ORA-00934: group function is not allowed here

Oracle Tips by Laurent Schneider


Laurent Schneider is considered one of the top Oracle SQL experts and he is the author of the book "Advanced Oracle SQL Programming" by Rampant TechPress.


Question:  I'm trying to insert data into a table. One of the fields (pac_n) is a number and i want to insert a line after the Max Value. However i am getting the error:

ORA-00934: group function is not allowed here


insert into usr_clear_setup & #40;pac_n,pac_acc,pac_mar_ref,pac_ctr_ref,pac_call,pac_broker,pac_msg,pac_acc_de
sername) values(MAX(pac_n) +1,'ABC','DTB','*','*',' ',' ','DDRAX','A','A','FMLLO','0S821','','','','','DDRAX','DDRAX','','');

Answer:  I would try to use sequence to avoid the ORA-00934 error. 

insert into usr_clear_setup(pac_n,pac_acc)
values ((select max(pac_n)+1 from usr_clear_setup),'ABC');
