6.1.2 Differences in data formats
When migrating data from MySQL to DB2 UDB, specific data types require high
attention. The
DATETIME
and
TIMESTAMP
data types have the same content in
MySQL and DB2 UDB, but have a different representation. When loading the
exported data into DB2 UDB you have to be aware of the data format.
Binary Large Objects
(
BLOB
data type) usually contain binary data. Exporting of
binary data into text files is not possible. So, if your BLOBs contain binary data,
you have to migrate them in a different way than exporting and loading.
MySQL DATETIME and TIMESTAMP data type format
Both MySQL data types
DATETIME
and
TIMESTAMP
are mapped to the DB2 data
type
TIMESTAMP
. So, exported MySQL application data of these types must be in
a DB2 readable format.
The export format of MySQL
DATETIME
values is `
YYYY MM DD hh:mm:ss
', e.g.
`
2004 01 30 14:21:14
'. Please notice the separators.
The export format of MySQL
TIMESTAMP
values is `
YYYYMMDDhhmmss
', without any
separators between, such as `
20040130142114
'.
The DB2
LOAD
command lets you specify in the filetype modifier clause
TIMESTAMPFORMAT
how the format of
TIMESTAMP
values should be.
