ORA-06550 第 10 行，第 41 列：PLS-00103：在预期以下情况之一时遇到符号“，”：

Question

我正在从 C# 执行一个匿名 PL/SQL 块，但我收到如下错误：

ORA-06550 第 10 行，第 41 列：PLS-00103：遇到符号“，” 预期以下情况之一时：

我的代码：

OracleDB AppConn = new OracleDB();
OracleDataReader eligiblereader = null;

 string id = "2304502001101";
 long provider = 667;
 long policy = 150;
 DateTime to = Convert.ToDateTime("2015/05/06");
using (OracleConnection con = AppConn.Connection)
{
 OracleCommand cmd = con.CreateCommand();

 cmd.Connection = con;
cmd.CommandText = @"declare 
                  p_id   VARCHAR2;
                  p_policy_id   NUMBER;
                  p_provider_id   NUMBER;
                  p_date        DATE;
                  p_tob         tob_type;
                 begin
                                 pbm_pkg.get_member_tob(p_id,p_policy_id,p_provider_id,p_date,p_tob);
open :refcur for select tob_type.benefit_id from dual;
end;";
OracleParameter p = cmd.Parameters.Add(
                         "rs", OracleDbType.RefCursor,
                         DBNull.Value,
                         ParameterDirection.Output);
 OracleParameter p_id = new OracleParameter();
  p_id.OracleDbType = OracleDbType.Varchar2;
  p_id.Direction = ParameterDirection.Input;
  p_id.Value = id;

OracleParameter p_policy_id = new OracleParameter();
p_policy_id.OracleDbType = OracleDbType.Int64;
p_policy_id.Direction = ParameterDirection.Input;
p_policy_id.Value = policy;

OracleParameter p_provider_id = new OracleParameter();
p_provider_id.OracleDbType = OracleDbType.Int64;
p_provider_id.Direction = ParameterDirection.Input;
p_provider_id.Value = provider;

OracleParameter p_date = new OracleParameter();
p_date.OracleDbType = OracleDbType.Date;
p_date.Direction = ParameterDirection.Input;
p_date.Value = to;
cmd.Parameters.Add(p_id);
cmd.Parameters.Add(p_policy_id);
cmd.Parameters.Add(p_provider_id);
cmd.Parameters.Add(p_date);

    try
    {
    con.Open();

    cmd.ExecuteNonQuery();

eligiblereader = ((OracleRefCursor)cmd.Parameters[4].Value).GetDataReader();

 while (eligiblereader.Read())
 {
  string id = eligiblereader.GetValue(0).ToString();

}
}
catch (Exception ex)
 {
}
finally
 {
con.Close();
}
return View();
        }

命令执行'cmd.ExecuteNonQuery();'时出现错误

我想我在匿名块中遗漏了一些东西。

Answer 1

p_id VARCHAR2;

这肯定是不正确的语法，会引发编译错误。

错误重现：

SQL> DECLARE
  2    p_id VARCHAR2;
  3  BEGIN
  4    NULL;
  5  END;
  6  /
  p_id VARCHAR2;
       *
ERROR at line 2:
ORA-06550: line 2, column 8:
PLS-00215: String length constraints must be in range (1 .. 32767)


SQL>

因此，您必须在 1 .. 32767 之间指定 字符串长度限制。

解决方案：

指定字符串变量所需的长度。

SQL> DECLARE
  2    p_id VARCHAR2(20);
  3  BEGIN
  4    NULL;
  5  END;
  6  /

PL/SQL procedure successfully completed.

SQL>

open :refcur for select tob_type.benefit_id from dual;

您需要为 refcursor 声明绑定变量。

例如，

SQL> var r refcursor
SQL>
SQL> BEGIN
  2    OPEN :r FOR SELECT empno,ename FROM emp;
  3  END;
  4  /

PL/SQL procedure successfully completed.

SQL> print r

     EMPNO ENAME
---------- ----------
      7369 SMITH
      7499 ALLEN
      7521 WARD
      7566 JONES
      7654 MARTIN
      7698 BLAKE
      7782 CLARK
      7788 SCOTT
      7839 KING
      7844 TURNER
      7876 ADAMS

      7902 FORD
