This expression is typically known as a validation rule or constraint. It ensures that only specific values, formats, or ranges are accepted in a field, helping to maintain data integrity and accuracy. By restricting inputs, it prevents errors and ensures that the data collected meets predefined criteria. Such rules are commonly used in databases, forms, and programming to enhance user experience and data quality.
A field property that tests values for accuracy as they are entered into a table is known as "data validation." This feature ensures that the data entered meets specific criteria, such as data type, range, or format, thereby preventing errors and maintaining data integrity. For example, a field may be set to only accept numeric values within a certain range or dates within a specified timeframe. By implementing data validation, users can reduce the likelihood of incorrect data being stored in the database.
A validity check on numeric data ensures that only numbers are entered into a specified field, preventing the input of non-numeric characters or symbols. This type of check helps maintain data integrity by validating that the data conforms to the expected format, such as integers or decimals. It can also include range checks to ensure that the numeric values fall within a predefined set of acceptable limits. Overall, validity checks are crucial for ensuring that the data entered into a system is accurate and usable.
The amount of characters that can be stored in each text field is commonly referred to as the "character limit." This limit defines the maximum number of characters, including letters, numbers, and special symbols, that can be entered into that field. Character limits are often set to ensure data integrity and manage storage efficiently.
To correct an error due to a misspelled field name in an expression, first, identify the correct spelling of the field name by referencing the data schema or documentation. Then, update the expression by replacing the misspelled field name with the correct one. After making the correction, re-evaluate the expression to ensure it produces the desired results and check for any further errors. Finally, test the updated expression in the relevant context to confirm its accuracy.

Entry
A field is a box in which data are entered. The field name is the descriptive name given to a field to identify the type of data and to differentiate it from other fields. For example, the field in which an address is entered would probably have the field name "Address".

This limit defines the maximum number of characters, including letters, numbers, and special symbols, that can be entered into that field. Character limits are often set to ensure data integrity and manage storage efficiently.
When referencing field names within an expression, you should surround the field name with curly braces {} to ensure proper identification and interpretation by the system.
By using Field Properties, in particular the Input Mask and formatting options.
The insert will error due to the field definition of "number".
