所以这是我得到的错误:ORA-01036:非法变量名称/编号
我正在尝试用这些值更新表格。值不为null,参数中的每个变量都包含值。
查询在Oracle中运行良好(没有参数),但是当我添加参数时,它会给出ORA-01036:非法变量名称/编号。
我几乎尝试了一切,但没有运气!!
using (OracleConnection con = new OracleConnection(cs))
{
const string query =
@"UPDATE ASSOCIATED_CENTERS_INFO
SET DIS_ASSOCIATED_BY = (SELECT ID FROM VC_ADMINISTRATORS WHERE USERNAME = ':USER'),
DIS_ASSOCIATION_DATE = SYSDATE,
ACTIVE_YN = 'N',
NOTES = CONCAT(NOTES, '<br>' || SYSDATE || ' ' || (SELECT FIRSTNAME || ',' || LASTNAME FROM VC_ADMINISTRATORS WHERE USERNAME = ':USER') || ': ' || ':COMMENT')
WHERE OSC_ID = :OSCID AND ASSOCIATED_OSC_ID = :ASSOCIATEDOSCID;";
OracleCommand cmd = new OracleCommand(query, con);
cmd.CommandType=CommandType.Text;
cmd.Parameters.AddWithValue(":USER", userName);
cmd.Parameters.AddWithValue(":COMMENT", comment);
cmd.Parameters.AddWithValue(":OSCID", selectedIdOnMap);
cmd.Parameters.AddWithValue(":ASSOCIATEDOSCID", selectedIdOnListBox);
con.Open();
cmd.ExecuteNonQuery();
}
答案 0 :(得分:2)
删除围绕某些参数添加的单引号:
':USER', ':COMMENT' ...
答案 1 :(得分:0)
将所有表名和列名放在引号中:“MY_TableName”: 像:
@"UPDATE ""ASSOCIATED_CENTERS_INFO""
SET ""DIS_ASSOCIATED_BY "" = .......
并从参数中删除引号。
