Re: HOW TO EXTRACT NUMBER FROM ALPHANUMERIC?

Hi Josh,

Create the below Custom Function in BODS and use it. It shall give you expected result.

Step 1: Create a custom function and name it as CF_Extract_Numbers

Step 2: Declare a parameter and name it as $input_field datatype(256)

Step 3: Change the datatype of parameter Return to varchar(256)

Step 4: Declare Local Variables as shown in left pane of the function editor.

$L_Char - datatype varchar(255)
$L_Counter - datatype int
$L_String - datatype varchar(255)
$L_String_final - datatype varchar(255)
$L_String_Length - datatype int

Step 5: Copy paste the following code in body of the function editor.

# This function is to Extract only numbers from a string.

 

$L_String =$input_field;

$L_String_Length =length( $L_String );

$L_Counter =1;

$L_String_final =null;

 

 

while($L_String_Length>0)

begin

$L_Char =substr( $L_String ,$L_Counter,1);

 

 

if( (ascii($L_Char)>=48 and ascii($L_Char)<=57) )

begin

$L_String_final =$L_String_final||$L_Char;

$L_Counter =$L_Counter+1;

$L_String_Length =$L_String_Length-1;

end

else

begin

$L_Counter =$L_Counter+1;

$L_String_Length = $L_String_Length-1;

end

end

 

Return replace_substr( replace_substr( rtrim_blanks( rtrim_blanks( $L_String_final )),'  ',' '),'  ', ' ');

Step 5: Save this function.

Step 6: Call this function while mapping your field in Query Editor where you want to apply this function.

Example: CF_Extract_Numbers(Table1.INPUT_VAL)

So your function would look like as below in editor.
