我不完全确定为什么会这样.当我运行命令时:
ALTER TRIGGER ORIGDV87.UPDATE_TEAM_GROUP_TRIGGER DISABLE/ENABLE
我可以看到它如何改变触发器.我试图从java以编程方式执行此操作:
private void trigger_alter(Connection con, String flag) throws Exception
{
Query query = new Query(con);
String selectSql = "select table_owner, trigger_name from user_triggers";
Query queryTrg = new Query(con);
query.executeQuery(selectSql);
while(query.next()) {
int i = 0;
String table_owner = query.getColValue("table_owner");
String trigger_name = query.getColValue("trigger_name");
String triggerSql = "ALTER TRIGGER " + table_owner + "." + trigger_name + " "+ flag ;
System.out.println( triggerSql);
queryTrg.executeQuery(triggerSql);
}
log_obj.FmtAndLogMsg("All triggers have been " + flag+ "D");
}
我得到此异常:2013/02/26 10:38:56.795 TableConverter:发生错误main():java.lang.Exception:执行查询时出错:ALTER TRIGGER XXXX.UPDATE_TEAM_GROUP_TRIGGER DISABLE error = java.sql.SQLException:ORA-01003 :没有语句解析
它是一个oracle数据库,我在Solaris机器上尝试这个.
解决方法:
更换
queryTrg.executeQuery(triggerSql);
同
con.createStatement().execute(triggerSql);
但是,批量处理ALTER TRIGGER语句会更好:
private void trigger_alter(Connection con, String flag) throws Exception
{
Query query = new Query(con);
String selectSql = "select table_owner, trigger_name from user_triggers";
Statement trgStmt = con.createStatement();
query.executeQuery(selectSql);
while(query.next()) {
int i = 0;
String table_owner = query.getColValue("table_owner");
String trigger_name = query.getColValue("trigger_name");
String triggerSql = "ALTER TRIGGER " + table_owner + "." + trigger_name + " "+ flag ;
System.out.println( triggerSql);
trgStmt.addBatch(triggerSql);
}
trgStmt.executeBatch();
log_obj.FmtAndLogMsg("All triggers have been " + flag+ "D");
}
