如何在 Oracle SQL 中处理单引号

How do I insert a record in a column having varchar data type having single quote in it?

Example: first name is ROBERT and last name is D'COSTA

解决方案

Use two single-quotes

SQL> SELECT 'D''COSTA' name FROM DUAL;

NAME
-------
D'COSTA

Alternatively, use the new (10g+) quoting method:

SQL> SELECT q'$D'COSTA$' NAME FROM DUAL;

NAME
-------
D'COSTA
