This node allows a user to create a new database table either manually or based on the specification of a KNIME input data table (see "Use dynamic settings" below). The node supports advanced options such as null or not null, primary key or unique keys, default SQL type mapping based on column name or KNIME data type, and default key definitions based on column names.
Tick the "Use dynamic settings" option to enable the dynamic settings behavior. Once enable it
allows to dynamically define the SQL type of the columns as well as the assignment of columns to primary
or unique keys. All dynamic settings which are made via the "Dynamic Type Settings" and
"Dynamic Column Settings" tab are applied to the data table specification of the input data table.
The mappings defined in the Name-Based SQL Type Mapping have a higher priority than the mappings defined in the KNIME-Based SQL Type Mapping. If no mapping is defined in both Name-Based SQL Type mapping and KNIME-Based SQL Type Mapping, then the default mapping is used.
While in dynamic settings mode the "Columns" and "Keys" tab become read-only to allow you a preview of the dynamic settings.
While in dynamic settings mode the "Columns" tab becomes read-only to allow you a preview of the dynamic settings.
While in dynamic settings mode the "Keys" tab becomes read-only to allow you a preview of the dynamic settings.
In the Name-Based SQL Type Mapping, a user can define the default SQL type mapping for a set of columns based on the column names. Use the "Add" button to add a new row containing the name pattern of the columns that should be mapped. The name pattern can either be a string with wildcard or a regular expression. The mappings defined in the Name-Based SQL Type Mapping have a higher priority than the mappings defined in the KNIME-Based SQL Type Mapping.
Supported wildcards are * (matches any number of characters) and ? (matches one character) e.g. KNI* would match all strings that start with KNI such as KNIME whereas KNI? would match only strings that start with KNI followed by a fourth character. Double click the "Name Pattern" cell to edit the pattern.
