public static final class PartialResultSet.Builder extends GeneratedMessageV3.Builder<PartialResultSet.Builder> implements PartialResultSetOrBuilder

Partial results from a streaming read or SQL query. Streaming reads and SQL queries better tolerate large result sets, large rows, and large values, but are a little trickier to consume.

addAllValues(Iterable<? extends Value> values)

public PartialResultSet.Builder addAllValues(Iterable<? extends Value> values)

A streamed result set consists of a stream of values, which might be split into many PartialResultSet messages to accommodate large rows and/or large values. Every N complete values defines a row, where N is equal to the number of entries in metadata.row_type.fields.

Most values are encoded based on type as described here.

It is possible that the last value in values is "chunked", meaning that the rest of the value is sent in subsequent PartialResultSet(s). This is denoted by the chunked_value field. Two or more chunked values can be merged to form a complete value as follows:

• bool/number/null: cannot be chunked
• string: concatenate the strings
• list: concatenate the lists. If the last element in a list is a string, list, or object, merge it with the first element in the next list by applying these rules recursively.

• object: concatenate the (field name, field value) pairs. If a field name is duplicated, then apply these rules recursively to merge the field values.

  Some examples of merging:

  Strings are concatenated.

  "foo", "bar" => "foobar"

  Lists of non-strings are concatenated.

  [2, 3], [4] => [2, 3, 4]

  Lists are concatenated, but the last and first elements are merged

  because they are strings.

  ["a", "b"], ["c", "d"] => ["a", "bc", "d"]

  Lists are concatenated, but the last and first elements are merged

  because they are lists. Recursively, the last and first elements

  of the inner lists are merged because they are strings.

  ["a", ["b", "c"]], [["d"], "e"] => ["a", ["b", "cd"], "e"]

  Non-overlapping object fields are combined.

  {"a": "1"}, {"b": "2"} => {"a": "1", "b": 2"}

  Overlapping object fields are merged.

  {"a": "1"}, {"a": "2"} => {"a": "12"}

  Examples of merging objects containing lists of strings.

  {"a": ["1"]}, {"a": ["2"]} => {"a": ["12"]}

  For a more complete example, suppose a streaming SQL query is yielding a result set whose rows contain a single string field. The following PartialResultSets might be yielded:

  { "metadata": { ... } "values": ["Hello", "W"] "chunked_value": true "resume_token": "Af65..." } { "values": ["orl"] "chunked_value": true "resume_token": "Bqp2..." } { "values": ["d"] "resume_token": "Zx1B..." }

  This sequence of PartialResultSets encodes two rows, one containing the field value "Hello", and a second containing the field value "World" = "W" + "orl" + "d".

getValues(int index)

public Value getValues(int index)

A streamed result set consists of a stream of values, which might be split into many PartialResultSet messages to accommodate large rows and/or large values. Every N complete values defines a row, where N is equal to the number of entries in metadata.row_type.fields.

Most values are encoded based on type as described here.

It is possible that the last value in values is "chunked", meaning that the rest of the value is sent in subsequent PartialResultSet(s). This is denoted by the chunked_value field. Two or more chunked values can be merged to form a complete value as follows:

• bool/number/null: cannot be chunked
• string: concatenate the strings
• list: concatenate the lists. If the last element in a list is a string, list, or object, merge it with the first element in the next list by applying these rules recursively.

• object: concatenate the (field name, field value) pairs. If a field name is duplicated, then apply these rules recursively to merge the field values.

  Some examples of merging:

  Strings are concatenated.

  "foo", "bar" => "foobar"

  Lists of non-strings are concatenated.

  [2, 3], [4] => [2, 3, 4]

  Lists are concatenated, but the last and first elements are merged

  because they are strings.

  ["a", "b"], ["c", "d"] => ["a", "bc", "d"]

  Lists are concatenated, but the last and first elements are merged

  because they are lists. Recursively, the last and first elements

  of the inner lists are merged because they are strings.

  ["a", ["b", "c"]], [["d"], "e"] => ["a", ["b", "cd"], "e"]

  Non-overlapping object fields are combined.

  {"a": "1"}, {"b": "2"} => {"a": "1", "b": 2"}

  Overlapping object fields are merged.

  {"a": "1"}, {"a": "2"} => {"a": "12"}

  Examples of merging objects containing lists of strings.

  {"a": ["1"]}, {"a": ["2"]} => {"a": ["12"]}

  For a more complete example, suppose a streaming SQL query is yielding a result set whose rows contain a single string field. The following PartialResultSets might be yielded:

setResumeToken(ByteString value)

public PartialResultSet.Builder setResumeToken(ByteString value)

Streaming calls might be interrupted for a variety of reasons, such as TCP connection loss. If this occurs, the stream of results can be resumed by re-sending the original request and including resume_token. Note that executing any other transaction in the same session invalidates the token.

bytes resume_token = 4;

Parameter
Name	Description
value	ByteString The resumeToken to set.

Returns
Type	Description
PartialResultSet.Builder	This builder for chaining.

setStats(ResultSetStats value)

public PartialResultSet.Builder setStats(ResultSetStats value)

Query plan and execution statistics for the statement that produced this streaming result set. These can be requested by setting ExecuteSqlRequest.query_mode and are sent only once with the last response in the stream. This field will also be present in the last response for DML statements.

Parameter
Name	Description
value	ResultSetStats

Returns
Type	Description
PartialResultSet.Builder

setStats(ResultSetStats.Builder builderForValue)

public PartialResultSet.Builder setStats(ResultSetStats.Builder builderForValue)

Query plan and execution statistics for the statement that produced this streaming result set. These can be requested by setting ExecuteSqlRequest.query_mode and are sent only once with the last response in the stream. This field will also be present in the last response for DML statements.

setValues(int index, Value value)

public PartialResultSet.Builder setValues(int index, Value value)

A streamed result set consists of a stream of values, which might be split into many PartialResultSet messages to accommodate large rows and/or large values. Every N complete values defines a row, where N is equal to the number of entries in metadata.row_type.fields.

Most values are encoded based on type as described here.

It is possible that the last value in values is "chunked", meaning that the rest of the value is sent in subsequent PartialResultSet(s). This is denoted by the chunked_value field. Two or more chunked values can be merged to form a complete value as follows:

• bool/number/null: cannot be chunked
• string: concatenate the strings
• list: concatenate the lists. If the last element in a list is a string, list, or object, merge it with the first element in the next list by applying these rules recursively.

• object: concatenate the (field name, field value) pairs. If a field name is duplicated, then apply these rules recursively to merge the field values.

  Some examples of merging:

  Strings are concatenated.

  "foo", "bar" => "foobar"

  Lists of non-strings are concatenated.

  [2, 3], [4] => [2, 3, 4]

  Lists are concatenated, but the last and first elements are merged

  because they are strings.

  ["a", "b"], ["c", "d"] => ["a", "bc", "d"]

  Lists are concatenated, but the last and first elements are merged

  because they are lists. Recursively, the last and first elements

  of the inner lists are merged because they are strings.

  ["a", ["b", "c"]], [["d"], "e"] => ["a", ["b", "cd"], "e"]

  Non-overlapping object fields are combined.

  {"a": "1"}, {"b": "2"} => {"a": "1", "b": 2"}

  Overlapping object fields are merged.

  {"a": "1"}, {"a": "2"} => {"a": "12"}

  Examples of merging objects containing lists of strings.

  {"a": ["1"]}, {"a": ["2"]} => {"a": ["12"]}

  For a more complete example, suppose a streaming SQL query is yielding a result set whose rows contain a single string field. The following PartialResultSets might be yielded:

  { "metadata": { ... } "values": ["Hello", "W"] "chunked_value": true "resume_token": "Af65..." } { "values": ["orl"] "chunked_value": true "resume_token": "Bqp2..." } { "values": ["d"] "resume_token": "Zx1B..." }

  This sequence of PartialResultSets encodes two rows, one containing the field value "Hello", and a second containing the field value "World" = "W" + "orl" + "d".
