While I think this is primarily a mysql syntax problem I have asked on the
mysql forum but not got a reply. I am trying using php to set up a system for
loading a new data base using the Load Data Infile statement. I could not get
it to work properly with php so I thought I would try some command line test.
Does anyone know the loaction of a suitable php script that would handle a
list of files and tables for loading into a database (preferably doing an
initial dummy run using temporary tables with an error report). If not when I
get this wretched syntax issue solved I guess I might have one available
fairly soon.
Here are my notes:
This exercise was a test in preparation for a plan to use Load Data Infile for
initallising a new database comprising over 80 tables. The database currently
has no data. The first field is auto-increment.
What am I doing wrong here?
If I cannot do it using Load Data Infile what alternatives would you suggest?

Here is the content of the first file created as a text file using editor

I then realized my obvious mistake two "'"s in the third field on line two. I
removed "REPLACE" from the command and ran it again:

Any ideas?
