Summary: Add getTruncateQuery to JdbcDialect Key: SPARK-22729 URL: https://issues.apache.org/jira/browse/SPARK-22729 Project: Spark Issue Type: New Feature Components: SQL Affects Versions: 2.2.1 Reporter: Daniel van der Ende In order to enable truncate for PostgreSQL databases in Spark JDBC, a change is needed to the query used for truncating a PostgreSQL table. By default, PostgreSQL will automatically truncate any descendant tables if a TRUNCATE query is executed. As this may result in (unwanted) side-effects, the query used for the truncate should be specified separately for PostgreSQL, specifying only to TRUNCATE a single table. This will also resolve SPARK-22717 See PostgreSQL documentation https://www.postgresql.org/docs/current/static/sql-truncate.html This change will still not let users truncate a table with cascade enabled (which would also truncate tables with foreign key constraints to the table). -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
