I have tested the sql statement in pgsql promplt. it works, but it return with 0 row because no record from that sql statement. I guess something go wrong with OpenACS when a query doesn't return a row.
Error: Database operation "1row" failed (exception NSINT, "Query did not return a row.")
Database operation "1row" failed (exception NSINT, "Query did not return a row.")
while executing
"ns_db 1row $db [db_sql_prep $sql]"
invoked from within
"set selection [ns_db 1row $db [db_sql_prep $sql]]..."
invoked from within
"if { $no_prep == 1 } {
set selection [ns_db 1row $db $sql]
} else {
set selection [ns_db 1row $db [db_sql_prep $sql]]
}"
(procedure "database_to_tcl_string" line 3)
invoked from within

invoked from within

Can I know the rigth answer? Thank you for helping me.
