NAME

DBIx::SQLEngine::Driver::Oracle - Extends SQLEngine for DBMS Idiosyncrasies

SYNOPSIS

  my $sqldb = DBIx::SQLEngine->new( 'dbi:oracle:test' );
  
  $hash_ary = $sqldb->fetch_select( 
    table => 'students' 
    limit => 5, offset => 10
  );

DESCRIPTION

This package provides a subclass of DBIx::SQLEngine which compensates for Oracle's idiosyncrasies.

sql_limit

Adds support for SQL select limit clause.

do_insert_with_sequence

  $sqldb->do_insert_with_sequence( $sequence_name, %sql_clauses ) : $row_count

Implemented using _seq_do_insert_preinc and seq_increment.

seq_increment

  $sqldb->seq_increment( $table, $field ) : $new_value

Increments the sequence, and returns the newly allocated value.

sql_detect_any

  $sqldb->sql_detect_any : %sql_select_clauses

Implemented using Oracle's "select 1 from dual".

sql_detect_table

  $sqldb->sql_detect_table ( $tablename )  : %sql_select_clauses

Implemented using Oracle's "select * from $tablename limit 1".

dbms_create_column_types

  $sqldb->dbms_create_column_types () : %column_type_codes

Implemented using Oracle's blob and number types.

Portability: Note that this capability is currently limited, and additional steps need to be taken to manually define sequences in Oracle.

dbms_create_column_text_long_type

  $sqldb->dbms_create_column_text_long_type () : $col_type_str

Implemented using Oracle's clob type.

recoverable_query_exceptions

  $sqldb->recoverable_query_exceptions() : @common_error_messages

Provides a list of error messages which represent common communication failures or other incidental errors.
