如何在 grails 中调用带有参数的 Oracle 过程，过程如下所示，

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

我曾尝试调用此程序，但程序遇到错误，您可以查看以下错误消息。

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

贴了一段代码

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
            }

PS：这个问题已经解决，更新描述让这个问题更容易理解。

如果我理解，你的返回类型是number，所以你可以直接使用Sql.NUMERIC。

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