Methods

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()

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
StructTypeOrBuilder

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.

.google.spanner.v1.Transaction transaction = 2;

Returns
Type	Description
Transaction	The transaction.

getTransactionOrBuilder()

public abstract 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;

Returns
Type	Description
TransactionOrBuilder

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" } },
 ]

.google.spanner.v1.StructType undeclared_parameters = 3;

Returns
Type	Description
StructType	The undeclaredParameters.

getUndeclaredParametersOrBuilder()

public abstract 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" } },
 ]

.google.spanner.v1.StructType undeclared_parameters = 3;

Returns
Type	Description
StructTypeOrBuilder

hasRowType()

public abstract 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.

hasTransaction()

public abstract 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.

hasUndeclaredParameters()

public abstract 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
Type	Description
boolean	Whether the undeclaredParameters field is set.
