Is there a workaround? Other than hard coding the 31 Thanks ->->->->->->->->->->->->->->->->->->---<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-< James Thompson 138 Cardwell Hall Manhattan, Ks 66506 785-532-0561 Kansas State University Department of Mathematics ->->->->->->->->->->->->->->->->->->---<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-<-< ^ permalink raw reply [nested|flat] 2+ messages in thread

Try 'exec sql define UID_LEN 31;' > Is there a workaround? Other than hard coding the 31 No need to work around this as the functionality is already there. Please see test1.pgc for an example. Yes, I know I should document all this. :-) Note, that using the exec sql define command is sufficient. You do not need a #define anymore since ecpg will make the replacement.
