I am trying to write a generic stored procedure to return the data type of a given col in a given table in any database.
I would like to place this sp in master.
input parms are @TableName sysname and @ColName sysname
ouput parm is @data_type varchar(128)
set @data_type=''
select @data_type = data_type from information_schema.columns where table_name = @TableName and column_name = @ColName
when debugging this I always get 0 rows (@data_type remains '')
I have a thought that I can add an input parm for the database, say @DbName sysname
But I am having trouble updating the select stmt to be something like
...from @DbName +'.' + information_schema.columns.
I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:
at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.
So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:
The following columns cannot be mapped: [Department, DEP_CLEGALCODE] One or more columns do not have supported data types, or their data types do not match.
The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.
The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination
I've been writing this stuff for a while, and can't seem to come to the conclusion of how I should be retrieving data and assigning this data to variables.
Since i'm using SQL Server, I'm convinced that I should be using the datareaders GetSqlDouble (or whatever) function, but this would mean i need my local variables to be one of the SQL types. The problem with that is, that there will have to be lots of conversions done by me to be able to use a SQL type in my application.
For instance, I have a class where i'm retrieving dates. In order to retrieve them correctly (Null values included), I need to retrieve them with GetSqlDateTime(), then when it comes time to display the date in a table, i must first check for nulls, then convert to a string. This seems to be very cumbersome. Would I be better off just using GetDateTime(), and the .ToString method, and ignoring Sql Types all together?
so, basically, how are you guys using your sql server data? with the supplied sql types, and doing all of the post-processing work manually? I feel like i'm having trouble conveying my issue...hopefully someone knows what i mean....i'd just like some direction to save trouble in the long run, since i feel like there's got to be a better way...
Is there a way to change the default data type in SQL Server? If I import a database into SQL Server it makes every non-numeric field a nvarchar field. Is there a way to change this so that these fields would be varchar or char by default? I cannot find any way to redo these as a batch/group update and have to modify every single field manually. Any insights greatly appreciated.
I trust you'll bear with an SQL Server newbie with what may seem a rather inane request. I am designing a web app in Web Designer 2005 Express with SQL Server Express. Unfortunately, I'm finding a little confusing with some of the data types when designing tables. I have tried to find information on the various Microsoft sites (general site, MSDN, here) and while I found one document that had a table comparing data types in different implementations of SQL, it wasn't at all helpful. Most of my confusion is with the various string and char types; the numeric types seem pretty straight forward for the most part. However, it might be helpful to know the difference between money and smallmoney/datetime and smalldatetime, particularly space/size information and formatting options (unless the latter is up to the interface). It would also be helpful to know which string/char types correspond to any counterparts they might have in, for instance, Access (with which I am already quite exprienced). Or any particular quirks or idiosyncracies they might have. I don't expect anyone to write a full tutorial, but if someone could point me in the direction of a good online doc, it would be most appreciated. You might well ask, why not use Access databases? I would answer...I like to learn new stuff! Thanks much.
Hi, Can anybody give me some information on Table data types of SQL2K. How and where can it be used. Does it make the queries faster, in case there are many users using ? Please could anybody give me these details, to make me decide whether I can use it or not ?
We have a query that joins column A int which is an int onto column B with contains only int's but was created as a varchar and can't be changed to an int at the moment.
Casting column a as a varchar in the ON of the join to left join seems to void the index altogether and the query just runs for every.
We are talking a few hundred million rows of data in each table.
Temp solution is select into a #Hash table as correct data type and index then use the #Hash table in the join.
I need to create a view of a sql table, but change the data types. I knowthe syntax below is not correct, and can't figure out if it is wrong or ifyou just can't do this. I have only created views before with the same datatype.CREATE VIEW F0005New(DRKY nchar(3), DRDL01 nchar(30))INSERT (SELECT rtrim(F0005.DRKY), F0005.DRDL01FROM F0005 AS F0005WHERE DRSY = '41' AND DRRT = 'S1')Thanks!!
Hi Can anyone point me to a document somewhere that shows a mapping ofSQL Server 2000 datatypes to C datatypes? I am writing some extendedstored procedures which need to be able to process pretty much anydata type, so I want to make sure I am taking them from SRVPROC andstoring them in the correct C data type.Thanks,Bruce
Hi,Can anybody tell me if it is possible to return a table data type (asopposed to a temporary table) from a stored procedure.I am currently studying for 70-229 using the Thomas Moore book but itdoesn't really make it clear, as the text suggests you can't returnthem but some of his sample questions suggest you can.I can't make it work in Query Analyser so I am assuming that you can'treturn them. Is that correct?Thanks in advance for any help,Simon.
I´m building an aplication with VB.net and SQL Server 9, but in the future it will be compatible with PostgreSQL (by another developer), so my question is, if anyone knows what "data types" in SQL Server 9 i must use to maintain compatibility with PostgreSQL, so that when the time come for the conversion i don t have to chage the "Data Types" on each table.
We are developing customer support application. We will have so many customers after launching this product. But my problem is how will i store data of all these customers in SQL Server. Please suggest me.
I need to populate some SqlParameter but I temporarily need to populate with a default value for the data type in question. Of course I can work them out, but I was wondering if there is already a way of doing this, from the .Net Classes or from SQL Server but without making a trip to the DB.
i have created asp.net page, one feild of this page text area. when i insert some text through this page in "text feild" of SQL server on few words of this feild cut and inserted to text feild of SQL server but all text that i have written in text area feild.
can u please help me how to handle so that i can all text in text feild of SQL server data type text/next.
I have a simple Integration Services project and the problem is that decimal fields are importing as real (I'm loosing the digits behind the decimal point).
The project contains a data flow task importing a flat file (.csv) to an SQL Server destination. My .csv file has two decimal type fields. Example:
Field 1: 12345.67
Field 2: .123456
My database table that I'm importing to has two fields. The only way that I can get this data to import is to define the fields as "float" in both the text file and database table. I want the database table fields to be defined as decimal or numeric, not float:
Field 1: decimal(7,2)
Field 2: decimal(6,6)
When all fields are defined as decimal (in both the flat file and database file), I get the following results:
Field 1: 12345.00
Field 2: .000000
How does one import decimal data from a flat file (.csv)?
I think I may have figured out the solution to my recent conundrum with SQL Server 2000 that had me stressed and depressed over the last couple of days. In a nutshell, after a HotFix was installed on a SQL2K database server I have space on, I was unable to perform INSERT or UPDATE queries on database table of type TEXT, when trying to either create or modify records with more than 4,000 characters of data. While it was frustrating as heck, it seemed too rigid to be random, so I did some snooping.
The HotFix was intended to solve a known problem of not being able to run UPDATEs against TEXT fields, but in so doing, caused another headache entirely: http://support.microsoft.com/?kbid=839523
Apparently this is a semi-known problem, in that a certain HotFix forces SQL Server 2000 to be a lot more stringent in requiring explicit declaration of data types and data lengths for parameters in stored procedure. In my client code, I was initially using the overloaded constructor of the SqlParameter object that took as arguments only the parameter name and a value, without specifying a value from the SQLDBType enumeration or length of the parameter (which in my case, needs to be TEXT and 16 (or 2147483647), respectively):
It appears that after the HotFix is installed, if the client doesn’t syntactically set the type and length of data for a parameter, SQL Server and/or .NET will default to a type of NVARCHAR, which has the 4,000-character limit. This all makes sense. I’m going to now need to modify the code to straight out declare what’s going in the SPROC:
It’s a minor change, and it sucks that I have to make it after the code had worked flawlessly over several thousands executions over several months, but c’est la vie! Better thay than have to rebuild my DB from scratch or switch to a new server. Changing the client code evidently is the only known fix at this time: http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3b827366
I am trying to find a reference for a client that lists the fields available to be substituted into a data driven subscription from the query, along with the expected data types.  For example, the field on whether or not to include a link to the report seems to be expecting a bit data type.I have searched and can't seem to find anything.  I guess I could walk through the interface and try different data types, but if  a list exists, that would be better.Â
While run time these values are lets suppose @SSN = '999-000-000' & @State='ABC'
Now the Result is displayed with the state data Like 'AB' only.
Output: 1 999-000-000 AB
instead it should give system generated error.
Here I have 2 Questions: 1. Why it is taking 1st 2 Charecters? 2. Why it does not have any system generated for length?
I can do validation with Length function for these 2 variables however if have 100 variables then it should not feasible case. So, what is the reason behind?Â
I'm in the process of converting a rather huge VSAM database into a set of SQL tables. I am using the same data names from the mainframe (like XDB-NAME to RDB-NAME). I load the files using Import Export Data and it makes the tables with such column names as col001, col002, col003, etc... and always sets the data types to varchr(255). And I have to cut and paste the data names from the manframe side to the server side (and the data types to.) So, is there an easier way to do this? Or am I doomed to cut-n-paste my days away... Thanks for any help.
Is it possible to easily copy data from one table to another if the data types don't match. I know you can do a INSERT INTO table1(col1,col2) SELECT (col2,col7) FROM table2 if the data types match but is there a way to do this if they don't. I'm not trying to copy date times into bit fields or anything. I just have an old table that I built when I really didn't know what I was doing now I at leastthink I have a better understanding of what data types to use, so I was wanting to move the data in the orignal table to my new one. Most of the fields in the olddatabase are text datatypes and the new database is nvarchar(50) data types. Thanks for any suggestions.
I have a really dumb question regarding SQL data types. I have a couple columns in a table that are specified as MONEY. These columns are being read from my web app and displayed on the website for reference when filling in other information.
My problem is that when it is displayed on the website it give four decimal places instead of two. For example I want it to report $33,000.29 but what is actually displayed is $33,000.2965.
How can I set up either SQL or my web app so that it only displays the two decimal places? I've looked into changing the datatype already but SMALLMONEY and MONEY have the same type of decimal values.
I am looking for a chart of SQL Server data types and information about them, such as usage, constraints, etc. Could anyone point me in the right direction?
I'm just getting used to using SQL 7 Database and am looking for some recommendations on what DATA TYPES to use when designing tables.
The site I am working on now uses cold fusion to enter, update, and insert mainly text and articles. Now the problem with the articles is that some of them are pretty big. And when inserting or updating them, if they go over the limit of characters I get an error.
I know in access I used to use the data type "MEMO" and be able to put a large piece of info in that field.
What's the equivalent for SQL server databe?
What are the most used/common or recommended data types that should be used when putting tables together?
hi, i'm trying to build an online forum using sql server 2000 and coldfusion mx.
could anybody help me as to what datatypes i should use for my database fields?
i'll be using 2 simple tables to start with, ie TOPICS and POSTS. each will contain fairly basic information such as name of poster, time, data, title, message etc.
any help would be greatly appreciated. thanx, zaffi.
Which data type do I need to assign to my field to let users enter characters such as +=-_| etc....pretty much every single character from a standard keyboard....
I am pretty new with SQL and was dabbling in a test database that is linked with a software application.
I made a change to a table - Lets call this (Table1). Table1 has a multiple columns.
Column1 is defined as numeric(9) Column2 is defined as varchar(20)
In this case, I wanted to make all values in Column2 = Column1 that did not have a value defined so I ran the following query:
update Table1 set Column2 = Column1 where Column2 = ''
This took effect but the particular software application doesn't recognize these values because they are the wrong data type.
How can I convert all data in a column to varchar(20) if it is another data type (i.e. in this case numeric(9))?
I've tried in Enterprise manager to redesign the table and adjusted the length to 21 and then back and saved it but this did not work. I was looking at Convert and Cast functions but don't know how to write one to accomplish what I need to do here.
Half of the data in Column2 is varchar(20) and half is numeric(9). I want all to be varchar(20).
