Using TEXT Datatype As Local Variable In SP Or UDF
Mar 12, 2003
I've created a stored procedure that converts an input string in richtext format (input as type TEXT) to plain text. I would like to be able to return this newly converted string, but I need to have some way of storing it in a local variable. My problem is that since I can't use the TEXT datatype as a local variable, I have no way of storing the large amounts of text I converted within the procedure. The VARCHAR(8000) just isn't large enough for my purposes. Anyone have any suggestions on how to go about doing this?
Friends,I would just like to know that why SQL Server doen't allow us to definea text data type local variable while creating trigger?I tried creating a text variable in a trigger as a local variable andit raises error."Implicit conversion from data type text to nvarchar is not allowed.Use the CONVERT function to run this query".For this i have to use convert function in MS SQL Server.-ThanksBhavin Vyas
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:
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.
i have so doubts in my mind and that i want to discuss with you guys... Can i use more then 5/6 fields in a table with datatype of Text as u know Text can store maximu data... ? acutally i am trying to store a very long strings values into the all fields. it's just popup into my mind that might be table structer would not able to store that my amount of data when u use more then 5/6 text datatypes...
and another thing... is which one is better to use as data type "Text" or "varchar(max)"... ? if any article to read more about these thing,, can you refere to me...
The DATEDIFF(s, time1, time2) function output is of the 'datetime' datatype. How can I alter the 'datetime' to 'int' (or 'bigint') datatype to make it compatible with other variables in my calculations?
I have image type col.I'm trying to do the following,DECLARE @Data varbinary(16)SET @Data = (select imageCol from Table1 where id=3)As image datatype returns varbinary value, so I want to store image col value to a varbinary variable(or any other type variable, eg., varchar). But getting following error,========================================Server: Msg 279, Level 16, State 3, Line 2The text, ntext, and image data types are invalid in this subquery or aggregate expression.========================================Is there anyway to store image datatype value to a variable?Cheers.
hi everyone, How do i declare a global variable in my package which takes a numeric value like User::VAR1 = 200402 and later on work on it
Later in the properties of the Dataflow i want to have this expression..
"select * from " + "TAB1" + " where Date=" + @[User::VAR1]
Here i want to subtract 190000 from @[User::VAR1] to get it in to myformat i.e the DATE format in the table
I can only see String datatype and othe datatypes wont allow me to to do any kind of manipulation in the expression: and to be more specific what are Int16 Int32 Int64 Double
I tried to use all of the above but the expression doesnt allow me as it says:
TITLE: Microsoft Visual Studio ------------------------------
Nonfatal errors occurred while saving the package: Error at Extract: The data types "DT_WSTR" and "DT_I8" are incompatible for binary operator "+". The operand types could not be implicitly cast into compatible types for the operation. To perform this operation, one or both operands need to be explicitly cast with a cast operator.

I am trying to create a procedure or function that will deal with weekly information for staff records.
Rather than declaring 14 local variables for the information, is it possible to declare a local variable as an array? Sorry for using VB terminology - not sure how SQL would describe it.
From the BOL, what I understood is, Text Datatype can accept more characters than 'char' & 'varchar' datatypes. There is no limitation like 8000 characters(what we hv in 'char' & 'varchar').
But I am surprised I am not able to add more than 8000 characters to my text datatype. Can anybody guide me how to do this?. Any help is appreciated.
i have a column type text i want to perform split functionality that is not currenctly availablein mssql server 2000.
to achieve this i have to used len() , left() right() and substring() functions incase of varchar datatype.. but len(), right() and left() functions are not supported for text datatype....
I have to create Sum() in SSRS for my report. My field data type is TEXT and i can not create sum function in ssrs. I can not make change to data type since it is linked table in access database. Is there any way to sum text data type???.
I have a problem within a procedure I am working on. I would like toprocess every column in a table in a cursor. Now to my problem, Ican't save a column of type text into a cursor variable. It's notallowed to use datafields of type text in this context. I also thinkthat I runned in to a simular kind of problem when trying to use textcolumns in triggers.Is there a way to evade this problem or is the only solutions to putthe text colum value into a varchar(8000)?Regards,Jenny
Why can varchar datatype variable only 4000 byte? For example: in a storedprocedure declare @aa varchar(8000) ...... while select @aa=@aa+@otherinfo end when the length is more than 4000 ,the data in the behind will be lost
* My problem is that I want to update the field A.CdeTour depending on the data present in B.
Let's take the first line from the table A: the number of the street 'well.' is '25', and '25' is odd and between '1' and '41' which meens that I should update my field A.CdeTour should be set to '100' (B.CdeTour). Let's take another example, so in the second line: the street is still 'well.' but here the number is '50'. '50' is even and between '42' and '84' so the field A.CdeTour should be set to '200' (B.CdeTour).
Here I wrote a query, which doesn't work properly:
DECLARE @Num VARCHAR(4) UPDATE A SET @Num = Number, CodeTournee= CASE WHEN @Num % 2 = 0 THEN( -- even number of street SELECT CdeTour FROM B WHERE @Num BETWEEN FirstEven AND LastEven AND A.PostCode = B.PostCode AND A.Street = B.Street )ELSE( -- odd number of street SELECT CdeTour FROM B WHERE @Num BETWEEN FirstOdd AND LastOdd AND A.PostCode = B.PostCode AND A.Street = B.Street )END FROM A, B
The query runs but the problem is that it doesn't update the field, because it doesn't interpret @num by its value.
In fact, if instead of @num, I hard-code a value it works ... WHERE '0025' BETWEEN FirstOdd AND LastOdd ...
Can someone help me???? I would be very pleased, if someones could give me another way of doing it or a trick in order to avoid this problem.
Set @Test='SELECT VIOXX_LastName + '' + VIOXX_FirstName + '' + CONVERT(varchar(50), VIOXX_Number) AS PlaintiffsName, VIOXX_Number FROM tblPlaintiff WHERE VIOXX_Number NOT IN(SELECT VIOXX_Number FROM tblCase_Plaintiff) OR VIOXX_Number IN (SELECT tblCase_Plaintiff.VIOXX_Number FROM tblCase INNER JOIN tblCase_Plaintiff ON tblCase.Case_Number = tblCase_Plaintiff.Case_Number WHERE (tblCase.Status = ''InActive'')) ORDER BY VIOXX_Number, VIOXX_LastName' Select @Test
and get the following result: SELECT VIOXX_LastName + ' + VIOXX_FirstName + ' + CONVERT(varchar(50), VIOXX_Number) AS PlaintiffsName, VIOXX_Number FROM tblPlaintiff WHERE VIOXX_Number NOT IN(SELECT VIOXX_Number FROM tblCase_Plaintiff) OR VIOXX_Number IN (SELECT
the latter part of my original text is not stored in the variable. Is there some limitation on the number of characters for a local variable in transact sql?
Hi guys I am sitting and testing som variants of this simple SP, and I have an question that I couldent answer with google or any thread in this forum.
Perhaps I am doing something really easy completly wrong here.
Why does the local variables in the first code segment slow down the overall execution of the procedure? Dont mind the logic why I have them there are only testing som things out.
If i declare two variables the same way: DECLARE @v INT SET @v = 100
When I use it in a WHERE CLAUSE: ...WHERE [V] BETWEEN @v AND @x) Is there any different then ...WHERE [V] BETWEEN 100 AND 200)
Cant figure this out, why does it hurt the performance so bad? As a C# guy its the same thing ?
Thanks in advance /Johan

I have a cursor that loops over a table and I use a local variable to append the column data. However when I try to print this variable, it comes as empty!
Is there an expression syntax for putting a local variable value into a text box like there is for putting a parameter value? I'm using the report builder via VS

I need to replicate a table with datetime,char and text datatypes.Is it possible to replicate text datatypes?What is the alternate if not?It should be merge replication.Please reply. Thanks.
I am trying to use the TEXT datatype for a column to hold large amounts of ascii data.
Creating the table from script I use: create table mytable ( firstcolvarchar(30) not null, secondcolTEXT not null ) go
The field will not accept strings in length over 16 chars. I looked at the table design in the enterprise manager and it shows 16 chars as the width.
I tried creating the table with TEXT(32000) but I get "The size (32000) given to the column 'secondcol' exceeds the maximum. The largest size allowed is 8000." I thought that TEXT fields are what you use when the length is over 8000. What do I need to do to enable this type of data storage? thanks in advance.
OK, I`ve been researching the use of the TEXT datatype all day and would like opinions on what I`ve found.
First, a little background. I have been tasked with writing an ASP application to handle the display of FAQs for a company`s products. I would like to store all info in a table much like
faqID int question TEXT answer TEXT
Simple enough, right? I then tried to create a stored procedure to add a new FAQ and all hell broke loose. ASP would not pass anything larger than 255 chars to the stored procedure.
I read in the "ADO and SQL Server Developer`s Guide" from Microsoft about using varchar datatypes of 255 chars (instead of TEXT) and chunking large text up to fit in these smaller datatypes. This seems like a lot of work.
I also read in "Inside SQL Server 6.5" that "The text datatype is sometimes awkward to work with. Many functions don`t operate against text, stored procedures are limited in what they can do with text, and some tools don`t deal with it well." (page 632). This statement concerns me greatly. How are stored procedures limited in dealing with TEXT? Do the standard SQL UPDATE and INSERT commands work or must READTEXT and UPDATETEXT be used instead?
I guess my question is, what is the best way to accomplish this? I have a feeling that others have had to do this before. Is SQL Server not meant to handle large textual objects? Is chunking the best way to go? Will version 7.0 handle this scenario better?
I'm trying to do a simple search for any record that has an empty 'dsc' field. There isn't a NULL character in there, just a SPACE character. The 'dsc' field is a description field so it's datatype is TEXT.
Code:
SELECT id FROM leads WHERE dsc<>''
Normally I can do a VARCHAR(50) like that and get the results I'm looking for. When I do this on a TEXT datatype I get this error:
The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator.
I I tried a couple of things, but it's not getting me the correct results.
Code:
SELECT id FROM leads WHERE dsc NOT LIKE '% %' SELECT id FROM leads WHERE dsc NOT LIKE '% ' SELECT id FROM leads WHERE dsc NOT LIKE ' %'
Please shed some light on this.. thanks!
Edited @ 12:08 PM After some research I found an unconventional way of beating the system. If you have a more conventional way I would still like to see it. A quick fix is using DATALENGTH() function to compare the data. Basically if there are any characters besides NULL and space then the data length will be more than zero.
I have a number of bit datatypes ( Boat types: Cruiser, Sportfisher, Megayacht, Sailboat) that I would like to place in a text box and do away with the individual selections. For instance, some marinas cater to "Cruiser", "Megayacht" and "Sailboat" while others include the "Sportfisher" also and there are many other combinations of vessels. I am stumped at how to write a query that takes the existing "True" values for each boat type and places them in a text box in the form of " Cruisers, Megayachts, Sailboats" .
