Hi Experts,
load data local infile and insert into <tablename> are the two methods of
inserting data into a mysql table.
Out of the above two method. Is there any faster method of inserting data
into mysql tables.
No. Load Data is the fastest method, unless the data is already stored in
another table.
Tip: Remember when using Load Data, it will be faster if the table is empty
and optimized (no holes) than with a table that has data in it. That's
because the non-unique indexes are built after all of the data has been
loaded. The alternative is to disable the non-unique indexes prior to using
Load Data. Unfortunately there is no way to disable the building of unique
indexes during this process unless you remove the unique index prior to
loading the data and building it later.
Tip: Using Insert will be much slower than Load Data but you can speed it
up by loading dozens of rows using one Insert statement.
Hope these tips help.
