This page intentionally left blank INTRODUCTION PL/SQL New Features in Oracle 11g Oracle 11g has introdu Code 128A for Java ced a number of new features and improvements for PL/SQL. This introduction briefly describes features not covered in this book and points you to specific chapters for features that are within scope of this book. The list of features described here is also available in the What s New in PL/SQL section of the PL/SQL Language Reference manual offered as part of Oracle help available online.

The new PL/SQL features and enhancements are as follows:. . Enhancements to regu lar expression built-in SQL functions . SIMPLE_INTEGER, SIMPLE_FLOAT, and SIMPLE_DOUBLE datatypes .

CONTINUE statement . Sequences in PL/SQL expressions . Dynamic SQL enhancements .

Named and mixed notation in PL/SQL subprogram invocations . Cross-session PL/SQL function result cache . More control over triggers .

Compound triggers . Database resident connection pool . Automatic subprogram inlining .

PL/Scope . PL/SQL hierarchical profiler . PL/SQL native compiler generates native code directly.

Enhancements to Regular Expression Built-In SQL Functions In this release Oracle has introduced a new regular expression built-in function, REGEXP_COUNT. It returns the number of times a specified search pattern appears in a source string..

xviii Introduction FOR EXAMPLE SELECT REGEXP_COUNT (" Oracle PL/SQL By Example Updated for Oracle 11g", "ora", 1, "i") FROM dual; REGEXP_COUNT("ORACLEPL/SQLBYEXAMPLEUPDATEDFORORACLE11G","ORA",1,"I") -------------------------------------------------------------------2. The REGEXP_COUNT funct awt Code 128 Code Set B ion returns how many times the search pattern "ora" appears in the source string "Oracle PL/SQL...

" 1 indicates the position of the source string where the search begins, and "i" indicates case-insensitive matching. The existing regular expression built-in functions, REGEXP_INSTR and REGEXP_SUBSTR, have a new parameter called SUBEXPR. This parameter represents a subexpression in a search pattern.

Essentially it is a portion of a search pattern enclosed in parentheses that restricts pattern matching, as illustrated in the following example.. FOR EXAMPLE SELECT REGEXP_INSTR (" barcode 128 for Java Oracle PL/SQL By Example Updated for Oracle 11g", "((ora)(cle))", 1, 2, 0, "i") FROM dual; REGEXP_INSTR("ORACLEPL/SQLBYEXAMPLEUPDATEDFORORACLE11G",...

) -----------------------------------------------------------38. The REGEXP_INSTR funct ion returns the position of the first character in the source string "Oracle PL/SQL " corresponding to the second occurrence of the first subexpression "ora" in the seach pattern (ora)(cle). 1 indicates the position of the source string where the search begins, 2 indicates the occurrence of the subexpression in the source string, 0 indicates that the position returned corresponds to the position of the first character where the match occurs, and "i" indicates case-insensitive matching and REGEXP_SUBSTR..
