How to pass variable to a query?
Hi All,

How to pass date variable to a query?

I have tried the below one , but it's not working.

ost.ksh

Code:
#!/bin/ksh

v_date=$1
var=$(sqlplus -s $ORACON <<ENDOFSQL
SELECT TO_DATE('$v_date','DD-MON-YYYY'),-1) FROM DUAL;
exit;
ENDOFSQL
)
#End

I have executed as below.

Code:
ksh ost.ksh 20150612

Please help me.

Thanks.

#End

The single quotes will make that a literal `$v_date'
Change it for double quotes to preserve the special meaning of the `$'

Hi,

I have changed single quote to double quote.


I got the below error.

Code:
var SELECT get_dat_function(TO_DATE("20150612","DD-MON-YYYY"),-1) FROM DUAL;
                                                             *
ERROR at line 4:
ORA-06550: line 4, column 62:
PL/SQL: ORA-00904: "DD-MON-YYYY": invalid identifier
ORA-06550: line 4, column 1:
PL/SQL: SQL Statement ignored

Code:
#!/bin/ksh

v_date=$1
var=$(sqlplus -s $ORACON <<ENDOFSQL
SELECT get_dat_function(TO_DATE("$v_date",'DD-MON-YYYY'),-1)) FROM DUAL;
exit;
ENDOFSQL
)
#End

Thanks.

The single qutotes are not the problem.
You pass the date in format YYYYMMDD but the statement expects it to be in format DD-MON-YYYY. And there is a surplus brace.
Code:
v_date=$1
var=$(sqlplus -s $ORACON <<ENDOFSQL
SELECT get_dat_function(TO_DATE('$v_date','YYYYMMDD'),-1) FROM DUAL;
exit;
ENDOFSQL
)
#End

Please post the exact errormessage. When I execute this after setting the ORACON variable it works for me:
Code:
$ sqlplus $ORACON
