Auto Reparse
Many features of the Code Editor, including the Code Explorer window, code completion, tool tip display of program arguments, bracket matching, collapse loops/blocks, and others, rely on automatic parsing of the PL/SQL code and internally generating a symbol table. This parsing occurs when the editor first loads the objects, and it also occurs in the background in order to maintain the symbol table as the user edits the code.
You can also manually trigger a full reparsing (updating of the internal symbol table) at any time by right-click and select Auto Reparse from the shortcut menu. However, when loading a really large script having this option on will slow down SQL Navigator. Hence, to avoid wasting
CPU resources, you should turn this option off when editing large scripts.

Bind Variables
A bind variable is a variable in a SQL statement that must be replaced with a valid value or address of a value in order for the statement to successfully execute.
SQL Navigator 7.2
User Guide
66
Bind variables enable you to use PL/SQL in a SQL*Plus script. They provide a mechanism for returning data from a PL/SQL block so that it can be used in subsequent queries.
The Code Editor supports bind variables; use them the same way as you would use them in SQL*Plus.
Here is an example of how to declare a bind variable:
VARIABLE s_table_name varchar2(30)
To reference a bind variable in a PL/SQL block, preface it with a colon ( : )
BEGIN
:s_table_name := ‘EMPLOYEE’;
END;

Scan Defines/Substitutions
SQL Navigator 7.2
User Guide
67
The Code Editor lets you use substitution variables in SQL statements—similar to the way SQL*Plus handles them.
NOTE:
Turn on Scan Defines/Substitutions when using variables or text that contain the characters &,
&&, or = :[bind variable]. Otherwise, the statements containing the variables will generate an error.
Specifying substitution variables in SQL statements
Use substitution variables for flexible SQL statements. Flexible SQL statements are a powerful way to improve productivity.
Feature Example
CREATE
USER
&&UNAME
IDENTIFIED
BY &PASS;
GRANT ALL
ON EMP TO
&&UNAME;
&&UNAME
Description
Use the & symbol followed by a variable name to specify a substitution variable.
&EMPNUM
An example of a SQL statement demonstrating the use of a substitution variable
SELECT *
FROM EMP
WHERE
EMPNUM =
‘&EMPNUM’;
When you execute this SQL statement, the
Code Editor prompts you to enter the value for the employee name. This allows you to create generic SQL statements that can be reused.
You can use substitution variables in any part of the SQL statement.
SELECT
&COL1,
&COL2
FROM &TAB;
You can use &EMPNUM as a valid substitution variable name.
When you execute this SQL statement, the
Code Editor prompts you to enter the column names, as well as the table name.
You can use this concept to create other types of generic SQL statements or scripts.
One practical application of this concept is creating a generic script for creating user codes at your site.
You can use the double ampersand the same way as the single ampersand with some differences.
When you execute this SQL statement l
The first time the Code Editor encounters the && variable, it looks up the variable to determine whether it has already been defined in either a
DEFINE statement or in a previous && variable.
l
If the variable is defined, Code Editor substitutes the value in the SQL statement.
l
If the variable is undefined, the Code
SQL Navigator 7.2
User Guide
68
Feature Example Description
Editor prompts you to enter the value of the variable, defines the variable for future look-ups, and substitutes the value in the SQL statement.
l
Once a && variable is defined, you are no longer prompted to enter its value in the same session until you UNDEFINE the variable.
DEFINE and UNDEFINE
You can use the terms DEFINE and UNDEFINE to define and undefine numeric and character variables in
SQL scripts.
Statement Example
DEFINE DEFINE EMP_
NAME=‘SCOTT’
DEFINE EMP_NUM=4467
UNDEFINE UNDEFINE EMP_NAME
Description

A character/varchar substitution variable definition uses single quotes.
Undefine a previously defined substitution variable.
TIP:
Alternatively, right click in the editing pane and select SQL Script Options | Substitutions to open the Substitutions dialog.
New Stored Object Dialog
Select the object type:
Procedure A procedure is a sequence of executable statements that performs a particular action.
Procedures can be stored in the database (where they are also executed) and reused; they are then referred to as stored procedures. Stored procedures cannot be embedded in a SQL statement.
Function A function is a block that returns a value. Functions can be stored in the database and reused. Stored functions can be called from within a SQL statement.
Package+Body A package is an encapsulated collection of related schema objects, including modules and other constructs, such as cursors, variables, exceptions, and records. Packages allow procedures, functions, variables, and cursors that share common or related functions to be compiled and stored as a single schema object.
l
Packages allow encapsulation of internal subroutines and variables.
SQL Navigator 7.2
User Guide
69
Type+Body
Trigger l
With packages, you can specify which code is publicly available to programmers and which data should be hidden. In addition, you can implement global variables, data structures, and values; these persist for the duration of a user session.
l
Packages have both a specification and a body. The package specification declares procedures, functions, cursors, and variables.
l
The package body contains the implementation of the public procedures and functions, together with internal and private programs and variables.
Object types are user-defined data types, equivalent to "classes" in object-oriented languages, that may consist of composite data types or collections such as repeating groups or complex record types. Object types may be associated with member functions and procedures that are implemented in PL/SQL. These modules implement the methods of the object type.
Like packages, object types have both a specification and a body.
l
The specification lists the object's attributes and member functions.
l
The body contains the actual code for the methods.
A trigger is a named PL/SQL unit that is stored in the database and executed in response to a specified event that occurs in the database.
TIP:
For each object type, SQL Navigator provides a ready made template or "shell" to make coding easier. You can modify these templates. The template name and location is defined in the opening comments when the new object is created.

PL/SQL Execution Console
From the Execution Console you can select an entry point (for packages), enter the parameter input values, and choose various run options, such as profiling and directing the results to DBMS_OUTPUT.
The Execution Console helps you set various parameters for wrapping an anonymous block around a stored program so that you can execute it. If you generate an anonymous block, the Console assigns a file name to your block in the form: <Schema name>.<procedure name>.STB. If the anonymous block is for a packaged procedure, then the assigned name has an additional component—the entry point.

Working with packages

The Code Explorer graphically displays a tree-structure view of the package currently in the editor. It shows variables, parameters, record structures, types, cursors, and so on.
SQL Navigator 7.2
User Guide
86
The tree-view is synchronized with the editing cursor in the code-editing window, so when you click any package component in the tree-view, you can see the corresponding PL/SQL code in the editing window.
Likewise, as you move the cursor in the editing window, the tree-view changes to show the object corresponding to the PL/SQL code at the cursor location.
Auto Reparse
PL/SQL parsing occurs when the editor first loads objects, and in the background as the user edits the code.
You can also manually trigger a full reparsing (updating of the internal symbol table) at any time by right-click and select Auto Reparse from the shortcut menu. However, when loading a really large script having this option on will slow down SQL Navigator. Hence, to avoid wasting CPU resources, you should turn this option off when editing large scripts.
