Hi,
I'm inserting  data into a mysql table as below and it works.
However when I add 2 more Null columns to the end of the table, the procedure doesn't work.
I have no problem querying the table with the extra columns added to the query.
Hope you can help.
Thanks

$query = "INSERT INTO competition  (dates,day,type,format,fee,) VALUES
            		
			('".$dates."', '".$day."', '".$type."', '".$format."', '".$fee."')";
  $result = $conn->query($query);

Have you tried the same syntax in the MySQL console?
Have you tried configuring a default value for the new columns, does that correct the behavior?

Hi Garry,
I'm struggling on how to write the query to work in the MYSQL console.... or it doesn't work.

I tried this

INSERT INTO competition  (dates,day,type,format,fee,) VALUES
            		
			(['2011-09-09'], ['sunday'], ['red'], ['green'], ['10'])"

It's to do with the 2 new columns.
If i create a variable, give it a value, change the insert to include the new columns it works.

The column format is as below...I'm sure I'm doing something silly.

encodeme try this query syntax instead:

 
$query = "INSERT INTO competition  (dates,day,type,format,fee) VALUES
            		
			('$dates', '$day', '$type', '$format', '$fee')";
  $result = $conn->query($query);

Open in new window


For starters, you had an extra comma at the end of line 1 after fee...that needs to be removed.

Then, you need to only have 1 set of quotes or single quotes around your variables.  Numeric variables do not need quotes around them...all of the variables are seperated by commas.

Try that code I modified for you and see if it that helps.

Also, you don't need to have your default as NULL as you have the NULL checkbox checked already...if you don't insert any information it's already NULL so remove your default = NULL from the draw column, but make sure you keep the NULL checkbox checked.  Do the same with your other column.

Brilliant .. I'm not sure which bit did it but removing the comma and quotations marks made it work.
Curiously in Mysql ..unless I'm wrong, when you change the default field to none, if the Null is ticked, the default fiield is re-set to Null.
many thanks for the help ..enjoy the points :)
