Oracle ProC插入值((select ...)) [英] Oracle ProC INSERT INTO VALUES ( (select ...) )

问题描述

在Oracle 10g上运行Pro * C.

Running Pro*C on Oracle 10g.

我正在寻找在insert语句values子句中进行子查询的方法.该sql查询完全有效，并且可以在TOAD内正常运行，但是Pro * C无法解析该查询.

I am looking to do a subquery within an insert statement values clause. This sql query is fully valid and runs within TOAD with no problems, but Pro*C fails to parse the query.

EXEC SQL INSERT INTO TARGET_ATTACHMENT 
      (
          TARGET_ID
          FILENAME
      ) 
      VALUES ( 
         :targetID,
         ( SELECT CREATED_FLAG from TARGET t where t.TARGET_ID = :targetID ) || '.tif'
      )

如果我删除:

( SELECT (CREATED_FLAG || DISPLAY_ID) from TARGET t where t.TARGET_ID = :targetID ) ||**". 

Pro * C编译器可以正常工作，并且一切都可以按预期进行编译和运行.

The Pro*C compiler works and everything compiles and runs as expected.

如果我不删除: Pro * C编译器会引发语法错误.

If I DO NOT remove: The Pro*C compiler throws a syntax error.

1>Error at line 128, column 12 in file d:\SVN\...

这是个问题，因为我希望Pro * C能够在值范围内编译子查询:

This is a problem, as I expect Pro*C to be able to compile subquerys within a values caluse:

即.

INSERT into table1 (col1) values ( (select t2.singleCol from table2 t2 where t2.priKey = :priKey) )

这是Pro * C的预期行为吗?还是应该在values子句中支持子查询?

Is this expected behaviour of Pro*C? or Should it support subqueries within the values clause?

推荐答案

可能将子查询更改为:

( SELECT CREATED_FLAG || '.tif' from TARGET t where t.TARGET_ID = :targetID ) 

我认为我从未见过像您所尝试的那样在子查询中附加任何内容.

I dont think I have ever seen something appended to a subquery the way you were attempting.
