function IncA (a)

{

var b = 3;

a = IncB(b) + a++;

return a;

function IncB(b)

{

b = b + 1;

return b;

}

Converting datatypes

All variables in the Sybase IQ ETL are represented as strings. This may result

in unexpected behavior when working with numeric values. The functions

parseInt() and parseFloat() can be used to convert a string to an integer or a float,

for example:

var a = "123";

var b = "22";

a > b

will return FALSE while

parseInt(a) > parseInt(b)

returns TRUE.

Including files

Use the uScriptLoad(“filename”) function to include external files into a script.

The external file can contain any valid JavaScript constructs, including

functions, thus allowing a kind of reusable code, for example:

uScriptLoad("C:\scripts\myfunc.js");

var a = 11;

var b = 2;

var c = 0;

b = gcd(a, b);

// gcd function defined in C:\scripts\myfunc.js

Using multiple engines to reduce job execution time

The GRID architecture reduces the job execution time by using parallel

execution of projects on multiple distributed engines.

To make use of this scalability you need to:

1 2 ... 70 71 72 73 74 75 76 77 78 79 80 ... 221 222
