getRowRestriction()
public abstract String getRowRestriction()SQL text filtering statement, similar to a WHERE clause in a query. Aggregates are not supported.
Examples: "int_field > 5" "date_field = CAST('2014-9-27' as DATE)" "nullable_field is not NULL" "st_equals(geo_field, st_geofromtext("POINT(2, 2)"))" "numeric_field BETWEEN 1.0 AND 5.0"
Restricted to a maximum length for 1 MB.
string row_restriction = 2;
| Returns | |
|---|---|
| Type | Description |
String | The rowRestriction. |
getRowRestrictionBytes()
public abstract ByteString getRowRestrictionBytes()SQL text filtering statement, similar to a WHERE clause in a query. Aggregates are not supported.
Examples: "int_field > 5" "date_field = CAST('2014-9-27' as DATE)" "nullable_field is not NULL" "st_equals(geo_field, st_geofromtext("POINT(2, 2)"))" "numeric_field BETWEEN 1.0 AND 5.0"

string row_restriction = 2;
| Returns | |
|---|---|
| Type | Description |
ByteString | The bytes for rowRestriction. |
getSelectedFields(int index)
