当我尝试从Oracle的.net提供程序或Microsoft oracle提供程序在我们的oracle数据库上运行程序包时,它给出了以下错误:
{"ORA-06550: line 1, column 7:\nPLS-00221: 'BEGIN_TRANSACTION' is not a procedure or is undefined\nORA-06550: line 1, column 7:\nPL/SQL: Statement ignored"}
这是我的C#代码:
OracleConnection cn = new OracleConnection(connectionString);
OracleCommand cmd = new OracleCommand();
cmd.Connection = cn;
cmd.CommandText = "DOTNET.SYSTEM_CRUD.BEGIN_TRANSACTION";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("p_user_id", OracleDbType.Decimal, ParameterDirection.Input).Value = 4720;
cmd.Parameters.Add("p_commt", OracleDbType.Varchar2, ParameterDirection.Input).Value = "TEST";
//cmd.Parameters.Add("return_value", OracleDbType.Decimal).Direction = ParameterDirection.ReturnValue;
cmd.ExecuteNonQuery();
这是我的包装定义:
Function Begin_Transaction ( p_user_id IN NUMBER,
p_commt IN VARCHAR2
)
RETURN Number;
当我取消注释我添加的第三个参数时,我得到一个不同的错误:
{"ORA-06502: PL/SQL: numeric or value error: character to number conversion error\nORA-06512: at line 1"}
答案 0 :(得分:0)
请尝试以下代码:
using (OracleCommand cmd = new OracleCommand())
{
cmd.Connection = cn;
cmd.CommandText = "DOTNET.SYSTEM_CRUD.BEGIN_TRANSACTION";
cmd.CommandType = CommandType.StoredProcedure;
cmd.BindByName = true;
cmd.Parameters.Add(new OracleParameter("p_user_id", OracleDbType.Decimal, 4720, ParameterDirection.Input));
cmd.Parameters.Add(new OracleParameter("p_commt", OracleDbType.Varchar2, "TEST", ParameterDirection.Input));
cmd.ExecuteNonQuery();
}
注释:
请勿原谅using

我从包定义中删除了用户名,并且还为返回值取消注释了我的add参数。
using (OracleConnection cn = new OracleConnection(connectionString))
{
using (OracleCommand cmd = new OracleCommand())
{
cmd.Connection = cn;
cmd.CommandText = "SYSTEM_CRUD.BEGIN_TRANSACTION";
cmd.CommandType = CommandType.StoredProcedure;
cmd.BindByName = true;
cmd.Parameters.Add("p_user_id", OracleDbType.Decimal, ParameterDirection.Input).Value = 4720;
cmd.Parameters.Add("p_commt", OracleDbType.Varchar2, ParameterDirection.Input).Value = "TEST";
cmd.Parameters.Add("return_value", OracleDbType.Decimal).Direction = ParameterDirection.ReturnValue;
cmd.ExecuteNonQuery();
