SQL*Loader loads data in a variety of formats, performs. During execution SQL*Loader produces a. You have control over several. The. control file tells SQL*Loader how to interpret the data file. For example, it. describes the following. The control file's datatype specifications tell SQL*Loader how to interpret. SQL*Loader uses this information when working. ORACLE. ORACLE then converts the data into the datatype specified by the table. However, many options are also available. For example, the instructions can. ID numbers. It is usually read from one or more data. In fixed format, the data is. That is, the. records have a fixed length, and the data fields in those records have fixed.
