Re: Self-updating timestamp?

Ted,

it is the NULL keyword in the definition:

tChanged TIMESTAMP(14) NULL,

that spoils the timestamp. Remove that 'NULL'.

"
Beginning with MySQL 4.1.6, you can include the NULL attribute in the definition of a TIMESTAMP column to allow the column to contain NULL values. Before MySQL 4.1.6 (and even as of 4.1.6 if the NULL attribute is not specified), setting the column to NULL sets it to the current timestamp.
"

Best regards,
