Oracle Learn the use of Oracle SQL Loader One: Features of SQL loader Oracle has a number of tools that can be used to migrate, backup, and restore data. But each tool has its own characteristics. For example, exp and IMP can export and export data in the database, which is a good tool for database backup and recovery, so it is mainly used in the hot backup and
export and the use of SQL Loader (SQLLDR)In an Oracle database, we typically use the following methods when replicating or migrating between tables in different databases:1. The record of a table is exported as a semicolon-delimited INSERT statement and then executed into table B2. Create a dblink between the databases and then use CREATE TABLE B as SELECT * from [email protected] where ..., or INSERT INTO
The business data in the group was previously based on the ETL process in the region acquisition-group cleaning-distribution area, and since the group established the software company, the business data required by the subsidiaries must be applied to the group, but the business system's underlying DC did not provide the corresponding data interface. So there's the need to prototype: Get the TXT data file from the remote FTP server regularly and import the data into the local
We all know that lob data processing is very annoying. After the database design is complete, we often need to load test data, which is also annoying for lob. We can use SQL * loader to implement it, following is the control file:Load dataInfile
Label:In practice, the tables in SQL Server need to be imported into Oracle. It is no problem to have previously tried DTS directly with SQL Server. But this time because of the amount of data in tens, so reported insufficient virtual memory. Finally, the solution is to export the TXT file and the Oracle SQLLDR import through SQL Server. One.

For example, exp and IMP can be used to export and export data in the database, which is a good tool for database backup and recovery. Therefore, exp and IMP are mainly used for hot backup and recovery of the database. It has the advantages of high speed, easy to use, and fast. At the same time, it also has some dis
