mysql - How to insert Array[Byte] into binary datatype colunm with slick and mariadb? -


i attempted insert array[byte] binary datatype colunm scala , play framework , slick on mariadb. however, got error , data wasn't inserted.

execution exception [mysqldatatruncation: data truncation: incorrect string value: '\x85\x09\x9b\x08%b...' column 'userid' @ row 1]

the data uuid use java.util.uuid. conversion uuid array[byte] implemented uuidhelper.scala this code.

how can insert array[byte] data database?

my environment this.

database:

mariadb 10.1.16  mariadb [test]> show full columns user; +-----------+--------------+-----------------+------+-----+---------+-------+---------------------------------+---------+ | field     | type         | collation       | null | key | default | | privileges                      | comment | +-----------+--------------+-----------------+------+-----+---------+-------+---------------------------------+---------+ | userid    | binary(16)   | null            | no   | pri | null    |       | select,insert,update,references |         | | firstname | varchar(254) | utf8_general_ci | yes  |     | null    |       | select,insert,update,references |         | | lastname  | varchar(254) | utf8_general_ci | yes  |     | null    |       | select,insert,update,references |         | | fullname  | varchar(254) | utf8_general_ci | yes  |     | null    |       | select,insert,update,references |         | | email     | varchar(254) | utf8_general_ci | yes  |     | null    |       | select,insert,update,references |         | | avatarurl | varchar(254) | utf8_general_ci | yes  |     | null    |       | select,insert,update,references |         | +-----------+--------------+-----------------+------+-----+---------+-------+---------------------------------+---------+

userid colunm uuid.

play-slick configuration:

slick.dbs.default.driver="slick.driver.mysqldriver$" slick.dbs.default.db.driver="com.mysql.jdbc.driver"

play , scala version:

scalaversion := "2.11.7" librarydependencies ++= seq(   "com.mohiva" %% "play-silhouette" % "3.0.2",   "org.webjars" %% "webjars-play" % "2.4.0-1",   "net.codingwell" %% "scala-guice" % "4.0.0",   "net.ceedubs" %% "ficus" % "1.1.2",   "com.adrianhurt" %% "play-bootstrap3" % "0.4.4-p24",   "com.mohiva" %% "play-silhouette-testkit" % "3.0.2" % "test",   specs2 % test,   "com.typesafe.play" %% "play-slick" % "1.0.1",   "com.typesafe.play" %% "play-slick-evolutions" % "1.0.1",   //"com.h2database" % "h2" % "1.4.188",   "mysql" % "mysql-connector-java" % "5.1.39",   cache,   evolutions,   filters )

is byte array being used uuid? if so, suggest generate hex of uuid, 

insert ... (uuid, ...)     values     (unhex(?), ...)

(i don't know correct syntax substitution in slick.)

as side note, uuids terrible scaling.

that is, not try store calling "characters" binary(16). "bytes" ("blob", not "clob") stuff should stored in binary.

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
