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" } },
]
.google.spanner.v1.StructType row_type = 1;
public StructTypeOrBuilder getRowTypeOrBuilder()
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" } },

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.
.google.spanner.v1.Transaction transaction = 2;
public TransactionOrBuilder getTransactionOrBuilder()
If the read or SQL query began a transaction as a side-effect, the
information about the new transaction is yielded here.
.google.spanner.v1.Transaction transaction = 2;
public StructType getUndeclaredParameters()
A SQL query can be parameterized. In PLAN mode, these parameters can be
undeclared. This indicates the field names and types for those undeclared
parameters in the SQL query. For example, a SQL query like "SELECT * FROM
Users where UserId = @userId and UserName = @userName " could return a
undeclared_parameters value like:
"fields": [
{ "name": "UserId", "type": { "code": "INT64" } },
{ "name": "UserName", "type": { "code": "STRING" } },
]
.google.spanner.v1.StructType undeclared_parameters = 3;
| Returns |
|---|
| Type | Description |
StructType | The undeclaredParameters.

public StructTypeOrBuilder getUndeclaredParametersOrBuilder()
A SQL query can be parameterized. In PLAN mode, these parameters can be
undeclared. This indicates the field names and types for those undeclared
parameters in the SQL query. For example, a SQL query like "SELECT * FROM
Users where UserId = @userId and UserName = @userName " could return a
undeclared_parameters value like:
"fields": [

public boolean hasRowType()
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" } },

.google.spanner.v1.StructType row_type = 1;
| Returns |
|---|
| Type | Description |
boolean | Whether the rowType field is set.

public boolean hasTransaction()
If the read or SQL query began a transaction as a side-effect, the
information about the new transaction is yielded here.
.google.spanner.v1.Transaction transaction = 2;
| Returns |
|---|
| Type | Description |
boolean | Whether the transaction field is set.
