What does DataExtensionRowCount return?

What does DataExtensionRowCount return?

• A. A boolean indicating if rows exist
• B. The sum of a data extension's key values
• C. The maximum value of a numeric column
• D. The number of rows in the data extension

Answer: (D)

DataExtensionRowCount is about measuring how many records are stored in a data extension. A data extension is like a table of rows and columns, and this function returns the exact number of rows in that table. It gives a numeric count, not a boolean, not a sum of key values, and not the maximum value from any column. For example, if a data extension has 250 records, DataExtensionRowCount would return 250. This is useful for controlling loops, validating data volume, or making decisions based on how many rows exist, rather than inspecting individual fields.
