Re: How do I clip a vary length field?

This whole process is invoked through the exit point QIBM_QZDA_SQL2 with format ZDAQ0200.


Upper is 128 bytes because I needed something small enough to test with when I connected via ODBC. We have in production statements exceeding 32k and I only log a set size which would be bigger than 128 but less than 32k

I was trying to simplify the substring of the passed data and though that varying fields would handle it.

I'd guess a pointer problem. How is EZDQLSTL defined, and how's it loaded?

Okay, I am truly lost here. I am missing something really simple. this is a quick test program that fails when called by the exit with RNQ0115 when it does the upper=sqlstuff

RNQ0115 is Length of varying length variable is out of range.

/copy qsysinc/qrpglesrc,ezdaep
Dcl-s pEZDQLSTL pointer inz( %Addr( EZDQLSTL ) );

Dcl-s SQLStuff VarChar(32000: 4) Based( pEZDQLSTL );

Dcl-s Upper Varchar(128);

dcl-pr ODBCEXIT extpgm('ODBCEXITN');
allow char(1);
datain likeds(EZDSQLF2);
end-pr;

dcl-pi ODBCEXIT;
allow char(1);
datain likeds(EZDSQLF2);


allow = *on;
Upper = SQLStuff; // This will truncate to 1024 if needed.

*inlr = *on;

return;
