This type can't be constructed in user code and is always retrieved from storages::sqlite::Client

| ResultSet storages::sqlite::Savepoint::Execute | ( | const Query & | query, |
| const Args &... | args ) const |
Executes a statement.
Fills placeholders of the statement with args..., Args are expected to be of supported types. See SQLite supported types for better understanding of Args requirements.
| Args | Types of parameters to bind |
| query | SQL query to execute |
| args | Parameters to bind to the query |
Definition at line 112 of file savepoint.hpp.
| ResultSet storages::sqlite::Savepoint::ExecuteDecompose | ( | const Query & | query, |
| const T & | row ) const |
Executes a statement, decomposing the row.
Decomposes the fields of the row and binds them as parameters to the query. See SQLite supported types for better understanding of T requirements.
| T | Type of the row to decompose |
| query | SQL query to execute |
| row | Row object to decompose and bind |
Definition at line 125 of file savepoint.hpp.
| void storages::sqlite::Savepoint::ExecuteMany | ( | const Query & | query, |
| const Container & | params ) const |
Executes a statement multiple times.
Iterates over the container and executes the query for each element. Container is expected to be a std::Container, Container::value_type is expected to be an aggregate of supported types. See MySQL supported types for better understanding of Container::value_type requirements.
| Container | Type of the container holding rows |
| query | SQL query to execute |
| params | Container of rows to bind and execute |

| const Args &... | args ) const |
Executes a statement and returns a cursor for iterating over results.
Fills placeholders of the statement with args..., Args are expected to be of supported types. See SQLite supported types for better understanding of Args requirements.
| T | Type of the result rows |
| Args | Types of parameters to bind |
| batch_size | Number of rows to fetch per batch |
| query | SQL query to execute |
| args | Parameters to bind to the query |

| Savepoint storages::sqlite::Savepoint::Save | ( | std::string | name | ) | const |
Creates a wrapped savepoint with specified name.
| name | Name of the savepoint |
