalid data entry in this column
for example 'abace' or '100i' so I get the error.
1) how I can exclude them out of my query.
Someone suggested the following but I dont understand how do achieve that. thanks
" However, there would appear to be different data types. If Value is a character
--based type then you may want to limit the search by first extracting numeric values
-- with something like ISNUMERIC(Value) = 1 and then converting them to numerics using
--the convert function - CONVERT(int, Value) BETWEEN 10000 and 20000."

Hi All,
I'm having an irritating issue transfering data from SQL server to Oracle.
I recieve a fixed width file and insert it into a SQL server staging table. with fields of varchar(30). after insertion, I can run the following:
Code Snippet
select len(contact_surname)
from customer_data
and get varying lengths, 7, 5, 9, etc....
after a very simple data flow which takes the data from the SQL server source and inserts in to the Oracle Destination, the same query in oracle:
Code Snippet
select length(contact_surname)
from customer_data
gives me a length of 30 characters for every record. they've been padded out to 30 characters with spaces. the table in oracle is identical to the SQL server one in every way except for using oracle's varchar2 of course.
there is no extra transformation or anything happening in between systems. I would expect this to happen if the oracle table had fields of typ char() which would pad out to the length of the field, but not for varchar2.
SSIS appears therefore to be appending data in the move to oracle.....
[sarcasm]
or am I missing some magic function in SQL server that will tell me the REAL length of the field..?
[/sarcasm]
it seems awkward to transfer the data and then have to trim every field again.... any thoughts?
