SQL语句不起作用-“操作符类型冲突：float与日期不兼容”

Question

I'm a new to this field and i have a problem in executing this procedure it gives me this error: "Operand type clash: float is incompatible with date"

create proc store.checks_pro

(
@book_id int ,
@check_no int,
@check_date date ,
@check_status tinyint ,
@check_amount float,
@check_funder_name varchar (30),
@check_cash_type tinyint,
@check_cash_checkno varchar (20),
@check_notes varchar(100),
@check_userid int ,
@insertion_userid int ,
@insertiondate datetime 
)
as
begin
insert into  checks (book_id,check_amount,check_cash_checkno,check_cash_type,check_date,check_funder_name,check_no,check_notes,check_status,check_userid,insertion_userid,insertiondate)
values (@book_id,@check_no,@check_date,@check_status,@check_amount,@check_funder_name,@check_cash_type,@check_cash_checkno,@check_notes,@check_userid,@insertion_userid,@insertiondate)


end

Answer 1

Check your INSERT statement. You are inserting @check_date into check_cash_checkno column.

Answer 2

With the revised error, your problem is obvious. The values are not matching your columns. You are inserting @check_date in to the column check_cash_checkno .

Answer 3

Just going by column and variable names, there seems to be a considerable mismatch in the order you're supplying the parameters:

insert into  checks (
book_id,check_amount,check_cash_checkno,check_cash_type,check_date,check_funder_name,
check_no,check_notes,check_status,check_userid,insertion_userid,insertiondate)
values (
@book_id,@check_no,@check_date,@check_status,@check_amount,@check_funder_name,
@check_cash_type,@check_cash_checkno,@check_notes,@check_userid,@insertion_userid,@insertiondate)

Eg @check_date is aliging with the check_cash_checkno column, @check_notes aligns with check_status , etc.

I would guess that it should be re-written as:

insert into  checks (
book_id,check_amount,check_cash_checkno,check_cash_type,check_date,check_funder_name,
check_no,check_notes,check_status,check_userid,insertion_userid,insertiondate)
values (
@book_id,@check_amount,@check_cash_checkno,@check_cash_type,@check_date,@check_funder_name,
@check_no,@check_notes,@check_status,@check_userid,@insertion_userid,@insertiondate)

This is one of those unfortunate places where SQL fails to live up to the relational ideal that we should reference columns (attributes) by name and not by ordinal position - you have to supply the parameters or values in the VALUES clause in an order that matches the order you gave for the columns of the INSERT statement.

Answer 4

Follow the order to insert value.

    insert into  checks
    (
    book_id,
    check_amount,
    check_cash_checkno,
    check_cash_type,
    check_date,
    check_funder_name,
    check_no,
    check_notes,
    check_status,
    check_userid,
    insertion_userid,
    insertiondate
    )
    values
    (
    @book_id,
    @check_amount,
    @check_cash_checkno,
    @check_cash_type,
    @check_date,
    @check_funder_name,
    @check_no,
    @check_notes,
    @check_status,
    @check_userid,
    @insertion_userid,
    @insertiondate
    )

Simple example to reproduce your error:

create table test
(
sdate date,
roll nvarchar(50)
)
insert into test(sdate,roll) values(1,'2008-2-2') --false

insert into test(sdate,roll) values('2008-2-2',1) --true

Answer 5

INSERT INTO 
checks (book_id,check_amount,check_cash_checkno,check_cash_type,check_date,check_funder_name,check_no,check_notes,check_status,check_userid,insertion_userid,insertiondate)
VALUES    
(@book_id,@check_amount,@check_cash_checkno,@check_cash_type,@check_date,@check_funder_name,@check_no,@check_notes,@check_status,@check_userid,@insertion_userid,@insertiondate)

Many of the inserted values did not match the selected column order.
