Hi,
I need do get a columns names from a table? How to do this in pure SQL?
I thought about creating a stored procedure or user function with a result of a string ( col1name,col2name ....)
I do not know how to count the number of columns in a specyfied table?
Any help would be appreciated.
Thanks in advance.

I am able to get a list of columns in a table from the query I have written shown below:
select sc.name ColumnNames,st.name TableName from sys.columns sc inner join sys.tables st on sc.object_id=st.object_id
order by st.name
But I am looking for the resultset with the format below:
TableName  Columns
employee    employeeid,employeename,employeesalary
order       orderid,address,priceÂ
Hello,
I've been able to startup a transactional replication between 2 database for some tables that only have different table names. Now there are still some tables that not only have different names but also different column names, can this be done in the wizzard ??
Thx
I am using CROSS APPLY instead of UNPIVOT to unpivot > one column. I am wondering if I can dynamically replace column names based on different tables? The example code that I have working is based on the "Allergy" table. I have thirty more specialty tables to go. I'll show the working code first, then an example of another table's columns to show differences:
select [uplift specialty], [member po],[practice unit name], [final nomination status]
,[final uplift status], [final rank], [final uplift percentage]
,practiceID=row_number() over (partition by [practice unit name] order by Metricname)
,metricname,Metricvalue, metricpercentilerank
[code]....
Rheumatology Table:The columns that vary start with "GDR" and [GDR Percentile Rank] so I'm just showing those:
GDR (nvarchar(255), null)
GDR Percentile Rank (nvarchar(255), null)
GDR PGS (nvarchar(255), null)
GDR Rank Number (nvarchar(255), null)
PMPM (nvarchar(255), null)
[Code] ....
These are imported from an Excel Workbook so that's why all the columns with spaces for now.
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.
Hi
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.
Thanks.
I need a querry to get all columns names.

I'm trying to do an update query that looks like this:
UPDATE
PAEMPLOYEE
SET PAEMPLOYEE.LOCAT_CODE = EMPLOYEE.PROCESS_LEVEL
FROM
PAEMPLOYEE A
JOIN EMPLOYEE B ON A.EMPLOYEE = B.EMPLOYEE
It's erroring out on the Employee prefix B.EMPLOYEE saying:
..."does not match with a table name or alias name used in the query"
Is it wrong or will it cause problems to have a field name the same as the table name?
Hey,
I'm creating registration form.
To show fields names I thought to read columns names.
It's ok if columns is named like "Name", "Age" etc.
But if the columns is named [Country, Address, PostCode] then, I think, it can course some problems. Am I right?
First problem I thought about - changing database in the future (Now MS SQL 2k to MySQL etc.)
Is this the only problem?
To solve this I think using table which store syscolumn names as user defined columns names.
My system is speed critical and using this I would get less performance.
Which way should I go?
Case saving columns names in table, how to generate safe column name from user specified name, which can have special charters.
Thanks
Hi,
I am looking for some help in MS SQL server. I want to access the columns of a table without using the names of the colulmns.
Example - SELECT table1.field[1], table1.field[2] FROM table1;
Any information to this effect is much appreciated.

I have one column name that is: description
when i write a query the world lights up with blue, I think I saw someone using [ ] around the word but I no longer remember if this is the way to handle reserve words that have been use as columns names
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
I'm looking for a query that will return all index names, the table the index is on and the columns in the index...
View 1 Replies View RelatedI've got a database with an unknown number of columns. Hence, the column names are also unknown. What's the easiest SQL to present the values in each column and the column headings?
View 1 Replies View Relatedhi,
i am sure this question must have been anwsered some where, but after a lot of searching i still have not find the anwser.
i have flat files without column headers (267 columns in total).
since i have the file's description i have created a table to house these extracts with the columns in the same order as in the flat files.
additionally, i have an excel containing a list of the column names their data types and length as well as their position on the flat files.
in the old, DTS would map the columns without headers to those columns in the destination table using their order, in which case it works like a breeze for me. but i can not find a way of doing that in SSIS.
i would very much appreciate someone's assistance on this one since i am sure that there must be a better way than manually (and tediously & error prone) to map all those columns.
thanks in advance
I am trying to do a PIVOT on a query result, but the column names created by the PIVOT function are dynamic.
For example (modified from the SQL Server 2005 Books Online documentation on the PIVOT operator) :
SELECT
Division,
[2] AS CurrentPeriod,
[1] AS PreviousPeriod
FROM
(
SELECT
Period,
Division,
Sales_Amount
FROM
Sales.SalesOrderHeader
WHERE
(
Period = @period
OR Period = @period - 1
)
) p
PIVOT
(
SUM (Sales_Amount)
FOR Period IN ( [2], [1] )
) AS pvt
Let's assume that any value 2 is selected for the @period parameter, and returns the sales by division for periods 2 and 1 (2 minus 1).
Division CurrentPeriod PreviousPeriodA 400 3000 B 400 100 C 470 300 D 800 2500 E 1000 1900
What if the value @period were to be changed, to say period 4 and it should returns the sales for periods 4 and 3 for example, is there a way I can change to code above to still perform the PIVOT while dynamically accepting the period values 4 and 3, applying it to the columns names in the first SELECT statement and the FOR ... IN clause in the PIVOT statement ?
Need a way to represent the following [2] and [1] column names dynamically depending on the value in the @period parameter.
[2] AS CurrentPeriod,
[1] AS PreviousPeriod
FOR Period IN ( [2], [1] )
I have tried to use the @period but it doesn't work.
Thanks in advance.

I am imagining something you might pass the names of 2 stored procs (an old version and new one), and a query to produce valid parameters. It would then fire off each proc for a set number of executions, while storing off the results in temp tables, and at the end it would do a data compare, and store off performance data from dynamic management views.
Now I know how to get the parameters for a stored procedure out of the catalogue views, but is SQL Server aware at all of the schema of the results of stored procedures that return result sets, becuase I was thinking of doing something like...
INSERT INTO #datacompare(col1,col2)
EXEC mystoredprocedure
... but I can not seem to figure out how to dynamically gather the schema of the result set.
I am trying to figure out how to pivot a temporary table. I have a table which starts with a date but the number of columns and columns names will vary but will be type INT (Data, col2,col3,col4………….n)
So it could look like
Date , TS-Sales, Budget , Toms sales
01-Jan-14,100,120,300
02-Jan-14,80,150,300
03-Jan-14,100,20,180
Turned to this
01-jan-14, 02-jan-14, 03-jan-14
100,80,100
120,150,20
300,300,180
Or even just the date and a SUM
What I want is to be able to sum al the columns but without knowing the name and the amount columns to start with this is a manually processes. How could I automate this?
While looking forward to design a multi-columnar cross-tab query I am anxious to know if there could be a way to change the default names of the pivot columns? In other words for the query like the following can there be a way to apply anAS type command to reflect some other names, instead of having the four dates in heading? Something like Month_A, Month_B?
SELECT * FROM
(SELECT
X.REP_DT,
X.CUST_ID
AMOUNT_1
FROM
X) P
PIVOT (SUM(AMOUNT_1) FOR REP_DT IN ([2014-12-31], [2015-01-31], [2015-02-28], [2015-03-31])) PVT_01
So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3
**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select
Test_Name AS 'Test_Name',
Table_Bird.Animal AS 'Birds',
Table_Mammal.Animal AS 'Mammal',
Table_Reptile.Animal AS 'Reptile,
Table_Fish.Animal AS 'Fish'
From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.
I need to find column names if any after 2 “check” columns.
Scenario: I have a database, with approx 400-1500 tables, depending on installation of software. The software is structured so that, when it synchronizes the SQL database it will create all the columns e.g. custacc, custname etc. and then it will always put in two check columns “CheckOne” and “CheckTwo” these two columns has to be the two last ones. In 99.9 this always works fine, but sometime if the users creates a new field in the software, when it synchronizes the new field “lands” behind the two checkfields, which is not good.
So what I am after is a script, which can run through all user tables, tell me if there are columns after the two checkfields and list those tables if any.
Any help would be greatly appreciated.
Cheers
Henrik.
I€™m using the ImportExport wizard to export the top 5 lines from a MS Sql table into a fixed format (€śragged€?) file. But I want the first record to contain the column names of the exported fields so I selected the €śColumn names in the first data row€? option of the €śChoose a Destination€? box. When I run the Package I get:

When I de-select the €śColumn names€? option, the package works fine. Other than manually, how can I et the column names in output file?

 I have a situation where I want to load the Excel file dynamically, and the excel file have different columns or even worksheet name. How I could approach this? I believe there's no way to modify the meta data (specifically the mapping) in the data flow.

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.
how to solve that problem?
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?
Thanks for the help.
I have a function that returns a table from a comma-delimited string.

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)?
Hi,
I have two tables
Table Source
{
category varchar(20),
LastUpdate datetime
}
Table Destination
{
SubjectId varchar(20),
SubjectDate datetime,
category varchar(20),
LastUpdate datetime
}
Please note that the number columns are different in each table.
I wanted to dump the data of Source table to Destination table. I meant to say that the rows of 2 columns in Source table to last 2 rows of Destination table.
And also my oreder of the columns in Destination table will vary. So i need to a way to dynamically insert the data in bulk. but i will know the column names for sure before inserting.
Is there anyway to bulk insert into these columns.
Your quick response will be appreciated

I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:
I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.
1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B
If updated my query (see below)Â and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.
2. My second question: How to i get around this error?
SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B, Â fnSplitJson2(A.ITEM6,NULL) C
I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.
Here is My requirement, I'm not sure if this is possible. Creating table called master like col1, col2 col3, col4 , col5 ...Where Col1, col2 are updatable - this can be done easily
Col3, col4 are columns in another table but these can be just a read only ?? Is this possible ? this is possible with View but not friendly with share point CRUD...Col 5 is a computed column of col 2 and col5 ? if above step can be done then sure this can be done I guess.
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.
Thx
