SQL Server 2008 :: How To Get The Column Type And Length
Feb 23, 2015
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%'
'The value you entered is not consistent with the data type or length of the column'
when trying to enter data into a feild, the feild type is char and the length is 100 i'm entering text 3 words long but no where near a 100 characters long any one know why this is happening?
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.
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?
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 ?
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.

Hello Friends, I am working on a web application and using Sql Server 2005 as a Databasew. I want to define a variable with the datatype as defined in the database. Let me give an example. In my web say there is a field "First Name" and for that I had created a TextBox "txtFirstName" in code behind to get this value I have defined a variable String getFirstName; Now this variable has to be stored into the table "Person" into the column "FirstName" which is of type "nvarchar" and having length "20" So I want to get this length programatically so that I can assign this number (20) to the maxlength property of the textbox "txtFirstName" so that in future if the legth of the database column changes it should no be needed to change in code also. Caqn it be done? If yes please let me know. Thanks & RegardsGirish Nehte
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.
There are some more columns with more 'nvarchar' (max) and other INT data types. Anyway, I know a page is 8K size. How do I find out how much space does A ROW takes with above datatypes? If users add 5000 Rows per day, how do I figure out how much size the table will increase?
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')
I'm trying to store the output of my stored procedure into a temp table, which takes Table Type as Input.
CREATE TYPE [dbo].[Employee] AS TABLE( [Field] [varchar](50) NULL, [Criteria] [varchar](50) NULL, [Value] [varchar](50) NULL ) declare @Employee dbo.Employee insert into @Employee values(N'Salary',N'is greater than',N'3520')
DECLARE @sql NVARCHAR(MAX)
SET @sql = 'SELECT * FROM OPENROWSET(''SQLNCLI'',''Server=localhost;Trusted_Connection=yes;'',''EXEC dbo.uspGetEmployee ' + @Employee + ')'
I need to create a stored procedure which uses output of the above stored procedure. Hence, I don't want to put declare and insert into OPENROWSET as I get those values as parameter to the new procedure.
Is there a good way to add columns to a table type?
I built several procs which make use of table-valued-parameters, and they work pretty nicely, until I need them to accept additional columns. Then I have to drop all the procs that use them, alter the types, and rebuild all the procedures, which is a huge pain in the rear.
Is there any good way (built in, or custom) to alter the def of a table type that's used as a parameter to multiple stored procedures?
I'm using the SQL below to work out recruitment figures. The query works well, but I now need to build this query into a DotNet application as a webpage. I therefore need to declare and manipulate the values such as 'Total', 'Jan' to 'Dec' and 'YearRecruited' in order to write these values into my chosen data control. I therefore need to know the datatypes of these calculated values.
Total I think is straightforward as DNAScreeningID is an int datatype. But what about the others?
SELECT YEAR(SamplingDate) AS YearRecruited,
COUNT(CASE WHEN month(SamplingDate) = 1 THEN DNAScreeningID END) AS 'Jan', COUNT(CASE WHEN month(SamplingDate) = 2 THEN DNAScreeningID END) AS 'Feb', COUNT(CASE WHEN month(SamplingDate) = 3 THEN DNAScreeningID END) AS 'Mar', COUNT(CASE WHEN month(SamplingDate) = 4 THEN DNAScreeningID END) AS 'Apr',
I've never worked with the XML data type in SQL Server, although I know its been there for a few iterations of SQL SErver. Now I've got a situation in which it might store some configuration data as XML, since that's the way it comes. (We had thought about storing the data in a VARCHAR(MAX) field.)
The first question is does the XML data type have a size limitation? For example do you do something like:
ConfigFile XML(1000) NULL
Or is it just something like this:
ConfigFile XML NULL
The second question is persisting the data to a file. As the name I choose for the variable suggests, we want to save the data from a configuration file into a SQL Server database. How do we go about doing that? We'll be developing a C# application, it will read and write the data both from the SQL table and the user's local HD.
Should data type money allow nulls? Are there valid arguments both pro and con?
Yes, there is the age-old question regarding how one might interpret a NULL found in any column - does it mean the amount is not known or that the amount is zero (in the case of a numeric type)? You get the drift...
Other than that, though - are there any practical considerations an old data hound ought to be aware of?
I am getting an error importing a csv file both using SSIS and SSMS. The csv is comma delimited with quotes for text qualifiers. The file gets partially loaded and then gives me an error stating The column delimiter for column "MyColumn" was not found. In SSIS it gives me the data row which is apparently causing the problem but when I look at the file in a text editor at the specific row identified the file has the comma delimiter and it looks fine. I am using SQL Server 2008.
SELECT P.Publication ,P.Publication_type ,S.Subscriber_ID ,S.Update_Mode FROM MSPublications P INNER JOIN MSSubscriptions S ON P.Publication_ID = S.Publication_ID
give me publication_type=0. So it is transactional replication but how do we know that is pull or push?
I am having an issue fetching Chinese characters in a XML data type. It return questions mark (?).
Below is the sample script.
DECLARE @XMLVAR XML SET @XMLVAR = '<?xml version="1.0"?> <POLICY_SEARCH xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <NAME>QA*保险1</NAME><NUMBER /></POLICY_SEARCH>'
SELECTI.xmlParam.query('./NAME').value('.','NVARCHAR(25)') NAME ,I.xmlParam.query('./NUMBER').value('.','NVARCHAR(25)') NUMBER FROM@XMLVAR.nodes('POLICY_SEARCH') AS I(xmlParam)
I am getting an error when running this query in SSRS- "an expression of non-boolean type specified in a context where a condition is expected , near ',' " on the following query in the WHERE clause section.
SELECT MG_BL_ITINERARY.ETA_DT, MG_BL_ITINERARY.TO_LOCATION_CD FROM MG_BL_ITINERARY
[code]...
what I need to change in the WHERE clause to rectify this error ?
I have problem to execute query with interval date.
If try this query I don't have problem and the output is correct:
SELECT * FROM dotable WHERE dotableDate BETWEEN CONVERT (datetime, '01/01/2015', 121) AND CONVERT (datetime, '09/01/2015', 121);Instead if try this I have error: SELECT * FROM dotable WHERE dotableDate BETWEEN CONVERT (datetime, '25/01/2015', 121) AND CONVERT (datetime, '28/01/2015', 121);

Not seeing the Review Data Type Mapping Screen in SQL Server Import and Export Wizard?
Is there only a certain version where that screen shows up?
I am trying to import data from an MS Access application to SQL Server and all of the connections are good, but some of the data isn't and if I let it migrate using this tool it crashes on the bad data and there is no data that migrates. The Review Data Type Mapping screen will allow me to bypass the records in error and load the rest. however, I can;t do that if I cannot see the screen.
