Description copied from interface: PgqlPreparedStatement

Translates this instance's PGQL statement into a series of SQL statements.

Specified by:

translateStatement in interface PgqlPreparedStatement

Parameters:

parallel - the degree of parallelism to use for query execution

dynamicSampling - the value for dynamic sampling

maxResults - the maximum number of rows returned

matchOptions - additional options used to influence query translation and execution

options - additional options used to influence DDL/DML translation and execution

Returns:

the SQL statements and metadata necessary to execute the provided SQL statement

Throws:

PgqlToSqlException - if a server-side error occurs during translation

oracle.pgql.lang.PgqlException - if a server-side error occurs or this method is called on a closed Statement
