OracleCommand 未正确结束
OracleCommand not ended properly
我有一个查询来检查用户是否存在于数据库中。当我通过 OracleCommand
检查此查询时,它会导致异常并显示 command
未正确结束。
这里是查询:
select count(*) as user_exists
from users
where upper(u_name) = upper('name')
and u_password = DB_PKG_ACCESS.f_encrypt('pass')
and (expiration_date is null or (expiration_date is not null and trunc(expiration_date) >= trunc(sysdate)));
这里是 command
:
OracleCommand cmd = new OracleCommand("select count(*) as user_exists from users where upper(u_name) = upper('name')"
+" and u_password = DB_PKG_ACCESS.f_encrypt('pass')"
+" and(expiration_date is null or(expiration_date is not null and trunc(expiration_date) >= trunc(sysdate)));", con);
cmd.Parameters.Add(new OracleParameter("name", textBox1.Text));
cmd.Parameters.Add(new OracleParameter("pass", textBox2.Text));
我哪里错了?
尝试像这样从 OracleCommand 中的语句末尾取出分号
OracleCommand cmd = new OracleCommand("select count(*) as user_exists from users where upper(u_name) = upper('name')"
+" and u_password = DB_PKG_ACCESS.f_encrypt('pass')"
+" and(expiration_date is null or(expiration_date is not null and trunc(expiration_date) >= trunc(sysdate))) ", con);
我以前也遇到过这个问题....
HTH
尝试去掉查询中的分号(命令对象自动结束)
OracleCommand cmd = new OracleCommand("select count(*) as user_exists from users where upper(u_name) = upper('name')"
+" and u_password = DB_PKG_ACCESS.f_encrypt('pass')"
+" and(expiration_date is null or(expiration_date is not null and trunc(expiration_date) >= trunc(sysdate))); <==== Here remove it", con);
