Hi, I am new to using SQL for anything more in depth than querying and reporting.
I am trying to create a series of SQL scripts which will be used across several customer sites so need to be easily customisable. What I want to do is have all of the table names, field names and customisable items handled by variables which will be declared and set at the beginning of the script, making them easy to find and change. The problem I am having at the moment is with creating a new table using variables for table name and field names, can anyone help?
set @a_fieldid1 = 'newFieldid'
set @a_tmptbl = 'newTable'
create table @a_tmptbl ( @a_fieldid1 varchar(15), value float, counter INT);
insert into @a_tmptbl values ( "foobar", 21.76, 1);
select * from @a_tmptbl;
The error I am getting is:
quote:Server: Msg 170, Level 15, State 1, Line 8
Line 8: Incorrect syntax near '@a_tmptbl'.
Server: Msg 137, Level 15, State 1, Line 10
Must declare the variable '@a_tmptbl'.
Server: Msg 137, Level 15, State 1, Line 12
Must declare the variable '@a_tmptbl'.
I have a cursor which populates a variable with the name of each user table within my DB. I'm trying to copy the tables one at a time by using a command like this: SELECT * INTO @NewTable FROM @OrigTable Query analyzer tells me that there's incorrect syntax near the keyword 'INTO'. This seems fair enough to me as I assume it's trying to put the data into the variable rather than the table name which is held within the variable. Does any know how I can get around this? Are there any alternative ways of copying the table structure (preferable without the data)?
How do I use table names stored in variables in stored procedures?
Code Snippetif (select count(*) from @tablename) = 0 or (select count(*) from @tablename) = 1000000
I receive the error 'must declare table variable '@tablename''
I've looked into table variables and they are not what I would require to accomplish what is needed. After browsing through the forums I believe I need to use dynamic sql particuarly involving sp_executesql. However, I am pretty new at sql and do not really understand how to use this and receive an output parameter from it(msdn kind of confuses me too). I am tryin got receive an integer count of the records from a certain table which can change to anything depending on what the user requires.
Code Snippet
if exists(Select * from sysobjects where name = @temptablename) drop table @temptablename
It does not like the 'drop table @temptablename' part here. This probably wouldn't be an issue if I could get temporary tables to work, however when I use temporary tables i get invalid object '#temptable'.
Heres what the stored procedure does. I duplicate a table that is going to be modified by using 'select into temptable' I add the records required using 'Insert into temptable(Columns) Select(Columns)f rom TableA' then I truncate the original table that is being modified and insert the temporary table into the original.
Heres the actual SQL query that produces the temporary table error.
Code Snippet Select * into #temptableabcd from TableA
Insert into #temptableabcd(ColumnA, ColumnB,Field_01, Field_02) SELECT ColumnA, ColumnB, Sum(ABC_01) as 'Field_01', Sum(ABC_02) as 'Field_02', FROM TableB where ColumnB = 003860 Group By ColumnA, ColumnB
TRUNCATE TABLE TableA
Insert into TableA(ColumnA, ColumnB,Field_01, Field_02) Select ColumnA, ColumnB, Sum(Field_01) as 'Field_01', Sum('Field_02) as 'Field_02', From #temptableabcd Group by ColumnA, ColumnB
The above coding produces
Msg 208, Level 16, State 0, Line 1
Invalid object name '#temptableabcd'.
Why does this seem to work when I use an actual table? With an actual table the SQL runs smoothly, however that creates the table names as a variable problem from above. Is there certain limitation with temporary tables in stored procedures? How would I get the temporary table to work in this case if possible?
i'm trying to create a stored procedure that takes 2 input parameters (taken from a querystring): a table name, and a number that needs to be checked whether it exists within that table. yes, i have different tables, one for each forum, so they will have the same structures -- i'm figuring this approach will result in faster page-load times if the tables have less in them. if everyone here tells me that having one table for all the forums will work fine, i'll just go that route, but if not, here's my procedure:
Create Procedure VerifySubjectNum (@forum_ID VARCHAR(10), @subject_num INT) As If Exists (SELECT subject_num FROM @forum_ID WHERE subject_num = @subject_num) Return 1 Else Return 0
when i try to create this, i get an error saying @forum_ID must be declared... why doesn't it work within the select for the EXISTS?
I would like to use variables to set the table name and some column names of a SQL Query in a stored procedure (the variable values will come from a webpage)... something like this:ALTER PROCEDURE dbo.usp_SelectWorkHours @DayName varchar,@DayIDName varchar AS BEGINSELECT @DayName.InTime1, @DayName.OutTime1, @DayName.InTime2, @DayName.OutTime2 FROM @DayName INNER JOINWorkHours ON @DayName.@DayIDName = @DayName.@DayIDName INNER JOINEmployees ON WorkHours.WorkHoursID = Employees.WorkHoursID END RETURN ...is this possible?? if so how? Thanks
I am a SSIS novice, and need help to do the following:
Every day a Table is generated by the system of format XR+present Year + present month + present day. My task is pretty simple. I am to devise a SSIS package that will import this table on to a different server.
I have defined the variable as user defined variable. I am also able to specify the variable in OLE db source editor -> Data Access Mode : Table name or view name variable. When I am click the 'Columns' feature, I get the following error
TITLE: Microsoft Visual Studio ------------------------------ Error at Data Flow Task [OLE DB Source [1]]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E37. Error at Data Flow Task [OLE DB Source [1]]: Opening a rowset for "xr+ convert(char(8),getdate(), 112)" failed. Check that the object exists in the database. ------------------------------ ADDITIONAL INFORMATION: Exception from HRESULT: 0xC02020E8 (Microsoft.SqlServer.DTSPipelineWrap) ------------------------------ BUTTONS: OK ------------------------------
In short can any one tell me a correct way of using a table name as variable in Data Access Mode : Table name or view name variable ?
One other question: can I make use of a dynamic SQL in Execute SQL Task? If yes, how do I write the query
I am writing an sproc for creating a table, but I don't know how I can use parameter values as object names (for example the name of the table needs to be [@sFile1+'_'+@sLinkName+'_'+@sFile2']. It seems that I could concatenate my whole CREATE TABLE string into a single variable and use EXEC to run it, but I'd prefer to be able to do it in the context of the sProc (I read that EXEC always has the current user's permissions). What is a good technique?
CREATE TABLE [@sFile1+'_'+@sLinkName+'_'+@sFile2] ( [GID_ID]uniqueidentifierROWGUIDCOLNOT NULL, ['GID_'+@sFile1]uniqueidentifierNOT NULL, ['GID_'+@sFile2]uniqueidentifierNOT NULL, CONSTRAINT ['LNK_'+@sFile1+'_'+@sLinkname+'_'+@sFile2] FOREIGN KEY(['GID_'+@sFile2]) REFERENCES [@sFile2](GID_ID) ON UPDATE NO ACTION ON DELETE NO ACTION NOT FOR REPLICATION, CONSTRAINT ['LNK_'+@sFile2+'_'+@sLinkname+'_'+@sFile1] FOREIGN KEY(['GID_'+@sFile1]) REFERENCES [@sFile1](GID_ID) ON UPDATE NO ACTION ON DELETE NO ACTION NOT FOR REPLICATION )
I've tried declaring and setting variables in my sql statement and then trying to use them instead of defining a column directly - sorry quite hard to explain, i'll do a simple example
eg
DECLARE @column DECLARE @value SET @column = 'col1' SET @value = 'bloggs'
Select * FROM table1 WHERE @column = @value
It keeps returning no results even though i've tried
Select * FROM table1 WHERE col1 = 'bloggs' -- which returns results
I realise its the column which is not being selected, but there must be a way by using a variable?
Hello, I'm quite new to T-SQL, but since I'm trying to create a statistics page on database contents (Counting savesets in Enterprise Vault saveset Databases) I prefer to do the coding in the databases. I create temp tables for the distinct partitions in the saveset table. Then I pass 2 variables to the EXEC function, but it seems unable to pass the ['+@idpartition+']-variable as a value: Declare @EVBase varchar(20)Declare @IdPartition INTSet @EVBase=(SELECT EVMbxName from Servers) Set @IdPartition=(SELECT TOP 1 Dist_Partitions FROM TEMP_EV1)EXEC('SELECT COUNT (IdPartition)FROM ['+@evbase+']..SAVESET SS LEFT OUTER JOIN SavesetStore SSS ON SS.SavesetIdentity = SSS.SavesetIdentityWHERE [IdPartition] = ['+@idpartition+'] AND StoreIdentifier IS NULL') Server: Msg 207, Level 16, State 3, Line 2Invalid column name '0'. If I change the last line to: WHERE [IdPartition] = 2 AND StoreIdentifier IS NULL')The script runs fine - but I need the value from the table. Any help will be appreciated. Best regards, Tim
I need to get the names of tables and fields (or atleast the fields) from a database. Is there a query I can use that will return what all the db's tables and those tables fields are?
I am designing a package to export staging tables into a flat file.The names of the tables will be: TableAStaging_YYYYMM and TableBStaging_YYYYMM. As you can see the names of the tables will be changing each month.
The flat files will have similar naming: C:MyPathFlatFileTableAStaging__YYYYMM and C:MyPathFlatFileTableAStaging__YYYYMM.I want to run the package as an sql job in two steps, one for each table.I need to dynamically pass the table names and file names (together with the path) to the IS package.
My query returns fields that have spaces in the names, for example:
select o.OrderID as 'INVOICE NUMBER', etc..
When I created the DataSet for this query in report designer, it changed all spaces in the field names to underscores, i.e. INVOICE_NUMBER.
This report must be exported to CSV, and the names of the fields (first row in csv) must have the spaces, not underscores. But it appears RS uses the field names (not the names in the column headers of the report table control) as the field names. Is there any way for me to force the field names in the first row of the csv to something other than the field names in the DataSet?
I was wondering if anyone has an idea of how we could find the table names and column names of the tables in our Sql server database at runtime/dynamically given our connection string? Please let me know.
I've called a resultset from SQL Server using an SQL Selection. I need to iterate over that entire result set (200+ columns/fields) and all I need are the random numbers contained in any of the rows/columns. I don't want to have to name each field/column and then use an if > 0 statement.Isn't there some way to generically loop through the column's by index or something instead of their field name so I can just use an integer loop to walk the dataset? I know there is I've done it about 5 years ago. The question is how do you do it in C#?SqlConnection thisConn = new SqlConnection(ConfigurationManager.ConnectionStrings["SQLQuery"].ConnectionString); SqlCommand thisCmd = new SqlCommand("Command String", thisConn); thisCmd.CommandText = "Select * from SelectionsByCountry where [" + DropDownList1.SelectedItem.ToString() + "] > '0'"; thisConn.Open(); SqlDataReader thisReader = null; thisReader = thisCmd.ExecuteReader(CommandBehavior.CloseConnection); while (thisReader.Read()) { DropDownList2.Items.Add(thisReader["System"].ToString().Trim());/*** There are 200+ columns left I want to walk over using a loop structure of some sort. How do I do that?*/ }- Rex

How can I create a Table whose one field will be 'tableid INT IDENTITY(1,1)' and other fields will be the fields from the table "ashu". can this be possible in SQL Server without explicitly writing the"ashu" table's fields name.
I am trying to get the contents of the Excel Files dynamically and dumping into the SQL Database using SSIS. Through WMI Event Watcher, I could find when one or more Excel files dumped in a particular folder and using ForEach Loop Container I was able to take all the filenames and pass it through Variables. But at the same time in the Data Flow, I have to pass each Sheet of an Excel File to the Excel Source control and export the data to my SQL Database using OLEDB Destination.
For that I need to get the names of each sheets in an Excel File and pass it to the Excel Source Control through variables. But when I give Data Access Mode as "Table name or view name variable" and provide the variable name in that, then it is giving an error message as "A destination table name has not been provided".
And at the same time, Since I was not able to provide an static Filename (as I am passing through Variables), when I tried to map the columns in the OleDB Destination, it is not allowing me to map the columns.
So all these things I should do at Run-time using Variables in SSIS. I don't want to hard-code any filenames or Sheet names. If any one of you have a solution, please share with me.
I want to have this query insert a bunch of XML but i get this error...

What am i doing wrong...Can anyone help me out!! Thanks!!
p.s I know this query looks crazy...

I have a list of items in one table and a field (pageName) in another table that may contain one of the aforementioned items somewhere within that field. There is no fixed position within the field where the itemNo may be so I can't just use SUBSTRING(pageName,2,5) in(select itemNo from tblItem).
Logically, it's like I need to combine IN and LIKE: select pageName where pageName LIKE IN %select itemNo from tblitemNo%..LIKE can only handle one comparison string.
Hello, Maybe anyone have done that before? I have table where i store SOURCE_TABLE_NAME and DESTINATION_TABLE_NAME, there is about 120+ tables. i need make SSIS package which selects SOURCE_TABLE_NAME from source ole db, and loads it to DESTINATION_TABLE_NAME in destination ole db.
I made such SSIS package. set ole db source data access mode to table or view name variable. set ole db destination data access mode to table or view name variable. set to variables defoult values (names of existing tables) but when i loop table names is changed, it reports error, that can map columns, becouse in new tables is different columns.
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)
Hello, It is possible to write stored procedures which take table names as parameters; is it also possible to do this with table valued functions?
For example, a simple stored procedure is this:
CREATE PROCEDURE SelectTop(@tableName sysname) AS BEGIN
Execute('Select top 10 * from ' + @tableName + ';')
END
I want to be able to do the analogous thing with a table valued function (so that I can query the result set, without having to create a temp table). How should I do this (i.e., pass a tablename as an argument to a table valued function)?
I am trying to update one table when records are inserted in another table.
I have added the following trigger to the table “ProdTr” and every time a record is added I want to update the field “Qty3” in the table “ActInf” with a value from the inserted record.
My problem appears to be that I am unable to fill the variables with values, and I cannot understand why it isn’t working, my code is:
ALTER trigger [dbo].[antall_liter] on [dbo].[ProdTr] for insert as begin declare @liter as decimal(28,6)
Hi there. I haven't been able to figure out how to join a table on column on multiple table names. Here's the situation:
I have a table "tblJob" with a key of jobID. Now for every jobID, the program creates a new table that keeps track of the stock before the jobId was processed and after it was processed to give accurate stock levels and show the difference in stock levels. So, a jobID of 355 would be related to the table: "tblPreStock_335" and "tblPostStock_335". These 2 tables have all the materials in stock and the quantity. Therefore they show how much material was used. I need to figure out the difference in the material in the stock before and after the processing.
That means that I have to get a stockID, get the associated pre and post tables, and then display the difference of ALL the materials in the pre and post tables.
Could someone help me get started on the right path? Even a link to similiar problem that I haven't found would be nice.
I like to print the table names that starts with 'table'. I'm getting the same table name four times. Instead of four different table name.

Hi all, By using below query i can get no of tables having the give column name in a particular database, SELECT COUNT(*) AS CounterFROM syscolumnsWHERE (name = 'empno') but i want to know the table names too? any one please suggest me how to find table names too...... In other words i know the particular column name and right now i want to know the table names in which this column name exists.
hi... can someone pls tell me the sql statement to 1)Select all the tables in SQL server(only the ones created by me) 2)Select all the column names from a given table
