In a stored procedure I'm creating...
IF OBJECT_ID('tempdb..##SUBOSummary') IS NOT NULL
/*Then it exists*/
DROP TABLE ##SUBOSummary
CREATE TABLE ##SUBOSummary
(
--RowID int not null identity(1,1) primary key,
RowNum int IDENTITY(1,1) NOT NULL,
Dept nvarchar(25) NOT NULL,
Last24 int,
WTD int,
MoTD int,
YTD int
)
I then want to add a series of data from another view, and I'll then fill the rest of the data rows in seperately:
INSERT INTO ##SUBOSummary SELECT DISTINCT vw_EmployeeDepartment.Dept FROM vw_EmployeeDepartment
I'm getting the following error:
Column name or number of supplied values does not match table definition.
I'm hazarding a guess that this is because I'm only populating a single field by the insert statement.
Is there a better way to acheive this?
The error, in truth, is quite clear here:
Column name or number of supplied values does not match table definition.
In your INSERT statement you're implying you want to insert values into all the columns (as you're not specifying which one), yet you're only supplying one column in your SELECT, so where does that value go? SQL Server has no idea.
You need to supply your column(s) in your INSERT clause:
INSERT INTO ##SUBOSummary (Dept)
SELECT DISTINCT vw_EmployeeDepartment.Dept
FROM vw_EmployeeDepartment;
On a different note, however, don't use a Global Temporary Table, they often perform very poorly.

I am creating a database interface to make some basic operations on tables.
CREATE TABLE products (
ID int IDENTITY(1,1) PRIMARY KEY,
Name VARCHAR(20)
)
As long as I have been using MySQL database, it worked correctly to insert DEFAULT value onto 'ID' column
INSERT INTO products (ID, Name) VALUES (DEFAULT, "ProductName")
But MS SQL won't let me do that, the error I get is DEFAULT or NULL are not allowed as explicit identity values..
I have been looking for solutions and couldn't find one - is there a way to include ID in the list of columns in the insert statement, but actually let the database handle the value to be inserted(auto-increment value)?
The answer to just not include ID in the list of columns is not solving my problem, as I access the database from a C++ program and try to do it as abstract as possible (and some different tables don't have auto-increment on ID)
Two solution :
ignore the ID column in the column list :
INSERT INTO products (Name) VALUES ('ProductName');
do not specify the column list if you want to insert in all columns except identity :
INSERT INTO products VALUES (DEFAULT, ProductName);
By the way, double quote must never be used for strings but only simple quote. Double quote is reserved for "abnormal" objest names...
You must be define the Id column like this:
[id] [int] IDENTITY(1,1) NOT NULL
This is my first question on this platform. I am working on a database project. I want to use autoincrement for my primary key for id, but also want to add an alphabet before it. Are there other ways to do it apart from using 2 columns declaring one as identity and casting the other? I have worked with stored procedures and triggers.
Thank you
PS: I want to do it using one column if possible
You won't be able to do this with just one column.
The best solution is to use
an ID INT IDENTITY(1,1) column to get SQL Server to handle the automatic increment of your numeric value
a computed, persisted column to convert that numeric value to the value you need
So try this:
CREATE TABLE dbo.tblCompany
(
ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
CompanyID AS 'CMP-' + RIGHT('00000' + CAST(ID AS VARCHAR(5)), 5) PERSISTED,
.... your other columns here....
)
Now, every time you insert a row into tblCompany without specifying values for ID or CompanyID:
INSERT INTO dbo.tblCompany(Col1, Col2, ..., ColN)
VALUES (Val1, Val2, ....., ValN)
then SQL Server will increase your ID value, and CompanyID will contain values like CMP-00001, CMP-00002,...... and so on - automatically. The CompanyID column will be fill automatically, by SQL Server, upon inserting a new row - so there's no need for triggers or stored procedures or anything else - just this declaration in your table definition.
UPDATE: if you're using SQL Server 2012 or newer, you can do it with just one column - if you also create a SEQUENCE - like this:
CREATE SEQUENCE SEQ_CompanyID
AS INT
START WITH 1000
INCREMENT BY 1;
CREATE TABLE dbo.Company
(
CompanyID VARCHAR(20) NOT NULL
CONSTRAINT DF_CompanyID
DEFAULT('CMP-' + CAST(NEXT VALUE FOR dbo.SEQ_CompanyID AS VARCHAR(10))),
CompanyName VARCHAR(100) NOT NULL,
----- other columns here
)
Now if you make sure to insert with omitting the CompanyID column in the insert statement, like this:
INSERT INTO dbo.Company (CompanyName)
VALUES ('Company #1'), ('Company ABC'), ('Company Three');
then you get CMP-1001', 'CMP-1002 etc. as your CompanyID, again, automatically handled by SQL Server upon inserting a new row.
I'm grabbing some rows from a table, manipulating them in a temp table, and then looking to insert them as new rows into my original table.
However, I'm running into an issue with the identity column, even when I don't have the identity column on my temp table. The identity column is an auto-incrementing int.
This seems like a simple thing I'm way overthinking.
select top 0 *
into #TestTable
from OriginalTable;
...
--insert and manipulate records
...
ALTER TABLE #TestTable
DROP COLUMN MyIdentityColumn;
DECLARE #InsertedRows TABLE (NewSeqNum INT);
INSERT INTO OriginalTable
OUTPUT MyIdentityColumn INTO #InsertedRows(NewSeqNum)
SELECT * FROM #TestTable
but I get this error:
An explicit value for the identity column in table 'OriginalTable' can only be specified when a column list is used and IDENTITY_INSERT is ON.
I absolutely do not want to set an explicit value, I want it to insert and give me the new identity (via #InsertedRows)
If you don't want to keep the id of inserted records, then you need to specify all your columns but the id column in the select. As general good practice, dont select *, always specify the columns you want to retrieve-insert.
INSERT INTO OriginalTable (col1, col2, col3...)
OUTPUT MyIdentityColumn INTO #InsertedRows(NewSeqNum)
SELECT (col1, col2, col3...) FROM #TestTable
If I'm understanding you, I think your problem is that you're trying to insert '*' into the original table - which means all of your columns from the temp table. Including your ID column (which you don't want to insert, because you're wanting it to auto-generate.)
Instead, I'd suggest doing something like this:
Select [ColumnB],[ColumnC],[ColumnD],[Etc] into your temp table
Select [ColumnB],[ColumnC],[ColumnD],[Etc] into your original table.
... aka, spell out the columns explicitly, and omit the Identity column.
I have a identity column and i have other column while inserting a new row in
table i need to insert into third column with concatenate of two columns result
For reference please see below table
------------------------------------------------
A | B | c
----------------------------------------------
1 | 33 | 133(1 [identity result] + 33)
2 | 112 | 2112
Please help me to solve this issue.
There is already an answer to this question but i think is not the best way to achieve it.
Here's an example on how to achieve it with a computed column.
CREATE TABLE dbo.calculatedTEST (
A INT IDENTITY(1,1) NOT NULL,
B INT NOT NULL,
c AS CONVERT(INT,CONVERT(VARCHAR(max),A)+CONVERT(VARCHAR(max),B))
)
insert into dbo.calculatedTEST
(B)
values
(1),
(1),
(2),
(2)
select * from dbo.calculatedTEST
A computed column is computed from an expression that can use other
columns in the same table. The expression can be a noncomputed column
name, constant, function, and any combination of these connected by
one or more operators. The expression cannot be a subquery.
Unless otherwise specified, computed columns are virtual columns that
are not physically stored in the table. Their values are recalculated
every time they are referenced in a query. The Database Engine uses
the PERSISTED keyword in the CREATE TABLE and ALTER TABLE statements
to physically store computed columns in the table. Their values are
updated when any columns that are part of their calculation change. By
marking a computed column as PERSISTED, you can create an index on a
computed column that is deterministic but not precise. Additionally,
if a computed column references a CLR function, the Database Engine
cannot verify whether the function is truly deterministic. In this
case, the computed column must be PERSISTED so that indexes can be
created on it. For more information, see Creating Indexes on Computed
Columns.
Don't need to insert Column C, You can easily get Column C using Select Statement.
like this.
select A,B,cast(Cast(A as varchar(max))+cast(B as varchar(max)) as
varchar(max)) as C from Your_Table_Name
If you really need to insert column C, then you have to run insert and Update query at the same time to inset value in the C column of the table.
Like:
insert into Table_Name(B) values('33');Select IDENT_CURRENT();
--you'll get the inserted Identity.
--now run the Update query for Identity you get from the insert query.
Sample.
create table #tab1
(
Id bigint identity(1,1) primary key,
a int,
b varchar(50)
)
insert into #tab1(a) values(88);
declare #id1 as bigint set #id1=(select SCOPE_IDENTITY());
update #tab1 set b=cast(id as varchar(max))+cast(a as varchar(max)) where Id=#id1
I want a bigint ID column for every row of data that i insert into a table. I want Sql server to generate the numbers. I tried to create a table with a bigint column ID. I want this to be autoincrement with the first value as 1. I tried using [ID] [bigint] AUTO_INCREMENT NOT NULL, in my create table statement, but I got the error - Incorrect syntax near 'AUTO_INCREMENT'. How do I do this ?
Can you not just declare it as an IDENTITY column:
[ID] [bigint] IDENTITY(1,1) NOT NULL;
The 1,1 refers to the start index and the amount it is being incremented by.
NOTE: You do not have to provide a value for the ID column when you do an insert. It will automatically choose it. You can modify these values later if required.
EDIT:
Alternatively, you can use a stored procedure to handle all the inserts.
Example:
Stored Procedure will take in variables as you would a normal insert (one variable for every column). The logic within the stored procedure can select the max value currently existing in the table and choose that as its max value.
DECLARE #yourVariable = SELECT MAX(ID) FROM YourTable
Use #yourVariable as your insert value. You can increment it or change value as necessary.
