Grails 調用帶有輸出參數的存儲過程

Question

如何在 grails 中使用參數調用 Oracle 過程，produre 如下所示，

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

我曾嘗試調用此過程，但程序遇到錯誤，您可以查看以下錯誤消息。

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

粘貼了一段代碼

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
            }

PS：這個問題已經解決了，更新一下描述，讓這個問題更容易理解。

Answer 1

如果我理解，您的返回類型是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
}
