  • Method Details

    • canHandle

      public static boolean canHandle(String url)

    • isSupportedFunction

      public static boolean isSupportedFunction(String funcName)

    • getJDBCType

      public static scala.Option<JdbcType> getJDBCType(DataType dt)

    • isCascadingTruncateTable

      public static scala.Option<Object> isCascadingTruncateTable()

    • getTruncateQuery

      public static String getTruncateQuery(String table, scala.Option<Object> cascade)
      The SQL query used to truncate a table. Teradata does not support the 'TRUNCATE' syntax that other dialects use. Instead, we need to use a 'DELETE FROM' statement.
      Parameters:
      table - The table to truncate.
      cascade - Whether or not to cascade the truncation. Default value is the value of isCascadingTruncateTable(). Teradata does not support cascading a 'DELETE FROM' statement (and as mentioned, does not support 'TRUNCATE' syntax)
      Returns:
      The SQL query to use for truncating a table
