ingres_field_precision — Get the precision of a field

说明

ingres_field_precision ( resource $result , int $index ) : int

ingres_field_precision() returns the precision of a field. This value is used only for decimal, float, and money SQL data types. For detailed information, see the Ingres OpenAPI User Guide, Appendix "Data Types" in the Ingres documentation.

Note: Related Configurations

See ingres.array_index_start in Runtime Configuration

参数

result

The query result identifier

index

index is the field whose precision will be retrieved.

The possible values of index depend upon the value of ingres.array_index_start. If ingres.array_index_start is 1 (the default) then index must be between 1 and the value returned by ingres_num_fields(). If ingres.array_index_start is 0 then index must be between 0 and ingres_num_fields() - 1.

返回值

Returns the field precision as an integer
