The new sql window pastes the sql insert statement and does not respond for a long time. It shows that there are about 10,000 pieces of data inserted in the initialization. As a result, the database is directly stuck, and the efficiency is particularly low. How to solve it? Checked the information online. The following methods can be used:
1. Create a new command window and paste the sql insert statement
At this time, each statement takes about 0.1 seconds, which is more efficient than using the sql window.
2.sqlloader
3.txtloader
4. If you import the data of table A into table B, you can also paste and copy all the selected sql query data and paste it into another table. At this time, pay attention to the correct data to prevent the data from being pasted unsuccessfully due to Chinese and English symbols.
