Method Detail

hasRowType

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:

Whether the rowType field is set.

getRowType

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:

The rowType.

getRowTypeOrBuilder

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" } },
     ]
 

.google.spanner.v1.StructType row_type = 1;

hasTransaction

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:

Whether the transaction field is set.

getTransaction

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;

Returns:

The transaction.

getTransactionOrBuilder

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;

hasUndeclaredParameters

boolean hasUndeclaredParameters()

 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:

Whether the undeclaredParameters field is set.

getUndeclaredParameters

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:

The undeclaredParameters.

getUndeclaredParametersOrBuilder

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": [
       { "name": "UserId", "type": { "code": "INT64" } },
       { "name": "UserName", "type": { "code": "STRING" } },
     ]
