Properties

BulkInserts

Instead of using single values inserts (with a INSERT INTO .. VALUES () statement), data is inserted in batches using a INSERT INTO .. VALUES (), (), () syntax. All other connectors already use the batch variant, but SQLite is optimized for single inserts and sometimes has issues with a bigger amount of parameters passed into a sql statement. Using bulk inserts is not compatible with older version (SQLite < 3.15.0)

Declaration
    public bool BulkInserts { get; set; }
Property Value
TypeDescription
bool

ConnectionType

The database type for the connection manager.

Declaration
    public override ConnectionType ConnectionType { get; protected set; }
Property Value
TypeDescription
ConnectionType
Overrides
ETLBox.DbConnectionManager<System.Data.SQLite.SQLiteConnection, System.Data.SQLite.SQLiteTransaction, System.Data.SQLite.SQLiteParameter>.ConnectionType

MaxParameterSizeSql

Returns the maximum amount of parameters that can be passed into a sql query.

Declaration
    public override int MaxParameterSizeSql { get; set; }
Property Value
TypeDescription
int
Overrides
ETLBox.DbConnectionManager<System.Data.SQLite.SQLiteConnection, System.Data.SQLite.SQLiteTransaction, System.Data.SQLite.SQLiteParameter>.MaxParameterSizeSql

ModifyDBSettings

Will set the PRAGMA synchronous = OFF and PRAGMA journal_mode = MEMORY settings before the bulk insert. The changes will be reverted after the bulk insert operation.

Declaration
    public bool ModifyDBSettings { get; set; }
Property Value
TypeDescription
bool

QB

The quotation begin character that is used in the database. E.g. SqlServer uses: '[' and Postgres: '"'

Declaration
    public override string QB { get; protected set; }
Property Value
TypeDescription
string
Overrides
ETLBox.DbConnectionManager<System.Data.SQLite.SQLiteConnection, System.Data.SQLite.SQLiteTransaction, System.Data.SQLite.SQLiteParameter>.QB

QE

The quotation end character that is used in the database. E.g. SqlServer uses: ']' and Postgres: '"'

Declaration
    public override string QE { get; protected set; }
Property Value
TypeDescription
string
Overrides
ETLBox.DbConnectionManager<System.Data.SQLite.SQLiteConnection, System.Data.SQLite.SQLiteTransaction, System.Data.SQLite.SQLiteParameter>.QE

SupportDatabases

Indicates if database server does support multiple databases. A database in ETLBox means a schema in MySql.

Declaration
    public override bool SupportDatabases { get; protected set; }
Property Value
TypeDescription
bool
Overrides
ETLBox.DbConnectionManager<System.Data.SQLite.SQLiteConnection, System.Data.SQLite.SQLiteTransaction, System.Data.SQLite.SQLiteParameter>.SupportDatabases

SupportProcedures

Indicates if the database supports procedures

Declaration
    public override bool SupportProcedures { get; protected set; }
Property Value
TypeDescription
bool
Overrides
ETLBox.DbConnectionManager<System.Data.SQLite.SQLiteConnection, System.Data.SQLite.SQLiteTransaction, System.Data.SQLite.SQLiteParameter>.SupportProcedures

SupportSchemas

Indicates if the database supports schemas In MySql, this is false because the schema here is a database in ETLBox. Use SupportDatabases instead

Declaration
    public override bool SupportSchemas { get; protected set; }
Property Value
TypeDescription
bool
Overrides
ETLBox.DbConnectionManager<System.Data.SQLite.SQLiteConnection, System.Data.SQLite.SQLiteTransaction, System.Data.SQLite.SQLiteParameter>.SupportSchemas
