SQL Converting a varchar to a clob within an SQL union
ziggy25Feb 14 2013 — edited Feb 14 2013Why does oracle not allow the following query
select to_clob(1) from dual
union
select wm_concat(sysdate) from dual;
wm_concat returns a clob. To make both queries in the union have the same type columns i convert the column in the first query to a clob but Oracle gives me an [1]: ORA-00932: inconsistent datatypes: expected - got CLOB error even though both are returning a clob value.
Each of the queries work individually and both return a clob value.
