Question

In my java web application, I am inserting some records into MySql db. I have a column name ‘value’ whose Field type is float. When I insert the following value 76.8653846153846 into db, it gives exception of Data truncated for column ‘value’ at row 1. I changed field type to Double but same message. Any idea?

Field description:

Answer 1

As per the documentation you must define your number type with the level of precision you require.

for your number 76.8653846153846 use

FLOAT(10,13)

The 13 being large enough to handle your .8653846153846

[Edit]

to alter your existing table execute this command substituting your table and column name for mytable and mycolumn respectively

ALTER TABLE mytable MODIFY mycolumn FLOAT(10,13)
