Passing parameter to mysql stored procedure for Read Database

chakravarthy_ra

I have following statement in the Build SQL query , for 'Read Database' operator, which gives result.

 

call tatvam_opms.volume_change(@customer_id_in=null);

How do i make that input into a prepared statement ? So user can key in 'null' or some other value ?

(null)

Ok so i created a macro with variable as customer_id_in. Then refrenced this in the SP execution as SPName(%{customer_id_in}).

 

It worked. Thanks

Hi @chakravarthy_ra,

 

In order to prevent SQL injection I propose to check prepare statement in the Read Database Operator.

Then you can select a list of parameters (i.e. the values) you want to use in Read Database (see screenshot).

Afterwards you need to replace the macro in the SQL statement with a question mark (?).

 

Best,

Edin
