Question

我正在运行Matlab的几个SQL脚本。在过去的几个月里，没有任何问题。但是，从本周开始，我开始收到以下错误：

使用database.jdbc.connection / exec时出错（第53行）[Microsoft] [ODBC SQL Server驱动程序]连接忙于另一个hstmt的结果

我已经在Matlab上正确安装了我的ODBC驱动程序，并按如下方式运行SQL查询：

%  connect
conn = database('connectionName','user','password');

% I actually alter between two queries, but put the same here as an example
for i=1:2

   querynew  = "SELECT * FROM tbl";   

   results   = exec(conn, querynew); % the error is triggered here
   results   = fetch(results);
   Data      = results.Data;

end

close(conn)

Answer 1

尝试使用close(results)：

关闭光标

for i=1:2

   querynew  = "SELECT * FROM tbl";   

   results   = exec(conn, querynew); % the error is triggered here
   results   = fetch(results);
   Data      = results.Data;
   close(results);

end
