getRowRestriction()
public String getRowRestriction()
Optional. SQL text filtering statement, similar to a WHERE clause in
a SQL 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 ByteString getRowRestrictionBytes()
Optional. SQL text filtering statement, similar to a WHERE clause in
a SQL 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 |
ByteString | The bytes for rowRestriction.
|
getSelectedFields(int index)
public String getSelectedFields(int index)
Optional. The names of the fields in the table to be returned. If no
field names are specified, then all fields in the table are returned.
Nested fields -- the child elements of a STRUCT field -- can be selected
individually using their fully-qualified names, and will be returned as
record fields containing only the selected nested fields. If a STRUCT
field is specified in the selected fields list, all of the child elements
will be returned.
As an example, consider a table with the following schema:
{
"name": "struct_field",
"type": "RECORD",
"mode": "NULLABLE",
"fields": [
{
"name": "string_field1",
"type": "STRING",
. "mode": "NULLABLE"
},
{
"name": "string_field2",
"type": "STRING",
"mode": "NULLABLE"
}
]
}
Specifying "struct_field" in the selected fields list will result in a
read session schema with the following logical structure:
struct_field {
string_field1
string_field2
}
Specifying "struct_field.string_field1" in the selected fields list will
result in a read session schema with the following logical structure:
struct_field {
string_field1
}
The order of the fields in the read session schema is derived from the
table schema and does not correspond to the order in which the fields are
specified in this list.
repeated string selected_fields = 1;
| Parameter |
|---|
| Name | Description |
index | int
The index of the element to return.
|
| Returns |
|---|
| Type | Description |
String | The selectedFields at the given index.
|
getSelectedFieldsBytes(int index)
public ByteString getSelectedFieldsBytes(int index)
