尝试向数据库插入行时,SQL语法无效

Question

我收到此错误: System.Data.SqlClient.SqlException (0x80131904): Incorrect syntax near '12'.

该pbkDB.ExecuteNonQuery(dbCommand)行发生错误.

#region Enhancements_Update
private static bool Enhancements_Update(DataRow dr)

   bool inserted = false;

您应该使用sql参数而不是自己构建字符串.

不管怎样,这是你的错误:

UpdateDate {7}, EnactedDate {8}

你错过了=:

UpdateDate = {7}, EnactedDate = {8}
