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. The default is -1.

Data Type

int

Default Value

-1

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. The default is -1.
