创建临时表后表不存在
我正在创建一个临时表并使用
Hi I am creating a temp table and insert a record using
CREATE TEMPORARY TABLE temp_table_extension_details (
`Id` int NOT NULL,
`model_code` varchar(10),
`model_description` varchar(50),
`eta` varchar(100),
`options` varchar(100),
`order_numbers` varchar(200),
PRIMARY KEY(Id)
);
INSERT INTO temp_table_extension_details (model_code,model_description,eta,options,order_numbers)
VALUES('ABCD','description','eta','abc,bcd,def','123,234,345,456');
我使用 PHPMyadmin 尝试了这个,它说 # 1 行受影响.
I tried this using PHPMyadmin and it says # 1 row affected.
但是当我尝试使用
SELECT * FROM temp_table_extension_details
它给了我一个错误并说
SELECT * FROM temp_table_extension_details
LIMIT 0, 25
MySQL said: Documentation
#1146 - Table 'trans.temp_table_extension_details' doesn't exist .
有什么原因吗,我想创建一个临时表并插入一些数据,稍后我会从中选择所有数据并删除临时表.
Is there any reson for this , i want to create a temp table and insert some data , later i will select all the data from it and delete the temp table .
提前致谢.
推荐答案
临时表仅在连接期间存在.如果您使用一个查询创建它,然后在新连接上执行单独的查询,则它已经消失了.
Temporary tables only exist during the connection. If you create it with one query and then do a separate query on a new connection it is already gone.
