It supports many protocols and tends to be installed by default on many Unix-like operating systems. Because of its general availability, it is a great choice for when you need to download a file to your local system, especially in a server environment.
Downloading files off of the Internet can be dangerous, so be sure you are downloading from reputable sources. Out of the box, without any command-line arguments, the curl command will fetch a file and display its contents to the standard output. Fetching a file and display its contents is all well and good, but what if you want to actually save the file to your system? You can check on things with the cat command:. Execute the following command to download the remote robots.
Primary key If the table contains a primary key field, the source file must contain a column that contains values that are compatible with the primary key field.
In addition, the imported key values must be unique. If an imported record contains a primary key value that already exists in the destination table, the import operation displays an error message. You must edit the source data so that it contains unique key values and then start the import operation again. Indexed fields If the Indexed property of a field in the table is set to Yes No Duplicates , the corresponding column in the source text file must contain unique values. Choose the steps that match your Access version:.
To store the data in a new table, select Import the source data into a new table in the current database. You will be prompted to name this table later. To append the data to an existing table, select Append a copy of the records to the table and then select a table from the drop-down list. Note: To link to the data source by creating a linked table, see the section Link to a text file , later in this article.
Access scans the contents of the file and recommends how the file should be organized. If the file uses a delimiter to separate the fields, ensure that the Delimited option is selected.
If the file has fixed-width fields, ensure that the Fixed Width option is selected. If you are unclear about whether your file has fixed-width or delimited fields, see the previous section, Prepare the source file. Note: If the source text file contains tabs or other special characters, these are represented in the Import Text Wizard as small boxes between the columns of data.
The information that the wizard displays depends on whether you select the Delimited option or the Fixed-Width option. Select or specify the character that delimits the field values - Tab, Semicolon, Comma, Space, or Other. If the file users a text qualifier, in the Text Qualifier box, select either the double quotation mark " or the single quotation mark '. If the first row of the source file contains field names, select the First Row contains Field Names check box.
Then, click Next. The wizard displays the contents of the file. If Access detects a columnar structure in the data, it places vertical lines in the data to separate the fields. Review the structure suggested by the wizard and, if necessary, follow the instructions on the wizard page to add, remove, or adjust the lines. If you chose to append the data, skip to step If you are importing the data to a new table, click Next. At this point, you should review the field properties displayed in the wizard.
Note: The wizard page on which you can specify information about fields you are importing is not displayed if you are appending records to an existing table. Click a column in the lower half of the wizard page to display the corresponding field's properties.
Review and change, if you want, the name and data type of the destination field. Access reviews the first 25 rows in each column to suggest the default data type for the corresponding field. If there are different types of values, such as text and numeric values, in the first 25 rows of a column, the wizard suggests a data type that is compatible with all or most of the values in the column — that is often the Text data type.
Although you can choose a different data type, remember that values that are not compatible with the data type you choose are either ignored or converted incorrectly. For more information about how to correct missing or incorrect values, see the section Troubleshoot missing or incorrect values in an imported table , later in this article. To create an index on the field, set Indexed to Yes. To altogether skip a source column, select the Do not import field Skip check box.
Then click Next. If the records are being added to a new table, the wizard prompts you to specify a primary key for the table. If you select Let Access add primary key , Access adds an AutoNumber field as the first field in the destination table, and automatically populates it with unique IDs, starting with 1. Click Next. Access displays the final page of the wizard. If you are importing records into a new table, specify a name for the destination table.
In the Import to Table box, type a name for the table. If the table already exists, a prompt asks you whether you want to overwrite the existing contents of the table. Click Yes to continue or No to specify a different name for the destination table.
What is the Advanced button used for? The Advanced button in the Import Text Wizard allows you to create or open an import specification in the format used by earlier versions of Access. Unless you have import specifications from earlier versions of Access before Access , we recommend that you do not use the Advanced button. Instead, if you want to save the details of this import operation, you can learn more about this procedure in the next section.
Access attempts to import the data. If any of the data is imported, the wizard displays a dialog box that tells you the status of the import operation. Conversely, if the operation completely fails, Access displays the error message An error occurred trying to import file. Open the destination table in Datasheet view. Compare the data in the table with the source file, and make sure the data appears to be correct. For information on how to save the details of your import into a specification that you can reuse later, see the article Save the details of an import or export operation as a specification.
For information on how to run saved import specifications, see the article Run a saved import or export operation. For information on how to schedule specifications to run at specific times, see the article Schedule an import or export operation. For information on how to change a specification name, delete specifications, or update the names of source files in specifications, see the article Manage Data Tasks.
If you see the message An error occurred trying to import file , the import operation completely failed. Conversely, if the import operation displays the page that prompts you to save the details of the operation, the operation managed to import all or some of the data. The status message also mentions the name of the error log table that contains the description of any errors that occurred during the import operation.
It is important to note that even if the status message indicates a successful operation, you should review the contents and structure of the table to ensure that everything looks correct before you start using the table. Open the destination table in Datasheet view to see if all the data was successfully added to the table. You should then open the table in Design view to review the data type and other property settings of the fields. Tip: While troubleshooting, if you find just a few missing values, you can add them directly to the table in Datasheet view.
On the other hand, if you find entire columns or large number of values either missing or not imported properly, correct the problem in the source file.
When you think you have corrected all known problems, repeat the import operation. Access does not support importing multiple values in a field. The list of values are treated as a single value and placed in a text field, separated by semicolons. If data appears truncated in a column, try increasing the width of the column in Datasheet view. If increasing the width doesn't resolve the issue, the cause might be that the data type of a numeric field is set to Long Integer when it should have been set to Double.
