Thank you very much!
you told me how to do. but I missed the "... defined as UNIQUE ...".
Actually my question is just solved by two step:
First - CREATE UNIQUE INDEX i_recdata ON rec_data (num, di, time1);
Second - INSERT OR REPLACE INTO rec_data (num, di, data, time1, time2,
format) VALUES
Assumptions : Your database scheme contains this declarations
CREATE TABLE data (
num INTEGER,
di CHAR(4),
data CHAR(12),
time1 INTEGER,
time2 INTEGER,
format CHAR(1)
);
CREATE UNIQUE INDEX i_data ON data (
num, di, time1
);
You want to do :

Here are 6 values:

Hi,
what do you mean by "command"? The command line tool takes commands
entered by the user, such as SQL - statements. These do not have
returncodes. If an error occurs, the command line tool will print out
the error message.
The functions of the sqlite3 library have returncodes, but they can
and I think of another question:
how to know the return value of a command IN the command-line mode of
sqlite3?

Yeah!
Thank you very very much!
this way could get my goal. but I am afraid the sql will cause some sqlite3
err?

Hi,
First, you have to declare the index as unique:
CREATE UNIQUE INDEX i_data ON data (num, di, time1);
or - depending on your database design, declare a primary key with these
three fields.
Second, the error message says it all: You supplied three column -
names, but 6 values.

Well you have a column named data and a table named data, but the biggest issue
is you only supplied 3 column names but in the values list you have 6 values.

Thank you a lot!
I created a table:
CREATE TABLE data ( num INTEGER, di CHAR(4), data CHAR(12), time1 INTEGER,
time2 INTEGER, format CHAR(1) );
and create a index:
CREATE INDEX i_data ON data (num, di, time1);
I want to do:
first tell whether there is a record in the table "data" according to

INSERT OR
look up the insert or replace statement, http://www.sqlite.org/lang_insert.html

the first step is to tell if there is the data in the table.
if the answer is not, I want to insert a row of data into the table
if the answer is yes, I need to update the row of data acccording to the
data inputting from me.
