Does anyone know about that?
Hi guys, If I have a temporary table called #CTE With the columns [Account] [Name] [RowID Table Level] [RowID Data Level] and I need to change the column type for the columns: [RowID Table Level] [RowID Data Level] to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time. What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance, Aldo.
I have tried the code below, but getting syntax error...
ALTER TABLE #CTE ALTER COLUMN [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE MODIFY [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I have created a single FULLTEXT on col2 & col3. suppose i want to search col2='engine' and col3='toyota' i write query as
SELECT
TBL.col2,TBL.col3 FROM
TBL INNER JOIN
CONTAINSTABLE(TBL,col2,'engine') TBL1 ON
TBL.col1=TBL1.[key] INNER JOIN
CONTAINSTABLE(TBL,col3,'toyota') TBL2 ON
TBL.col1=TBL2.[key]
Every thing works well if database is small. But now i have 20 million records in my database. Taking an exmaple there are 5million record with col2='engine' and only 1 record with col3='toyota', it take substantial time to find 1 record.
I was thinking this i can address this issue if i merge both columns in a Single column, but i cannot figure out what format i save it in single column that i can use query to extract correct information. for e.g.; i was thinking to concatinate both fields like col4= ABengineBA + ABBToyotaBBA and in search i use SELECT
TBL.col4 FROM
TBL INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABBToyotaBBA"') TBL1 ON
TBL.col1=TBL1.[key] Result = 1 row
But it don't work in following scenario col4= ABengineBA + ABBCorola ToyotaBBA
SELECT
TBL.col4 FROM
TBL INNER JOIN
CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABB*ToyotaBBA"') TBL1 ON
TBL.col1=TBL1.[key]
Result=0 Row Any idea how i can write second query to get result?
I am trying to add columns to several tables in a singular database. I want to check to see if the column exists in a given table first before executing the alter table command so that I can skip that command if the column already exists, and avoid aborting my script prematurely. I can't seem to find a way to check for the column's existance. Any suggestions?
I've some huge table (over 100GB each), these table contain column of NTEXT, IMAGE. Application team needs to change these data types to VARBINARY(MAX), I've tested the modification in our lab and I noticed that the operation has been almost immediate so, I think that DB Engnine has not converted the existing data in the column but it has simply changed the definition of the column.
Or maybe NTEXT and IMAGE can be transparently converted into VARBINARY(MAX)?
Anyway, I want to be sure that the modified table is "coherent" I don't want that at a given point SQL Server tells me that some data is not readable.
I am renovating an existing application and am converting the existing passwords into hashed values using SHA1. I know how to compute the hashed values as a byte array for each record. What I don't know how to do easily is update all of the records i a single call to the database. Normally, I would just do the following:UPDATE HashedPassword = someValue WHERE UserID = 101; UPDATE HashedPassword = someOtherValue WHERE UserID = 102; ...
What I don't know is what someValue and someOtherValue should be. How do I convert my byte array into string representation that SQL will accept? I usually execute multiple statements using Dim oCmd as New SqlCommand(sSQL, MyConn) and then call oCmd.ExecuteNonQuery(). Alternatively, I found the following code that uses the byte array directly but only shows a single statement. How could I use it to execute multiple statements as shown above?'FROM http://aspnet.4guysfromrolla.com/articles/103002-1.2.aspx
'2. Create a command object for the query Dim strSQL as String = _ "INSERT INTO UserAccount(Username,Password) " & _ "VALUES(@Username, @Password)" Dim objCmd as New SqlCommand(strSQL, objConn)
'3. Create parameters Dim paramUsername as SqlParameter paramUsername = New SqlParameter("@Username", SqlDbType.VarChar, 25) paramUsername.Value = txtUsername.Text objCmd.Parameters.Add(paramUsername)
Dim paramPwd as SqlParameter paramPwd = New SqlParameter("@Password", SqlDbType.Binary, 16) paramPwd.Value = hashedBytes objCmd.Parameters.Add(paramPwd)
'Insert the records into the database objConn.Open() objCmd.ExecuteNonQuery() objConn.Close()
I have taken more than one database backups and i have an idea that we can verify single backup using "restore verifyonly from disk='<path>'" statement. Now my question is Could we verify all(More than one backup) backups with single statement? Any suggestion would be helpful to me:-)
how we can replace the multiple values in a single select statement? I have to build the output based on values stored in a table. Please see below the sample input and expected output.
I have created a trigger that is set off every time a new item has been added to TableA.The trigger then inserts 4 rows into TableB that contains two columns (item, task type).
Each row will have the same item, but with a different task type.ie.
I've 2 tables QuestionAnswers and ConditionalQuestions and fetching data from them using CTE join and I'm seeing repetitive rows (not duplicate) like, If you have multiple answers for 1 question, the output is like
where london where paris where toronto
why us why japan why indonesia
I want to eliminate the repetitive question and group them as parent child items.
with cte as ( select cq.ConditionalQuestionID from ConditionalQuestions cq inner join QuestionAnswers qa on cq.QuestionID=qa.QuestionID where cq.QuestionID=5 and qa.IsConditional='Y') select distinct q.Question, a.Answer from QuestionAnswers qa inner join Answers a on a.AnswerID = qa.AnswerID inner join Questions q on q.QuestionID = qa.QuestionID inner join cte c on c.ConditionalQuestionID = qa.QuestionID;
With the below query iam able to retrieve all the tables invloved in a stored proc. But, what I want to display the table names as comma separated list for each table.
;WITH stored_procedures AS ( SELECT o.id, o.name AS proc_name, oo.name AS table_name, ROW_NUMBER() OVER(partition by o.name,oo.name ORDER BY o.name,oo.name) AS row FROM sysdepends d INNER JOIN sysobjects o ON o.id=d.id INNER JOIN sysobjects oo ON oo.id=d.depid WHERE o.xtype = 'P') SELECT id,proc_name, table_name FROM stored_procedures WHERE row = 1 ORDER BY proc_name,table_name
I joined these two tables and it pulled up the proper amount of records. If you check out the image you will see what the results are for this query.
Now all I need for this part would be to roll these up where I have one row per ProgramID and all the AttributeNames' together in a AttributeNames column for each id.
EXAMPLE: All in one row.
ProgramID | AttributeNames 887 | Studydesign, Control Groups, Primary Outcomes.
I have attached an image of the SQL VIEW that I need to modified so it does this.
THE QUERY:
SELECT TOP (100) PERCENT dbo.tblProgramAttributes.ProgramID, dbo.tblProgramAttributes.AttributeID AS PAattributeID, dbo.tblAttributes.AttributeID, dbo.tblAttributes.AttributeName FROM dbo.tblProgramAttributes INNER JOIN dbo.tblAttributes ON dbo.tblProgramAttributes.AttributeID = dbo.tblAttributes.AttributeID WHERE (dbo.tblProgramAttributes.AttributeID NOT LIKE '%ProgramType%') ORDER BY dbo.tblProgramAttributes.ProgramID DESC
Scenario is like that single dept can have multiple LocationHeads, If Location heads are multiple then they should display in single column using *starting the name as mentioned bottom under required output.
Below is sample of data:
create table #Temp(depID int, Name varchar(50),LocationHead varchar(50)) insert into #temp values(1,'test','head1') insert into #temp values(1,'test','head2') insert into #temp values(1,'test','head3') insert into #temp values(2,'test1','head1') insert into #temp values(2,'test1','head2')
Required output
depID Name LocationHead 1test *head1,*head2,*head3 2test1 *head1,*head2
Suppose that I have a table with following values Table1 Col1 Col2 Col3 ----------------------------------------------------------- P3456 C935876 T675 P5555 C678909 T8888
And the outcome that I want is: CombinedValues(ColumnName) ---------------------------------------------- P3456 - C935876 - T675 P5555 - C678909 - T8888
where CombinedValues column contains values of coulmn 1,2 & 3 seperated by '-' So is there any way to achieve this?
I am trying to replace all special characters in a column with one special character.
Example:
Table: dbo.Employee Column: Name Name ------- edwardneuman!"<] mikemoreno)'>$: JeffJensen"?>"
I am trying to get the namepart to the left of ANY special character. To achieve this, I am thinking of replacing all the special characters with a single special character so that I can find the first occurrence of that special character and grab left of the special character (SUBSTRING/CHARINDEX). This way I don't need to loop through all the special characters.
I am expecting the following results:
Name ------- edwardneuman<<<< mikemoreno<<<<< JeffJensen<<<<
I have a description field in a table which also stores unit of measure in the same column but with some space between them, I need to split these into two different columns.
Hi people,I?m trying to alter a integer field to a decimal(12,4) field in MSACCESS 2K.Example:table : item_nota_fiscal_forn_setor_publicofield : qtd_mercadoria integer NOT NULLALTER TABLE item_nota_fiscal_forn_setor_publicoALTER COLUMN qtd_mercadoria decimal(12,4) NOT NULLBut, It doesn't work. A sintax error rises.I need to change that field in a Visual Basic aplication, dinamically.How can I do it? How can I create a decimal(12,4) field via script in MSACCESS?Thanks,Euler Almeida--Message posted via http://www.sqlmonster.com
Deciding whether or not to use a CTE or this simple faster approach utilizing system tables, hijacking them.
SELECT s.ORDER_NUMBER, s.PRODUCT_ID, 1 AS QTY, s.VALUE/s.QTY AS VALUE FROM @SPLITROW s INNER JOIN master.dbo.spt_values t ON t.type='P' AND t.number BETWEEN 1 AND s.QTY
Just wanted to know if its okay to use system tables in a production environment and if there are any pit falls of using them ?
How do I pass a single column of values from a successful merge join to an EXECUTE SQL statement so it can be used with an "IN" criteria of the WHERE clause? Here's an example of my update statement with two random key values:
UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK IN ("XYZ123", "DEF890")
Is this even possible in SSIS, or am I better off using a loop and running the update EXECUTE SQL Statement for each individual key value, as in the following example?
UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "XYZ123" UPDATE dbo.MyTable SET MyStatus = 1 WHERE MyPK = "DEF890"
I'm working on a script to merge multiple columns(30) into a single column separated by a semicolons, but I'm getting the following error below. I tried to convert to the correct value. but I'm still getting an error.
Error: "Conversion failed when converting the varchar value ';' to data type tinyint".
I'm new to SQL Server but not new to SQL because I used it with Oracle. I wonder if it is possible to do this kind of statement on SQL Server:
UPDATE TableX M SET (M.column1, M.column2, M.column3)= (SELECT T.column1, T.column2, G.column3) FROM Table_Y T, Table_Z G WHERE join condition)) WHERE EXISTS (join condition for TableX)
Basically, I'd like to update multiple columns in one statement but for some reason I can not get it to work.
