getNumberOfTableRows()

template<typename ALLOC >

static size_t zserio::ValidationSqliteUtil< ALLOC >::getNumberOfTableRows ( SqliteConnection &  connection, std::string_view  attachedDbName, std::string_view  tableName, const ALLOC &  allocator  )

inlinestatic

Gets number of rows in the given SQLite table.

Parameters

connection	Database connection to use.
attachedDbName	Attached database name if table is relocated in different database.
tableName	Name of the table to get column types of.
allocator	Allocator to use for the query string composition.

Returns

Number of rows.

Exceptions

SqliteException

if the table does not exist.

Definition at line 48 of file ValidationSqliteUtil.h.

getTableSchema()

template<typename ALLOC >

static void zserio::ValidationSqliteUtil< ALLOC >::getTableSchema ( SqliteConnection &  connection, std::string_view  attachedDbName, std::string_view  tableName, TableSchema &  tableSchema, const ALLOC &  allocator  )

inlinestatic

Gets a map of column names to column description for given SQLite table.

Parameters

connection	Database connection to use.
attachedDbName	Attached database name if table is relocated in different database.
tableName	Name of the table to get column types of.
tableSchema	Schema to fill.
allocator	Allocator to use for the query string composition.

Definition at line 80 of file ValidationSqliteUtil.h.

isColumnInTable()

template<typename ALLOC >

static bool zserio::ValidationSqliteUtil< ALLOC >::isColumnInTable ( SqliteConnection &  connection, std::string_view  attachedDbName, std::string_view  tableName, std::string_view  columnName, const ALLOC &  allocator  )

inlinestatic

Check if the column is present in the given SQLite table. Note that this method also detect hidden SQLite columns, which are not visible using standard PRAGMA table_info query.

Parameters

connection	Database connection to use.
attachedDbName	Attached database name if table is relocated in different database.
tableName	Name of the table to get column types of.
columnName	Name of the column to check.
allocator	Allocator to use for the query string composition.

Returns

Returns true if the column is present in the table, even if the column is hidden. Otherwise returns false.

Definition at line 129 of file ValidationSqliteUtil.h.

sqliteColumnTypeName()

template<typename ALLOC >

static const char * zserio::ValidationSqliteUtil< ALLOC >::sqliteColumnTypeName ( int  columnType )

inlinestatic

Gets name of the given SQLite column type.

Parameters

columnType

SQLite column type.

Returns

SQLite column type name.
