S_USERNAME=:USERNAME AND S_PASSWORD=:PASSWORD";
OracleParameter[] parms = {
new OracleParameter("USERNAME",OracleType.VarChar),
new OracleParameter("PASSWORD",OracleType.VarChar),
};
parms[0].Value = userName;
parms[1].Value = password;
string sql = "SELECT * FROM TBL_C_USER WHERE S_USERNAME=:USERNAME AND S_PASSWORD=:PASSWORD";
这是什么用法?要实现怎样的功能?尤其是S_USERNAME=:USERNAME AND S_PASSWORD=:PASSWORD 很诡异?没见过
