-----------------------------
Resolution: Duplicate
Fix Version/s: 2.2.0
> Spark JDBC writer mapping String to TEXT or VARCHAR
> ---------------------------------------------------
>
> Key: SPARK-10101
> URL: https://issues.apache.org/jira/browse/SPARK-10101
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.4.1
> Reporter: Rama Mullapudi
> Fix For: 2.2.0
>
>
> Currently JDBC Writer maps String data type to TEXT on database but VARCHAR
> is ANSI SQL standard hence some of the old databases like Oracle, DB2,
> Teradata etc does not support TEXT as data type.
> Since VARCHAR needs max length to be specified and different databases
> support different max value, what will be the best way to implement.
