MySQL direct INSERT INTO with WHERE clause

Question

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 :)

Answer 1

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.

Answer 2

Example of how to perform a INSERT INTO SELECT with a WHERE clause.

INSERT INTO #test2 (id) SELECT id FROM #test1 WHERE id > 2

Answer 3

you can use UPDATE command.

UPDATE table_name SET name=@name, email=@email, phone=@phone WHERE client_id=@client_id

Answer 4

If I understand the goal is to insert a new record to a table but if the data is already on the table: skip it! Here is my answer:

INSERT INTO tbl_member 
(Field1,Field2,Field3,...) 
SELECT a.Field1,a.Field2,a.Field3,... 
FROM (SELECT Field1 = [NewValueField1], Field2 = [NewValueField2], Field3 = [NewValueField3], ...) AS a 
LEFT JOIN tbl_member AS b 
ON a.Field1 = b.Field1 
WHERE b.Field1 IS NULL

The record to be inserted is in the new value fields.

Answer 5

The INSERT INTO Statement
The INSERT INTO statement is used to insert a new row in a table.
SQL INSERT INTO Syntax

It is possible to write the INSERT INTO statement in two forms.

The first form doesn't specify the column names where the data will be inserted, only their values:

INSERT INTO table_name
VALUES (value1, value2, value3,...)

The second form specifies both the column names and the values to be inserted:

INSERT INTO table_name (column1, column2, column3,...)
VALUES (value1, value2, value3,...)
