Transact SQL :: Determining Procedure Variable Type?
May 12, 2015I am building as Search page whereby a user passes in a variable and depending on the variable type, different results will come back ...if the search criteria is '123 somewhere' it would be a string and we would search the address field. If the search criteria is '123' i want to search the address field as well as the id field.that being said, in TSQL is there a way to determine if the variable coming in is a string or an int?
View 3 Replies View RelatedWhat Is This Box Type Character For A Blank Space In SQL Server?
Mar 8, 2007Hi,
I am using DTS for importing a table from FileMaker Pro (a database application) to SQL Server 2000. The problem is that everything gets imported correctly but in some values, it shows a box type character for a blank space. It does not happen for all the blank spaces. Because of this, that value is cannot be checked in the WHERE clause until I use a LIKE and % for that blank space.
I copied the value and pasted in Notepad, it only shows a blank space. What is this character?
Can someone help...
Thanks,

View 5 Replies View RelatedWhen Changing To Type Text From Nvarchar, The 255 Character Limit Is Maintained?
Jul 23, 2005Hi - I am changing a field from type nvarchar to type text, given thatI need to store strings longer than 255 characters. To do this Ichange the data type in SQL Server, then I change the parameter code inthe calling procedure, as per below:cmd.Parameters.Append(cmd.CreateParameter("@title", adVarWChar,adParamInput, 255, title));becomes:cmd.Parameters.Append(cmd.CreateParameter("@title", adLongVarWChar,adParamInput, 1073741823, title));However, when I do this, for some reason, the field is still limited to255 characters - when I try to update the field with 256 characters,the error 'Application uses a value of the wrong type for the currentoperation.' occurs.Why is this? I've checked that the correct data is contained in theparameter. When I look at the data in the database, the column inquestion shows the content, whereas the next column, which has alwaysbeen of type text, shows '<LongText>' - does this mean anything? Do Ineed to do something special to convert the column from nvarchar totext?Many thanks,Iain

Conversion Failed When Converting Character String To Smalldatetime Data Type
Oct 3, 2007I am running the following query:
select distinct hqvend, hqvprd,fprod,idesc,ilead,sum(cast(fqty as int) )as fqty, (cast(hqvend as varchar(5))+'/'+ltrim(rtrim(fprod))+'/'+cast(ilead as varchar(3))) as Keydata,'L1/'+rtrim(fprod) as LocPartno from tblkfpl01 inner join hqtl01 on (fprod=hqprod) inner join iiml01 on (hqvend=ivend and hqprod=iprod) where cast(cast(hqeff as varchar(8)) as smalldatetime) <= (Select CONVERT(varchar(8), getdate(), 1)) and cast(HQDIS as varchar(8)) >= (Select CONVERT(varchar(8), getdate(), 1)) and hqvend like '134%' group by hqvend,fprod,hqvprd,idesc,ilead order by hqvend,fprod
The bold sections are giving me the error message. The query works as written above, butis only evaluating on one date, contained in hqeff. However, when I try to modify the second date, HQDIS, by casting it the same way as the one before it:
select distinct hqvend, hqvprd,fprod,idesc,ilead,sum(cast(fqty as int) )as fqty, (cast(hqvend as varchar(5))+'/'+ltrim(rtrim(fprod))+'/'+cast(ilead as varchar(3))) as Keydata,'L1/'+rtrim(fprod) as LocPartno from tblkfpl01 inner join hqtl01 on (fprod=hqprod) inner join iiml01 on (hqvend=ivend and hqprod=iprod) where cast(cast(hqeff as varchar(8)) as smalldatetime) <= (Select CONVERT(varchar(8), getdate(), 1)) and cast(cast(HQDIS as varchar(8)) as smalldatetime) >= (Select CONVERT(varchar(8), getdate(), 1)) and hqvend like '134%' group by hqvend,fprod,hqvprd,idesc,ilead order by hqvend,fprod
I get the error message. I need to select based on both dates (hqeff AND HQDIS), but cannot seem to be able to it.... Both fields are of type Dedimal, with a length of 8, and dates stored in them look like: 20071003 (YYYYMMDD).

T-SQL (SS2K8) :: Conversion Failed When Converting Character String To Small Date-time Data Type

Read Chinese Character From SQL(SQL Server 2005) Database Table Column And Display Chinese Character
Feb 1, 2008Hi!
I have a table like this below and it doesn't only contain English Names but it also contain Chinese Name.
CREATE TABLE Names
(FirstName NVARCHAR (50),
LastName NVARCHAR (50));
I tried to view the column using SQL Query Analyzer, It didn't display Chinese Character.
I know that SQL Server 2005 is using UCS-2 Encoding and Chinese Character uses Double Byte Character Set (DBCS) Encoding.
I want to read the FirstName and LastName columns and display in Window Form Data Grid and ASP.NET Grid View.
I tried to use this code below and it didn't work. It convert some of the English Name to Chinese Character and it display the chinese character and some still in the original unreadable characters.
Does anybody know how to read those character from SQL Table and display the correct Chinese Character without converting the English Name into Chinese also?
Thanks

Determining Unique Children
Nov 17, 2005Hi,
I need to be able to identify if a parent has the same child names as another parent.
Have a look at my data (in pic)
Can you think of a SELECT that will count for each parent, the number of other parents including themselves with all the same children's names?
So you would get something like:
Bob | 2
Bill | 1
Glen | 2
thanks,

Determining Database Size
May 9, 2008Forgive the easy question but I'm afraid it might be also a trick question and I'd like to hear the experts' opinion. I am using SQL Server 2005 Express edition and I know the limitation is 4GB per database. So far none of my users is anywhere near the limit but I have to be prepared for when that day finally comes. As it stands, they use a single database through a program so I have full control over it. There are no fancy backup programs on the system so no fancy recovery models and automatic shrinking can be done - data is only inserted in that database.
My question is simply how can I determine programmatically (I use ADO.Net but it can execute SQL commands just fine) the size of the database as it relates to the limitation? That is, I don't know whether it is the amount of data stored - with or without overhead, or it is simply the size of the *.mdf file (maybe together with the *.ldf file), or whether the 4GB is 4 billion bytes or 2^32 bytes - I just want the same method that the SQL Server is using so that, for example, I can bring up a warning at 90% full and lock out the user at 99% full.
I'd appreciate any insights.

Determining A Range Of Values
Mar 29, 2012suppose you have a large table with 2 columns
create table tick
(
ID bigint identity (1,1) primary key not null
, price money not null
)
and I want to know 3 things
Starting with ID = 1 through ID = (last)
give me the low and high price (that satisfies the below WHERE clause), and the last ID
WHERE high price - low price = 0.10
and the last ID (last) is the minimum ID to satisfy: high price - low price = 0.10
So the last ID will coincide with the record containing either the low or high price, the problem is you don't know which record in that range has the corresponding high/low price, it could be the first record or the 10,000th record.
I am thinking I need to create two summary tables, maybe calculate the min(ID) that goes down 0.01 then the min(ID) that goes down 0.02, etc...
Then calculate the min(ID) that goes up 0.01 then up 0.02, etc..finally join against these two summary tables to figure out which combination of downSummary and upSummary have a difference of 0.10.
Determining If SQL Statement Is A Query
Jul 27, 2007Hi,
I have a C# server application which clients can send arbitrary SQL statements to. These can be absolutely anything - creating tables/views, selecting from tables/views, inserts, updates, deletes, you name it.
There are two return parameters from the server method which executes the SQL - a results set containing the data, and a count of the rows that were updated - (either one or the other should be populated depending on the type of command sent to it). To deal with this, what I planned on doing was (pseudocode follows..):
try
{
reader = OpenReaderCursor(statement)
}
catch
{
updatedCount = ExecuteNonQueryCommand(statement)
}
Unfortunately this doesn't really work, as OpenReaderCursor is able to execute Non Queries (eg. UPDATE/INSERT/DELETEs etc) but doesn't give me a row count, and trying the other way round, ExecuteNonQueryCommand is happy to execute SELECT statements, but I can't then of course return a results set as I don't have access to it.
My question then, if you will excuse the waffle above, is "Is there a simple way of determining if a string containing an SQL statement is a query?" - or will I have to come up with some way of dealing with this in my application code?
Please don't slate the design (ideally I would have two methods on the server, one for queries which returns results and the other for nonqueries which returns an updatecount) but there's nothing I can do, this is how it must be done (the interface was defined long long ago)
Thanks for your time, all ideas appreciated

Any help would be greatly appreciated.

Feb 1, 2006Hi,
can anyone tell me if there is a way to determine with SMO or RMO if a database is a subscriber when using merge replication. If only have the Server and database at this point too!!
I want to provide a small app that creates a merge publication but only if the database isn't a subscriber.
Thanks for your help
