RE: External RE: Base64Decode

Does anyone have an example of getting a base64 BLOB element, over 153,000, from a json using SQL?
Once I have the field I can decode it.

Just not figuring out the secret decoder structure to use.

This code works, but it requires that you fetch into a HEX CCSID field.

This works with both QSYS2.BASE64_DECODE() and systools.base64decode().


DecodedLabel = DecodeLabel( Labelresponse.base64data ) ; If DecodedLabel = *Blank;
//error
Endif;


dcl-proc DecodeLabel;
Dcl-Pi *N Varchar(4096) CCSID(1208);
base64dataLabel Varchar(4096) CCSID(1208);
End-pi;
Dcl-S DecodedHex VarChar(4096) CCSID(*HEX);
Dcl-S DecodedLabel VarChar(4096) CCSID(1208);

// exec sql set :DecodedHex = BASE64_DECODE(:base64dataLabel );

exec sql set :DecodedHex = systools.base64decode( :base64dataLabel );
if sqlcode < 0;
// error
clear DecodedLabel;
return DecodedLabel;
Endif;
// set UTF8 field to value of HEX field
DecodedLabel = DecodedHex;
Return DecodedLabel;

End-proc;
