getRowType()
public abstract 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;
Returns | |
---|---|
Type | Description |
StructType | The rowType. |
getRowTypeOrBuilder()
public abstract StructTypeOrBuilder getRowTypeOrBuilder()

getTransaction()
public abstract Transaction getTransaction()
If the read or SQL query began a transaction as a side-effect, the information about the new transaction is yielded here.

getUndeclaredParameters()
public abstract 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" } },
