【问题描述】：

OracleDataAdapter.Fill 抛出异常：“ORA-00933：SQL 命令未正确结束”。根据许多帖子，通常的罪魁祸首是末尾的一些空格或分号。我复制了语句并在Oracle“Sql Developer”上执行，它可以工作..

这是我的代码（有点）

var stmt = "SELECT fmly.fmly_id, fmly.fmly_key, fmly.fmly_db_view_nm, MI_DBUMS_UTIL.GET_BASELINE_TABLE_NAME(fmly.fmly_id) blTableName " +
                                    "FROM mi_families AS fmly WHERE fmly.fmly_type_cd = 'ENFA' " +
                                    "AND fmly.fmly_id not in (SELECT fmly_id from mi_exclude_families WHERE context_cd = 'REVERT') " +
                                    "AND EXISTS " + "(SELECT 1 FROM mi_entities_bl AS enty_bl WHERE fmly.fmly_id = enty_bl.fmly_id);";    

var conn = new OracleConnection("<connection string>");
var cmd = new OracleCommand(stmt, conn)
IDataAdapter adapter = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();

conn.Open();
cmd.CommandTimeout = 0;
adapter.Fill(ds)

有人可以帮我解释引发异常的原因吗？

【问题讨论】：

去掉末尾引号内的分号并测试查询。

【参考方案1】：

试试这个？

var stmt = "SELECT fmly.fmly_id, fmly.fmly_key, fmly.fmly_db_view_nm, MI_DBUMS_UTIL.GET_BASELINE_TABLE_NAME(fmly.fmly_id) blTableName " +
                                    "FROM mi_families AS fmly WHERE fmly.fmly_type_cd = 'ENFA' " +
                                    "AND fmly.fmly_id not in (SELECT fmly_id from mi_exclude_families WHERE context_cd = 'REVERT') " +
                                    "AND EXISTS " + "(SELECT 1 FROM mi_entities_bl AS enty_bl WHERE fmly.fmly_id = enty_bl.fmly_id)";    

var conn = new OracleConnection("<connection string>");
var cmd = new OracleCommand(stmt, conn);
IDataAdapter adapter = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();

conn.Open();
cmd.CommandTimeout = 0;
adapter.Fill(ds);

删除 SELECT 语句末尾的分号，它应该可以工作。
