Question

我之前成功调用了存储过程，但没有输出参数，现在有这样的新程序。

var returntype number; 
begin 
 IZMST_PKG_SOLO_GENERATE_SQL.pro_get_row_cnt(1,181,:returntype); 
end;

当我将此程序称为同伴错误消息时：错误

org.apache.commons.dbcp.DelegatingCallableStatement with address:
    "oracle.jdbc.driver.OracleCallableStatementWrapper@52d0d407" is
    closed.. Stacktrace follows: java.sql.SQLException:

像这样的代码：

Connection conn = dataSource.getConnection()
            Sql sql = new Sql(conn)
            //int test  = sql.call("",)
            sql.call'BEGIN  IZMST_PKG_SOLO_GENERATE_SQL.pro_get_row_cnt(?,?,?); END;',[1L,qryId,Sql.resultSet(OracleTypes.NUMBER)],{dwells-> 
                println dwells
            }

任何熟悉此事的人都可以帮助我吗？提前谢谢。

如果我理解，您的返回类型为number，因此您可以直接使用Sql.NUMERIC。

sql.call '{call IZMST_PKG_SOLO_GENERATE_SQL.pro_get_row_cnt(?,?,?) }',[1L, qryId, Sql.NUMERIC],{ dwells -> 
  println dwells
}

Grails使用输出参数调用存储过程
