A RAD function that compares two values. If the values are equal or both values are null, the result is true; otherwise, the result is false.

Function

same

Format

same(value1,value2)

The following parameters are valid for this function.

Factors

Use this function to compare arrays and structures, nulls, files, or empty strings.

When using the same function to compare arrays or structures, preface the variable names with denull, as shown in the following example:

not same(denull($filea), denull($fileb))

Return values

• True: same
• False: not same

Examples

same(1,NULL) returns false.

same(NULL,NULL) returns true.

same({},{,}) returns true.

same({1},{1,}) returns true.

same("",NULL) returns false.

The following is another example:

function testdisplayvaluecopy()
{
	var sql = 'select * from cm3r where number="C10001"';
	var file = new SCFile('cm3r');

	var file1 = new SCFile('cm3r');
	var rc = system.functions.fduplicate( file, file1 );
	
	rc = file.doSelect(sql);
	rc = system.functions.same( file, file1 );
	print("file is same as file1 after file.doSelect: ", rc );
	
	rc = file1.doSelect(sql);
	rc = system.functions.same( file, file1 );
	print("file is same as file1 after file1.doSelect: ", rc );
	var vRet = system.functions.set_display_value(file1, "assets", "testbystone", 1);
	
	rc = system.functions.same( file, file1 );
	print("file is same as file1 after set.display.value: ", rc );

	vRet = system.functions.display_value_copy(file, file1);
	
	rc = system.functions.same( file, file1 );
	print("file is same as file1 after display.value.copy: ", rc );
}
testdisplayvaluecopy();

This example returns these results:

file is same as file1 after file.doSelect:  false

file is same as file1 after file1.doSelect:  true

file is same as file1 after set.display.value:  false

file is same as file1 after display.value.copy:  true
