I need to write an insert
statement into a table the columns looks like this
demandtypeid
(PK, FK, int, not null
)characvalueid
(PK, FK, int, not null
)percentage
(int null
)lastuser
(varchar(100), null
)lastedited
(datetime, null
)
Here is the INSERT
statement. Notice the there is not values at the
value( , , 'Bob')
as I think that’s where the auto-increment command should go
insert into tr_demandtypecharac(demandtypeID, characvalueid, lastuser)
values( , , 'Bob')
Please help with a simple little statement
I just want to know how to manually insert into this table
Here’s my table structure:
CREATE TABLE [dbo].[tr_demandtypecharac](
[demandtypeid] [int] NOT NULL,
[characvalueid] [int] NOT NULL,
[percentage] [int] NULL,
[lastuser] [varchar](100) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[lastedited] [datetime] NULL,
CONSTRAINT [PK_tr_dtc_pkey] PRIMARY KEY CLUSTERED
(
[demandtypeid] ASC,
[characvalueid] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
ALTER TABLE [dbo].[tr_demandtypecharac] WITH CHECK
ADD CONSTRAINT [FK_tr_dtc_cvid]
FOREIGN KEY([characvalueid]) REFERENCES [dbo].[tr_characvalue] ([characvalueid])
ALTER TABLE [dbo].[tr_demandtypecharac] WITH CHECK
ADD CONSTRAINT [FK_tr_dtc_dtid]
FOREIGN KEY([demandtypeid]) REFERENCES [dbo].[tr_demandtype] ([demandtypeid])

Answer
Given the CREATE TABLE
statement you posted, without auto-increment (aka identity) columns, you would insert providing all columns and values, like this:
insert into tr_demandtypecharac(
demandtypeid, characvalueid,
percentage, lastuser, lastedited)
values(2, 3, 80, 'Bob', '01/01/2012')
If, however, you do make them auto-increment by changing the CREATE TABLE
to:
CREATE TABLE [dbo].[tr_demandtypecharac](
[demandtypeid] [int] NOT NULL IDENTITY(1,1),
[characvalueid] [int] NOT NULL IDENTITY(1,1),
[percentage] [int] NULL,
[lastuser] [varchar](100) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[lastedited] [datetime] NULL,
CONSTRAINT [PK_tr_dtc_pkey] PRIMARY KEY CLUSTERED
(
[demandtypeid] ASC,
[characvalueid] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
)
Then you would insert providing all non-identity (non-autoincrement) columns like this:
insert into tr_demandtypecharac(
percentage, lastuser,
lastedited)
values(80, 'Bob', '01/01/2012')
However, it is not common to have more than one column as an identity (autoincrement) column, and generally, this column is the only PRIMARY KEY column.
