SQL Query

The following is a non-exhaustive list of links that may be identified between objects saved in the CAST Analysis Service:

Link Type When is this type of link used?
ACCESS READ

Specifies that an object reads a value of another object. For example if a function reads a global variable:

int g_nVar1;
void f()
{
int nVar1 = g_nVar1;
}

C++ Analyzer will generate this Access (Read) link:
WRITE

Specifies that an object modifies another one. For example if a function modifies a global variable:

int g_nVar1;
void f()
{
g_nVar1 = 1;
}

C++ Analyzer will generate this Access (Write) link:
EXEC

Specifies that an object executes another object (method or function). For example if a function calls another function:

void g()
{
f();
}

C++ Analyzer will generate this Access (Exec) link:

Please note that, as a convention, an EXEC link is also used when the definition or declaration of an object invokes a macro. The links is created from the object to the macro.
MEMBER

Specifies that an object accesses a member of another object. For example if a function "g()" accesses a global var "g_pVar" and to one of its members:

struct { int m_n1; }* g_Var;
void g()
{
g_pVar->m_n1 = 1;
}

C++ Analyzer will generate this Access (Member) link:
ARRAY

Specifies that an object accesses another using square brackets ([ ]). For example if a function "g()" accesses a character's array at its first position:

char g_lpBuffer[256];
void g()
{
g_lpBuffer[0] = '\0';
}

C++ Analyzer will generate this Access(Array) link (with the write property also):
BELONG

Represents a parent link between two objects. If "Sample.h" contains the following statement:

class C1
{
public: int foo() {}
};

C++ Analyzer will generate these Belong links:

  • An object always has a "logical" Belong link to its parent (function, class, global variable folder etc.). Furthermore, when the object is defined at the main file level (global variable or function, non-nested class, class method defined at file level), it has a second "physical" link to this implementation file.
  • An object never has more than two parents.
CONTAIN DECLARE
This link type occurs between a file and a Global object when there is also a declaration (forward declaration or external declaration) in addition to the definition itself. For example, between a file and a:
  • Class
  • Structure
  • Enum
  • Union
  • Function or method
  • Variable or class member

This link can be seen in the example below (Zc):
DEFINE
This link type occurs when a method is defined outside the file containing the class definition. The link is created from the file containing the method definition to the class. For example, using the code below:

glob.h

extern int theGlobalVariable;
class theClass
{
void method();
};

glob.cpp

/* header comment */
##include "glob.h"
int theGlobalVariable = 3;
void theClass::method()
{ if(2+2==4);
}

C++ Analyzer will generate the following link (Zf):
FRIEND
Specifies that a class or a function is a friend of a class.

For example if the class "C2" is declared as friend of a new "C3" class:

{
//...
friend class C2;
};

C++ Analyzer will generate this Friend link:
INCLUDE

Represents an inclusion link between two files. If the "Sample.cpp" file contains the following statement:

#include "Sample.h"

C++ Analyzer will generate this Include link:
INHERIT -

Represents an inheritance between two classes or structures. If we define a new class "C2" inheriting from C1 as in following statement:

class C2 : public C1
{ int foo() {}
};

C++ Analyzer will generate following Inherit link:
OVERRIDE
Specifies that a method redefines another method from an inherited class. For example using the previous sample, "C2::foo()" redefines "C1::foo()". So C++ Analyzer will generate this link:
RELY ON

Specifies that an object uses an existing type. If we define a new variable of type "C1" in "Sample.cpp":

C1* g_pVar1;

C++ Analyzer will generate following Rely On link :
USE

Represents a link between a C/C++ object and a database object. For example, if we define a function "f_ExecSql" containing a ProC statement referencing the "Authors" table :

void f_ExecSql()
{
EXEC SQL EXECUTE select * from authors where au_id = 0;
}

C++ Analyzer will generate a SQL Query object plus links:


The following ESQL tags are also supported (non exhaustive list):

  • EXEC SQL ... INSERT
  • EXEC SQL ... UPDATE
  • EXEC SQL ... DELETE
  • EXEC SQL ... SELECT
  • EXEC SQL ... CALL
  • EXEC SQL ... DECLARE ... CURSOR FOR
  • EXEC SQL ... EXECUTE ... END-EXEC

In ESQL tags, links to the following objects will be found (non exhaustive list):

  • Tables
  • Views
  • Synonyms
  • Stored Procedures and Functions
  • Package Procedures and Functions (Oracle)
