问题 I use Oracle 12c. I have below table in my DB. CREATE TABLE TEST_T (COL VARCHAR2(4000 CHAR)); I need insert multibyte characters in this table. The character is 3 byte character.

问题 I have a Oracle 12c query that will eventually be used in a BIRT report (in IBM's Maximo Asset Management platform). The query/report will retrieve records as follows: Retrieve workorders based on the parameters that were selected by the user. All of the parameters are optional. For testing purposes, I'm using bind variables as parameters (in Toad for Oracle). It doesn't matter if the workorders are parents, children, or neither. Of the workorders that were retrieved, also select any children
