Acts on the actual DB structure or on the data (although without handling data) depending on the nature of the query and the database. The SQLBuilder tool helps you write easily your SQL statements.
tDBSQLRow is the generic component for database query. It executes the SQL query stated onto the specified database. The row suffix means the component implements a flow in the job design although it does not provide output. For performance reasons, specific DB component should always be preferred to the generic component.
To use this component, relevant DBMSs' ODBC drivers should be installed and the corresponding ODBC connections should be configured via the database connection configuration wizard.
