这是我的代码,我想删除名为SMS_DATA的FoxPro表的所有数据,我尝试了 ZAP 命令,还尝试了全部删除和带有 USE -table-name的 PACK 命令,但它不起作用,并提供以下异常:
System.Data.OleDb.OleDbException (0x80004005): File must be opened exclusively.
这是我的代码:
string USETBL ="EXECSCRIPT([USE SMS_DATA && Open SMS_DATA table])";
string DELETE="EXECSCRIPT([DELETE ALL])";
string PACK="EXECSCRIPT([PACK])";
OleDbConnection con = new OleDbConnection(conStr);
try
{
OleDbCommand cmd = new OleDbCommand(USETBL, con);
OleDbCommand cmd1 = new OleDbCommand(DELETE, con);
OleDbCommand cmd2 = new OleDbCommand(PACK, con);
con.Open();
err.log("connection opened");
cmd.ExecuteNonQuery();
err.log("table in use");
cmd1.ExecuteNonQuery();
err.log("delete executed.");
cmd2.ExecuteNonQuery();
err.log("pack executed.");
con.Close();
}
catch (Exception e)
{
err.log("Exception:-" + e);
}
答案 0 :(得分:2)
你的第一行应该是:
EXECSCRIPT([USE SMS_DATA EXCLUSIVE && Open SMS_DATA table]);
为了安全起见,我还将接下来的两行更改为:
string DELETE="EXECSCRIPT([DELETE ALL IN SMS_DATA])";
string PACK="EXECSCRIPT([PACK IN SMS_DATA])";
