error:invalid datawindow row/column specified at line 62 in clicked event of abject cb_1 of w_invoicefetch_add

代码是这样写的：
datetime ls_time
string ls_start,ls_end
int ils_start,ils_end,is_id,i

ls_time=dw_1.getitemdatetime(1,"invoicetch_time")
ls_start =dw_1.getitemstring(1,"invoicetch_start")
ls_end =dw_1.getitemstring(1,"invoicetch_end")

select max(invoice_id) into :is_id from invoice;
ils_start=integer(dw_1.getitemstring(1,"invoicetch_start"))
ils_end=integer(dw_1.getitemstring(1,"invoicetch_end"))
if ils_start>is_id then
for i=ils_start to ils_end
insert into invoice(invoice_id,invoice_fetchtime,invoice_estate)
values(:i,:ls_time,'未使用')
using sqlca;
if sqlca.sqlcode <> 0 then
messagebox("提示信息","取得客户信息失败！")
return
end if
next
END IF
if dw_1.update() = 1 then
commit;
messagebox("提示","保存成功！")
w_invoicefetch.dw_1.retrieve()
close(parent)
else
rollback;
messagebox("提示信息","提交数据失败！")
end if

参考技术A 非法行或列，是否访问了不存在的行（如本只有3行，你访问了第5行），是否访问了不存在的列（列名错了）

postgresql 53300错误

1、查看当前库的最大连接数

show max_connections;

2、查看当前数据库的活动连接数

select datname,application_name,pid,state from pg_stat_activity;

3、杀非活动进程

select pg_terminate_backend(pid);

4、修改数据库的最大连接数

~$PGDATA/data/postgres.conf   -->max_connections  -->重启数据库
