public ResultSetMetadata()

Method Detail

getRowType

public StructType getRowType()

Indicates the field names and types for the rows in the result set. For example, a SQL query like `"SELECT UserId, UserName FROM Users"` could return a `row_type` value like: "fields": [ { "name": "UserId", "type": { "code": "INT64" } }, { "name": "UserName", "type": { "code": "STRING" } }, ]

Returns:

value or null for none

setRowType

public ResultSetMetadata setRowType(StructType rowType)

Indicates the field names and types for the rows in the result set. For example, a SQL query like `"SELECT UserId, UserName FROM Users"` could return a `row_type` value like: "fields": [ { "name": "UserId", "type": { "code": "INT64" } }, { "name": "UserName", "type": { "code": "STRING" } }, ]

Parameters:

rowType - rowType or null for none

getTransaction

public Transaction getTransaction()

If the read or SQL query began a transaction as a side-effect, the information about the new transaction is yielded here.

Returns:

value or null for none

setTransaction

public ResultSetMetadata setTransaction(Transaction transaction)

If the read or SQL query began a transaction as a side-effect, the information about the new transaction is yielded here.

Parameters:

transaction - transaction or null for none

set

public ResultSetMetadata set(java.lang.String fieldName,
                             java.lang.Object value)

Overrides:

set in class com.google.api.client.json.GenericJson

clone

public ResultSetMetadata clone()

Overrides:

clone in class com.google.api.client.json.GenericJson
