Execute Queries in Oracle with Dynamic input in where clause -


i have dept(deptno, dname, loc) table data.

i query departments search key dname.

i trying below, not working. can please suggest me. pretty new oracle.

dynamicdeptname varchar2(30):= 'cco'; execute immediate 'select * dept dname '%' || dynamicdeptname || '%'

  1. use bind variables, easier better (more efficient , secure)

  2. single quotes need doubled-up inside single-quoted string.

example:

 execute immediate    'select * dept dname ''%'' || :dname || ''%'''    dept_rec    using dynamicdeptname;

or use q-quote syntax avoid need double-up quotes:

execute immediate    q'[select * dept dname '%' || :dname || '%']'    dept_rec   using dynamicdeptname;
