This property limits the number of characters allowed in the $select query option. If the length of the generated $select parameter exceeds the values specified, the column selection is instead processed client-side. Setting this property to 0 prevents the provider from submitting the $select parameter to the service, which is useful for services that do not support it.

Data Type

Default Value

1000

Remarks

Some APIs require that the list of columns be specified in the $select query parameter. In these cases, it is recommended to use the ExpandAsterisk connection property.

If the MaxSelectLength is exceeded, we will try to default to $select=*. However, APIs that do not support this will trigger a validation error, so customers will need to manually limit the selection list. Depending on the OData version, using $select=* and omitting the $select parameter completely considered the same.
