    Create new table

    If you choose Create new table, follow these steps.

    1. From the Named Connection drop-down list select a named connection type. There are two types of named connections, file-based and database.

      • Choose the file-based connection for uploading data as TAB files.
      • Choose the SQL-based connection for uploading data as SQL table.

    2. Click to specify the File system path.

      • For file-based connection Spectrum Spatial Analyst displays the root folder. By default, Spectrum Spatial Analyst displays the name of first folder in the list on which the user has the write-access.
      • For SQL-based connection, it shows the list of schemas. For more information see, Browsing the Spatial Repository.
    3. In the Datasource table name field, displays the name of the data source. If the name already exists, you can edit the table name.
    4. In the Named table name field, the name of selected table displays. If the table name already exists, you can edit the name.

    5. Click to specify the path of the repository folder on the Spatial Spectrum server. Your table will be saved in this folder.

      Note: While browsing the repository folder, if you cannot locate a folder, check with your administrator to determine if restrictions have been placed at the file-server level. You must have Write permission to the folder that you select.

    6. Click Upload. You get a message that the files have been uploaded, which means a new table is created on the Spatial repository. If you wish, you can view the new named table by clicking the hyperlink in the message.

      After the file is uploaded, you can choose to create layer and save it to repository with the default layer style or with your custom styles.

    If you choose Replace table, follow these steps.

    1. In the Named Connection field, click to browse the Spatial Spectrum repository and select the named table that you want to overwrite.

      The selected named table should have the same column structure as the table being uploaded.

    2. Spectrum Spatial Analyst detects the Datasource name to which the table belongs and populates the Named connection and Datasource table name fields.
    3. Click Upload. You get a message that the files have been uploaded and the selected named table is updated. If you wish, you can view the updated named table by clicking the hyperlink in the message.
