Export Parameter : Query

本文介绍了一种在表模式导出时使用QUERY参数来筛选数据的方法。该方法允许用户通过定义SQL WHERE子句来选择要导出的数据子集。文章强调了QUERY参数的限制条件,例如不能用于全量、用户或表空间模式导出,且不适用于直接路径导出等。

This parameter allows you to select a subset of rows from a set of tables when doing

a table mode export. The value of the query parameter is a string that contains a

WHERE clause for a SQL SELECT statement that will be applied to all tables (or table

partitions) listed in the TABLE parameter.

If a table is missing the columns specified in the QUERY clause, an error message

will be produced, and no rows will be exported for the offending table.

Restrictions

n The parameter QUERY cannot be specified for full, user, or tablespace mode

exports.

n The parameter QUERY must be applicable to all specified tables.

n The parameter QUERY cannot be specified in a direct path export (DIRECT=y)

n The parameter QUERY cannot be specified for tables with inner nested tables.

n You cannot determine from the contents of the export file whether the data is

the result of a QUERY export.
