查询以处理sql中的单引号对象

Question

我在jdbc中使用了sql查询

SELECT COUNT (COST_CENTER) AS count FROM IMDB1_FINANCE_BUDGET where COST_CENTER='object name'

这工作正常，但我有一些测试对象，如＆＃39; 0654603？在现在开始查询时带有单引号的SSG会计将是

SELECT COUNT (COST_CENTER) AS count FROM IMDB1_FINANCE_BUDGET where COST_CENTER=''0654603 ? SSG '

现在它正在抛出异常

java.sql.SQLException: ORA-00933: SQL command not properly ended

如何处理此类对象

Answer 1

在这种情况下处理单引号的最佳方法是使用Quoting string literal technique

例如， q＆＃39; [＆＃39; SCOTT]＆＃39;

SQL> WITH DATA AS(
  2  SELECT '''SCOTT' nm FROM dual
  3  )
  4  SELECT * FROM DATA WHERE nm = q'['SCOTT]';

NM
------
'SCOTT

SQL>

当然，用单引号＆＃39;＆＃39;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;＆nbsp;

SQL> WITH DATA AS(
  2  SELECT '''SCOTT' nm FROM dual
  3  )
  4  SELECT * FROM DATA WHERE nm = '''SCOTT';

NM
------
'SCOTT

SQL>
