texte = Marc, I have been doing this a lot. I have found that its easiest to load the entire contents via INFILE, takes a second. However, depending on your tables data types, you need to prep the webcat data. For instances, make sure dates are in correct format, make sure your columns are large enough to hold the webcat data, etc.. Also, make sure you import the data into the correct charset. For migrating to MySQL from webcat, I have found it best to setup the tables, write migration scripts, then upon rollout execute your scripts to populate your data. Your scripts will clean, prep, and load your data into the tables via select statements. Even here you have the option to do one large SELECT using commas to separate your value groups SELECT (value1, value2, value3,etc),(value1, value2, value3,etc),etc.. OR you can execute a select for each row. Its up to you. Hope this helps.
