All the columns created in the Table Definition screen will be displayed on the Data screen. On this screen, you can perform the following operations –
- Select Columns
- Import Rows
- Search Data
- Update Row
- Add Row
- Delete Rows
- Bulk Update
- Truncate Table
- Export Data
By default, all the columns in your Mavis table are displayed on the grid. To customize the grid and display only the columns you require, click Select Columns.
On the Select Columns pop-up, click the checkbox alongside the columns you want to view/hide on the grid. You can search for a specific column and also toggle between All and Selected columns.
- Search is case-insensitive.
- At least one column must be selected.
- To select all the columns, on the Select Column pop-up, alongside Column Name, click .
To populate your table with data –
- First, you’ll have to import the CSV source file.
- Map the columns in the CSV file to the corresponding column within the table.
- Then, validate the CSV file. The validations that might show up are Validation Success and Validation Failed.
- Once the status is Validation Success or Validation Failed (Partially), click the Import button. This will start importing the data into the table.
To import a CSV source file to your table –
- Navigate to the Data screen, and on the right of your screen, hover your cursor over the icon, and click Import Rows.
- Then, click Download Sample. The sample file is generated dynamically and it contains the schema names of all the columns created in the Table Schema.
- On the sample CSV file, enter relevant data in the correct data type under each column, and save the file.
- If you are not using the sample CSV file, and are instead creating a CSV file from scratch, then specify the header names (column names) in the first row, and add data across the subsequent rows.
- Click Upload, and add the relevant CSV file.
- Alternatively, you can drag-and-drop the CSV file.
- Once you’re done, click Next.
- The only file format supported is a “.csv” file.
- The maximum file size allowed is 50MB.
- Column with the name ‘__LSQValidationMessage’ or ‘__LSQValidationStatus’ is not allowed in the CSV file.
Once you’ve imported the CSV file, you will have to map it against the corresponding column within the table.
- If the column names in the CSV file are the same as the column names in the table column, then the columns are automatically mapped.
- Else, from the CSV Column Name dropdowns, you must map the columns to the correct Column Name.
- If DateTime columns are present in the Table Schema –
- From the Date/Time format in CSV section, select the same Date/Time/DateTime formats given in CSV File.
- If table schema contains either of Date/DateTime/Time columns, or its combinations, but not all three columns, then in Date/Time format in CSV section, you can choose only those available column formats. Other formats will be disabled.
- Below are the default formats –
- Date – yyyy-MM-dd
- DateTime – yyyy-MM-dd hh:mm:ss
- Time – hh:mm:ss
- If there are no Date/Time/DateTime fields in the table schema, then this section will remain greyed out and inaccessible.
- Once you’re done, click Next.
- CSV column names are case-sensitive.
- Different DateTime fields in the CSV file should follow one uniform format. You cannot upload different format DateTime fields in the same CSV file.
- For example, in your CSV file, you cannot have one column in the dd-MM-yyyy HH:mm:ss format, and another column in the MM/dd/yyyy HH:mm:ss format.
- Date, Time and DateTime fields will be stored in the default formats in the Mavis DB.
- Non-Nullable and Unique columns will be displayed before other columns.
The data in the CSV file will be validated on this screen.
If Validation Success –
If all the row(s) have been successfully validated, you’ll get the Validation Success message. You can choose to continue the CSV file import process by clicking Next.
If Validation Failed –
If one or all the rows have not been successfully validated, you’ll get the Validation Failed message. There are two types of Validation Failed messages you might receive –
- Partially Failed – This means the validation for only a few rows in the CSV file failed, while the remaining rows’ validation was successful.
- Completely Failed – This means the validation for all the rows in the CSV file failed.
To rectify a failed validation –
- You’ll get the following details about the rows that were validated –
- Total Rows
- Success Rows
- Failed Rows
- Here, you can view the rows that failed during validation.
- If you want to ignore the Failed Rows error and proceed with only uploading the Success Rows in the file import process, you can do so by clicking Next.
- To download the failure report, click Failure Report.
- In the Failure Report file, you’ll see two new system-generated columns have been added – “__LSQValidationMessage” and “__LSQValidationStatus”
- The “__LSQValidationMessage” column will state the reason as to why the validation was unsuccessful for that particular row.
- The “__LSQValidationStatus” will display the validation status (“Success” or “Failed”) for that particular row.
- Once you’ve rectified the error in the original CSV file, save the file, and re-upload it from the Source screen.
- If all the rows have been successfully validated, you’ll get the Validation Success message. You can choose to continue the CSV file import process by clicking Next.
All CSV files that are imported are usually queued within our servers. It may take a few minutes for these files to be successfully imported.
In the Summary screen, you’ll get a message stating, “You have successfully imported the file.” This means your file is currently queued for import, and it will be completed within a few minutes. On this screen, you can perform the following actions –

- Initiated – This means the file import has been successfully initiated. This message will be displayed until the file import is completed.
- Validation In-Progress – This means the uploaded file is currently being validated.
- Validation Success – This means the uploaded file contains no errors and is successfully validated.
- Validation Failed – This means the uploaded file contains errors, and the validation was unsuccessful. Examples of errors could be a String datatype that has more than 500 characters, an Integer datatype with a decimal value, or if a Coordinate Latitude falls outside of -90 to 90 degrees or any such errors for other datatypes.
Table Operation Queued – The Data Import is in the queue, and the data will be inserted into the table within a few minutes.
Table Operation In-Progress – This means the data is currently being pushed to the table.
Table Operation Failed – This means there was an error processing the CSV file. In the following scenarios, the status will change to Table Operation Failed –
- If the CSV file contains duplicate column names
- If the CSV file is corrupted
- If the CSV file does not contain any data
- If the CSV file is not CSV UTF-8 encoded
- If the CSV file does not contain the “__LSQValidationMessage” or “__LSQValidationStatus” columns
- An error occurred while processing the file
Table Operation Success – This means the data got successfully inserted into the table.
- View data – To view the data that was successfully uploaded (or if the file import is still in progress, then you can view the data that has been successfully imported until then), click View data.
