Mapping A String Field To Boolean Output In SELECT Clause
Oct 18, 2006
Hello,
I am facing a problem in a SELECT clause which i cannot solve.
In my SQL table ("myTable") i have a few columns ("Column1", "Column2", "TypeColumn"). When I select different columns of the table, instead of getting the value of TypeColumn, i would like to get a boolean indicating whether its value is a certain string or not.
For example, the TypeColumn accepts only a number of selected strings: "AAA", "BBB", "CCC".
when i do a select query on the table, instead of asking for TypeColumn i would like to ask a boolean value of 1 if TypeColumn is "AAA" and 0 if TypeColumn is "BBB" or "CCC". Also, i would like to make this query while I am also fetching the other columns. And i would like to use one query to get all that. I thought something like thsi would work:
SELECT Column1 AS Col1, Column2 AS Col2, IF(TypeColumn = "AAA", 1, 0) AS Col3
FROM myTable
but this doesn't work in SQL 2005!
Is it possible to do something similar in SQL 2005 using one query only? i am trying to avoid multiple queries for this.
I am currently trying to find a way in which I can determine if a column in a Select clause is Japanese. The column currently supports English and Japanese Kanjis and other kanas. Is there a way to determine if this column is not English or if it is Japanese without physically looking at it.?
I'm looking for some good hints and tips for reprogrammin an old VB module I just found.
Basically what it does, is receive an input parameter (an int), does a select [name row] from Names where Name_id = [input parameter] and turns this into a string if multiplenames appear.
E.g. result set: John, Josh, Jock turns it into string "John Josh Jock".
So its piece of cake creating a stored procedure selecting data on the base of an input parameter. Select X from Y where Z = @input... the trick is, I don't know how to do arrays in TSQL as in VB.
In the VB edition I create an array, load the names into it, I do a count on how many row the select returns and then a simple for... next adding the names to the string.
Any good examples on how to do this in a sql-server stored proc?
Thanks,
Trin
P.S. This is what I have pieced together this far:
DECLARE medlemcursor CURSOR FOR SELECT [MCPS Kode] FROM DW.dbo.names(NOLOCK) WHERE number = @number
OPEN medlemcursor
FETCH NEXT FROM medlemcursor INTO @tempinstt WHILE (@@FETCH_STATUS <> -1) BEGIN SET @instrument = @instrument + @tempinstt + '-' FETCH NEXT FROM medlemcursor INTO @tempinstt END
CLOSE medlemcursor DEALLOCATE medlemcursor
SELECT @instrument GO
Just doesn't seem to work, returns NULL, even though I've checked that the cursor SELECT statement actually returns data,
I understand that Multi-Select Parameters are converted behind the scenes to an In Clause when a report is executed. The problem that I have is that my multi-select string parameter is turned into an in claused filled with nvarchar/unicode expressions like:
Where columnName in (N'Value1', N'Value2', N'Value3'...)
This nvarchar / unicode expression takes what is already a fairly slow-performing construct and just drives it into the ground. When I capture my query with Profiler (so I can see the In Clause that is being built), I can run it in Management Studio and see the execution plan. Using N'Values' instead of just 'Value1', 'Value2','Value3' causes the query performance to drop from 40 seconds to two minutes and 40 seconds. It's horrible. How can I make it stop!!!?
Is there any way to force the query-rewriting process in Reporting Services to just use plain-old, varchar text values instead of forcing each value in the list to be converted on the fly to an Nvarchar value like this? The column from which I am pulling values for the parameter and the column that I am filtering are both just plain varchar.
I'm trying to create a WHERE clause that will have different results depending on a parameter that is entered. For example, if you put in a number, it will only calculate the rows where the column ID matches that number. However, if you put in 0, which doesn't exist in that column ID, it will instead calculate all the data in the table.
So the below would be a very basic idea of what I'm trying to do, but I'm not sure how to do it with proper syntax.
I am working on SSIS package that gets data from SQL 2005 Database and writes that to a flat file. But I need to write the count of records as part of the header.
Here is what i am trying:
The OLE DB Source is calling a stored procedure and returning two things i.e. a resultset and an output parameter. The data access mode is SQL Command.
Code SnippetEXEC [Get_logins] ?, ?, ? OUTPUT
In the Set Query Parameters dialogbox, all the three patameters are mapped to three different user variables.
What is happening is that the user variable that is mapped to output parameter is never updated. The header property expression is written as follows
I tried to watch the variable in watch window but to no avail. Any guidance if it is bug or I am missing some thing? Any thoughts, how can I accomplish this? I have also tried adding Row Count Transformation but its variable has the same behaviour. If I set the value of @LoginCount variable to some value, this initially set value is successfully written to the file header.
I have a gridview connected to a sqldatasource, and it works pretty good. It gives me the subsets of the information that I need. But, I really want to let them choose all the companies and/or any status. What's the best way to get all the values in the gridview...besides removing the filters :) I thought the company would be easy, I'd just set the selected value to blank "", and then it'd get them all....but that's not working. And, for the boolean, I have no idea to get the value without having a separate query. (tabs_done=@tabsdone) and (company like '%' + @company + '%')1 <asp:DropDownList ID="drpdwnProcessingStatus" runat="server"> 2 <asp:ListItem Value="0">Open</asp:ListItem> 3 <asp:ListItem Value="1">Completed</asp:ListItem> 4 </asp:DropDownList> 5 6 7 <asp:DropDownList ID="drpdwnCompany" runat="server"> 8 <asp:ListItem Value="">All</asp:ListItem> 9 <asp:ListItem Value="cur">Cur District</asp:ListItem> 10 <asp:ListItem Value="jho">Jho District</asp:ListItem> 11 <asp:ListItem Value="sea">Sea District</asp:ListItem> 12 <asp:ListItem Value="san">Net District</asp:ListItem> 13 <asp:ListItem Value="sr">Research District</asp:ListItem> 14 </asp:DropDownList> 15 16 17 <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:HRFormsConnectionString %>" 18 SelectCommand="SELECT DISTINCT [id], [lastname], [company] FROM [hr_term] hr where (tabs_done=@tabsdone) and (company like '%' + @company + '%')"> 19 <SelectParameters> 20 <asp:ControlParameter ControlID="drpdwnProcessingStatus" DefaultValue="0" Name="tabsdone" PropertyName="SelectedValue" /> 21 <asp:ControlParameter ControlID="drpdwnCompany" DefaultValue="" Name="company" PropertyName="SelectedValue" /> 22 </SelectParameters> 23 </asp:SqlDataSource> 24
I have used Data Flow component that refers to named query of data source view. It is a OLE DB source.
The SQL Command property of data flow component shows SELECT * FROM Tablename as I defiend in named query. I have modified the query to accept a parameter as SELECT * FROM Tablename WHERE Status = ?
Now I need to pass the package variable to this parameter. How to I pass using ParameterMapping property?. What is correct way of passing the parameter mapping ? I tried with @[TestNS:tatus] variable. But it throws error The parameter mapping string is not in the correct format.
Hi all,How do you select and check a boolean value within a stored procedure? I don't know if this is correct or not:DECLARE @CheckStatus bitSELECT @CheckStatus = PREF_STATUS FROM tblPrefsWHERE [PREF_ID] = @PREF_IDIF (@CheckStatus IS FALSE) -- DO SOMETHINGIF (@CheckStatus IS TRUE) -- DO SOMETHING But I'm not sure if what I've used (IS FALSE/TRUE) is the correct way? "PREF_STATUS" is a bit column in my table.Thanks.
Hi,I have boolean values in a table for ex. Federation. And I want toselect followingSelect 'Insert into' + member + 'test' as test1from federationThen I get error messageServer: Msg 403, Level 16, State 1, Line 1Invalid operator for data type. Operator equals add, type equals bit.Someone can help me out of it.Thanks an advance- Loi -
Example, suppose you have these 2 tables(NOTE: My example is totally different, but I'm simply trying to setupthe a simpler version, so excuse the bad design; not the point here)CarsSold {CarsSoldID int (primary key)MonthID intDealershipID intNumberCarsSold int}Dealership {DealershipID int, (primary key)SalesTax decimal}so you may have many delearships selling cars the same month, and youwanted a report to sum up totals of all dealerships per month.select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',sum(cs.NumberCarsSold) * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDMy question is, is there a way to achieve something like this:select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',TotalCarsSoldInMonth * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDNotice the only difference is the 3rd column in the select. Myparticular query is performing some crazy math and the only way I knowof how to get it to work is to copy and past the logic which isgetting out way out of hand...Thanks,Dave
I'm copying records from table A to Table B. On "insert" being successful I want to delete the copied records from table A. I want to use one single transaction. Could I use OUTPUT to delete all records in table A which key matches the ones on "inserted" ?. I believe it could be possible but I have tried several ways without any luck.
INSERT INTO Table A (Field 1, Field 2) OUTPUT (DELETE Table B WHERE Key = (SELECT Key FROM Inserted)) SELECT (Field1, Field 2) FROM TABLE B
I have a nasty situation in SQL Server 7.0. I have a table, in whichone column contains a string-delimited list of IDs pointing to anothertable, called "Ratings" (Ratings is small, containing less than tenvalues, but is subject to change.) For example:[ratingID/descr]1/Bronze2/Silver3/Gold4/PlatinumWhen I record rows in my table, they look something like this:[uniqueid/ratingIDs/etc...]1/2, 4/...2/null/...3/1, 2, 3/...My dilemma is that I can't efficiently read rows in my table, match thestring of ratingIDs with the values in the Ratings table, and returnthat in a reasonable fashion to my jsp. My current stored proceduredoes the following:1) Query my table with the specified criteria, returning ratingIDs as acolumn2) Split the tokens in ratingIDs into a table3) Join this small table with the Ratings table4) Use a CURSOR to iterate through the rows and append it to a string5) Return the string.My query then returns...1/"Silver, Platinum"2/""3/"Bronze, Silver, Gold"And is easy to output.This is super SLOW! Queries on ~100 rows that took <1 sec now take 12secs. Should I:a) Create a junction table to store the IDs initially (I didn't thinkthis would be necessary because the Ratings table has so few values)b) Create a stored procedure that does a "SELECT * FROM Ratings," putthe ratings in a hashtable/map, and match the values up in Java, sinceJava is better for string manipulation?c) Search for alternate SQL syntax, although I don't believe there isanything useful for this problem pre-SQL Server 2005.Thanks!Adam
Insert into Table1 (col1, col2) Output Inserted.col1, inserted.col2,MyTable.C3, MyTable.C4 into Table2 select C1,C2 from MyTable
Now the Output statement retrives only the Inserted.col1, inserted.col2 values, But I want to add MyTable.C3, MyTable.C4 values from the table <MyTable>
In the past when inserting a record into a table with an identity column, to return the new identity value I used one of SCOPE_IDENTITY, IDENT_CURRENT, and @@IDENTITY.
Question: will this sql 2005 approach also provide the newly added identity value?
insert into TestTable -- ID column of testtable is an Identity field
output inserted.id, inserted.col1 into @insertedRecords
Insert into Table1 (col1, col2) Output Inserted.col1, inserted.col2,MyTable.C3, MyTable.C4 into Table2
select C1,C2 from MyTable
Now the Output statement retrives only the Inserted.col1, inserted.col2 values, But I want to add MyTable.C3, MyTable.C4 values from the table <MyTable>
I need to update a table using a stored procedure that "UPSERTS". In this case, @OfficeId is passed with ParameterDirection.OutputSo when I update I assign the value to OfficeId like this (the office id value is being correctly assigned): SqlParameter OfficeIdParam = new SqlParameter("@OfficeId", SqlDbType.Int, 4); if (_officeId > 0) { OfficeIdParam.Value = _officeId; } OfficeIdParam.Direction = ParameterDirection.Output; The following segment of the stored procedure is throwing an error that the OfficeId does not exist: Update --- @OfficeId int output if not exists (select 1 from ORG_Office where OfficeId=@OfficeId) begin RAISERROR ('OfficeId does not exist in ORG_Office: E002', 16, 1) -- OfficeId does not exist. return -1 end May this approach work, and if the operation turns out to be an Insert I may do this:select @error_code = @@ERROR, @OfficeId= scope_identity() Thank you,jspurlin
I am trying to update a table and then also use OUTPUT clause to capture some of the columns. The code that I am using is something like the one below
UPDATE s SET Exception_Ind = 1 OUTPUT s.Master_Id, s.TCK_NR INTO #temp2 FROM Master_Summary s INNER JOIN Exception d ON d.Id = LEFT(s.Id, 8) AND d.Barcode_Num = s.TCK_NR WHERE s.Exception_Ind IS NULL
The above code is throwing an error as follows:
Msg 4104, Level 16, State 1, Procedure Process_Step3, Line 113 The multi-part identifier "s.Master_Id" could not be bound. Msg 4104, Level 16, State 1, Procedure Process_Step3, Line 113
The multi-part identifier "s.TCK_NR" could not be bound.
I have a small problem in parameter mapping for Execute SQL Task. I am using a delete statement with 2 conditions. Followed by another Execute SQL Task which contains commit statement.
delete from tname where c1 = ? and c2 =?
where c1 is number(4) datatype and c2 is of varchar2(20) datatype in oracle.
The connection manager i am using is ORacle OLE DB provider. I am passing 2 global variables i.e g_v1 of Int32 and g_v2 of String Type.
In the parameter mapping of the Executing SQL task, i am mapping these 2 variables for c1 and c2 and changed the datatypes inside parameter mapping as Numeric for c1 and Varchar for c2.
I also set the property as ByPassPrepare = True.
When i am executing the package i getting INVALID NUMBER ERROR. i believe the SSIS is unable to perform the implict datatype converison.
For the next run, i changed the g_v1 varible datatype to Double and also i changed the parameter mapping for c1 as Doble datatype. This time it is working fine. I can see the Green signal for the 2 SQL Tasks.
But when i connected to Oracle check the count in the table, the data is not getting deleted.
Also, I set the property RetainSameConnection = TRUE for oracle connection manager. I am not able to trace this logical error.
The same is working fine in my local machine. But i am facing the problem when i deployed the same on the client machine.
Is there any problem with parameter mapping? What should be equialent Datatype for Oracle NUMBER datatype that should be used inside the SSIS package while declaring the global variable and inside the parameter mapping.
I need to pass in null/blank value in the date field or declare the field as string and convert date back to string.
I tried the 2nd option but I am having trouble converting the two digits of the recordset (rs_get_msp_info(2), 1, 2))) into a four digit yr. But it will only the yr in two digits. The mfg_start_date is delcared as a string variable
option 1 I will have to declare the mfg_start_date as date but I need to send in a blank value for this variable in the stored procedure. It won't accept a null or blank value.
We have some URLs within a bulk block of text some of which are very long. I need to identify rows where such urls exceed say 100 characters in length in amongst other text.So the rule would be return a record if within the string there is a string (without spaces) longer than 100 characters.
Arvind writes "i want to create a stored procedure returns an OUTPUT variable containing the no. of records given by a query, the query being dynamic. Preferrably the query should also be passed as a parameter to the stored procedure...If not,it should be constructed in the SP and a Part of the where clause is dependant on the value of another variable passed to the SP.
How should the query be constructed, executed, and then the Count(*) value returned?
"WHERE <condition1> AND <condition 2> ;
"AND <condition 2> " may exist or may not exist in the query; it is dependant."
