Question

我正在尝试确定列是否是oracle数据库中的主键。

我有以下sql：

SELECT cols.column_name 
FROM all_constraints as cons, all_cons_columns as cols 
WHERE (cols.table_name = 'TABLE_NAME' 
       AND cols.columnName= 'SRC_CODE' 
       AND cons.constraint_type = 'P' 
       AND cons.constraint_name = cols.constraint_name 
       AND cons.owner = cols.owner 
       AND cons.status = 'ENABLED' 
       AND lower(cons.owner)='resmaid') 
ORDER BY cols.table_name

我收到以下错误：

Caused by: java.sql.SQLSyntaxErrorException: ORA-00933: SQL command not properly ended

    at oracle.jdbc.driver.OracleStatement.executeQuery(OracleStatement.java:1477)
    at oracle.jdbc.driver.OracleStatementWrapper.executeQuery(OracleStatementWrapper.java:392)

有一段时间这个sql可能有用，不能记得什么时候（大约2年前）。

这很紧急，因为我需要连接到这个数据库并进行一些数据插入。

提前致谢

Answer 1

我修好了。

两件事。 1.删除表名称别名中使用的“AS” 2. column_name在where子句

中拼写错误

请参阅下文

SELECT cols.column_name
  FROM all_constraints cons,
  all_cons_columns   cols
  WHERE (cols.table_name = 'TABLE_NAME'
    AND cols.column_Name = 'SRC_CODE'
    AND cons.constraint_type = 'P'
    AND cons.constraint_name = cols.constraint_name
    AND cons.owner = cols.owner
    AND cons.status = 'ENABLED'
    AND lower(cons.owner) = 'resmaid')
 ORDER BY cols.table_name;

Answer 2

 SELECT cols.column_name
 --modify FROM all_constraints as cons, all_cons_columns as cols  
FROM all_constraints cons, all_cons_columns cols 
WHERE (cols.table_name = 'TABLE_NAME' 
       --modify AND cols.columnName= 'SRC_CODE'  
       AND cols.column_name= 'SRC_CODE' 
       AND cons.constraint_type = 'P' 
       AND cons.constraint_name = cols.constraint_name 
       AND cons.owner = cols.owner 
       AND cons.status = 'ENABLED' 
       AND lower(cons.owner)='resmaid') 
ORDER BY cols.table_name
