Here are explanations of redirection change of dbisqlc.
After upgrading to IQ15.4, redirection output is empty when using dbisqlc like below.
> dbisqlc -c dsn=xxx -q “select @@version” > output.log
> ls -al output.log — 0 byte (empty) output is generated.
An Output redirection in dbisqlc was changed in IQ 15.2 ESD#3 (CR# 679284).
From 15.2 ESD#3 SQL “output redirection” should be managed with the “>&” syntax instead of “>” at the command line like below.
> dbisqlc -c dsn=xxx -q “select @@version >& output.log”
A dbisql redirection’s has not been changed, and dbisqlc is deprecated.
Recommend to use a dbisql not dbisqlc.
If you want to redirect to output file with input file,
you need to use a read statement and enclose the input/output file with double qoute symbol.
And need to change the redirect from > to >& like below.
> dbisqlc -c dsn=xxx -q -nogui “read input.sql >& output_file”
An output_file is generated with above way like below.
[hpita:/gjang]dbisqlc -c dsn=hpita_iqdemo -q -nogui “read a.sql >& a.log”
