Friends,
I would just like to know that why SQL Server doen't allow us to define
a text data type local variable while creating trigger?
I tried creating a text variable in a trigger as a local variable and
it 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.
-Thanks

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?

quote:list the first and the last name of the employee with a name of Thomas. Use local variables for the first name and the last name and the @@ROWCOUNT command.
SET NOCOUNT ON
DECLARE @variable varchar(50)
SET @variable = 'name'
SELECT @variable = fname + ' ' + lname
FROM employee
WHERE @variable = '%Thomas%'
IF @@ROWCOUNT > 0
PRINT 'Employee Name is ' + @variable
ELSE
PRINT 'Employee not found'
when i execute it, it said employee not found. what do i need to add or revise?
it should be:
quote:Employee Name is Argon Thomas.
I have an installation script and want to create a database based on some data in a table (config). Testing the script though I get a message:
Msg 170, Level 15, State 1
Line 12: Incorrect syntax near '@DBData'.
The relevant sql is:
declare @DBName varchar (40)
declare @DBData varchar (40)
declare @DBLog varchar (40)
declare @DBSize int
select @DBName = obj_txt from config where obj_nm='DBName'
select @DBData = @DBName + '_Data'
select @DBLog = @DBName + '_Log'
select @DBSize = obj_int from config where obj_nm='DBSize'
raiserror('Creating Database %s ....',0,1,@DBName) with nowait
Create Database @DBName
on @DBData = @DBSize
Log on @DBLog = @DBSize
I don't think there's anything wrong, apart from the fact I am using the local variables. Is this allowed on a Create Database statement? I haven't found anything in Technet that may help.
Here's hoping....
Thanks

Hi
I am trying to use a global variable in a case when and am not getting the correct results. If I use static data, it works fine.
Here is a tableless example, which should return Shipper. Any ideas are appreciated.
Code:
declare @shipperGBS varchar(3000)
declare @sQuote char
set @sQuote = char(39)
set @shipperGBS = 'ACI,ADO,ALD,AMS,AWB'
set @shipperGBS = Replace(@shipperGBS, ',', @sQuote + ',' + @sQuote)
set @shipperGBS = @sQuote + @shipperGBS + @sQuote
select case when ('ACI' IN (@shipperGBS)) then 'Shipper' else 'Consignee' end as ClientCharge
Hey guys, needless to say I'm new at this.
What I'm trying to accomplish is to execute a SQL string via exec and inside it set the value of a local variable. I understand that I cannot do this the way I'm currently doing it because an Executed string runs in a scope of its own so local variables are invisible. And sure enough this is the error I get. So how do I make this work?
Code snip:
declare @ErrMessage as varchar(1000)
set @Sql = 'if exists ( select * from ' + @TargetTable + ' where (' + @ValueField + '=' + '''' + @NewValue + ''''
set @Sql = @Sql + ' and ' + @TagField + '= ' + '''' + @Tag + '''' + '))' + @CRLF
set @Sql = @Sql + 'set @ErrMessage = ''Insertion could not be performed. ' + @NewValue + ' is already an entry in the table. '''
So what I want is check if a certain table has entries...what table? I don't know, there are tens that this check will apply to. And if that tavle has an entry that satisfies the where clause then assign the appropriate error message to @ErrMessage.
I understand sp_executesql might do the trick because it allows passing local params back and forth.
Any ideas on how to make this work? I appreciate the effort.

View 4 Replies View RelatedI have a function that returns a table of matching names. For the most part it returns under 5,000 results which doesn't cause too much lag joining to the search report data (which is indexed). But sometimes there might be 10,000 + search name results. I find this and higher can cause excessive lag joining. Is it possible to index this result table from the function? Or any other suggestions?

I would like to know if there is a penalty for Varchar variables in stored procedures if I declare them Varchar(8000) instead of Varchar(1000).
I have a lot of variables and sometimes the content will be more them 1000 characters.
Is memory only allocated for the the actual contents or for the complete declared length?
I am brand spankin new to stored procedures and don't even know if what I want to do is possible. From everything I've read it seems like it will be. I have a table, punchcards. In this table are all the punch in/out times for a week. I want to create a stored proc to calculate how many hours a punchcard entry is.
Thats the dream.
The reality is that I can't even get a tinyint from a table to load to a variable and be printed out. I am using sql server 8.
Here is what I have as of this moment for my sp.
ALTER PROCEDURE usp_CalculatePunchcard
AS
DECLARE @dtPP DateTime
SET @dtPP = (SELECT thursday_in1
FROM punchcards
WHERE (punchcard_id = 1))
/*
Also tried....
SELECT @dtPP=thursday_in1
FROM punchcards
WHERE (punchcard_id = 1)
*/
PRINT @dtPP
RETURN
/*
for some reason i can't use GO ... even though every
document i've read on stored procedures has used GO
and none use RETURN
*/
The only output this is producing is ' Running dbo."usp_CalculatePunchcard". '
Any help would be greatly appreciated as I am about to kick someone/something.

View 3 Replies View RelatedHi,
I have a trigger that fires on update, populating a varchar field [ExampleDate_Str] with the dd/mm/yy format of the inserted datetime field [ExampleDate]. It works, but I don't want to rewrite it for the thousands of datetime fields in hundreds of tables in my db. So I am looking for a way to do something like this in a trigger -
for each column in triggered tableset @ColName = (the column name)if datatype(@ColName) = datetimeset @ColName + "_Str" = convert(varchar(8),ExampleDate,3)next
Obviously the above doesn't work in SQL or indeed any other language yet invented - is it possible to make it so that it does, and if so, how? The main points are to read the column name into a variable, check the datatype, and modify the column named @ColName + "_Str".
Thanks...
Hi Everybody,
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.
tks in advance,

I just need help with being able to store values in my declared variables for insert into another table. Thanks in advance for everyones help.
Use database_testing

DROP TRIGGER Trigger_Name
GO
CREATE TRIGGER Trigger_Name
ON [trigger_table] FOR INSERT
AS
Declare @resource_id int = inserted.resource

@date_logged (datetime) = inserted.creation_date
@created varchar(100) = inserted.username
Insert into table_A (resource_id, resource_type, date_created, created_by)
values (resource_id,type, date_logged, created)
Fairly new to triggers and stored procedures and so far I haven't had to pass any variables or even call an SP from a trigger. The problem I have is to pass a 'callid' variable from an insert trigger to a stored procedure.
The SP is to delete any rows that already exist that contain the passed 'callid' and then insert the new inserted data (using variables again hopefully).
Is this at all possible and if so what is the syntax for passing the variable from the trigger and then reading it into the stored procedure ?
TIA

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.
Hello all ,I tried to insert text datatype by using storedprocedures but I couldn't do it ,anyone has any clue or idea ,sincerely youres
View 3 Replies View RelatedOK, 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?
Any help greatly appreciated!

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.
Code:
SELECT id FROM leads WHERE DATALENGTH(dsc)=0

Now, what does THIS mean??
"Data types text and text are incompatible in the equal to operator"
(I'm doing a CAST() to convert a quoted string to
Text, which is the data type of a column)
