I tried googling for this issue but only find how to do it using two tables, as follows,
INSERT INTO tbl_member
SELECT Field1,Field2,Field3,...
FROM temp_table
WHERE NOT EXISTS(SELECT *
FROM tbl_member
WHERE (temp_table.Field1=tbl_member.Field1 and
temp_table.Field2=tbl_member.Field2...etc.)
)
This worked for one scenario,But now my interest is to upload data directly from the program itself without using two tables. What i want is to upload the data which is not in the table. The sql i had in my head was like the following,
INSERT INTO tbl_member (SensorIdValue, DataTimeValue, DataInValue, IncompleteValue, SpiValue, InfoValue)
VALUES ('Sensor.org', '20121017150103', 'eth0','','','')
WHERE (SensorIdValue != 'Sensor.org'AND DataTimeValue != '20121017150103'AND DataInValue != 'eth0'AND IncompleteValue != ''AND SpiValue != ''AND InfoValue != '');
But it's wrong.. may i know the proper way of doing it please, Thank you very much :)

Copying specific rows from a table: We can copy specific rows from a table to insert into another table by using WHERE clause with the SELECT statement. We have to provide appropriate condition in the WHERE clause to select specific rows.
With the help of same structure table. If we want to insert in a table whose structure is same as another table then in the following example it has been demonstrated that how we can have conditional insert i.e. how we can use WHERE clause with INSERT INTO statement.
You can use a select-statement within an INSERT statement to insert zero, one, or more rows into a table from the result table of the select-statement. The select-statement embedded in the INSERT statement is no different from the select-statement you use to retrieve data.
When inserting a single row into the MySQL table, the syntax is as follows: INSERT INTO table_name(column_1,column_2,column_3) VALUES (value_1,value_2,value_3); In the INSERT INTO query, you should specify the following information: table_name : A MySQL table to which you want to add a new row.
INSERT syntax cannot have WHERE clause. The only time you will find INSERT has WHERE clause is when you are using INSERT INTO...SELECT statement.
The first syntax is already correct.
