使用PRO C预编译时，如何在PL/SQL块用调用存储过程？
存储过程prc_selTest()定义如下：
CREATE OR REPLACE PROCEDURE prc_selTest (inPhone IN CHAR DEFAULT 'null', cityName OUT CHAR) AS
...
目的是输入手机号，查询对应的归属城市，在SQL PLUS中调用示例如下：
-------------------------------------------------------------------------
SQL> list
1DECLARE
2 outValue VARCHAR(20) := '999';
3BEGIN
4 prc_selTest('1330415',outValue);
5 DBMS_OUTPUT.PUT_LINE('cityName:' || outValue);
6* END;
SQL> /
cityName:丹东
PL/SQL procedure successfully completed.
-------------------------------------------------------------------------
在PRO C源文件中的对应PL/SQL块如下：
-------------------------------------------------------------------------
其它代码...
EXEC SQL BEGIN DECLARE SECTION; /*SQL局部变量描述*/
charphoneNum[15];
charcityName[255];
EXEC SQL VAR phoneNum IS STRING(15);
EXEC SQL VAR cityName IS STRING(255);
EXEC SQL END DECLARE SECTION;
其它代码...
EXEC SQL EXECUTE
DECLARE
outValue VARCHAR(20) := '999';
BEGIN
/*********屏蔽该段代码后，预编译正常*********/
prc_selTest(
honeNum,outValue);
/*********屏蔽该段代码后，预编译正常*********/
:cityName:=outValue;
END;
END-EXEC;
其它代码...
-------------------------------------------------------------------------
编译错误提示如下：

请问谁知道如何在PL/SQL块用调用存储过程，最好给一个例子，谢谢。 |
