SQL Server 2012 :: Dynamic Query On DB Table Names
Mar 9, 2015
I have query which is used to dynamically insert value but not working. We are trying to get all table names and insert dynamically to all tables by looping through table names.
declare @a varchar(max),@i int;
declare @table table(rno int, name varchar(max))
declare @b varchar(max)
insert into @table
select row_number() over( order by table_name) rno, table_name from INFORMATION_SCHEMA.tables
declare @tblname varchar(max)
[Code] .....

I don't know why this is so difficult. What I want to do is take a table name as a parameter to build a query and get an integer value from the result of the query. But from all of the research I have been doing, Dynamic SQL is bad in SQL server because of SQL Injections. But my users are not going to be supplying the table names.
Things I have learned:
- SQL Functions cannot use Exec to execute query strings.
- SQL Functions can return a concatenated string that could be used by a stored procedure to Exec the query string.
So how can I write a stored procedure that will
1. take a parameter
2. Pass the parameter to a function that will return a string
3. Execute that string as SQL
4. Get a return value from that SQL statement
5. Then finally, from a View, how can I pass a parameter to the stored procedure and get the returned value from the stored procedure to be used as a field in the View?
Numbers 3, 4, and 5 are where I am really stuck. I guess I don't know the proper syntax and limitations of SQL Server.

I have started working with dynamic queries recently. I am using a table variable and need to add a join in query dynamically.
For Eg- @TableVariable
SET @query_from = @query_from + CHAR(10) + ' JOIN @TableVariable on ABC.ID = @TableVariable.ID '
BUt it gives an error that @TableVariable must be declared

I have a function that returns a table from a comma-delimited string.
I want to take this a step further and create a function that will return a set of tablenames in a table based on a 'group' parameter which is a simple integer...1->9, etc.Obviously, what I am doing is not working out.
CREATE FUNCTION dbo.fnReturnTablesForGroup
(
@whichgroup int
)
RETURNS @RETTAB TABLE (
TABLENAME VARCHAR(50)
[code]....

I need to ensure some naming standards to users while creating tables.
All table name should be in same pattern
(ie., ) TeamName_EmpId_tablename
I need a way to restrict user to follow the naming standard. If any user tries to create table without the above naming standard system should not allow.

In a stored procedure I dynamically create a temp table by selecting the name of Applications from a regular table. Then I add a date column and add the last 12 months. See attachment.
So far so good. Now I want to update the data in columns by querying another regular table. Normally it would be something like:
UPDATE ##TempTable
SET [columName] = (SELECT SUM(columName)
FROM RegularTable
WHERE FORMAT(RegularTable.Date,'MM/yyyy') = FORMAT(##TempMonths.x,'MM/yyyy'))
However, since I don't know what the name of the columns are at any given time, I need to do this dynamically.
how can I get the column names of a Temp table dynamically while doing an Update?

Hi all,
I have been attempting to construct some dynamic SQL using a table name as a parameter, and call it using sp_executesql, in SQL Server 2005.
According to all of the searches and articles I have read today, the following should work:
DECLARE @rownumINT
DECLARE @tabNamNVARCHAR(100)
DECLARE @SQLStringNVARCHAR(500)
DECLARE @ParmDefinition NVARCHAR(500)
SET @rownum = 35
SET @tabNam = 'AdminScriptHistory'
SELECT @SQLString = N'SELECT * FROM @table where executionorder=@row'
SET @ParmDefinition = N'@table VARCHAR(100), @row INT'
EXEC sp_executesql @SQLString, @ParmDefinition, @tabNam,@rownum
However, it fails with:
Msg 1087, Level 15, State 2, Line 1
Must declare the table variable "@table".
Anybody know why?
Cheers

I am creating a dynamic query where i am appending a where clause something like -
IF (@CurCaptureDate IS NOT NULL)
SET @where_clause = @where_clause + CHAR(10) + 'AND CD.CaptureDate = ' + @CurCaptureDate
PS - CD.CaptureDate is datetime and @CurCaptureDate is also datetime
but when executing , it gives this error - Msg 241, Level 16, State 1, Line 169 Conversion failed when converting date and/or time from character string.
i am not able to use convert here with these quotes.
i tried this - SET @where_clause = @where_clause + CHAR(10) + 'AND CD.CaptureDate = ' + CONVERT(VARCHAR(25),@CurCaptureDate )
but it makes it to -
AND CD.CaptureDate = Jul 19 2014 12:00AM. I would need the date in quotes.

Hello all,
Im just wondering... is there any way to have dynamic table names, so that, say for instance, i have 4 stored procedures, that all do the same thing, just to four different tables. is there any way to have 1 stored procedure, and pass through the table name???
Adding the four statements into one statement is not an option, as i only need to execute one at a time..., not all four at once...
Cheers,
Justin

2. The project on which i am working correctly have a case where in i get the update of my status flag after few days (Say 15 - 30) in that case if my data got into partition table how to update and how to search which partition has my data
3. Is creating partition occupies more disk space?
4. Is every partition would need index?

I am trying to select data from table that have YYMM as table names, they are formatted table1410,table1411, table1412. I am trying to format it like this
declare @tablename60 varchar(50) = 'table' + SUBSTRING(CAST(DATEPART(YY,dateadd(yy, -1, getdate())) as varchar(4)),3,4) + SUBSTRING(CAST(DATEPART(MM,dateadd(mm, -1, getdate())) as varchar(2)),1,2)
But this is hard coding the YYMM, and I would like to have it pull 30,60,90 days fromthe first of the current month. I am having a bit of trouble formatting, how to accomplish this.

I am having trouble figuring out why the following code throws an error:
declare
@cols nvarchar(50),
@stmt nvarchar(max)
select @cols = ('[' + W.FKStoreID + ']') from (select distinct FKStoreID from VW_PC_T) as W
select @stmt = '
select *
[Code] ...
The issue that I am having is:
Msg 245, Level 16, State 1, Line 4
Conversion failed when converting the varchar value '[' to data type int.
I know that I have to use the [ ] in order to run the dynamic sql. I am not sure what is failing and why as the syntax seems to be clean to me (obviously it is not).

I am trying to pivot table DYNAMICALLY but couldn't get the desired result .
Here is the code to create a table
create table Report
(
deck char(3),
Jib_in float,
rev int,
rev_insight int,
jib_out float,
[Code] .....
Code written so far. this pivots the column deck and jib_in into rows but thats it only TWO ROWS i.e the one i put inside aggregate function under PIVOT function and one i put inside QUOTENAME()
DECLARE @columns NVARCHAR(MAX), @sql NVARCHAR(MAX);
SET @columns = N'';
SELECT @columns += N', p.' + QUOTENAME(deck)
FROM (SELECT p.deck FROM dbo.report AS p
GROUP BY p.deck) AS x;
[Code] ....
I need all the columns to be pivoted and show on the pivoted table. I am very new at dynamic pivot. I tried so many ways to add other columns but no avail!!

I have this query:
SELECT TOP (100) PERCENT dbo.Filteredfs_franchise.fs_franchiseid AS FranchiseId, dbo.Filteredfs_franchise.fs_brandidname AS Brand,
dbo.Filteredfs_franchise.fs_franchisetypename AS [Franchise Type], dbo.Filteredfs_franchise.fs_franchisenumber AS [Franchise Number],
dbo.Filteredfs_franchise.fs_transactiontypename AS [Transaction Type], dbo.Filteredfs_franchise.fs_franchisestatusname AS [Status Code],
[Code] ....
I need to pivot this so I can get one row per franchiseID and multiple columns for [Franchisee Name Entity] and [Franchise Name Individual]. Each [Franchisee Name Entity] and [Franchise Name Individual] has associated percentage of ownership.
This has to be dynamic, because each FranchiseID can have anywhere from 1 to 12 respective owners and those can be any combination of of Entity and Individual. Please, see the attached example for Franchise Number 129 (that one would have 6 additional columns because there are 3 Individual owners with 1 respective Percentage of ownership).
The question is how do I PIVOT and preserve the percentage of ownership?

Within a trigger, I'm trying to create a unique table name (using the NEWID()) which I can store the data that is found in the inserted and deleted tables.
Declare @NewID varchar(50) = Replace(convert(Varchar(50),NEWID()),'-','')
Declare @SQLStr varchar(8000)
Set @SQLStr= 'Select * into [TMPIns' + @newID + '] from inserted'
Exec (@SQLStr)
I get the following error: Invalid object name 'inserted'
I know I can do:
Select * into #inserted from inserted
Set @SQLStr= 'Select * into [TMPIns' + @newID + '] from #inserted'
Exec (@SQLStr)
But I don't want to use TempDB as these tables can become big and I also feel that it is redundant. Is there a way to avoid the creation of #inserted?

I am trying to query the SharePoint database to get a list of how many times a table name is being used in our SSRS reports.Here is my current query:
DECLARE @TEXTTOSEARCH AS VARCHAR(200)
SET @TEXTTOSEARCH = 'tablenamehere'
;WITH XMLNAMESPACES
(DEFAULT 'http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefinition',
'http://schemas.microsoft.com/SQLServer/reporting/reportdesigner' AS rd)
[code]...
This works for some tables since the names are unique and I can just do a search for that. However, some of the table names are simple and can also be used as aliases.if there was some way to get the list of table names easier.

I am building an SSIS package that is hitting about 50 remote servers. I have a for each loop container that i am using to build the list of servers to run.
The problem is...sometimes networks go down, sometimes connections time out and this causes my entire package to fail. I inserted a task that will run select @@ServerName on the remote server inside the loop. My thought was, if this returns an error I could ignore it and move on to the next server in the list and log somewhere that server x threw an error. Logging is easy, the problem is, how do I then tell it to move on to the next server in the loop?
If anyone has any suggestions on how better to do this, I am open for alternatives...

I have a table named 'DepartmentItem' which is designed with hierarchy structure. The column 'ParentId' from table DepartmentItem indicates parent-child relationship and department root among records. I have written and run a user-defined function I use recursive approach, but the function runs slowly.
My question: is there a better way to query that hierarchy table instead of using recursive?
** The current user-defined function that is written using recursive:
CREATE FUNCTION dbo.fnGetDepartmentTree
(
@departmentItemId int
)
RETURNS TABLE
AS
RETURN
with DepartmentItemTree(DepartmentItemId , DepartmentItemTypeId , ParentId, ItemOrder, Level)
[code].....
** And definition of table 'DepartmentItem' :
DepartmentItemId int IDENTITY(1,1) NOT NULL,
ParentId int NULL, -- Each department root starts when this column is NULL or the current row is department root. If it is not NULL then the current row has ParentId whose record has DepartmentItemId = ParentId of the current row (see more below)
IsActive bit NOT NULL DEFAULT ((1)),
