The “Column count” setting specifies the number of columns to retrieve from the seed data. If the setting is one, the property is set to a single value. If the setting is greater than one, the property value type depends upon the option chosen for the “Row representation” setting.
- If “Array” is chosen the property is set to an array value, with one array member for each column in the seed data. If there are fewer columns in the seed data than specified in “Column count”, then the extra values in the array are set to null. The array will always be the size specified by “Column count”.
- If “Struct” is chosen, the property is set to a struct value, with one member for each column in the seed data. The “Struct” option can only be used when accessing seed data via URL and the “Column names are in the first row” option is chosen, or when a Repository seed data object is being used.
Note that Struct is available with Seed Data: URL only when the Column names are in the first row box is also checked.
