Importing Excel into an Oracle database.

To import Excel into an Oracle database, you can follow these steps: 1. Open the Excel file and select the worksheet to import. 2. Save the data as a CSV file format (Comma Separated Values). In Excel, select “File”> “Save As”, then choose CSV file format. 3. Open Oracle SQL development tool (such as SQL Developer). 4. In the SQL development tool, create a new table to store the data imported from Excel. For example, use the following statement to create a table named “my_table”:

  CREATE TABLE my_table (
     column1 datatype,
     column2 datatype,
     …
   );

5. Use the following statement to import CSV file data into an Oracle table, where “column1”, “column2”, etc. represent the column names and “datatype” represents the data type of the columns.

  SQL> LOAD DATA

   INTO TABLE my_table
   FIELDS TERMINATED BY ','
   OPTIONALLY ENCLOSED BY '"'
   TRAILING NULLCOLS
   (
     column1,
     column2,
     …
   )
   BEGINDATA
   'data1', 'data2', …

In the above, “my_table” represents the target table to import data, “column1”, “column2”, etc. represent the column names of the table, and “data1”, “data2”, etc. represent the data to be imported. Execute the above SQL statement to import data from a CSV file into an Oracle table. Please note that the above steps are only suitable for small-scale data imports. For importing large amounts of data, other methods such as Oracle’s SQL*Loader or third-party data import tools may be needed.
